68 Drxon: NEW AND RARE AFRICAN’ MOSSES 
There is a good deal of confusion about the nomenclature of | 
this plant, which is very near the northern A. filiforme (Dicks.) 
Husn., but which may perhaps be separable on the ground of its : 
slightly pointed leaves and less highly appendiculate cilia. : 
Rehmann issued his Musci austr.-afr. 274 as Mielichhoferia : 
procerrima; this C. Miiller gives as a synonym of his Brywm prom- 
ontorii. Paris, Index, Ed. 2, under the latter name gives as 4 
synonym Mielichhoferia procumbens Rehm., which is no doubt ‘ 
simply a slip for procerrima. A more serious error lies in the 
fact of his retaining Brywm promontorii C. Miill. (with M. ; 
procerrima Rehm. 214 as a synonym), and at the same time : 
Anomobryum procerrimum Rehm. 540, giving M. procerrima Rehm. — 
219 as a synonym. This would seem to imply that Rehmann’s | 
214 is a different species (and genus) from his 2z9 and 540. But | 
Rehmann has himself cited his 274 as a synonym of his Amo 
mobryum procerrimum Rehm. 540 (on the label of the latter), 2 
and there can be no ground for separating them. 4 
Brotherus cites the plant as ‘ A[nomobryum | procerrvmum 
(C. Miill. als Bryum),” but this too appears to be an error. The 
synonymy should, I believe, stand thus:. |
