Description and Ethnobotany
| Growth Form | Terrestrial orchid with creeping underground rhizomes and closely-set erect stems, up to 2m height. |
|---|---|
| Foliage | Leaves strap-shaped, bi-lobed, 12cm by 3cm, wider near base, sessile (stalkless), found along stems except near top of plant. |
| Flowers | Fairly large (7-8cm by 7-8cm), slightly fragrant, petals white to creamy, lower lip purple-veined with yellow centre. Produced in terminal inflorescences (10-15cm tall), each of which may hold up to 50 successively-developing flower buds, but which usually bears 1-2 open flowers at a single time. Flowers open in morning, lasting for a few hours, typically fading by noon or early afternoon. Blooming tends to occur a few days after rain. |
| Fruit | Explosive seedpods with tiny dust-like seeds. Mature seeds formed 8 weeks after flower pollination. |
| Others - Plant Morphology | Local Conservation Status: Native, common, previously sighted at Bukit Timah Nature Reserve, Kent Ridge Park, Western Catchment, Pulau Ubin and Pulau Tekong. |
| Habitat | Open dry spots on secondary forest floor, Adinandra Belukar (degraded secondary forest), sometimes on sandy soils near roadsides. |
| Cultivation | Provide well-drained soils. Propagate by seeds. |
| Etymology | Genus epithet 'Bromheadia' named after British landowner and mathematician Sir Edward Thomas Bromhead (1789-1855), best remembered as patron of the self-taught British mathematician and physicist George Green (1793-1841). Species epithet 'finlaysoniana' named in honour of Scottish army surgeon and naturalist Dr George Finlayson (1790-1823), who travelled to Siam and Cochin-China in 1821, and wrote an interesting journal about his experience, which was edited and published after his death by Sir Thomas Stamford Raffles (1781-1826). |
| Ethnobotanical Uses | Food (Herb or Spice) Others: Roots boiled into herbal wine and drunk to treat rheumatism and joint pain. Flowers used as heart tonic. |
