The present species was first described by Hampe in his 
‘ Prodromus Florae Novo-Granatensis ’ ( 5 ) in 1865. In the 
diagnosis here given the leaves are described as { marginata.’ 
In 1869 Mitten in his ‘ Musci austro-americani ’ ( 14 ), in 
treating of the genus Streptopogon , kept up Hampers species, 
of which specimens were not seen, and described as new 
species A. latifolius and A. setiferus. In Mitten’s key to the 
species of the genus the three plants are thus distinguished : 
Folia limbo marginata. 
Folia latiora minus acuminata, -S'. Lindigii. 
Folio oblongo-ovalia, S. latifolius. 
Folia immarginata. 
Folia elliptico-spathulata, A. setiferus. 
First, as regards 5 . setiferus , Mitt. This is in all respects 
identical with A. Lindigii , Hampe, as a comparison of the 
types in Mitten’s and Hampe’s herbaria shows. If Hampe’s 
and Mitten’s diagnoses are compared it will be found that, 
except for the fact that Hampe describes the leaves as 
c marginata,’ while Mitten says c limbo nullo,’ no distinguishing 
characters are given. Now, as mentioned below more fully, 
the marginal cells of A. Lindigii are scarcely or not at all 
different from those of the rest of the leaf, and never form 
a true ‘ limb,’ as e. g. is found in the leaves of A. erytliro- 
dontus , which, it may be noted, Hampe ( 1 . c.) describes 
also as simply ‘ marginata.’ 
A. latifolius] Mitt., was stated to differ as follows : ‘ Statura
