16. ОвевомА FALCATA, King and Pantling in Journ. As. Soċ., Bengal, 
LXIV, pt. 2, p. 329. 
Caulescent, tufted. Stzms 5 in. long, flexuose. Leaves faleate, ensiform, acute, 1 to 
2:5 in. long and :9 to :25 in. broad. Inflorescencs erect, nearly as long as the 
stem and much longer than the leaves ; the  pedunci? very short, terete, less than 
half as long as the uppermost leaf, bracteate; raceme  many-flowered ; floral Фғасі 
equalling and sheathing the stalked ovary, ovate, sub-acute, erose. Flowers yellowish- 
green, minute (‘05 in. long), crowded, sub-verticellate. Sepals ovate, entire, reflexed or 
spreading. Petuls linear-oblong, blunt, entire, Lip twice as long as the sepals, broadly 
oblong in general outline, flat except for a slight depression near its base and just 
under the column; side lobes small, triangular, pointing outwards ; the terminal lobe 
with two deep lanceolate slightly diverging terminal lobules separated by a wide 
sinus with a narrow but rounded edentate apex. Column with two fleshy wings. 
Anther-cap membranous. Pollinia ovate, compressed, and of a dark orange colour. 
Choongthang in the Sikkim-Himalaya, at an elevation of 6, 000 feet; Pantling 
No. 218; in flower during August. 
This resembles O. longilabris, King and Pantling in having a winged column. But 
it is a larger plant than that, and its lip is differently lobed; the petals also are 
broader and their apices are not truncate as in that species. This also resembles 0. 
Manni Hook. fil. (Ie. Plantar., t. 2003), but has narrower petals which are quite entire. 
Pirate 14.—Oberonia falcata, King and Pantling. Two plants, of natural size. Fig. 1 front view

Stem very short. Leaves narrowly oblong, sub-ensiform, flaccid, “75 to 5 in. long 
and “25 to "65 in. broad. Inflorescence erect, longer than the leaves ; its peduncle short,

with very numerous flowers in ‚ойе Flowers *05 in. in diam., reddish-brown; the 
bracts of the flowers in the lower part of the raceme ovate with long filiform tips much 
longer than the stalked ovaries, those of the upper part with much shorter tips and

lobe narrow, deeply cleft into two lanceolate parallel lobules separated by & deep 
sinus with a blunt apex. Clinandrium deeply and unequally toothed; lip of anther
