136 THE JOURNAL OF HOT ANY 



This Campbell Island plant is no Ectropothecium, but an Iso- 

 pteryaium, and the correct synonymy is as follows : — 



Isopterygtum LiMATUM (H. f. & W.) Broth, in Engl. & Prantl 

 Pflanzenfam. Musci, ii. 1080 (1908). 



Syn. H. limatum H. f. & W., PL antarct., Suppl. ii. 345 (1847). 



H. terrce-novce var. australe eor., Fl. antarct. i. 142 (1844). 



H. australe C. M., Syn. ii. 302 (1851). 



Ectropothecium australe Jaeg. Adumbr. ii. 524 (1877-78). 



Barbula apoclada Par. 

 C. Mueller in Linnsea, xlii. p. 334 (1878-79) describes Barbula 

 subrevolutaa.su new species from Argentina. As Hampe had already 

 published a Barbula subrevoluta in Linnaea, xxxviii. p. 208 (1874), 

 Paris in the Suppl. Ind. bryol. p. 20 (1900) has re-named 0. Mueller's 

 species as above. In doing so, however, he has overlooked the fact 

 that C. Mueller had detected the error, and had already corrected it 

 (in his emendenda to Prodr. Bryol. Argent.) in Linnuea, xliii. p. 486 

 (1880-82), where he alters his former name to Barbula perrevoluta 

 loco B. subrevoluta. Paris's Barbula apoclada is therefore super- 

 iluous. 



Papillosity of Leaves in Schwetschkea. 



I was rather surprised in examining a species of this genus col- 

 lected by R. A. Dummer in British East Africa (no. 4238) to find 

 the leaves highly papillose at back. Smooth cells are supposed to be 

 a character of the whole family of the Fabroniacese, to which 

 Schwetschkea belongs, and 1 have never seen papillose cells in any 

 other member of the family. Otherwise the plant agreed well with 

 the description of S. usambarica Broth., and on comparing it with 

 original specimens of that species at Kew (L T sambara, Hoist, 

 no. 3285) I found that the papillae occur there, not quite so strongly, 

 and variably, but very markedly. The papilla? are rather large, 

 conical ; they are placed at the apex of the cell, but they are some- 

 what of the character of those obtaining in the Bartramiaceaj ; it is 

 not at all a question of a slight prominence of the cell apex such as 

 is common in certain genera, as Ctenidium, Bseudoleskea, and 

 Porotrichum. 



It may be added that there is no doubt that the plant is a true 

 Schwetscltkea. 



Myurium Foxworthyii (Broth.) Broth. 



Among some mosses sent me for determination from the her- 

 barium of the late H. Boswell, of Oxford, was one of which the 

 original labelling was " Dicranum [afterwards erased]. No. 2209. 

 Cuming." A later author had added some notes "....? Leucodon 

 vel affine." On examination I found that it was probably a Myurium, 

 and further investigation showed that it was undoubtedly M. Fox- 

 worthyii Broth, (originally described by him as (Edicladium Fox- 

 worthyii in Philipp. Journ. Sci. iii. 23 [1908]), based on a fertile 

 specimen gathered on Mt. Banajao, Luzon, by Foxworthy ; after- 

 wards placed by Bi'otherus in a new subgenus (Pseudo-dieranum) of 

 Myurium. Cuming's Philippine mosses, collected about 1835, were
