OF THE FORTY-NINTH PARALLEL OF LATITUDE. 31 



Htpnum, Dill. 



(Homalothecium et Camptothecium, Schimp.) 



H. NUTTALLII, WUs. 



Hab. Vancouver Island, Lyall; California, Coulter; N.W. Coast, 



Douglas. 

 In its capsule completely intermediate between H. sericeum and 

 H. lutescens. 



H. lutescens, Hedw. 



Hab. Vancouver Island, Lyall : collected also by Douglas. 

 Specimens very large, and capsule rather longer than in the 

 common European form. 



H. ^neum, sp. now Dioicum, foliis inferne ovatis sensim ianceolato- 

 acuminatis plicatis, nervo infra apicem evanido, marginibus reflexis 

 remote serrulatis, cellulis basi ad angulos pluribus parvis abbreviatis 

 obscuris, superioribus elongatis angustis, perichsetialibus elongatis 

 erectis late lanceolatis apice subito subulatis serrulatis enerviis, theca 

 in pedunculo scabro cylindracea inclinata curvata, peristomio interno 

 processibus angustis perforatis ciliis tribus subsequilongis interpositis 

 in membrana ad tertiam denttnm longitudinis exserta, habitu ornnino 

 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 crespitosum, foliis 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, perichsetialibus mag- 

 nis erectis convolutis elliptico-lanceolatis acuminatis, externis enerviis, 

 intends ad medium tenuiter nervatis apice subserrulatis. 



Hab. Banks of the Portage River, Drummond, no. 225 (H. tenax). 



So far as can be seen in the incomplete specimens, which are
