Luzon, Province of Rizal, Mount Canumay, C. M. Weber 8, found 
on mossy trees, 700 m above sea-level. 
The affinity of this species seems to be with B. Cumingii Reichb. f. and 
with B. longiflorum Thouars. From the former it is readily Separated by 
the color of the flowers, the smooth margin of the dorsal sepal, and by 
the arms of the column. The column-arms are similar to those of B. 
longiflorum as shown in the figure of Cirrhopetalum Thouarsii in the 
“Botanical Magazine” plate 7214. The denticulate margin of the anthers 
is another distinguishing character in the comparison of B. Weberi and 
B. Cumingii. From B. longiflorum it is not so easy to distinguish B. 
Weberi. Here we have a striking similarity in the structure of the 
column, the erect wings and the denticulate anther-cap in both species. 
The plate formed by the union of the lateral sepals is rather more elliptic 
in B. Weberi than in B. longiflorum, and the leaves are broader in relation 
to their length. From the Cirrhopetalum Thouarsii of the Botanical 
Register (1838) t. 11 and of the Botanical Magazine, t. 4239, a plant 
which appears to be different from the C. Thouarsii of Bindley, B. Weberi 
is hardly distinct.
