Europe, the seventh — G. pumilum — being recorded only from 
Brazil. G. hirsutum , the most primitive species in the genus, 
is represented in the Kew Herbarium, in the typical form, 
from the following places Franz Josef Archipelago, Europe, 
Mauritius, Java, Australia, New Zealand, Bermuda, United 
States. This species has four forms or varieties, only two of 
which — Walteri and americanum — occur in Europe, where 
both are very rare, whereas both are not uncommon in those 
distant parts of the world where the type-form is rare. Of 
the two remaining forms — leotioides and velutipes—\hQ former 
is confined to New Zealand and the latter to the United 
States, and in both these countries the type-form is again 
rare. The following diagram shows the distribution of the 
species of Geoglossum , the species being printed in clarendon
