From the specimens at hand Bulophia dentata appears to be a leafless species 
closely allied to Bulophia venosa Reichb. i

D. lunatum Lindl. in Journ. Linn. Soc. Bot. 3: 4. 
This is apparently a common species in the Philippine Islands where it is 
found growing on trees along the coast and inland. The flattened, erect stems, 
triangular distichous leaves and terminal inflorescence are quite characteristic. 
According to the field notes of collectors the small flowers are pale-yellow marked 
with purple. The lunate labellum and conspicuous callus serve to distinguish 
this species from its congeners in the Philippines. 
In Lindley’s Herbarium the Cuming plant, which I take to be the type of 
D. lunatum Lindl., appears to be conspecific with D. indiviswm. Lindley’s sketch 
of the flower agrees very well with the figure on Plate XIII of Presl’s “Reliquiae 
Haenkeanae,” although the general habit of the Cuming specimen is not exactly 
like that of the majority of the specimens recently collected in the Philippines.

Dendrobium platycaulon Rolfe in Kew Bull. (1892) 139. 
This species bloomed in the orchid collection of the Bureau of Science in 
November, 1909. According to notes which accompany the specimens submitted 
for identification the exact locality from which they were obtained and the name 
of the collector who discovered them are unknown. They certainly were Phil- 
ippine. As Mr. Rolfe states, this species resembles Dendrobium lamellatum. 
The pseudobulbs, however, are longer and narrower in relation to their length 
and the flowers are larger than in that species. In the notes which are appended 
to the original description of D. platycaulon the flowers are said to exceed an 
inch in length. In the specimens I have examined the flowers are scarcely an 
inch long, but in other details they agree very well with Mr. Rolfe’s description. 
D. platycaulon is a curious species with flattened pseudobulbs, which are about 
11 em long, 2.5 em wide and only a few millimeters thick; they are contracted 
into a slender terete base; the leaves are oblong-lanceolate, larger than the 
pseudobulbs and somewhat similar to them in outline. The specimens examined 
were apparently 3- or 4-leaved. The flowers are nearly white, and fragrant 
when fresh. They close in a short time and turn yellow. They are few in 
number and borne near the apex of the leafless pseudobulbs. 
Dendrobium scopa Lindl. Bot. Reg. (1842) Mise. 55. 
What I take to be specimens of this species have been received from Mr. W. 
S. Lyon who collected them in Tarlac Province. Mr. Lyon in his field notes 
describes the plants as terrestrial, growing among rocks. The flowers, which 
were open in June, were white, cinnamon-scented, the finely fringed lip being 
straw-yellow. The flowers are not showy but on account of the peculiarly 
fringed lip are of exceptional interest and very curious. The sepals and petals 
are similar, linear-oblong, about 15 mm long. The labellum is oblong, the apex
