lar to G. cygnicoUis, in wet subalpiue places often longer and 

 closely tufted ; stems commonly about 1 cm. Leaves crecto- 

 patent, lanceolate, undulate, smooth, 2 m.m., tipped with a 

 shorter, smooth, or slightly dentate, colourless apex, con- 

 cave; margin plain or revolute, slightly thickened; nerve 

 canaliculate, lost in the apex. Seta flexed, 3 m.m. ; capsule 

 pale, erect, 0.7 m.m., oblong, with 8 faint ribs; lid red 

 conic to rostrate, half as long as the capsule; calyptra 

 with 3. short, narrow base; peristome teeth erect or re- 

 curved, red, bifid.

GRIMMTA LEIOCARPA, Tayl. 



Syn : G. leucophoea, Grev. 



Small, forming dense, dark tufts, or hoary with the 

 leaftips ; sterna about 1 cm. Leaves squarrose, erect 

 when dry, ovate, tapering to a hyaline dentate hair, 1.5 

 m.m., the hair point about the same length, opaque; 

 margin plain ; nerve not thick, vanishing below the 

 apex. Seta erect, about 1-2 m.m.; capsule erect, broadly 

 oblong, 0.8 m.m.; lid small, conic-rostrate; calyptra much 

 exceeding the lid; peristome teeth short, bifid. 



Doubtfully distinct from G. campestris, Burch.

BHACOMITRIUM, Bridel. 



Robu&t in loose mats, stems elong-ated with short, 

 lateral branches, rarely branching dichotomously and 

 equal. Leaves lanceolate to ovate with or without a col- 

 ourless tip ; nei"ve slender ; cells short above, quadrate, 

 narrow linear below, except in R. crispulum, the walls have 

 a boldly sinuous outline. Seta slender, rather short, usual- 

 ly on a short lateral branch; capsule oblong, smooth; lid 

 acutely rostrate ; calyptra mitriform with a short, broad, 

 lacerated base; peristome single, teeth short, lanceolate, 

 more or less split into pruinose slender legs. 



The genus is continuous with Grimmia, in which it 

 is often included. There is no consistent mark of dis- 

 tinction, as the sinuous walls also occur in G. apocarpa.
