204 BRYACE^. [Bartramia. 



* Capside erect^ symmetrical: peristome none or simple. 



1. B. Menziesii, Turn. Plants more or less densely cespi- 

 tose; steins 5 to 10- cm. long or more, simple or sparingly- 

 branched, brown within the tufts, bright or yellowish green 

 above: leaves closely imbricate, erect or half open, concave, 

 plicate and reflexed on the borders at the enlarged ovate base, 

 lanceolate, subulate-dentate above ; costa stout, j^ercurrent, 

 rough on the back; j:)erichcetial leaves similar; perigonial 

 broadly ovate, deeply concave at base, abruptly long-subulate, 

 scabrous on the back: flowers dioecious; male plants shnple, 

 shorter, the flowers terminal or lateral by innovations, gemma- 

 ceous ; antheridia curved, yellowish brown with numerous long 

 filiform paraphyses ; fruiting flowers lateral by innovations : 

 capsule erect, broadly oval, symmetrical, pale brown ; pedicel 

 short, 1 to 2 m.m, long, pale red or dark yellow, twisted to the 

 left ; lid conical, obtuse : peristome simple, of 16 short lanceolate 

 irregularly articulate reddish teeth, sometimes rudimentary or 

 none. — Koen. & Sims, Ann. Bot. i. 525, t. 11, f. 1; Hook.

Hab. California, not rare; Spokan Falls ( Watson). The normal form 

 on shaded rocks in the woods, varying on dry exposed rocks. 



Tlie species varies according to its habitat. On dry exposed rocks the 

 steins are shorter, the shghtly shorter and narrower leaves, appressed 

 when dry, are open and erect when moistened ; the capsule is somewhat 

 longer and naiTower; the peristome either wanting or fragmentary and 

 reduced to a pellucid membrane more or less irregularly lacerated. This 

 is the variety n. 260 of the Muse. Exsicc. (n. 259 by mistake), and repre- 

 sents Gli/phocarpa Baueri. It is not possible to ascertain which of the 

 two forms represents the original species of Hooker, as no author appears 

 to have seen the peristome complete. The specimens in Taylor's herba- 

 rium have longer stems and short oval capsule, like the normal form, but 

 no peristome, and therefore combine characters of both forms. 



2. B. Subulata, Bruch & Schimp. Plants in short com- 

 pact tufts ; stems slender : upper leaves more densely crowded, 

 erect-open, strict, rigid, glaucous-green when young, linear- 

 subulate and sharply serrate above the ovate half-clasping base ; 

 costa subpercurrent : flowers androgynous ; antheridia mixed 

 with the archegonia or separated by a single leaf only : capsule 

 on a strict short reddish pedicel, globose-ovate, marked from
