NEW OR NOTEWORTHY ORCHIDS 
Floral bracts lanceolate, acuminate. Lateral sepals falcate- 
semiovate, about 7 mm. long, reflexed, 3-nerved. Dorsal 
sepal round-ovate, strongly cucullate, 5-5.4 mm. long when 
expanded, broadly obtuse, truncate or shallowly retuse at 
the slightly recurved apex, 3-nerved. Petals deeply bilobed 
with the divisions at right angles; posterior lobe larger, ob¬ 
long or spatulate-oblong, 4.2-4.9 mm. long, more or less 
falcate, often oblique at the apex; anterior lobe much smaller, 
linear-triangular, 2-2.4 mm. long. Labellum linear with a 
sharp spreading triangular tooth on each side at the base 
(as in H. alaia Hook.), about 9.2 mm. long in natural posi¬ 
tion, sharply geniculate-reflexed about 3 mm. from the base, 
obtuse or abruptly acute, very fleshy. Spur slender, cylin- 
dric, slightly dilated near the apex, 1.9-2.9 cm. long. 
This description was drawn from dried material in an 
advanced stage of development, and all the flowers show 
mature ovaries and somewhat withered perianth parts. 
Habenaria aviculoides appears to be closely allied to 
H. avicula Schltr., but it differs from that plant in having 
truly bipartite petals and a geniculate lip.
