Oss. I have enumerated the above as species merely because 
they are given as such by the authors of the ‘ Hortus Kewensis ; 
for, from the examination of numerous specimens from many 
different countries, we find it quite impossible to point out any 
character whereby to distinguish them. Exclusive of C. bulbvfera, 
the whole appear to be merely different forms of C. fragilis.
