2b. Eleutera pennata pterantha (C. M. & Kindb.) nom. nov. 



Gametophyte : secondary sterns nearly simple, about 1 dm. in 

 length, rigid and robust, erect : one branch of costa often reaching 

 to the middle of leaf: paraphyllia numerous. Sporophyte : cap- 

 sule emergent. (From Greek ptcros, wing, and anthos, flower.) 



Type locality, rocks, Hector, B. C, the only locality from 

 which it has been collected. 



Syn. : Neckera oligocarpa var. pterantha Kdbg. in Herb. Can.

In case we begin with Hedwig, 1792, for nomenclature, the in- 

 itial " L." in the species should be replaced by " Hedw." 



On the original label in Herb. Can. Geol. Survey in what I 

 take to be Kindberg's writing, the name of the variety is given as 



pterantha ; for this reason that name is adopted instead of peter- 

 ant ha, which is evidently a slip, and quite meaningless. 



All gradations occur between the species and what has been 

 known as N. oligocarpa, so that we must recognize that as a mere 

 variety. These slight and varying differences were recognized by C. 

 F. Austin, who, on a label in the Columbia University Herbarium, 



says : 



P 



for distinguishing between oligocarpa and pennata." Some of 

 these gradations are : Coarse plants with very narrow leaves and 

 attenuate branches ; very robust plants with lingulate leaves ; deli- 

 cate plants with obtuse branches and narrow leaves. 



Eastern American specimens of the var. oligocarpa agree with 

 European specimens in having no paraphyllia, but specimens from 

 Vermilion Lake, Minn., west to the Rocky Mountains have a few 

 paraphyllia, tending toward var. pterantha. 



3. Eleutera Menziesii (Drumm.) nom. nov. 



Gametopliyte large, yellowish-green, brown when old : primary 

 stems 8- 10 cm. : secondary stems 5-25 cm. in length, flat, densely 

 pinnately branched: branches 1-10 cm., becoming flagellate at
