Dixon: NEW AND RARE AFRICAN MOSSES 69 
The differences from B. canariense and B. provinciale Philib. 
if not numerous are marked, and, I believe, constant. In these 
the leaf-margin is distinctly recurved, often all round, the nerve 
excurrent in a longish cuspidate point; the capsule lid is sharply 
acuminate, at times almost rostellate; here it is much lower and 
scarcely acute. B. polytrichoideum C. Miill. is described as having 
the leaves with recurved margins, obsoletely denticulate (here 
they are sharply toothed above), with the nerve longly excurrent. 
The nerve in the present species is excurrent in a very short, rather 
stout, often recurved mucronate point, entire or frequently 
denticulate. 
I have found a terminal male inflorescence on a fruiting stem, 
but it is possible this may not be the only position in which the 
antheridia occur, in view of the allied B. provinciale. 
POGONATUM SIMENSE (B. S. G.) Jaeg. 
Van Reenen, Transvaal, 1914, H. A. Wager 52. 
Another interesting extension of range, the species being 
hitherto known only from Abyssinia and the Cameroons. It 
agrees well with Schimper’s and Mitten’s ‘specimens at Kew. 
Bruch and Schimper describe the inflorescence as hermaphrodite. 
It appears to me rather paroicous than synoicous, the antheridia 
being apparently below the innermost perichaetial bracts. 
All the specimens show an occasional very faint rib on the 
capsule, which leads to a mild plication when dry and empty.

Mrs. Britton has kindly sent me a part of Mitten’s type, so 
that I have been able to establish the identity of Wager’s plant 
with the Lake Nyanza species. It is not recorded from any inter- 
mediate station, but I have a strong suspicion that E. M enyhardtit 
C. Miill. from the Zambesi will prove to be the same thing, and 
if so the geographical gap between the two would be materially 
bridged over. I have not seen E. Joannis-Meyeri C. Mill. from 
Kilimanjaro; Brotherus, who had specimens of both under his 
eye, I believe, keeps them separate, and one must suppose that
