New and Interesting South African Mosses. 203 
Bescherelle may be assumed to have known the species of Bory. Yegeta- 
tively the S. African plants agree exactly with, e.g., de I'lsle's specimens. 
The fruiting characters, as far as I have examined them, also agree, though 
the seta and capsule in Duisabo's specimen — the only one in good fruiting 
condition — are slightly longer than in the general run of the S. African 
plants. 
There is no reason, of course, why the species should not be common to 
Eeunion and the African continent ; indeed, the more doubtful question is 
whether there is any true specific distinction between this and some of the 
other southern plants of this group, e. g. the Australasian B. leptothecium 
TayL, and the S. American B. Lechleri Schimp— whether in fact it is not one 
widely distributed species ranging over the whole subantarctic region. As 
to this, however, I do not venture an opinion. 
It may be helpful to give in the form of a key some of the salient 
distinguishing characters of the four S. African species of this group. 
B. polytrichoideum CM. is a much smaller plant with quite different leaf, 
.and appears to me to belong not here but to group Trichophora.
