“Closely related to O. Kingianum Sull., but compared with a 
specimen from James ex herb., Lesqx., it differs as follows: More 
robust, leaves less erect, longer, less densely papillose, with the 
upper cells larger and less granulose, the lower ones much less 
enlarged and in the older leaves not at all pellucid ; capsule paler, 
narrower, exactly cylindrical when moist, etc. Compared with the 
description and figures in Icones Suppl. p. 74, t. 55, the leaves are 
much more acute and of a uniform texture throughout, costa ex- 
tending nearer the apex; capsule not obovate when moist, the 
mouth not broader when dry, teeth granulose, straw-colored, not 
rown.”’ : 
Through the kindness of Dr. Venturi I have a portion of the 
type of QO, stenocarpum. We also have Roll’s Number 606 from 
Roslyn, Washington, and four specimens collected by J. B. Leiberg 
on granite ledges at Lake Pend d’Oreille, and Rathdrum, which 
have been named by Dr. Venturi. We have no hesitation in say- 
mg that Austin’s species antedates Dr. Venturi’s, and this latter 
is doubly debarred by Bridel’s name of 1826, of which it is a 
homonym. 
Type locality on rocks, Cascades, British Columbia, Macoun, 
May 17th, 1875. Also collected by Réll on rocks near Easton, 
Washington, No. 604; near Rigi, Clear Lake, Washington, 900 ; 
Roslyn, 606; Ellensburgh, Thorp, 607, and by J. B. Leiberg 
near Lake Pend d’Oreille and Rathdrum, Idaho, 1888, Nos. 8

There seems to be some doubt to which species Kindberg’s e 
* should be referred. In his letters Dr. Venturi has said it wes Se . 
Same as Q. Stenocarpum, but in Ren. & Cardot's list it is cited as a 
‘ynonymn of O. Roellii. (Rev. Bryol. 19: 19, 1892.) fe 
This species has also exserted cylindric capsules with hoot
