CYRTANDRACEAE NOVAE PHILIPPINENSES, I 
By F. Keanzlin 
(Berlin, Germany) 
The collections of Cyrtandraceous plants, made for the Bu- 
reau of Science, for several years past have been communicated 
from time to time to the Kgl. Botanisches Museum at Berlin, 
and the entire collection has been submitted to me for deter- 
mination. 
The number of new species of Cyrtandra is remarkable. All 
botanists who have worked on this interesting and difficult family 
are aware of the fact that the geographic range of the great 
majority of the species is very limited, and that even in the 
same range of mountains each valley may have its own peculiar 
forms or even species. The great number of species, their 
origin, and their restricted ranges are puzzling facts and the 
rapidly increasing number of known species in the genus is, 
in respect to classification, somewhat disagreeable and trouble- 
some. Will Cyrtandra become a great genus like Ficus or Den- 
drobium? In 1883, C. B. Clarke admitted 167 species, and if we 
cannot double this number to-day we are certainly not far from it. 
As in Ficus and Dendrobium, so in Cyrtandra, those species dis- 
tinguishable only by slight characters greatly predominate over 
those that are sharply defined. With the recent discovery of so 
many species in the more accessible parts of the Malayan region, 
what a boundless number of species we may expect from the 
future botanical exploration of the interior of Borneo and of New 
Guinea! For the present the "Conspectus generum" as estab- 
lished by the late C. B. Clarke can and should be maintained, and 
it is to be hoped that it will prove to be serviceable for a much 
longer time in the future. The comparatively "large number of 
species proposed in this paper were rather easily arranged and 
distributed according to the outline of classification constructed 
by Mr. Clarke.
