■t- H— Flowers 5 (or exceptionally 6) -raerous : petals broader, usually exceeding the sepals : 

 nutlets about 2 lines long. 



F. Douglasii, Baillon. Glabrous, very spreading, the branches a span to a foot or more 

 long : divisions of leaves 3 to mostly about 9, from linear and entire to mostly lanceolate 

 and laciuiately once or twice cleft into narrow acute lobes : sepals narrow, acute : petals 

 yellow, white, or occasionally roseate near the end, rather narrow: nutlets from smooth to 

 strongly tuberculate. — Hist. PI. v. 20, f. 50-54; Greene, ¥1. Francis. 100. Limnanthes

 and L. sulphureus of gardens. — Oregon to Southern California. A low form 2 or 3 inches 

 high, with the petals scarcely eciualliiig the rather broad sepals, from Table Rock, Oregon, 

 Howell, 635, is L. intmila, Howell in herb. Tall ("aliforniau jjlants, a foot or more high, 

 often at first somewhat woolly as in F. alba, constitute F. versicolor, Greene, Erythea, 

 iii. 62. 



F. rosea, Gkekne. Glabrous, scarcely over a span high : divisions of leaves more linear 

 or tiliform, less incised : petals broader, whitish, marked by longitudinal roseate lines : iruit 

 very rough : otherwise like the last. — Fl. Francis. 100. Limnanthes rosea, Hartw. in Benth.

 Nortlieru Central California. 



F. alba, Greene. Low, rather erect and often subcorymbose : young parts and flower buds 

 very wliite-woolly with long hairs : leaf-segments about 7, narrowly lanceolate, commonly 

 entire except for the lowest pair which are 3-divided, but occasionally pinnatifid with about 

 5 ultimate segments: sepals relatively broad : petals yellowish white, often roseate or pur- 

 plish at top : nutlets prominently rugose-tuberculate. — Fl. Francis. 100. Limnanthes alba, 

 Hartw. in Benth. PI. Hartw. 301 ; Brew. & Wats. Bot. Calif, i. 95 ; Trelease, 1. c. 84. — 

 Oregon and the Sierras of California. Tall plants, a foot or more high, with the flowers 

 soon almost glabrous, have been collected in California, at Madera, Buckminster, Tunis Mill 

 and lone, Brandegee, and perhaps represent a state of F. versicolor, Greene, Erythea, iii. 

 62, which is held to be merely a transiently hairy form of F. Douglasii. 



6. OXALIS, L. Wood Sokrel. ('O^v's, sharp, from the acid taste.) — 

 Annual or perennial acid herbs sometimes woody at base, with compound petioled 

 leaves with entire or emargiuate leaflets, some species producing cleistogamous 

 flowers at base. — Gen. no. 377 ; Torr. & Gray, Fl. i. 210 ; Gray, Gen. 111. ii.

 in the temperate regions of the Old and New World. 



* Caulescent : flowers yellow, sometimes, like the rest of the plant, tinged with red-purple, 

 -t— Leaves unifoliolate, with free setaceous stipules : flowers homogone ? 

 O. dichondraefolia, Gray. A span to a foot high, appres-sed gray-villous throughout, 

 fruticose at base, the cespitose branches spreading : leaflet round-ovate, wavy-margined, 

 cordate, abruptly mucronate, 6 to 15 lines long, articulated at tlie summit of tlie often longer 

 petiole: flowers 6 lines long, solitary on axillary peduncles often exceeding the leaves, seta- 

 ceously bibracteate near the top : sepals auriculately cordate : petals narrow, clawed, about 

 twice as long as the calyx, rounded or mucronulate at apex : capsule round-ovoid, scarcely 

 as long as the sepals ; seeds about 3 in each cell, broad, about 1 line long, with prominent 

 tubercles somewhat obliquely confluent. — PI. Wright, i. 27, ii. 25 ; Torr. Bot. Mex. Bound.
