NO. 3 BRITISH EAST AFRICAN MOSSES DIXON 9 



bus 3-4 perangustis, incrassatis, limbiun bene notatmn, aliqiiando 

 rufescentenv, infenie evanescentem, instruentibus. Fructus ignotus. 



No. 3408b. Cliff base in thicket, western side of crater, alt. 13,500 

 ft. 



A very fine species, quite distinct in leaf form and structure, and 

 especially in the short nerve, from any of its allies. 



BARTRA^IIACEAE 



BARTRAMIA RUVENZORENSIS Broth. 



Tree heaths in crater, 13,000 ft.; No. 3422c. Bamboo heath zone, 

 10,000 ft., No. 3444, c. fr, 



BARTRAMIA STRICTULA C. M. 



Moorland, 14,000 ft.; No. 2391c, st. This seems to agree with 

 C. Aliiller's description of the above species. It is probably not dis- 

 tmct from the South African B. siibstricta Schimp. 



BREUTELIA STRICTICAULIS Dixon, Smiths. Misc. Coll. 692 : 21. 1918 

 Chff base in thicket, 13,500 ft.; No. 3408, st. 



BREUTELIA SUBGNAPHALEA (C. M.) Par. 



Chft" base in thicket, 13,500 ft.; No. 3415, c. fr. This agrees per- 

 fectly in the vegetative characters ; the seta is about i cm. long. C. 

 AKiller says only, " seta perbrevi," which would seem to apply ; the 

 seta in the Kew specimen of the original plant is perhaps slightly 

 shorter. 



The peristome, not described by C. ^Killer, is double, the outer 

 teeth well developed, red-brown, the inner fragmentary, pale orange- 

 brown. 



POLYTRICHACEAE 

 POLYTRICHUM PILIFERUM Schreb. 

 Polytrichiiin nano-globulus C. M., Flora, 71: 408. 1888. 

 Nos. 2391, 340/6, 3414; all c. fr. 



POLYTRICHUM HOEHNELII C. M. 



Nos. 3409, 3776 (Kew set) ; both c. fr. This species, while closely 

 allied to P. commune, seems really distinct in the marginal toothing of 

 the leaves and in their position when dry, more or less spirally con- 

 torted with the points rigidly spreading — " horride patentia."
