240 BRYACE^. [Bryum. 



reflexed to the base, crispulate when dry ; costa broad and red- 

 disli at base, narrowed upward and percurrent ; areolation loose, 

 the cells chlorophyllose : male plants generally in separate 

 tufts, the comal leaves shorter and broader, spreading star-like : 

 capsule single or two or three in the same perichajtium, pendent 

 on a long solid dark purple pedicel, oblong-conical, slightly 

 incurved, rarely obovate-oblong, not constricted under the orifice 

 when dry, solid ; lid mammiform, dark purple ; teeth very long ; 

 inner membrane orange-colored; segments lacunose along the 

 keel; annulus revoluble. — Spicil. Fl. Lips. 84; Bryol. Eur. 

 t. 365. 



Hab. Shaded pine woods, base of trees, on shaded rocks covered with 

 humus; not rare on the Eastern slope. Found also in California by Bo- 

 lander. 



The most beautiful species of the genus, like a Mnium in appearance, 

 but closely allied to B. capillare in its characters. 



42. B. COncinnatum, Spruce. Dioecious : plants small, 

 cespitose, cohering by radicles below ; stem about 2 cm. long, 

 erect, julaceous, slender, filiform from the base, reddish below, 

 green above : leaves erect-appressed, broadly ovate or oval- 

 lanceolate, carinate-concave, apiculate by the slender subexcur- 

 rent costa; borders erect and very entire; upper areolation 

 narrowly rhomboidal, the basilar quadrate. — Muell. Syn. ii. 575. 

 Hab. Kaaterskill Falls, Catskill Mountains (C II. Peck). 



86. ZIERIA, Schimp. 

 Plants short, cespitulose, branching by innovations under the 

 flowers, then dichotomous. Stems radiculose up to the apex. 

 Leaves soft, more or less densely imbricate, ovate and oblong- 

 acuminate, apiculate or cuspidate by the excurrent costa; are- 

 olation broadly hexagonal-rhomboid al. Flowers gemmiform. 

 Capsule horizontal or curved down, short-pedicelled, very long- 

 necked, narrowly elliptical, sporangium inflated. Lid small, 

 convex-apiculate, oblique. Peristome double ; the teeth nar- 

 rowly lanceolate, remotely articulate ; inner membrane divided 

 into narrow segments, often united at the apex by transverse 

 divisions, separated by rudimentary cilia. 



1. Z. julacea, Schimp. Tufts soft and loose, silvery white ; 

 stems short, divided into numerous erect branchlets: lower
