tuberous. Stem up to the raceme 7-10 em. high, entirely 
or mostly invested by the leaves, at base provided only 
with sheaths. Leaves four or five, distichous, mostly im- 
bricating, apparently convolute or conduplicate, ovate, 
ovate-lanceolate or lanceolate-elliptic, up to 4.5 em. long 
and about 1.8 cm. wide (the upper and lower blades often 
smaller), acute or acuminate, erect-spreading. Raceme 
up to 10.5 em. long and about 8 cm. in diameter, densely 
flowered (at least above). Floral bracts lanceolate, long- 
acuminate, up to 8.2 cm. long. Flowers yellowish green. 
Sepals minutely crenulate near the apical margins. Dorsal 
sepal broadly ovate, cucullate, concave, 7.5-8 mm. long, 
about 5.8 mm. wide, obtuse or acute, 8- to 5-nerved, 
prominently carinate near the base on the outer surface. 
Lateral sepals obliquely ovate-lanceolate, 9 mm. long, 
about 3.7 mm. wide, reflexed, acute or obtuse, subapically 
mucronate on the back, 3- to 4-nerved. Petals bipartite ; 
posterior lobe much the larger, lanceolate-oblong, about 
7 mm. long and 2 mm. wide, obliquely obtuse or acute, 
2-nerved; anterior lobe shorter, linear, incurved and over- 
lapping the posterior lobe, about 5.4 mm. long, obtuse, 
1-nerved. Lip tripartite near the base, parallel to the re- 
flexed lateral sepals, 9-9.5 mm. long; lateral lobes shorter 
than the mid-lobe, filiform, 6.4-7 mm. long, parallel to 
the mid-lobe or diverging, obtuse, slightly incurved at 
the apex, 1l-nerved; mid-lobe linear-ligulate, about 7.5 
mm. long and up to 1.75 mm. wide, obtuse, longitudi- 
nally convex, 8-nerved. Spur longer than the lip, clavate, 
about 1.4 em. long, obtuse, more or less curved near the 
apex. Anther canals and stigmatic processes short, thick. 
Habenaria pumiloides is allied to H. pumila Poepp. & 
Endl., but differs in having shorter broader leaves and 
much larger flowers. It varies from H. Ernsti Schitr. 
in having a dense raceme of much larger flowers, in hav- 
ing a longer anterior lobe of the petals, in having a dissim-
