imbricated, the perichaetial ones not chlorophyllous, with elongated, pro- 
senchymatous cells. In these respects, therefore, it must differ markedly 
from the present species, which has the leaves and perichaetial bracts all 
obtuse, the former usually widely rounded at apex, while the areolation of 
the perichaetial bracts does not differ materially from that of the other 
leaves. 
Hedwigiaceae. 
Hedivigidium erosuw. (C. M.) Par. Kaapsche Hoop, Transvaal, 1915 ; 
coll. H. A. W. (No. 304). This may, I think, be considered distinct 
from H. imherhe ; the leaf apex is often markedly erose-denticulate, though 
sometimes entire ; occasionally there is a short hair-point. The perichaetial 
leaves are erose above and subundulate at margin, distantly ciliolate-toothed 
half-way down. Is H. Macowanianum (C. M.) in any way different? 
Braunia Elliotii Broth. Hogsback, Tjumie, CP., 1917; coll. D. Hend. 
(No. 334). 
This plant agrees vegetatively exactly with the Central African species, 
and must certainly be referred there pending the discovery of fruit. 
PONTINALACEAE.

Neckekacbae. 
Filotricliella 'panduraefolia (C M.) Jaeg. (syn. P. Kuntzei C M.), 
Zwaartkop, 4500 ft.. Natal, 1916; coll. Sim (No. 8571). A form with 
densely fasciated branches and branchlets, which Mr. Sim says he has 
several times found. Uitenhage, CP., 1910 ; coll. W. Milne, comm Ingham 
(No. 5). Natal; from skin of otter in British Museum; comm. W. E. Sherrin. 
Crahamstown, CP., coll. J. Burton, comm. C Webster (No. 348). Evelyn 
Valley, Pirie Forest, 4500 ft., CP., 1892 ; coll. Sim (No. 7018), c. fr. This 
last is the plant described by C Mueller as P. Kuntzei ; Mr. Sim writes that 
he was with 0. Kuntze in the Pirie Forest when he collected it, and remembers 
the moss attracting Kuntze's attention. C Mueller describes it as being 
pale in colour, and that, indeed, is the only difference to be detected between 
it and P. j^anduraefolia.
