Abstract:
A botanic garden is essentially a museum of living plants.  The word 'museum' is derived from the name of the Greek goddesses of learning and the arts; thus a museum is a place devoted to the pursuit of such studies.  A botanic garden is primarily a place where plants are grown for scientific study. But a garden differs from a museum in the fact that objects in it are living and growing, thus need the attention of horticulturists. Horticulture is in part applied botanical science: but it is also in part an art, and the aesthetic aspects of horticulture therefore find expresion in any garden.  But I would say that a garden cannot be accorded the title 'botanic' unless it is a place where plant sciences of one kind or another are studied, and where the results of such study are expressed both in publications and in an arrangement and labelling, which conveys information to visitors as well as aesthetic enjoyment. A park is a place designed for recreation, not for study or education, and the plants in it are selected and arranged solely for their aesthetic effect: here the horticulturist alone has charge.  Some of the older and smaller botanic gardens are now in effect parks, and the distinction between botanic garden and park is not generally understood by the public. sometimes also not by politicians. To understand the present situation, one must look a little into the past.

An account of Caetano Xavier dos Remedios Furtado's academia career, his taxonomic work on Malayan palms and the African genus Hyphaene is given, together with a complete list of his publications on palms and a resume of his travels in connection with his research on palms.

Abstract:
The Herbarium dates back to the establishment of the Botanic Gardens on its present site.  By 1875, H.J. Murton already had a collection of dried specimens, which was temporarily housed in his office until proposed herbarium building was erected, and from the start he established a library having ordered from England a 'good collection of standard botanical works' (Annual report for 1875).  He reported that by 1879 the herbarium comprised 3,000 named specimens (Annual Report for 1879).  Most of his collections were made from Singapore, Perak, Selangor and Malacca but he acquired valuable old herbarium specimens, mostly of Indian and Nepalese plants, that had been in J. Collins possession in Singapore but which had originally been part of Ward's herbarium held by the Linnaean Society of London.  These included Wallich's specimens collected from Penang, Malacca and Singapore, as well as the oldest specimens in the Singapore herbarium, those collected by Moravian Missionaries in 1790 (Annual Report for 1889).  

Abstract:
Two new species of Pandanus from the Caroline Islands are described : P. amissus (Kosrae Island) and P. lorencei (Palau Island).  New data on P. kanehirae and Freycenetia villalobosii, both from Palau, are also reported.  The staminate flower of P. whitmeeanus is described for the first time.  The taxonomic relationships of P. whitmeeanus within the genus Pandanus are reassessed.

Abstract:
The new combination Garcinia cymosa (K. Schum.) I.M. Turner & P. F. Stevens is made, based on Tripetalum cymosum K.Schum., for a tree from New Guinea and the Bismarck Archipelago.  The oldest name available for the species is Leuconotis tenuifolia Engl., but this epithet has already been used for another species of Garcinia.  A columnar form of the tree that is finding success in tropical horticulture, described as forma pendulum Larterb., is also provided with a combination in Garcinia and is lectotypified.

Abstract:
A new species in Sect. Sarcosiphon of Thismia, T. goodii Kiew, with remarkable blue perianth lobes, is described from Sabah, Borneo.

Abstract:
Bukit Bauk is a small, isolated, coastal hill range that is part of the Terengganu Hills situated at the southern end of the East Range in Peninsular Malaysia.  Four vegetation types were distinguished on Bukit Bauk, namely, lowland dipterocarp forest, peat swamp forest, hill dipterocarp forest and vegetation of disturbed areas.  Its floristic diversity was investigated leading to a checklist of plants.  Its flora comprises at least 638 species (7.7% of the total flora of the Peninsular Malaysia) belonging to 285 genera and 103 families.  The most speciose families are the Euphorbiaceae ( 59 species), Dipterocarpaceae ( 43 species ), Rubiaceae ( 36 species ), Palmae and Guttiferae ( each with 31 species ).  Of these, 91 taxa are endemic ( 87 species, 1 subspecies and 1 variety ), about 3.6% of the total number endemic taxa in the Peninsular.  This study confirms that Bukit Bauk Forest Reserve with a relatively small area of 7,596 ha is a species-rich area with a high degree of endemism and is an important component of the flora in Peninsular Malaysia that should be conserved by being totally protected.

Book Review

Abstract:
The genus Alocasia (Schott) G.Don (Araceae) is revised for the Philippine Islands.  Fourteen species are recognised, of which four are new to science.  A key to the species is provided.  All except Alocasia macrorrhizos (L.) G.Don are endemic.  Alocasia wenzelii Merr. is placed in the synonymy of A. zebrina Schott ex van Houtte.  Alocasia manilensis Engl. and A. warburgii Engl. are synonyms of A. heterophylla (Presl) Merr. Alocasia reversa N.E. Brown is Bornean, not Philippines as originally attributed.  The new species (A. boyceana A. Hay, A. clypeolata A. Hay, A. scalprum A. Hay and A. ramosii A. Hay), the frequently misinterpreted Alocasia heterophylla and the very rare A. atropurpurea Engl. are illustrated.  Brief notes are made on horticultural value, conservation status, local endemicity and relationships of Philippines Alocasia. Where possible, cultivars recognised by the international horticultural community are ascribed to species.

