In the Enumeratio Plantarum f[ormosanarum, I referred 
this plant to C. excavata, thinking that it might be a small form of 
that species, On examining a set of several specimens collected 
in different parts of the island, I have, however, found that the 
plant is always of the same constant form, and is quite different 
from the type of the named species in many points but especially 
in its leaves which are in the latter species very much larger, 
attaining the size of even 3-4 times those of the Formosan plant.
