Near Oakland and elsewhere, common (Bigclow, Bolander) ; the variety in Dardanelles Canon 

 {Bolander) ; Europe and Northern Africa. 



9. G. Californica, Sulliv. Loosely cespitose, about J inch high : leaves erect- 

 spreading, long-lanceolate, carinate, concave with revolute margin, costa excurrent 

 into a hyaline denticulate hair : calyptra cucullate-mitriform, 4 - 5-cleft at base : 

 capsule oval or oblong, with an evident collum, pendulous upon a short arcuate 

 pedicel, scarcely costate when dry ; operculum with a long straight beak ; annulus 

 rather broad, compound : teeth bifid nearly to the middle. Pacif. R. Rep. iv. 187, 

 t. 4, excl. var. ; Sulliv. & Lesq. 1. c., n. 205, 206. 



On rocks at San Rafael and around San Francisco, common, Bigeloic, Bolander. With it is

 longer operculum. 



10. G-. hamulosa, Lesq. Loosely tufted, blackish : leaves somewhat fascicled, 

 falcate-secund when dry, erect and curved inward like a hook when moist, loosely 

 imbricated, narrowly lanceolate-subulate, carinate-concave with nearly flat margin,

 curved pedicel, oval, smooth, brown, with a short conic operculum and no annulus : 

 teeth rather short, lacerate or imperfectly divided. Mem. Calif. Acad. i. 14. 



On gravelly soil upon Mount Dana, at 10,000 feet altitude, Bolander. 



4. Capsule upon a straight erect pedicel, mostly exserted, not ribbed ; coluw.ella 

 not deciduous : leaves spreading, not crisped, mostly setose, with flat 

 margins; areolation rectangular at base, rarely sinuous. GUEMBELIA. 



* Calyptra mitriform, lobed at base. 

 j- Flowers monoecious. 



11. G. ovata, Web. & Mohr. Rather stout, tufted, J inch high or more, 

 green turning gray : leaves lanceolate from an oblong concave base, with reflexed
