 and more papillose leaves : male flowers discoid : capsule ovate-oblong, somewhat 

 incurved. Suppl. t. 226 ; Bruch & Schimp. 1. c., t. 405 ; Wilson, 1. c. ; Berkeley,

38. BARTRAMIA, Hedw. 



Cespitose perennials, on the ground or rocks, innovating at the apex and branching 

 dichotomously or subverticillately ; stems erect, tomentose. Leaves mostly dull 

 glaucous-green, lanceolate and often elongated from a subclasping base, papillose 

 both sides, serrate and costa excurrent ; areolation minutely quadrate above. In- 

 florescence various. Calyptra small, cucullate, smooth, fugaceous. Capsule globose 

 or nearly so, usually cernuous on a long straight solitary pedicel (sometimes short 

 and curved), striate and sulcate when dry, with minute convex-conic operculum and 

 no annulus. Peristome rarely single or wanting, usually double as in Brynm, the 

 inner teeth upon a short basal membrane, cleft to the base, segments at length diver- 

 gent ; cilioke often present. Sporangium much smaller than the cavity, stipitate. 



A genns of nearly 100 species, largely South American, rather sparingly represented in Europe 

 and North America. Besides the following, four other species are found in the Atlantic States. 

 The section Philonotis is retained as a genus by Schimper. 



* Stem dicJwtomous, the branches not fascicled : leaves narrowed from the base, 

 setaceous : male flowers bud-like. BARTRAMIA proper. 



- Capsule erect, symmetrical : peristome simple or rudimentary. 



1. B. stricta, Brid. Leaves erect-spreading, strict, rigid and fragile when dry, 

 lanceolate-subulate, minutely serrate, spinulose-awned, rough both sides : flowers 

 bisexual : capsule ovate-globose upon a strict pedicel ; operculum convex or mamil- 

 late : teeth saffron-colored, regular and entire, or sometimes irregular, erose on the 

 margin and dehiscent. Bruch & Schimp. Bryol. Eur. t. 316; Sulliv. & Lesq. 

 Muse. Am.-Bor. Exsicc. 2 ed. n. 256. 



On moist rocks and ground near San Francisco (Bolandcr) ; Europe. Pedicels terete ; Schimper 

 describes the pedicels in the European form as obtusely tetragonal. 



2. B. Menziesii, Hook. Broadly and loosely cespitose, bright green above; 

 stems 2 or 3 inches high or more, simple or sparingly branched, brown-tomentose to 

 beyond the middle : leaves appressed or somewhat spreading, lanceolate-subulate 

 from an ovate base with reflexed margins, serrate, scabrous on the back of the stout 

 excurrent costa : flowers dioecious : pedicels lateral by innovation, \ of an inch long, 

 erect : capsule broadly ovate, pale red ; operculum conic, obtuse : teeth lanceolate, 

 irregularly jointed, sometimes rudimentary. Muse. Exot. t. 67 ; Schwaegr. Suppl. 

 t. 240 ; Sulliv. & Lesq. 1. c., n. 259, 260 ; Sulliv. Icon. Muse. Suppl. 39, t. 26. 

 Glyphocarpa Baueri, Hampe, Linnaja, xxx. 457. 



On shaded rocks, common ; first collected by Men~iex. A form occurs on dry rocks (Bauer, 

 Bolander) with slightly shorter leaves and somewhat longer capsule, the peristome usually want- 

 ing or marked by a thin more or less irregularly lacerated membrane.
