49. PTERIGYNANDRUM, Hedw. 

 iStcms with arcuate-prostrate somewhat fascicled slender branches, branching 

 irregularly. Leaves erect-spreading or subsecund, crowded, ovate or elliptical, short- 

 acuminate, concave, 1 - 2-nervcd at base ; areolation linear-flexuose, at the basal 

 angles quadrate, and rhombic above. Flowers dioecious. Calyptra cucullate. Cap- 

 sule long-pedicelled, erect, oblong. Peri.stome double, the inner processes short and 

 imperfect upon a very narrow basal membrane, without ciliolas. A single species. 



1. P. filiforme, Hedw. Small, loosely cespitose, greenish or yellowish : leaves 

 appressed when dry, papillose on the back, margins recurved, serrate at the apex, 

 sometimes 1-nerved to the middle : pedicel 9 lines long : capsule pale brown, nar- 

 rowly oblong ; operculum oblirpiely conic-rostrate : peristome small, pale yellow, 

 the inner very short and indistinct. — Muse. Frond, iv. 18, t. 7 ; Bruch & Schimp.

Var. Leaves cristate-serrate at the apex ; the stouter nerve ceasing above the 

 middle. — Leptohymenium cristatum, llampe, 1. c. 459; Lesip, 1. c, so refers it. 



On shaded rocks and tiros (Birjdojo, Bauer, Bolandcr) ; on the White Mountains and in Europe. 



Climaciiim, Wi'li. k Molir, is anotlior genus of this group of fasciculatoly bmnohcd mosses, 

 reaiUly distinguislied by its erect tree-like habit. C. A.meiucanum, Bri<l., of the Atlantic States 

 and aiso found in Oregon (//"//), is 2A or .3 inches high, with ovate-lanceolate leaves auricled at 

 base aiid costate nearly to the apex, serrate above, with minute elliptical areolation : capsule 

 cylindrical : peristome i)erfect, the processes on a very narrow membrane, equalling the teeth, 

 dehiscent, without cilioliK. — Sulliv. in Gray's Man. 2 ed. t. 5. 



50. ANOMODON, Hook, k Tayl. 

 On trees or rocks, the secondary branches ascending or erect, sj)aringly and irreg- 

 ularly or somewhat fasciculately branched. Leaves very densely rough papillose 

 on both sides, not complanate, costate, areolation minute or punctiform. Calyptra 

 naked. Capsule long-pedicellate. Peristome double, without cilioLx', the processes 

 shorter than the teeth. Otherwise as the preceding. 



About 6 or 8 species, mostly of North America and Einope, placeil in Uiipnum by Mueller. 



Lf.skf.a, IIe<lw., ns understood by Scliimper, is distinguished from Anommhm by its more 

 prostrate habit, the jjriniary stem leafy like the branches ; (lowers momvcious or dioecious. A 

 single species, L. poi.ycaupa, Ehrh., of the Atlantic States and Europe, which has been collected 

 in Oregon, Hall. Its stem is 2 inches long or more, with ascending branches 4 to 1 inch high : 

 leaves ovate-lanceolate, spreading or secund, margins recurved below, entire, the costa ceasing 

 below the apex : flowers monoecious : capsule (lylindrical, slightly curved : peristome whitish, the 

 processes eijualling the teeth. — Bruch k Schimp. Bryol. Eur. t. 470. 



1. A. Califomicum, Lesq. Loosely cesjiitose, brownish yellow, sparingly 

 branched, slender : leaves imbricated in 4 ranks, spreading when damp, broadly 

 ovate, half-clasjiing and decurrent, acute, the margin folded abruptly backward, 

 carinate with a stout costa ceasing at the apex, the papilhe upon the auricles longer 

 and spinose : fruit unknown. — Mem. Calif. Acad. i. 30.
