NEW OR NOTEWORTHY ORCHIDS 
Bulbophyllum Levanae Ames Orch. 5 (1915) 178. 
In recent studies of Philippine orchids it has become 
apparent that B. nyrnphopolitanum Kranzl. and B. trigonose- 
palum Kranzl. are near allies of B. Levanae, and sufficiently 
close to it to arouse suspicion that they represent the same 
species. Dr. Kranzlin kindly loaned to me the types of 
B. nijmphopoUlanum and B. irigonosepalum. These consist 
of specimens obtained in the Philippine Islands by A. Loher. 
B. nymphopolilanum is referred doubtfully to the Philippines 
in the original description published in 1916, but I think 
there can be only slight doubt as to its origin, as it is a close 
match for ZI. Levanae from Leyte, differing from it chiefly in 
having somewhat larger flowers. B. Irigonosepalum is char¬ 
acterized by having larger flowers than either B. Levanae 
or B. nymphopolilanum, but structurally is very similar to 
them. In all of the specimens examined the labellum pos¬ 
sesses the peculiar oblong, lobe-like appendages which are 
not found in any other species of the genus heretofore re¬ 
ported from the Philippines. These appendages of the 
labellum are basally situated near the point of insertion on 
the foot of the column. B. nymphopolilanum, — if my con¬ 
clusions arc justified, — should be referred ioB. Levanae. As 
for B. Irigonosepalum, it may prove to deserve a similar fate, 
but until more material than I have been able to secure has 
been examined it may be well to regard it as a close ally 
of B. Levanae, perhaps as a variety of that species.

Bulbophyllum syllectum Kranzl. in Pedde Repert. 17 
(1921) 383. 
In habit and flower-structure B. luzonense and B. 
sylleclum are so similar that I have been unable to find satis¬ 
factory distinguishing characters that will separate them 
clearly. B. sylleclum was described from specimens col¬ 
lected in the Philippines by A. Loher. The type consists of 
specimens that were cultivated in the botanic garden at 
Mnnehen-Nymphenburg.