Abstract:
Pollination of a canopy tree of two species, Vatica aff. parvifolia and V. micrantha (Dipterocarpaceae) was investigated in Sarawak, Malaysia.  Flowers of the two species open in the evening, and last for + 2 days.  Rewards are petal tissue and pollen.  In V. aff. parvifolia, pollen was removed from anthers on the first day, and deposited on stigmas on the second day, which suggests that the flowers are protandrous.  Most (76%) flower visitors were beetles (Chrysomelidae), 25% of which carried pollen.  The beetles mated inside flowers and often touched anthers and stigmas.  These suggest that the beetles are pollinaters.  Pollination of V. micrantha rarely occured, because of few pollen grains were removed from anthers and deposited in stigmas.  Dominant (71%) flower visitors were weevils (Apionidae and Curculionidae), 9% of which carried pollen.  The weevils laid eggs from outside flowers.  Bagging treatment increased fruit set in V. micrantha.  This suggests the negative effects, such as seed predation, of the weevils on fruit set.

Abstract:
Scanning electron microscopy was used to examine the trichome morphology on the leaves of 24 species of Durio.  Glandular trichomes and non-glandular trichomes are present on the abaxial leaf surface.  Stellate hairs can be found on the abaxial leaf surface of D. affinis, D. graveolens, D. oblongus, D. oxyleyanus, D. singaporensis and D. zebithinus.  Trichome morphology can be used to distinguish the Durio species studied.  D. carinatus can be distinguished by the presence of only peltate scales on the abaxial leaf surface.  The other species can be divided into three major groups based on the density and distribution of the peltate scales and stellate hairs.

Abstract:

Abstract:
One new species, Olea moluccensis Kiew from the islands of Buru and Taliabu, is described and new combinations are made for three Philippine species, O. gitingensis (Elmer) Kiew, O. obovata (Merr.) Kiew and O. rubrovenia (Elmer) Kiew, all originally described as Linocieras.  Olea decussata (Heine) Kiew is synonymus with O. ribrovenia, Linociera lauterbachii Lingelsh. with Olea paniculata R. Br.; L. longifolia Merr. with O. gitingensis, and L. pallida (Merr.) Merr. and L. philippinensis Merr. with O. borneensis Boerl.

Abstract:
The identities of two closely related species of Euphorbia naturalised in Southeast Asia from the New World tropics are considered. The name Euphorbia heterophylla L. has been consistently misapplied in the Malay Peninsula to plants of Euphorbia cyathophora Murray. True Euphorbia heterophylla is found as a garden escape and weed of waste ground, but is not as common in the Malay Peninsula as E. cyathophora. The differences between the two species are summarised.

Abstract:
Study of three begonia populations in montane forest at Cameron Highlands, Pahang, confirmed that hybridization had occurred between Begonia decora and B. venusta.  The hybrids are fertile and calculation of the hybrid index indicates that introgression had taken place.  Two populations are stable and are represented by hybrid swarms.  Plants of the two parents were not located in the vicinity of these two populations  The third, comprising both parents and hybrids, is unstable and its composition has changed over the years.  A further two populations have been destroyed by habitat disturbance, which is prevalent at Cameron Highlands.

Abstract:
Eupatorium catarium Veldk. (Compositae) is a new name for Eupatorium clematideum Griseb., non Sch.Bip.,also known as Praxelis clematidea R.M.King & H. Rob.. The species has been introduced in S. China and Queensland, Australia, where it appears to be spreading rapidly.

Abstract:
A total of 381 butterfly species have now been recorded in Singapore of which 18 are new records since 1990. Of this total, 236 species (62%) were recorded during the present survey. All except 8 (3%) of these occur within the Nature reserves and 148 (63%)  were recorded within the Nature reserves. A total of 74 species (31%) within the Reserves were considered very rare.

Abstract:
Forty-one species of phasmids found in Singapore extant as well as extinct are listed and aspects of their conservation discussed. Eleven species are still relatively common and are widely distributed especially within the Central Catchment Nature Reserves. Eleven species exist in only very isolated pockets within the Central Catchment Nature Reserves. One speceis has been found only in Punggol area. A further ten species are very rare and in almost a decade of studying these insects only one or two specimens have been found in Singapore. An additional eight species have not been seen or recorded for at least 30 years and are best described as extinct in Singapore.

Abstract:
A total of 37 species of semiaquatic bugs were recorded from the forest during the survey of the Nature Reserves. 78% were found in the Nee Soon Swamp Forest that also has the highest percentage of the area or threatened species on the island. Bukit Timah Nature Reserves has the lowest diversity.  Three forest-dependent species, Cylindrostethus malayensis, Ventidius hungerfordii and Esakia fernandoi previously recorded from Singapore were not found and hence are, presumed extinct. Eight species are new records for Singapore.

