The denticulate middle lobe suffices to distinguish this from the pre- 
ceding species. Also the long cylindric spur is characteristic.

Taeniophyllum Copelandii is a copiously rooting species, the roots form- 
ing a dense mat on the bark of trees. The scapes, several arising from 
each plant, are very short and from dried material appear to bear at most 
two, inconspicuous, white flowers, which persist on the elongated fusiform 
capsules. The sepals are free for the most part, the upper one appearing 
to be lightly adherent to the petals. The labellum is simple, strongly sac- 
cate, and in front produced into a lanceolate plate near the end of which 
is a minute callus which in dried specimens appears to have been cucullate, 
with its sides slightly decurrent on the disc of the labellum.
