An Enumeration of the. Plants Collected by H, H, Rusby, in 
Bolivia, 1885-1886.—II.

There has been a long delay in publishing this portion of the 
enumeration of Dr. Rusby’s collection, because at the time that 
the first comparisons were made at Kew in the summer of 1888, 
I felt that further study, and, in many cases, better material would 
be necessary in order to accurately determine many of the species. 
Furthermore, all of Mandon’s specimens, which were collected in 
the same localities which Dr. Rusby visited, such as La Paz and 
Sorata, were still lying in Schimper’s herbarium undescribed and 
bearing only manuscript names. 
In all instances when Dr. Rusby’s specimens agreed with 
Mandon’s the latter have been cited by number and locality, but 
as we did not possess at that time a set of Mandon’s mosses, and 
my time at Kew was limited, it was impossible for me to write de¬ 
scriptions of all of the new species preserved in Schimper’s her¬ 
barium collected by him. Hoping, however, that some one better 
fitted to do this than myself would have the opportunity of study¬ 
ing these Bolivian mosses, and also in recognition of the special 
privileges accorded to me at Kew while studying there, the first 
and most complete set of Dr. Rusby’s duplicates was deposited 
there. The second set was sent, after having been carefully 
studied and named as far as possible by one unacquainted with
