Autoicous : plants pale or yellowish-green, sometimes brownish, 

 closely appressed to substratum or scattered among other bryo- 

 phytes : stems irregularly pinnate : leaves imbricated, the lobe 

 widely spreading, convex, broadly ovate, slightly falcate, arching 

 across axis but scarcely beyond, rounded or very obtuse at the more 

 or less decurved apex, entire ; lobule strongly inflated, ovate, 

 obliquely truncate or lunulate beyond the acute apex, keel slightly 

 arched, free margin more or less involute as far as the apex : under- 

 leaves contiguous or subimbricated, orbicular, not cordate at the base, 

 attached by a slightly curved line of insertion, bifid one fifth to one 

 third with subacute spreading or connivent lobes and narrow sinus : 

 leaf-cells papillose, with thin walls and small but distinct trigones : 

 $ inflorescence borne on a principal branch or on a short lateral 

 branch, innovating on one or on both sides, the innovations often 

 again floriferous ; bracts unequally bifid, the lobe falcate-oblong 

 or obovate, rounded at the apex, entire, lobule ovate or oblong, 

 rounded or obtuse at the apex, entire ; bracteole oblong, bifid 

 about one fourth with obtnse or subacute lobes and narrow sinus; 

 perianth obovate, gradually narrowed toward the base, rounded at 

 the apex and with a short beak, plane or nearly so on antical sur- 

 face, and with a broad two-angled postical keel, slightly compressed 

 on sides : 5 spike terminal on a simple, usually short branch; bracts 

 in two to ten pairs ; bracteoles wanting except near base of spike : 

 spores green, irregular in shape, but more or less oblong, with a 

 thickened, whitish, minutely tuberculate wall.

The determination of the present species is based on a plant in Mr. 

 Heller's collection, named by Herr Stephani. In a sterile condition, 

 Cheilolejeunea intertexta closely resembles several South American 

 species, named and distributed by Spruce, and among these, more
