237. H. Stokesii, Turn.

 Island, Lyall, Wood. 



238. H. Oreganum, Sulliv. 



Ilab. in woods, on decaying logs or on the ground, Bol., Brew., Big.; Puget 

 Sound, Oregon, U. S. Wipes' Exp.; Vancouver Island, Wood. 



I 7. RYXCHOSTEGIUM, Bryol. Eur. 



239. H. rusciforme, Wcis.

g 8. THAMNIUM, Bryol. Eur. 



240. H. Bigelowii, Sulliv. 



Ilab. on shaded rocks, in caiions, Biy., Bol., Br<:w. 



241. H. Neckeroides, Hook. 



Ilab. Vancouver Island, Wood. 



According to Mitten, we have, in the United States, in this division of the Hyp- 

 nacea3, H. Neckeroides, Hook., found by Drummond in St. Louis ; II. alopecurum, sent 

 from Boston, and H. Alleghaniense, Mull. Though we have examined, with Mr. Sulli- 

 vant, a great number of specimens, either collected by ourselves or sent from various 

 points of the United States, we have never been able to find any species different from 

 that of II. Alleghaniense, Mull, which differs from H. alopecurum by the inflorescence 

 only. This // Alleghaniense is the same moss as No. 119 of Drummond, H. Neckeroides, 

 quoted by Mitten. And as the male flowers are rarely found on fruiting plants, in- 

 complete specimens are often taken for H. alopecurum. I believe, therefore, that these 

 three species, quoted by Mitten, are, for American specimens, referable to the same 

 H. Alleghaniense, Mull. H. alopecurum from Europe, and H. Neckeroides, Hook., from 

 New Zealand, are indeed different, but not yet found in our country.
