Best : North American Pseudoleskea 235 



" Leaves ovate-oblong, short acuminate, cells sublanceolate, 

 conflated, irregularly sinuous ; costa not excurrent. Capsule un- 

 known, tufts brownish or olivaceous with green branch tips, 

 loosely cohering, without rhizoids. Branches subjulaceous, ir- 

 regularly divided; paraphyllia few." — Eur. & N. A. Bry. 53. 



Type locality, Griffin Lake, B. C. 



Duplicates of the type of this dubious species are in Prof. 

 Macoun's collection, no. 385. As it has been apparently col- 

 lected but once, and then in a poor condition, without fruit, it 

 would be well perhaps to suspend judgment until more and better 

 material is at hand.

' 1892 



In Prof. Macoun's collection are a few specimens bearing this 

 name, some of which are P. atrovirens, the others P. oligoclada. 

 The description in Macoun's catalogue, " leaves very papillose M and 

 u cells rotundate " evidently applies to P. atrovirens ; that in Eur. 

 & N. A. Bry. "leaves faintly papillose and cells oval-oblong " to 

 P. oligoclada. As both of these species antedate P. falcicuspis 

 it matters little of which it is a synonym so that its true standing 

 be recognized.

 I : 162. 1884. 



According to Barnes & Heald * this variety is found in Mon- 

 tana, Oregon and Washington. As I have seen no specimens of 

 it from these localities I can neither confirm nor deny its occur- 

 rence there. From Boulay's description slender forms of P. oligo- 

 clada might be taken for it and the same is true of P. denndata 

 Holzingeri. I am indebted to Mr. H. N. Dixon for a specimen 

 collected and named bv M. Boulav. It is a well-marked form of 



entirely distinct from that species.

&, 



mentosa closely resemble those of P. snbstriata, but the basal are 

 oblong-quadrate in several rows and the capsule is arcuate.
