213 ONAGRACE^. Zauschneria. 



4 erect and 4 deflexed. Petals 4, inserted on the throat of the calyx and rather 

 shorter than its lobes, ohcordate or 2-cleft, scarlet. Stamens 8, exserted ; the fila- 

 ments opposite to the petals shorter ; anthers linear-oblong, attached by the middle. 

 Ovary 4-celled : style long and exserted : stigma capitate or peltate, 4-lobed. Cap- 

 sule linear, obtusely 4-angled, 4-valved and imperfectly 4-celled, many-seeded. 

 Seeds oblong, with a tuft of hairs at the apex. — Low decumbent perennial, some- 

 what woody at base ; leaves sessile (the lower opposite) ; the large scarlet Fuchsia- 

 like flowers in a loose spike. A single variable species. 



1. Z. Californica, Presl. More or less villous and often tomentose, much 

 branched, the ascending or decumbent stems a foot or two long : leaves narrowly 

 lanceolate to ovate, | to 1| inches long, acute, entire or denticulate : flowers 10 to 

 16 lines long above the ovary; the calyx-lobes 4 luies long : capsule attenuate to 

 the slender base, h to 1 inch long, sometimes shortly pedicellate. — Eel. Haenk. ii. 

 28, t. 52; r.ot. :\lag. t. 4493. Z. Mexicana, Presl, 1. c, ii. 29. 



Var. microphylla, ( !ray in herb. Pubescence tomentose, scarcely or not at all 

 villous : leaves linear, often very small (3 to 4 lines long), lascicled in the axils. 



In dry localities from Napa and Plumas counties to S. California and Northern Mexico, and 

 eastward of the Great Basin from N. W. Wyoming (Parry) to the Wahsatch ( Watson) and New 

 Mexico ( IFrirjhf) ; the variety in S. California. Very variable in its foliage and puTjescence, and 

 in its flowers, which are broadly or narrowly funnelform, more or less deeply colored, and with 

 the style and stamens more or less exserted. 



4. EPILOBIUM, Linn. Wili.ow-Herb. (ByW. Barbey.) 



Tube of the calyx not conspicuously prolonged beyond the ovary ; the limb 



deeply 4-cleft, campanulate or funnelform, or 4-parted to the base with the lobes 



spreading, deciduous. Petals 4, spreading or somewhat erect. Stamens 8, the 4 



alternate ones shorter; anthers elliptical or roundish, fixed near the middle. Stigma 



oblong, clavate, or with 4 spreading or revolute lobes. Capsule linear, 4-sided, 



4-celled, 4-valved. Seeds numerous, ascending ; the summit furnished with a coma or 



tuft of long hairs. — Perennial or annual herbs ; leaves alternate or opposite, nearly 



sessile, denticulate or entire, often fascicled ; flowers rose-colored, purple or white, 



very rarely yellow. 



A genus of about 100 species, inhabiting the temperate and colder regions of the globe, many 

 of them very variable, and the number greatly multiplied by authors. 



* Flowers large : stamens and style declined : stigma-lohes spreading : peirjinicd. 



1. E. spicatum, Lam. Stem erect, simple, often 4 to 7 feet high, mostly 

 glabrous : leaves scattered, lanceolate, sessile, nearly entire, the veins anastomosed 

 near the edge : flowers in a long spicate raceme, bracteate, purplish lilac : limb of 

 the calyx nearly 4-parted, often colored, spreading : petals obovate, unguiculate, 

 si)reading : stamens purple : style yellow, hairy at the base, at first deflexed ; stigma- 

 lobes linear : capsule canescent. ■ — ■ B. angustifolium, Linn. 



In the Sierra Nevada {Bridgcfi) ; northward to Behring Straits and eastward across the con- 

 tinent. Also in Europe and Asia. 



2. E. obcordatum, Gray. Roots diftuse : stems branching from the base, 

 decumbent, 3 to 5 inches long, 1 - 5-flowered, glabrous throughout : leaves opposite, 

 ovate, sessile, numerous, mostly longer than the internodes (4 to 8 lines long), 

 glaucous, opaque : flower-buds of somewhat irregular shape : calyx-limb 4-cleft, the 

 lobes of irregular width : petals obcordately 2-lobed, spreading, of a bright rose-color, 

 half an inch long : stamens yellow, shorter than the purple declinate style : stigma
