There are two distinct Mosses named F. crispans in Schimper’s 
Herbarium. One is described above as F. aequalis ; the other, from 
the Cape of Good Hope, is barren, and I have not been able to 
identify it. It is evidently closely allied to F. aequalis , but has 
a narrower limb. The Guatemala plant (F. aequalis) has ‘Hooker 
174’ on Schimpers label; this is probably a memorandum note, and 
is not the name of the collector, as Sir Joseph Hooker never visited 
Guatemala.
