Var, atricha, Kindb. (n. var.) 



Differs principally in the tufts being very dense and soft-fuscescent 

 with green tips, stem very lax, nearly without paraphyllia and rhizoids. 



On rocks along the Eagle River, just below the bridge at Griffin 

 Lake, B.C., August 13th, 1889. (Macoun.) 



(680.) P. oligoclada, Kindb. Bull. Torr. Bot. Club, XVIL, 211. 



Allied to Pseudoleskea atrovirens, but very different in smaller leaf- 

 cells. Tufts loose, dark brown, sparingly I'adiculose. Secondary 

 stems sparingly branched ; branchlets distant, short and julaceous, 

 paraphyllia numerous. Leaves crowded, not decurrent, appressed 

 when dry, falcate when moist, reflexed on the borders generally to the 

 middle, abruptly attenuate from the short ovate base to the longer, 

 sub-entire acumen, not striate ; cells very small, faintly papillose, not 

 confluent, short with incrassate walls, rotundate or quadrate, only the 

 upper-most narrow ; costa brown, stout, vanishing into the acumen ; 

 perichetial leaves longer, acuminate, scarcely reflexed on the borders ; 

 cells narrower ; archegonia 10-12, paraphyses few, shorter. Did'cious. 

 Capsules and male plants unknown. 



On damp rocks. Mount Benson, Nanaimo, Vancouver Island, June 

 8th, 1887. (Macoun.) 



M. Cardot believes that this plant is a variety of Pseudoleskea 

 atrovirens. 



(681.) PJsciuroides, Kindb. Bull. Torr. Bot. Club, XVII., 276. 



Macounia sciuroides, Kindb. enumer. bryin. exot., 1888. 



Plants loosely cohering. Stems sparingly branching, more or less 

 radicant ; paraphyllia numerous ; branches pale-green, curved above.
