NO. 3 BRITISH EAST AFRICAN MOSSES — DIXON I7 



of a slightly different habit ; but I can find no structural dift'erences, 

 and I am strongly disposed to consider it only a slight form of the 

 same thing. 



II. A SMALL COLLECTION OF MOSSES FROM THE ABERDARE 



MOUNTAINS 



The mosses in the following list were collected near IMount Kenia 

 by Mr. A. Y. Allan in 1910, and were sent me for determination 

 by Rev. D. Lillie. Although the collection is small it is of unusual 

 interest, containing as it does the type of a new genus. 



CAMPYLOPODIUM EUPHOROCLADUM (C. M.) Besch. 



Nos. 395b, 398. This species has not previously been found in 

 xA.frica. It is known otherwise from Java, Tahiti, New Caledonia, 

 New Zealand. The second specimen above cited has very young 

 fruit and old setae. 



[Campylopodiitm khasiannm (j\Iitt.), a very closely allied species, 

 indeed doubtfully distinct, differs in its fruit only, so far as I have 

 been able to observe ; the vegetative characters described by Mitten do 

 not appear to hold good. There is the possibility, therefore, that the 

 African plant may belong there ; but C. cuphorocladum being a plant 

 of much wider distribution (and not improbably including C. khasia- 

 nnm) I have thought it best to refer this plant to the former.] 



DICRANUM JOHNSTONI Mitt. 



Dicranum Stuhlmannii Broth. Bot. Jahrb. Engler 20: 177. 1894. 



No. 400, c. fr. I have compared this with the original of D. 

 Johnstoni (KiHmanjaro, H. H. Johnston 52), and it agrees perfectly. 

 It is also identical with D. Stuhlmannii (Stuhlmann 3290b, and 

 J'olkens 1 166, det. Brotherus). Mitten's description of the leaves 

 of his species as " linearia, sensim loriformi-angustata," and " unlike 

 any form of D. scoparium from the narrow^er lower portions of the 

 leaf," is very misleading, and is no doubt the cause of Brotherus 

 having redescribed the plant. As a matter of fact, in Johnston's 

 specimen the leaves, though occasionally (abnormally) narrow at 

 the base, are usually dilated there quite as in D. Stuhhnannii and 

 other species. 



The fruit has not hitherto been described. Perichaetium about 

 6 mm. long, tubular, the bracts convolute with spreading points ; 

 seta about 2 cm. long ; capsule erect, symmetrical, cylindric, with very
