New and Interesting South African Mosses. 
195 
T. eruhescens (C. M.) Broth. Zoutpansberg District, North Transvaal,. 
1910 ; coll. T. Jenkins, comm. W. Ingham. Upper Bushman Eiver, 6000 ft., 
Natal, 1905; coll. Sim (No. 8669). 
I have elsewhere (Smithson. Miscell. Colls. 69, 2, p. 14) given my opinion 
that Barbula oranica CM., and B. exesa C. M. are inseparable from the 
tropical and subtropical species described by C. Mueller as B. erubescens. 
T. erythroneura (Schimp.) Broth. Cape of Good Hope, 1912 ; coll. S. W.. 
Hall. This agrees well with Schimper's specimen, coll. Wilms, at Kew. But 
is it anything more than a ruralis form ? 
T.prince;ps De Not. Near Cape Town, 1915 ; coll. H. A. W. (No. 350), 
c. fr. A synoicous plant, which I cannot separate in any way from this 
almost cosmopolitan species. 
T. hrachyaechme (C. M.) Broth. Hout Bay, CP., 1916 ; coll. H. A. W. 
(No. 604), c. fr. ; Hogsback, Tjumie, CP., 1917; coll. D. Hend. (No. 325). 
This latter plant shows abundant comal propagula foliose in form, and 
often developing in situ into short leafy stems. Prof. Wager's plant has 
exceedingly small and short capsules, but I am unable to say to what extent 
this is due to depauperation. 
Brotherus, as also Paris, writes the specific name hrachyacme ; C. Mueller 
as hrachyaichme. The derivation is clearly from al^iur], the correct trans- 
literation of which would be -aechme. 
T. Euhryum (C. M.) Dixon. Eietfontein, Transvaal, 191 6 ; coll. H. A. W. 
(No. 243). See also my note in ' Bull. Torr. Bot. Club,' 43, 66. 
Tortula trachyneura Dixon, sp. nov, (PI. XI, fig. 7.) 
Dioica videtur; flos femineus tantum visus. T. rurali proxima ; differt 
costa supra dorso alte grosso sparse scahra. Folia obtusissima, marginibus 
jperanguste hie illic refiexis, costa in aristam longam hyalinam dentatam 
excurrens ; cellulae superiores majusculae, 10-14 /x latae, sat distinctae. 
m^.— Tjumie, CP., 1917 ; coll. D. Hend. (No. 330). 
This may possibly belong to T. ruralis, but the roughness at the back of 
the nerve is different from anything I have seen in that species. There it 
may be quite smooth or markedly but finely muriculate ; here it is coarsely 
and sparsely papillose or almost hispidulose. None of the other Southi 
African species show this character of nerve. 
Encalypta ciliata Hoft'm. Wittebergen, Herschel, 8-9000 ft., CP., 1917 ; 
coll, 1. Hepburn, comm. Sim (No. 8706), c. fr. 
G-RIMMIACEAE. 
Glyphomitrium crispatum (Hook. & Grev.) Broth. Table Mt., 1910; 
Cape Town, 1915; coll. H. A. W. (Nos. 31, 356). c. fr.; Van Eeenen, 1914; 
coll. H. A. W. (No. 83), c. fr.; Platte Klip, near Cape Town, 1906; coll.. 
H. Nicholson, c. fr.
