he J?cJ7' leans, and as the remarks under this species both in the Lesquereux 

 & James' Manual and in SuUivant's " Icones" are somewhat misleading, the 

 following notes may be of interest: 



The species grows in separate tufts, as well as mingled with /iygro»ietyica, 

 from which it may be distinguished by average smaller size, erect pedicel, 

 more pointed leaves, and mouth less oblique, as well as less furrowed cap- 

 sule, which matures a week or two earlier than in hygroiiietrica, in this 

 region at least, where the best specimens were collected from the ist to the 

 loth of June. When well ripened, the capsules are very dark reddish, with 

 alow convex lid not apiculate. The mouth of hygyo>iietyica measures about 

 ten-fifteenths mm. across, ol flavicans eight-fifteenths to nine-fifteenths mm , 

 and of F. jiiicrostoDia about one-half mm. The spores of the first measure 

 up to about .oiS mm., of the other two, up to about .025 mm. F. JJavicaiis is 

 essentially a southern species, Austin only, I believe, having collected it a 

 little farther north than this, near Closter, N. J. — A*. 5. Il^i7lia>?is, Xt'i^'

"Gkimmia Holzin'ceki Card. & Ther. sp. nov. — Very sniall, slender, in 

 small cushions, dull green, fuscous below. Stems erect. 4-0 mm. high, spar- 

 ingly branched, branches st)metimes attenuate, subfiagellate. Leaves 

 crowded, very small, 0.50-0.70 mm. long, 020-0.35 mm. broad, erect when 

 moist, appressed when dry, shortly ovate-oblong, concave, all obtusely 

 acuminate, margins plane, entire: costa channeled, reaching the apex, 0.02S 

 mm. broad at base, upper cells bistratose, quadrate-subrotund, the lower cells 

 larger, unistratose, yellow, the lowest oblong or sublinear, all incrassate. 

 Other parts unknown. 



"This very minute species, resembling in habit the small forms of 

 A)ufredc'a petrophila, is quite distinct from all the European and North 

 American species of Grinniiia with muticous leaves by the small size, and 

 the shape and areolation of the leaves. — Base of Sperry glacier, .Mt. Trilby."

"Grimmia (Eugrimmia) ManniaI': n. sp. : dioecious; in delicate crowded 

 intensely green cushions; the fastigiately branched stems very slender. 

 densely leafy, loosely cohering and obtuse at apex: stem leaves closely 

 imbricated, small, from a broad truncate base extended into an open deeply 

 keeled lamina which is obtusely short-acummate, their erect margins very 

 entire, slender costa green, excurrent to percurrent, small basal cells green- 

 ish but empty, hexagonal, somewhat thick walled, the upper cells minute 

 and indistinct: perichaetial leaves densely imbricated, several, larger, more 

 obtuse, areolation larger, more involute (i, e. rolled u])) ; all leaves some-

 coriaceous, pachydermous, red, raised on a reddish slender slightly spirally 

 twisted seta, which is rather long exserted considering the small size of the
