DICRANACEAE 

 DISTICHIUM KILIMANDJARICUM C. M. 



Loc. 3,630 meters, No. 1547. I have no doubt that this is C. 

 Miiller's species, of which I have not seen specimens. The only- 

 slight discrepancy is that C. Miiller describes the subula as papillose 

 near the apex, while in this the greater part of the fine filiform 

 subula is roughened ; finely and regularly tuberculate would perhaps 

 describe it best. The stems are exceedingly delicate and slender, 

 the leaves distant, with a very long filiform subula which is very 

 flexuose and curled when dry. 



BLINDIA ACUTA (Huds.) Bry. eur., forma PROLIXA 



Loc. 3,630 meters, No. 1593b. Accompanying Rhacomitrium 

 defoliatnm sp. nov., and Callicrgon sarmentosum var. subHaviim. 

 It is a very elongate, sterile form, with distant, long and narrow 

 leaves having long subulate points, but I cannot find any structural 

 difference from our northern species ; it has somewhat the habit of 

 certain of the forms of the var. trichodes, but the leaves do not 

 narrow so abruptly from the base to the subula as in that. 



New to Africa. Distribution : Northern and alpine Europe ; Cau- 

 casus ; Central Asia ; boreal parts of North America. 



CAMPYLOPUS STRAMINEUS (Mitt.) Jaeg. 



Campylopus substramincus Broth. Wissensch. Ergebn. der Deutsch. Zentral- 



Afrika Exped., 1907-8, Bd. II, Botanik, 139. 1914. 

 Campylopus scriceus Negri, Annali di Bot. 7 : 162. 1908. 



Loc. 3,630 meters, Nos. 1359, 1544, 1548, 1549, 1553, 1558, 1565, 

 I 577> 1578, 1594, 1598. Loc. 4,200 meters, Nos. 1655, 1659. 



Evidently one of the common mosses in and above the " giant 

 heath zone," and extremely variable in height, density, and length 

 of leaf, while apparently always retaining a certain general habit 

 and the straw to golden color from which it derives its name. 

 Brotherus (1) describes C. substramincus sp. nov. as " praecedenti 

 [i. e., C. stramineus] valde affinis, sed foliis duplo vel triplo longiori- 

 bus diversa." In going through the above numbers I recognized at 

 once that some of them must come under this plant, the"iong, silky 

 leaves giving a very different appearance to the plant; but it soon 

 became evident that it was going to be very difficult to draw the line 

 between the two, in fact a regular gradation occurred from plants 

 with leaves only about 3-4 mm. long to others where they are 7 mm. 

 long at least ; the longer leaf being usually, but by no means always,
