inhabits damp woods, where it grows on and through the damp 
woods like an Anectochilus. Itis very impatient of cultivation.

What is evidently this species was referred by Sir Joseph 
Hooker to M. plantaginea, Steud. (Pterochilus plantagineus, 
Hook. and Arn.), a native of the Society Islands, from which I 
believe this plant to be quite distinct. The foliage and stem 
are very similar in the two; but in M. perakensis the bracts 
are twice as long, the sepals shorter, the lip, instead of being 
nearly quadrate, is almost three-lobed. The auricles are very 
large, longer than the dorsal sepal; and, between them and 
the dentate mid-lobe, is a distinct notch. The mid-lobe is quite 
short, with six in-curved processes. In M. plantaginea, Steud., 
the lip is oblong, squared in outline, there being no distinction 
of the mid-lobe; the teeth are shorter, more equal, more 
numerous, and straight; and the fovea oval-rounded. 
Crepidium Rheedii, Blume, also referred to M. plantaginea, 
Steud., is I believe a totally different plant, with much smaller 
flowers. Ihave received it from Java. Lindley’s M. Rheedw 
consisted of a mixture of Epidendrum resupinatum, Forst. f. (1.e-, 
M. plantagineus, Steud.), Malaxis Rheedii, Willd. (syn. Micro- 
stylis Eheedii, Wight), a native of India; and Crepidiwm
