cealed by imbricating loose distichous leaf-bearing 
sheaths, sometimes once forking near the base with sub- 
parallel branches. Leaves numerous, distichous, spread- 
ing-ascending, oblong or elliptic-oblong, often up to 
3.7 cm. long and 7 mm. wide, sessile. Inflorescences soli- 
tary in the upper (but not uppermost) axils, strict, with 
very short peduncles and long-exserted pedicellate ova- 
ries. Flowers small. Dorsal sepal ovate-oblong, abruptly 
acute or apiculate at the rounded apex, about 9.2 mm. 
long and 4.2 mm. wide. Lateral sepals similar, oblique, 
complicate-acute and apiculate, very slightly shorter and 
narrower than the dorsal sepal. Petals broadly oblong or 
obovate-oblong (rather than ‘‘ovate’’), obtuse, shorter 
than the sepals but equally wide. Lip obovate-oblong in 
outline, constricted on each side (i.e. lobulate), rounded- 
truncate and lightly retuse in front, rounded-cuneate be- 
low, about 7 mm. long and 4.4 mm. wide near the mid- 
dle; callus on the disc sometimes obscure. Column about 
2.8 mm. long at the back, with a very short foot.

H. G. Reichenbach states (in Walpers Ann. 6 (1863) 
540) that he had carefully inspected the type of Isochilus 
grandiflorus, and, as a result, he referred this concept to 
the synonymy of Mawillaria luteorubra Reichb. f. (Cam- 
aridium luteo-rubrum Lindl. ). 
Judging by the original description and a pen drawing 
of the flower of Isochilus grandiflorus trom the Lindley 
Herbarium, I cannot subscribe to this treatment. Jso- 
chilus grandiflorus differs from Camaridium luteo-rubrum,
