New and Interesting South African Mosses.

are single. The basal cells in P. suhcrispatum are wider towards the margin, 
and subquadrate ; here they are all narrow, only a single row of marginal 
cells being rather wider and pellucid. 
Since the publication of this species by Theriot & P. de la Varde, I have 
received two plants, coll. H. A. W., which must certainly also be referred 
there, viz. Goodoo Pass, Drakensberg, Natal, 1918 (No. 714), and Ladysmith, 
1918 (ISTo. 681), both c. fr. The original gathering was from Van Eeenen, 
ISTatal. 
Grimmia apocarpa (L.) Hedw. Hogsback, Tjumie, CP., 1917 ; coll. 
D. Hend. (No. 356), c. fr. ; and near Hogsback, Tjumie, 4-6000 ft., 1916 ; 
coll. Hend. (No. 210), c. fr. An elongate form with rigid stems and 
leaves and very short hair-points. The leaf apex is very commonly 
orange-brown. This decoloration occurs on leaves at all parts of the stem 
and does not appear to be due to temporary conditions. The leaves are 
widely spreading when moist and the habit is somewhat that of G. rivularis ; 
but there appears to be no central strand, and a short and inconspicuous 
hair-point is often present. 
G. commutata Huebn. Dohne Hill, CP., 5000 ft., 1898 ; coll. Sim 
(No. 7218), c. fr. Prof. Wager gives it also from " Eydal Mt." in his 
' Check-list of the Mosses of S. Africa.' 
G. pulvinata var. ohtusa Brid. Probably frequent. G. Ecldoni Sprengel 
is certainly the same thing. 
JRhacomitrium austro-patens (C M.) Broth. Caika's Kop, 6000 ft., 
Tjumie, CP., 1916 ; coll. Hend. (No. 240), c. fr. One or two old and 
imperfect capsules are present and a single immature one ; these show a 
very short, straight seta, only a few millimetres long, and a small, elliptic 
capsule. 
B. sympliyodontum (C M.) Par.''^ Giant's Castle, 8000 ft.. Natal, 1915 ; 
coll. P. E. Symons, comm. Sim (No. 8697). I cannot separate this in any 
way from the widely distributed Australasian and subantarctic species 
except that the nerve is very slightly narrower than is usual, but this can 
be quite matched by specimens I have of that plant. The distribution of the 
species is quite in favour of the identification, as it is recorded from Pata- 
gonia, Fuegia, Falklands, New Zealand and Tasmania, and I have it also 
from Victoria, Australia, and also from the New Hebrides. 
Orthoteichaceae. 
Diplostichum Mont. {Syn. Eustichia [Brid.] Mitt.). 
On the nomenclature of this genus see the important note by Cardot, 
' Mousses de Madagascar,' p. 226. 
? Diplosticlium longirostre (Brid.) Card. Bushman's River, Natal, 
* Rhacomitrium crispulum Hf . & W. appears to be the more correct name for this.
