Colorado, Pr. Brandegee, (Rau.) 
The chief distinctive characters of this species are the light costa, 
minute areolation of the upper part of the leaf, the erect cribrose 
broad lanceolate peristomal teeth, the short much crimped pedicel 
and strongly ventricose-gibbous base of the capsule. e inflo- 
rescence not seen. 
Near G. plagiopodia, Hedw.; but that is of a fuscous green or 
- grizzly color, leaves ovate or oblong-ovate, mostly obtuse, costa 
stouter more widened above, capsule wider mouthed when dry, 
operculum convex, teeth of the peristome widely spreading when 
dry, annulus much narrower, etc. Shape and texture of the leaf 
about as in G. Jamesii (Aust. inthe BuLtetrn for June, p. 43,) but, 
besides other differences, that has a much stouter costa, a larger darker 
colored nearly globose capsule on a straight (or nearly so) pedicel, 
a convex-conic operculum and a large subcucullate calyptra. 
Grimmia brachyodon, n. sy.—Plante parvule cespitose; caule 
perbrevi, foliis laxiuscule dispositis siccitate vix mutantibus sub- 
flexuosis, inferioribus lineali-lanceolatis valde concavis pilo brevi 
instructis, superioribus vblongo-lanceolatis sublingulatisve concavis 
(haud ecarinatis) margine planis apice in pilum longum incanum 
productis, costa sursum leniter incrassata sub apice evanida, reti 
subsinuoso basilari laxiusculo brevi quadrangulari, capsula in 
pedicello brevi curvulo subexserta ovali in siccis truncato-obovatis 
striatulis, operculo deplanato in medio mammillato-umbonato, an- 
nulo nullo? peristomii dentibus brevissimis truncatis valde cribrosis 
in siccis patenti-recurvis ; calyptra haud visa : florescentia dioica ? 
pl. mase. ignota —Grimmia Montana, var. Sulliv. & Lesqx. Exsice. 
Ed. 2, n. 215, pro parte. : : : 
The distinctive dberastar of this species are its small size, short - 
slightly curved (not twisted) pedicel, flat (always ) operculum, 
short truncate cribrose peristomal teeth, regular substriate capsule, 
subsinuous areolation very gradually passing into short rectangu- 
lar towards the base, where it is somewhat enlarged and subpellu- 
cid. Resembles in some respects the European G, eurvula, Bruch ; 
but that has the leaves longer and with longer hair-points, areola- 
tion not sinuous and suddenly becoming much longer and more lax 
below the middle, capsule on a strongly twisted pedicel, somewhat 
urceolate when dry, operculum more convex, peristomal teeth large,
