Hyrpnum, Dill. 
(Homalothecium et Camptothecium, Schimp. ) 
H. Nvrrauuı, Wils. ; 
Hab. Vancouver Island, Lyall; California, Coulter ; N.W. Coast, 
Douglas, 
. In its capsule er intermediate between H. sericeum and 
H. lutescens. 
H. turescens, Hedw. 
Hab. Vancouver Island, Lyall: collected also by Douglas. 
Specimens very large, and capsule rather longer than in the 
common European form. 
H. ÆNEUM, sp. nov. Dioieum, foliis inferne ovatis sensim lanceolato- 
acuminatis plicatis, nervo infra apicem evanido, marginibus reflexis 
remote serrulatis, cellulis basi ad angulos pluribus parvis abbreviatis 
obscuris, superioribus elongatis angustis, perichætialibus elongatis 
erectis late lanceolatis apice subito subulatis serrulatis enerviis, theca 
in pedunculo scabro cylindracea inclinata curvata, peristomio interno 
processibus angustis perforatis ciliis tribus subzequilongis interpositis 
in membrana ad tertiam dentium longitudinis exserta, habitu omnino 
H. lutescenti simile. 
Hab. Pend Oreille River, British Columbia, Lyall. 
A single fertile stem with two capsules and a few stems with 
male flowers are all that has been seen of this moss ; it resembles 
H. aureum, Lagasc., in size and general appearance, but the leaves 
of the stems are not so deeply plicate, and the apices lanceo- 
late and serrulate, not attenuated into a smooth hair-like- point. 
in the apices of the lateral branches the leaves have their points 
broad, somewhat acutate, and obtuse; by this particular the 
specimens are readily distinguished from H. lutescens as well. 
H. NITENS, Schreb. 
Hab. Saskatchewan, Bourgeau ; Pack River, British Columbia, Lyall. 
(Ptychodium et Lescurea, Schimp.). 
H. RADICOSUM, sp. nov. Dioicum, intricate ezspitosum, folis paten- 
tibus laxe imbricatis in apicibus ramorum subsecundis ovato-lanceo- - 
latis acuminatis concavis nervo percurrente, marginibus reflexis apice 
serrulatis, cellulis basi pluribus abbreviatis rotundatis, superioribus 
oblongis mollibus, paraphyllis parvis lanceolatis, perichetialibus mag- 
nis erectis convolutis elliptico-lanceolatis acuminatis, externis enerviis, 
internis ad medium tenuiter nervatis apice subserrulatis. 
Hab. Banks of the Portage River, Drummond, no. 225 (H. tenaz).
