-or fugaceous. Calyptra yellowish, fuscous at apex. Covered with numer- 

 ous long, toothed, papillose hairs. Spores papillose, 20-22yU in diameter. Male 

 flowers unknown. 



Idaho: Moscow Mountains, on rocks (L. F, Henderson, 1893). 



By the superficial stomata and the peristome reflexed when dry and 

 finely papillose, this species belongs to the group of O. arcticuju Sch., but is 

 easily distinguished from all the other species of this group by its lax tufts, 

 emergent capsule, and peristomial teeth less opaque, covered with less dense 

 papillae. 



Orthotrichum Lyellii H. & T. var. Howei Ren. & Card. var. nova. 



Differs from the typical form in the exserted capsule on a seta equalling 

 it in length, and in the leaves revolute from near the middle. Distinguished 

 from O. papillosum by the less flexuous leaves, strict when dry and longer 

 revolute, with shorter and less narrow acumen. Calyptra very hairy. 

 Papillae of the leaves not very prominent. Leaves often furnished with sev- 

 eral gemmae. 



California: region of the upper Sacramento, Sisson, on trunks of 

 ^uercus Kelloggii (Marshall A. Howe, 1884. Ren. & Card. 'Musci Amer. 

 sept, exsicc. No. 291).

Northwestern Montana : in the vicinity of Lake MacDonald, Flathead 

 County, (J. M. Holzinger and J. B. Blake, 1898). 



By the habit and dioicous inflorescence this moss approaches W. com- 

 imitata Sch. from which it differs in the more slender stems, the leaves 

 always plane on the borders, distinctly carinate on the back, imbricate in five 

 rows, and the cell walls thinner. 

 Bryum euryloma Card. & Ther., sp. nova. 



Dioicous, densely caespitose, lurid green. Stem erect, tomentose, 2-3cm. 

 high. Leaves crowded, erecto-patent when wet, subappressed when dry, 

 lanceolate from a narrow decurrent base, 3-4mm. long, o.65-o.75mm. broad, 

 gradually and finely acuminate, entire or very slightly denticulate at the 

 apex, narrowly revolute on the margins, sometimes nearly plane on one side ; 

 costa excurrent in a very short, acute, subentire or toothed point which is 

 often hyaline at the apex. Areolation as in B. pseitdotriquetrum but the 

 border wider, composed of 5-6 rows of cells. Inner perichaetial leaves 

 smaller, triangular-lanceolate gradually cuspidate, margins plane. Seta 

 i5-2omm. long, dark purple at base. Capsule abruptly pendulous, narrow, 

 subcylindrical. constricted under the mouth when dry, with a long neck 

 tapering gradually into the seta, 2.5o-4mm. long, 0.75-imm. thick. Oper- 

 culum convex apiculate. Peristome as in B. pseudotriqtietruin. Male in- 

 florescence discoid.
