2. P. flmbriata, Banks; Sims & Keen. Ann. Bot. i. 391 (1805). 

 Leaves and scapes from thick branching rootstocks : leaves from reni- 

 form to cordate-ovate, 1 in. broad : scapes 1 ft. high, slender, bearing a 

 sessile leaf above the middle : petals obovate or oblong, narrowed to a 

 broad claw which is coarsely fringed on both margins : sterile filaments 

 completely united and forming a merely lobed carinate scale, or some- 

 times free above. — Has been found near Mt. Shasta, and also in the San 

 Bernardino Mountains : hence to be expected in the high Sierra within 

 our limits. 



10. CHRYSOSPLENIUM, Tournefort. Low fleshy glabrous herbs, 

 with petiolate crenate exstipulate leaves, and small axillary short-pedi- 

 celled greenish flowers. Calyx-tube adnate to the ovary ; lobes 4 or 5, 

 obtuse. Petals 0. Stamens 8 — 10, very short, on the margin of a disk. 

 Ovary 1-celled, 2-lobed above ; styles 2, short, recurved. Capsule com- 

 pressed, obcordate, 2-valved at top, with 2 parietal placentae, go -seeded. 



1. C. §rleelioinaefoliuiii, Nutt.; T. & G. Fl. i. 589 (1840). Stems slen- 

 der, depressed or ascending, rooting at the lower joints : leaves opposite, 

 or the upper alternate, roundish or ovate, abruptly cuneate at base 

 crenately dentate, 2—6 lines long, about equalling the petioles : fl. 1 — l}^, 

 lines long, exceeding the pedicels : seeds large for the plant, ovate, 

 In-own, shining. — In wet soil, Humboldt Co., Marshall, and northward. 



11. RIBES, Fuchs. Shrubs, with alternate palmately lobed often 

 resinous-glandular or viscid leaves ; the stipules when present adnate to 

 the petiole. Flowers racemose (rarely solitary) on short leafy shoots 

 from lateral buds ; pedicels subtended by a bract and usually bibracteo- 

 late about midway. Calyx-tube adnate to the globose ovary and more or 

 less produced above it, 5-lobed (4-lobed in n. 21), the lobes commonly 

 spreading or reflexed and usually colored. Petals 5, mostly smaller 

 than the calyx-lobes, inserted in or near the sinuses. Stamens as many 

 as the petals, alternate with them ; anthers short. Ovary 1-celled ; 

 placentae 2, parietal ; styles 2, more or less united ; stigmas terminal. 

 Fruit a berry, crowned with the withered remains of the flower. Seeds 

 with minute embryo in a firm albumen. 



* Unarmed; leaves convolute in bud; calyx-tube narrow and elongated. — 

 Genus Cheysobotrya, Spach. 



1. R. teimillorum, Liudl. Bot. Eeg. 1. 1274 (1829) ; Greene, Gard. and 

 Forest, iii. 198. Chrysobolrya Lindleyana, Spach, Phaner. vi. 151 (1838). 

 Shrub 5—10 ft. high, nearly glabrous, glandless : leaves light green,

 and conspicuous : fl. bright yellow, scentless ; calyx salverform, the tube 

 }^ in. long or more, thrice longer than the oval lobes : berry glabrous,
