Tectaria nayarii Mazumdar

Family Name:	Tectariaceae
Synonyms:	Heterogonium pinnatum (Copel.) Holttum, Stenosemia pinnata Copel.

Tectaria nayarii is a small fern found growing on rocks and limestones. It produces two types of fronds; broad sterile fronds and narrow fertile fronds. The sterile fronds are deeply lobed, elongates with age. Bulbils are small plantlets that form near the base of leaflets or along the costae. The fertile fronds are lobed attached to a long stalk. Sori are arranged along the margins of the fronds, visible on both sides.

Description and Ethnobotany

Growth Form	It is a small fern that is often found growing on rocks and limestones.
Foliage	"Its foliage are strongly dimorphous, and form two types of fronds; sterile and fertile fronds. When young, the sterile fronds are lobed, broad, deltoid-shaped and elongates with age. They measure between 15 - 30 cm long, attached to a dark purplish brown stalk of equivalent length. At the tip of the frond, the foliage is deeply lobed into deltoid segments. Approaching the centre of the frond, the segments develops into elongated pairs of leaflets which are slightly lobed, joined at the base. The basal leaflets developed pronounced lobes which are broad, obtuse with a smooth margin, measuring 12 x 4 cm with a stalk of 2mm long. Bulbils are form are produced near the base of leaflets or along the costae. The fertile fronds are much narrower, attached to a long stalk of at least 45 cm in length. The fronds are 15 cm long, deeply lobed - each less than 2 mm wide."
Reproductive Parts - non-flowering plant	The sporangia (spore-bearing structures) are borne on the narrow fertile fronds spreads beyond the margins, making it visible on both sides of the frond.

Habitat	Found on limestone in shade and alluvial forest in limestone areas.
Cultivation	Grows well in partial shade, in constantly moist media.
