Grimmia anomala Hpe mss. Schpr. 



Among some mosses collected by Sir James Stirling in 

 the Alps during last summer, there occurs a specimen of 

 the above moss collected on a " Rock above Mer de Glace, 

 near the Hotel Montanvert, Chamonix, Haute-Savoie, 

 6-7,000 ft. Aug. 1899. " G. anomala has not hitherto, I 

 believe, been recorded from France. The species was 

 originally discovered on damp rocks at Zermatt, Switzerland 

 (Bertram, 1873), and described by Schimper (Syn. II, 

 p. 270) in 1876; Limpricht (Die Laubmoose, Abth. [, p. 768) 

 records it from Bavaria (Algau : Pointalpe im Berggiindle 

 auf rothem Hornstein, 1298 m. (Holler, 1884) und Schnip- 

 r'"kopf aut Flysch, 1700 m. (Holler, 1885); and M' H. N. 

 t. I has send me a specimen collected m Norway 

 rj ersdale, lat. bor. 59 1/2° ad rupes siliceas, alt. 800 m. 

 Aug. 1897, Leg. N. Bryhn : comm. D'' Hagen). 



In Schimper's herbarium, at Kew, there are some 

 unpublished drawings of G. anomala, and as the species 

 has not hitherto been figured, I have reproduced Schimper s 

 drawings at Plate I, and supplemented them with figures 

 drawn from the Mer de Glace specimens. 



Limpricht (1. c. p. 767) gives a full and admirab e des- 

 cription of G. anomala. The leaves are described as 

 " widely acuminate, bluntish and mucronate through the 

 coarsely toothed, short hair-point, the latter sometimes 

 absent, and the leaf-apex almost emargmate. This des- 

 cription applies to the great majority of leaves (see hga. 

 4 5 14-16, 19), but as has already been noticed by 

 Schimper (see fig. 18) there ocaur occasionally leaves with 

 a gradually acuminate apex terminating in a hyaline or 

 greenish-yellow denticulate hair-point, quite similar to 

 that found in, e. g. G. ^armzflw/. These latter (see figs. 7 8) 

 show, I think, the original shape of the leaf, the rounded 

 apex and broadened nerve (fig. 5) being probably modifi- 

 cations due to the production of gemmae.
