Guam, Borneo and the Philippines.
There remain some doubts to refer the above materials to the nominal species.
With narrower segments and irregular false veinlets, our specimens accord well
with the Philippine plants of C. brevipes which is known to be much variable in its
size and accordingly in the construction of fronds. In the presence of the occasional
submarginal false veinlets and in the form of sari, especially in not so long tube,
our plants differ from C. megistostomum, from which, however, we can not distin­
guish C. brevipes sufficiently.
