clinandrium erose, РоПіша 8, unequal, one set of four much longer than the other set, 
all attached to a singie membrane.

The sepals and petals are of a pale grcenish-brown colour, with dark brown nerves, 
the lip is white with small pink spots and a large blotch of pink at the apex. The 
lip has also а yellow bloteh at the base, the mentum and column are yellow. The 
pseudo-bulbs and leaves are of a uniform green colour.

Pseudo-bulbs 1 to 1:5 in. long, arranged in a chain, ovoid-cylindric, with large 
membranous sheaths when young, each bearing at the apex a broadly ovate-lanceolate, 
5- or 6-nerved, rather thick blade deeply cordate at the base; length 3 to 4 in., breadth 
1°75 to 95 in., petiole “5 to 1 in. Scape from the base of the pseudo-bulb, sheathed, 
3 or 4 in. long, bearing at its apex a few-flowered short raceme. Flowers "65 to "Тӛ in. 
long; floral bract ovate-lanceolate, shorter than the shortly stalked ovary. Sepals and 
petals sub-equal, linear-oblong, acute, reflexed on the ovary. Jip almost flat, adpressed 
to the column, broadly oblong, without lobes, the apex broad and emarginate, the edges 
minutely crenulate; the upper surface with a broad thickened pubescent mesial band 
passing near the apex into 3 toothed ridges, the entrance to the bilobed spur at the 
base clothed with long hairs. Column without a foot, its sides narrowly winged from 
base to apex, the wings crenulate opposite the stigma. Anther short, broad and with 
two short horns. Pollinia 8, very unequal, the four smaller only one third of the size 
of the four larger.

The pseudo-bulbs and under surfaces of the leaves are purple, while the upper 
surfaces have a metallic lustre and are green, flushed and mottled with purple; the 
sepals, petals, ovary and (in part also) the base of the lip are red, the anterior portion 
of the lip and its spur being yellow. The typical form of this is found in the 
Malayan countries. As described and figured by Blume (Orch. Archipel. Ind. 171, t. 61; 
p. 1) its pseudo-bulbs are quite cylindrie, not having bulbous bases as in the variety 
Sikkimensis. The flowers are also paler in colour and slightly larger iu size. The 
synonymy of the typical form is as follows:—N. pulchrum, Blume Bijdr. 372, t. 32;
