1915; coll. R. E. Symons, comm. Sim (No. 8245), c. fr. ; Kaapsche Hoop, 
Transvaal, 1915 ; coll. H. A. W. (No. 312), c. fr. 
Polytrichum trichodes C. M. Near Hogsback, 4-6000 ft., Tjumie, CP., 
1916; coll. Hend. (No. 233). 
Polytrichum comimme L. I have received this from several stations in 
Cape Prov. and Natal. Specimens from Greorge, 1916, coll. H. A. W. 
(No. 539), and Dohne Hill, CP., 1898, coll. Sim (No. 7200), both c. fr., 
I should refer to var, minus Weis. A remarkably branched, fastigiate 
form from Grilletts, on clay bank on roadside. Natal, Oct., 1916, coll. Sim 
(No. 8542), is the \Sii\ fastigiatum Wils. ; Mr. Sim writes that it is probably 
this which Dr. Shaw took to be Polytrichum dendroides Hedw., and which 
he states is in the herbarium at Kew from S. Africa. 
Erpodiace^. 
Erpodium transvaaliense Broth. & Wag. sp. nov. (PI. XII, fig. 13.) Ab 
E. Holstii Broth., cui proxima, differt tantum foliis magis hyalino-ainculatisy 
perichaetialibus inaecipue apicem versus distincte incanis, in pilum plus 
minusve elongatum basi explanatum hyalinum integrum angustatis ; atque 
cellulis folii magis isodiametricis, raro transverse elongatis. 
Hab.—Wolhuter ; coll. H. A. W. (No. 189). 
I have not been able to see an authentic specimen of E. Holstii Broth., 
but a plant from Mt. Meru, Cerman East Africa, which I take to be that 
species, differs only very slightly from the Wolhuter plant in the leaves 
scarcely hyaline-pointed, the perichaetial leaves having a short half-twisted 
apiculus usually brownish rather than hyaline. The cells in that are 
very regularly seriate, for the most part transversely elongate, while in 
E. transvaaliense they are usually isodiametric. The walls in both are thin, 
very slightly collenchymatous at the angles, but in the upper part of the 
leaves when hyaline, or under pressure or slight injury, they very readily — 
as is natural with large cells of delicate structure — collapse, and then have 
the false appearance of being widened and incrassate. 
E. Poheguini Par. & Broth, has rather smaller cells, with the walls 
more thickened. 
E. distichumW^g. & Dix. sp. nov. (PI. XII, fig. 14.) E. grossireti C. M. 
proxima ; differt foliis omnibus obtusis, nullo modo apiculatis, perichaetialibus 
chloropliyllosis, areolatione ei foliorum verorum simillima ; caules ramique 
prostrati, foliis subdistiche patentihus, siccitate erectis, conniventibus. Theca 
emergens. 
iia5.— Barberton, Transvaal, 1914-15 ; coll. H. A. W. (No. 279) ; 
Maritzburg, 1915 ; coll. H. A. W. (No. 226). 
E. grossirete C. M. is described as having the leaves at times apiculate.
