14. Pip—ER GyMNopHYLLUM, C. DC. in Records Bot. Surv. Ind. 
VI. 6 (1912). Branches glabrous, dark brown and black-dotted when 
dry, the spiciferous up to 2 mm. thick; collenchyma partly or quite 
libriform in distinct bundles. Leaves moderately long petioled, gla- 
brous; limb membranous when dry, black-dotted underneath, up to 
16 cm. long and 5:5 cm wide, elliptic-lanceolate, acutely acuminate 
at the top, acute and slightly inequilateral at the base; 6-pli- 
nerved, the central nerve emitting 3 ascendent nerves of which 2 on 
one side, the uppermost from nearly 25:5 mm. above the base, and 
having on each side of it one ascendent short nerve free from the 
base; petiole up to 10°5 mm. long with basal sheath. Peduwncles 
glabrous, 12°5 mm. long. Spike: ? nearly half as long as the limb ; 
rhachis fulvescent-hirsute ; bract glabrous, rounded, 1°5 mm. in

V1.7 (1912). Branches sparingly puberulous, drying brown, the spici- 
ferous 1 mm. thick; collenchyma libriform in distinct bundles; a 
single central lysigenous canal. Leaves shortly petioled; limb rigid 
when dry, copiously pellucid-dotted, 755—8:5 em. long and 2°5 cm. 
wide, glabrous on both surfaces, ovate-lanceolate, acutely atten- 
uate, the extreme base acute and slightly inequilateral ; 5-plinerved, 
the central nerve emitting 2 ascendent opposite nerves 8°5—10°5 
mm. above the base and having on each side of it one ascendent 
nerve free from the base ; petiole puberulous, 8°4 mm. long, of which 
less than 1 mm. between the sides of the limb, sheath basal. Pe- 
duncles slender, glabrous, 19mm. long. Spike: 9 about 3°5 cm. long 
when fruiting, rhachis densely hirsute ; bract glabrous, its limb round, 
1-5 mm. in diam., sessile at its centre; ovary free, glabrous; stigmas 
mostly 4, rounded and short. Berry sessile, globose-ovate, nearly 
4-2 mm. long, drying black.
