HYOPHILOPSIS, A NEW GENUS OP POTTIACEJi; 149 



it seems desirable to retain the name given to it by Eehmann ; 

 (b) two specimens from Southern India, viz. one from Ceylon, 

 " Bry. argenteum L., Centr. Prov,, Ceylon, C. M. Ill " (i. e. Ceylon 

 Mosses, No. Ill, issued by Thwaites) — the middle specimen only — 

 the other a specimen from the Nilghiris, leg. Schmidt in Hampe's 

 herbarium ; part of this is separated as having " theca subrotunda," 

 evidently a "sport" or pathological condition only. Numerous 

 specimens from the same localities are quite typical B. argenteum. 

 The var. australe appears to be a well-marked variety with a wide 

 but at present clearly defined area, viz. the South of India and the 

 South and East Central Africa. It appears to occiu' on Mount 

 Ruwenzori, for, as Mons. Cardot points out to me, the plant 

 recorded by Dr. Negri, on p. 17 of his Memoir on the Mosses of 

 Buivenzori of the Duke of the Abruzzi's Expedition, as B. ellipsi- 

 folium C. M., probably belongs here ; the description, " Li dimen- 

 sion! sono assai maggiori di quelle del B. argenteum, e le foglie 

 caratteristicamente orbiculari," does not apply to C. Milller's 

 species, but agrees well with the var. australe. 



The Indian plants are slightly more robust than Rehmann's, 

 but in all other points they are identical. C. Miiller makes a 

 purple nerve a strong character of his B. oranicum (" nervo 

 angusto intense purpureo "), but the British Museum specimen of 

 Eehm., no. 260, shows no trace of such a structure; the nerve at 

 the most is reddish at the base of some of the leaves.

 var. nov. Folia pro more latiora, 1*5-2 mm. longa, -G-"? mm.

A rather strongly marked variety, bearing somewhat the same 

 relationship to the type that B. Mildeanum has to B. alinnum. 

 The leaf-apex is sharply denticulate, though the character is often 

 masked by the strongly recurved margin. 



Mons. Cardot informs me that B. p)lumosiforme Ren. & Card, 

 must be referred to B. pseudo-alinmLin.

B. strigosuyn, it should be noted, is a nomen nudum, being un- 

 accompanied by any description.
