New and Interesting South African Mosses. 
205- 
Bartramiaceae. 
Bartramia. Several of the S, African species of this genus, notably 
the gymnostomous species of § Strictidium and some of the § Vaginella, 
present considerable difficulties and consequently involved synonymy, which 
at present I have not been able to clear up to my satisfaction. I am inclined 
to think that one or two of the species are exceedingly variable, and that this 
has led to an undue multiplication of names. I hope before long to be able 
to elucidate some at least of these obscurities. One reduction I can make with 
certainty. B. afro-stricta. C. M. is entirely identical with B. substricta 
Schinip., as a comparison of Eehm. M. Austr.-Afr. 203, 204, 205, with 
Schimper's type at Kew shows. 
I have received this species from Table Mt. and from Camps Bay, CP., 
coll. H. A. W. (No. 597). 
Fhilonotis androgijna (Hampe) Jaeg. Knysna; and Ceorge, CP.,. 
1916 ; coll. H. A. W. (Nos. 526, 537), c. fr. Slightly more compact and 
shorter than Hampers original plant, but inflorescence and general structure 
the same. 
P. laxissima (C M.) Bry. Jav. Albert Falls, "JSTatal, 2000 ft., 1917 ; coll. 
Sim (ISTo. 8704). Near Hogsback, 4-6000 ft., Tjumie, CP., 1916; coll. Hend. 
(No. 186). The latter plant at least is P. curvifolia Besch. ; but that and 
probably P. tenuicula (Hampe) Besch. are scarcely more than forms of 
P. laxissima (C. M.) Bry. Jav. ; cf. Cardot, ' Mousses de Madagascar,' 
pp. 308 sqq.* 
P. delagoae (C M.) Broth. George, Cl^., 1916; coll. H. A. W. 
(No. 5000), c. fr. I have determined this from the description (of the 
sterile plant). C Mueller described his species as with the margin " ubique 
erecto,"' but Brotherus places it in a section having recurved margin; 
Prof. Wager's plant has it recurved. The peristome is double, inner 
reddish below, processes imperfect, shorter than the outer teeth, smooth or 
nearly so. 
P. mauritiana Aongstr. Hogsback, 4-6000 ft., Tjumie, CP., Jan., 1916 ; 
coll. Hend. (No. 193), and again, 1917, coll. D. Hend. (No. 353). Cardot 
refers P. luteo-viridis Besch. to this species. 
P. hymenodon (C. M.) Jaeg. Caika's Kop, 6000 ft., Tjumie, CP., 1916 ; 
coll. Hend. (No. 228). Agrees quite well in structure with Eehm. M. 
Austr.-Afr. 186, but is much taller and more robust, 5-6 cm. high and of 
Philonotoid habit. 
P. afro-fontana (C. M.) Par. (Syn. P. oraniae Eehm.). Wet bank of 
stream, Pretoria, 1910 ; coll. H. A. W. (No. 2) ; Estcourt, 4600 ft., 1913 ; 
* I have this species from Joseph's "Well, Maturieh, near Cairo, 1911, coll. Miss 
Armitage (det. Dismier), and also from El Marg-, Cairo, on damp ground near water,. 
April, 1910 ; coll. D. C. Eady.