Abstract:
Of the 36 species of aquatic beetles recognised here, 17 are rated threatened.  Two rare species of Microdytes (Dytiscidae) were only found in a small springlet in the Bukit Timah Nature Reserve.  Nee Soon Swamp Forest has the highest diversity as well as the highest number of locally threatened water beetle species in the Nature Reserves.

Abstract:
An account is given of Odonata collected during the survey of the Nature Reserves. Most of the species described from Singapore material in A.R. Wallace's collection in 1856 still occur. A total of 79 species have been recorded within the Nature Reserves, including an endemic damselfly, Drepanosticta quadrata. Eight species are known only from Nee Soon Swamp Forest.

 

Abstract:
The diversity of mammals, reptiles and amphibians is still high in the Nature Reserves with a total of 141 indigenous species recorded in the past decade, comprising 44 mammals, 72 reptiles and 25 amphibians. During the four-year survey, there were 10 additions to Singapore's checklist of mammals, reptiles and amphibians, and 13 other species were rediscovered compared with four and ten, respectively, recorded during the six-year period prior to the survey. This is a clear indication that our Nature Reservcs may still hold many species that are either not recorded for Singapore or are thought to be extinct. The Nature Reserves are probably the last refuge for 74 forest-dependent species and 80 species whose populations are of such low numbers that they are threatened with extirpation. Bukit Timah, Nee Soon and MacRitchie are the richest in biodiversity and, hence, are key areas for conservation. They should be set aside as core zones with the incorporation of Mandai and Lower Peirce.

Abstract:
The begonia flora of limestone hills in Sabah is extremely biodiverse with several begonias being found at a single locality, the great majority of which have extremely local distributions. For example, on Bukit Dulong Lambu (better known as Gomantong Cave) four species coexist. Two are new species. Begonia gomantongensis and B postarii for which descriptions are provided. The former is endemic to Bk. Dulong Lambu, as is B. malachosticta Sands. The fourth species, B. gueritziana Gibbs is widespread on limestone, as well as on other rock tvpes. Field observations show that niche partitioning occurs between these four species based on light conditions (that also relate to severity of water stress) and substrate. All four begonias are vulnerable to habitat changes - B. gomantongensis and B. postarii that grow in the damp and shaded conditions around the base of the hill are vulnerable to clearance or disturbance to the tree canopy, while all species are endangered by the periodic forest fires. Indeed, the summit vegetation of Bk. Dulong Lambu has still not recovered from the 1983 fires.

Abstract:
A survey on termites in the Singapore Botanic Gardens Rain Forest included termite collection and quantitative assessment of vegetation, dead trees and wood litter in 15 random sample plots, which covered 7.5% area of the forest.  Termite infestation was high in the northern zone, moderate in the central and light in the southern zones. The abundance of termite-infested microhabitats shows a positive relationship with the number of big trees, dead standing trees and ground timber, and a negative relationship with the number of herbs.  A total of 22 termite species were found.  Three genera of gallery-forming temites identified were  Bulbitermes, Nasutitermines and Microcerotermes. The major fungus-growing genera were Macrotermines, Odontotermes and Microtermes. The ground-nesting genera included Termes, Dicuspiditermes, Hospitalitermes and Prohamitermes. The other genera found were Coptotermes, Schedorhinotermes, Subulitermes and Procapritermes.  Three new records for Singapore are Bulbitermes borneensis, B. constrictus and Microcerotermes crassus.  Microcerotermes and Nasutitermes are involved in the self-pruning of trees. The Bulbitermes, Macrotermes and Odontotermes are dominant in ground timber. The different species richness and uneven distribution of termites in different parts of the forest is attributed, not only to the differences in forest structure and flora, but also the degree to which the forest floor space has been depleted for visitor and horticultural activities.

Abstract:
Unique elements of the flora of the Batu Tengar Cave include Begonia keithii (Begoniaceae), a new species endemic to this hill, and the phytogeographic affinities of its flora, which are a new species which are not only with the nearby Mandai limestone hills, but also with limestone in Kalimantan (Borneo) and the Philippines. Notes on species of special interest, Euphorbia lacei (Euphorbiaceae), Impatiens winkleri (Balsaminaceae) and Paraboea madaiensis (Gesneriaceae) are given.

Abstract:
Alocasia (Schott) G. Don is revised for West Malesia and Sulawesi. Thirty one species are recognised, including one extremely variable species, A Iongiloba Miq. s.l., in which seven incompletely delineable informal entities are further recognised. Ten species are new to science. The history, geography, ecology and morphology of the genus and conservation status of its species are discussed and foci for further study are briefly delineated. A key to species is provided. Approximately 25% of names are epi- or neotypified owing to lack of adequate original material - a situation deriving mainly from the horticultural history of the genus. New synonyms include A. margaritae L. Linden & Rodigas, A. ovalifolia Ridl., A. crassinervia Engl., A. puber (Hassk.) Schott; A. imperialis L. Linden, A. guttata N.E. Br., A. villeneuvei L. Linden; A. scabruiscula N.E. Brown; A. porphyroneura Hallier f. = A. princeps W. Bull; A. grandis N.E. Br. = A. macrorrhozos (L.) G.
