POTENTILLA SAXOSA Lemmon. 



"Perennial, slender, a foot high, pu- 

 bescent and viscid-glandular: leaves 

 narrow, pinnate, the leaflets in 5-7 

 pairs, flabelliform, % inch long or less, 

 and quite as broad, pedately cleft to 

 the middle into -oblong acutish seg- 

 ments: cymes loose, flowers small and 

 inconspicuous; calyx rotate, the seg- 

 ments scarcely 2 lines long; stamens 

 25-30; filaments slender-subulate; an- 

 thers roundish, rather broader than 

 long: pistils 8-10. Crevices of rocks, in 

 the San Rafael mountains, Lower Cal- 

 ifornia, 6 May, 1888, Mr. and Mrs. Lem- 

 mon." Greene, Pittonia 1:171. 

 PARNASSIA CIRRATA Piper. 



"Erect, 3-4 dm high, glabrous 

 throughout; radical leaves ovate, ob- 

 tuse, palmately 5-veined, 1-2 cm long, 

 cuneate at base but not at all reni- 

 form; petioles 4-5 cm long with a few 

 fimbriae on the margin of the dilated 

 base; cauline leaf very small, about 

 6 mm long, lance-ovate, obtuse, sessile: 

 fl 2-2.5 cm in diameter: sepals lanceo- 

 late, obtuse, 7 mm long; petals oblong- 

 obovate, 1 cm long, the lower half mar- 

 gined with fimbriae longer than the 

 width of the petal: staminodia 5, as 

 broad as the petals, 2 mm long, cleft 

 half way into about 12 equal, filiform, 

 gland-tipped appendages: capsule 

 ovoid, 1 cm long. Mt. San Bernardino,

 TELLIMA TRIPARTITA Greene. 



"Very slender, less than a foot high, 

 hispidulous under a lens, in no part 

 glandular: radical leaves rather nu- 

 merous, small, about % inch broad, 

 parted almost to the base into 3 obo- 

 vate-spatulate or obcordate lobes; the 

 cauline solitary, similar to the radical: 

 flowers only 3-6, in a loose raceme, the 

 pedicels about equalling the calyx; this 

 campanulate, nearly free from the 

 ovary, the lobes triangular, acute: pet- 

 als rather large, pinkish, 3-lobed, the 

 2 upper ones less distinctly so, or en- 

 tire." Greene, Erythea 1:106. Near

 simple below, parted above into numer- 

 ous dichotomous somewhat flexu-ous 

 branches; glabrous except a scant pu- 



bescence on the flower buds: leaves 

 narrowly linear, %-l in. long: corolla 

 .P/ lines broad, rose-color changing to 

 rose-purplish: capsules linear-oblong, 

 on capillary erect pedicels, few-seeded, 

 torulose: seeds canescent with an ap- 

 pressed silky pubescence. Near Julian,

OENOTHERA RUTILA Davidson. 



"Annual, stoutish, erect, 6-8 inches 

 high, glabrous except the younger 

 leaves and the inflorescence which are 

 sparingly pubescent; leaves ovate-lan- 

 ceolate, narrowed to the petiole, re- 

 motely denticulate in the upper half; 

 floral leaves similar but smaller: spike 

 slightly nodding, many-fl'd, becoming 

 much elongated: calyx-tube 2 lines 

 long: petals as long ovate, reddish: 

 capsules 8 lines long, obtusely angled, 

 appressed to the stem, attenuate to the 

 narrow apex, curving outwards, puber- 

 ulent, not contorted; seeds dark and 

 angled." Davidson, Erythea 2:62. Mo-

"Annual, branching from the base, 

 stout, a foot high or less, white-cau-

 lower attenuate to a short petiole, the 

 rest .sessile and mostly cordate-am- 

 plexicaul at base: fls terminal, solitary 

 and sessile, involucrate with a pair of 

 very broadly ovate acute or acuminate 

 scarious bracts, the green margin 

 coarsely toothed: petals pale yellow, 

 an inch long, oblanceolate and cuspi- 

 dately acuminate; stamens very nu- 

 merous and slender, 3-6 lines long, the 

 outer dilated above and continued into 

 a long linear cusp on each side of the 

 anther: .style tubular, equalling the 

 longer stamens, with 3 flattened stig- 

 matic lobes at the summit: capsule 

 about 9 lines long by 3 or 4 broad at
