 gined, plane on the margin; cells at the base more or less cjuadrate, above oval or ot)- 

 long; eosta ceasing below or at the apex. Frnit not seen. Much like the vai'. of /»/•. 

 \fi(n,niii, mentioned above, but that has the leaves all obtuse, and very indistinctlv 

 if at all margined. There is another sterile (always?) Brymn growing in great profus- 

 i(ni on the White Moimtains, associateil witli the preceding and with Leptntrichniu 

 heteromaUuM. It resembles JfielicMoferid nituhi in most rcspcn-ts, l)ut is larger with 

 the stems often tlagelliferous. It also occurs on the mountains of New York and New 

 Jersey, and I have hail it in mv herbarium for the past ten years under the lu-ovisional 

 name of Bri/u/i/ rot/iparfuiti.
