306 ME. W. MITTEN ON MOSSES AND 



Wils. (Z. runcinafuSy C. MiilL), Z. Behmanni, C. Mull., and 

 Z. ruffifolins^ ejusd., all gathered in S. Africa by Dr. Rehmann ; 

 and agreeing very nearly with the S.- American Z< pentasHchus^ 

 Z. quitensiSy and Z. crennlatuSy Muse. Aust.-Amer. The Ana- 

 ealyfta stellatifolia^ Hampe, probably belongs to the same group. 

 The fruit is seldom in a state to afford a correct idea of the 

 structure of the iuterual peristome; but it is impossible to avoid 

 the considerations arising from an examination of the S. -American 

 species without recalling the remarks upon them by Wilson, 

 Bry. Brit. 264, in his notes on Palitdella ; and the more natural 

 arrangement may be to bring together Zygodon^ Paludella^ and 

 Atdacomnio7ij at least so far as relates to the bog species, if 

 indeed these two latter genera are truly more than steps higher 

 in peristomial development in a natural genus containing such 

 great diversity in that appendage as is observable in undoubted 

 Zygodons.

Hab. Kilimanjaro, Bishop Sannington ; he gathered it also in 

 the TJsagara Mountains. Cameroon Mountains, Mann ; Central 

 Madagascar, G. W. Parker. 



Entirely similar to B. (§ Brachymenium) nipalense in habit but 

 rather smaller in stature. It differs from B. fieccifolium^ from 

 Abyssinia, in its more strongly nerved and firmer leaves as well as 

 in the more regularly erect capsules. The form of the operculum
