THE MOSSES OF ALASKA 333 



In his valuable Revision of the North American species of Psetcdo- 

 leskea (Bull. Torr. Bot. Club, xxvii), Dr. Best has substituted the 

 name P. rigesce7is (Wils.) Lindb. for P. stenophylla Ren. & Card. 

 It is impossible for us to admit any ^vell grounded reason for this 

 change ; for, if Dr. Best saw, as he affirms, a specimen of Leskea 

 rigescois Wils. identical with P. stenophylla Ren. & Card., on the 

 other hand, we possess one which certainly belongs to P. radicosa 

 (Drummond, Musci Americani, no. 225). Moreover, Dr. Best him- 

 self acknowledges that both species were mixed up under this number 

 of Drummond's exsiccata and under the name Hypn7{m congestuni 

 Hook. & Wils. Now, as Wilson never described his Leskea rigescens^ 

 it is impossible to know to which of the two species he wished to give 

 this name, and that must, therefore, be definitely abandoned. One of 

 the two species should be called P. radicosa (Mitt.) Best, the other 

 should preserve the name P. stenophylla Ren. & Card.

 (J. M. Macoun). 



Kindberg mentions C crispifolium and C. laxifolium as coming 

 from Alaska. His specimens of crispifolium that we have seen be- 

 long to C. bolanderi. We have not seen any of the second one. 

 Otherwise, it has been established that Leskea laxifolia Hook, is none 

 other than Brachythecium refexum Br. eur. 



Family HYPNACE.E.
