coriaceous, 10-20 mim. long, 8-5 mm. broad ; inflorescence 
1-flowered, from the top or near the top of the pseudo- 
bulb, consisting of a flower a short pedicel and a bract 
which surrounds the pedicel; flowers small, white, 5-6

about 2.5 mm. long and 2 mm. broad; lateral sepals at- 
tached to the column-foot, extended into a short mentum 
at the base, blade broadly ovate, about 8 mm. long and 
2.5 mm. broad: petals linear-oblong, acutish, 1-nerved, 
about 8 mm. long and 0.7-0.8 mm. broad: lip oblong 
in outline, 8-lobed, about 4.5 mm. long and 2mm. broad, 
the lateral lobes small, very thin and inconspicuous, — 
the middle lobe bilobed and thickened; column, includ-

Dendrobium microphyton is a most distinct species 
with no close allies among the Philippine species of Den- 
drobium. It is apparently closely allied to Dendrobium 
funiforme Blume, a rare species known, according to 
published records, only from New Guinea. Dendrobium 
Juniforme is known to me only from the descriptions and 
from Blume’s figures (Rumphia 4 (1848) t. 198, 4, t.1. 
1981). The present species differs from D. fruniforme in 
having a 8-lobed oblong lip, not an entire lanceolate one ; 
it also seems to have a shorter mentum. Other differ- 
ences in the petals and sepals are noticeable, as well as 
minor differences in the vegetative structure.
