MACOUN.] CATALOGUE OF CANADIAN PLANTS. 27 



base. Capsule curved, furrowed when dry, substrumose ; peristome 

 dark red ; seta 2 cm. long, solitary. 



This species could be considered as allied to D. strictum, Schleich., 

 and D. viride, Schimp., but differs principally in the form of the capsule 

 and in the less brittle leaves ; the costa is narrower than in JO. viride. 

 It has also affinity to D. majus, Turn. 



On the ground and on logs at Victoria, Vancouver Island, 1885 ; on 

 the ground in woods at Hastings, and at Agassiz and Sicamous, B.C., 

 1889. (Macoun.) 



(96.) D. crispulum, C. M. & Kindb. (n. sp.); Canadian Musci, No. 

 41, in part. 



Nearly allied to D. sulcatum, Kindb., but differing in having a 

 shorter stem, 2-3 cm. high, the leaves crispate, very much shorter, 

 0-5 0'8 cm. long, the costa less excurrent, rough at the back, the 

 alar cells smaller. 



On logs in woods at Comox, Vancouver Island, May 2nd, 1887 ; on

 92 ; Canadian Musci, No. 44, in part, barren specimens. 



Dioecious. Plants loosely tufted, about 9 cm. high, pale-yellowish. 

 Stem, tall sparingly radiculose. Leaves suberect, involute nearly all 

 around, not undulate, ovate-lanceolate, narrowed into a short obtusate 

 or subacute acumen, nearly entire or with a few small teeth at the 

 apex ; cells not porose, narrow except the basilar ; alar cells brown, 

 median basal cells hyaline, inner yellow near the costa ; costa smooth 

 and faint, ceasing below the acumen, T L of the leaf near the base. 

 Barren. 



This species has no affinity to the other Canadian Dicrana and is 

 very distinct in the long-celled, nearly entire leaves and the costa 

 narrow. In habit it may be compared with some forms of D. scoparium, 

 Hedw.
