Liochl^ina, Nees. 

 L. lanceolata, Nees. 

 Hab. Mooyie River, British Columbia, Lyall. 



Solenostoma, gen. nov. 

 Ferianthium terminale, obovatum, superne quinqueplicatum, 

 ore in tubulum brevem contracto rostelliformi. Folia di- 

 sticha, integra. Amphigastria parva obsoletave. 



S. Tersum, (Jungermannia) Nees. 

 Hab. Galton Mountains, Lyall. 



Two species only of this group are yet certainly known from 

 the whole of N. America. The other species, S. crenulatum {Jun- 

 germannia, Sm.), is indicated by Sullivant in Alabama. 



This genus, long confounded with Jungermannia, differs from it 

 in the form and plication of the perianth, which is similar to that 

 of Lejeimia and Frullania, and only becomes dentate at the apex 

 by the bursting through of the capsule. 



Leiosctphus, Mitten. 

 L. Taylori, Hook. 

 Hab. Cascade Mountains, Lyall. 



Plagiochila, Nees et Mont. 



P. asplenioides (Linn.). 

 Hab. Fort Colville, Lyall. 



Lophocolea, Nees. 

 L. heterophylla, Hook. 

 Hab. Fort Colville, Lyall. 



The few fragments supposed to belong to this species are merely 

 sufficient to indicate the presence of something very nearly allied, 

 if not identical.

 Ann. fy Mag. Nat. Hist. s. 2. vol. v. p. 207.

to J. Starkii.
