600 Gr. King & R. Pantling. — New Indo-Malayan Orchids. [No. 3, 



together in the upper part of the stem, lanceolate to ovate-lanceolate, 

 acute or subacute, the bases rounded, petiole *5 to '65 in. long, expand- 

 ing into a short broad lax sheath at the base; length J 75 to 3 in., 

 breadth '7 to 12 in. Peduncle three times as long as the stem, slender, 

 bearing 3 or 4 distant lanceolate bracts ; spike 2 to 3 in. long, the 

 flowers numerous, after expansion rather distant, '2 in. across ; floral 

 bract lanceolate, acuminate, as long as the pubesceut ovary. Sepals 

 subequal, broadly triangular, acute. Petals as long as the sepals, broadly 

 triangular, falcate, acute. Lip longer than the sepals and petals 

 cymbiformly saccate in its lower half, the sac containing on each side 

 three retroflexed short cylindric pointed processes ; the anterior part 

 with two horizontally divergent oblong lobes with truncate erose apices ; 

 the upper surface smooth in the living state. Column short, broad, the 

 apex acuminate ; its front with two vertical plates nearly touching by 

 their margins, and a second and smaller pair situated obliquely at their 

 bases. Stigmas 2, elliptic and somewhat oblique. 



S. Andaman ; at Dhani Kheri : G. King. 



A species near Z. moulmeinensis, Hook, iil., but having smaller 

 flowers, differently shaped sepals and petals, and three calli instead of a 

 siugle callus on the interior of the lip on each side. In the living state 

 the lip is glabrous ; but when dry it has the appearance of being puberu- 

 lous, from the contraction of some of the epidermal cells. 



OPHRYDEiE. 



Orchis sub-rotunda, n. spec. Height of entire plant 7 to 9 in. ; 

 tuber oblong, entire, hairy. Leaf radical, solitary, sub-coriaceous, elliptic- 

 ovate to sub-rotund, blunt or subacute ; the base rounded, not narrowed 

 but abruptly joining the short scarious tubular sheath ; length 4 in., 

 breadth 3 to 4 in. Peduncle 3 to 45 in. long, smooth, bearing at distant 

 intervals 2 or 3 linear-lanceolate acuminate bracts '5 to "75 in. long. 

 Raceme 3 to 4 in. long, bearing many but not crowded purple flowers each 

 measuring about *5 in. across ; floral bract ovate-lanceolate, acuminate, as 

 long as the straight smooth ovary. Dorsal sepal broadly ovate, conniving 

 with the petals to form a hood over the column, all ciliolate ; lateral pair 

 inserted partly on the spur, broadly-elliptic, falcate, subacute, reflexed. 

 Petals elliptic with broad bases, subfalcate, subacute, nearly as long 

 as the dorsal sepal. Lip orbicular, a little longer than the sepals, slightly 

 narrowed at the base, the margins undulate, the upper surface densely 

 and shortly hispid especially towards the middle, the base with 2 very 

 short parallel thickened smooth ridges just above its junction with the 

 foot of the column ; spur subcylindric, nearly straight, parallel with 

 but less than half as long as the ovary, as long as the reflexed lateral
