Flowers large, scarlet. Fuchsia-like. Calyx above the ovary colored like 
the corolla, the tube appendaged within with scales. Petals inserted on 
throat of the calyx. Stamens exserted, colored like the corolla. Style 
long-exserted. (M. Zauschner, a Bohemian botanist, one time Professor 
of Natural Histor)' in the University of Prag.) 
1. Z. californica Presl. Balsamea. Leaves oblong to lanceolate or 
narrowly linear; flowers 3.6 to 4.8 cm. long.—Dry stream beds and rocky 
mountain sides. A decoction of the foliage and also the powdered leaves 
are used for cuts and bruises in horses. 
2. EPILOBIUM L. Willow Herb 
Annual or perennial by creeping rootstocks, or by offsets. Leaves 
usually opposite. Flowers purple, rose-color or white in racemes. Sta¬ 
mens 8, the 4 alternate shorter. Ovary long and narrow. (Greek epi, 
upon, lobus, a pod, and ion, a violet.) 
Petals 10 to 14 mm. long, entire; capsule 5.1 to 7.6 cm. long....l. E. angustifoliurn. 
Petals 6 to 8 mm. long, emarginate; capsule 2.5 cm. long.2. E. paniculatum. 
1. E. angustifoliurn L. Fire-Weed. Stems simple, erect from a 
stout root, 8 to 23 dm. high, canescent above: leaves glabrous, pale be¬ 
low, lance-linear to lanceolate; inflorescence many-flowered, with bracts; 
petals spreading, purple.—In moist or boggy ground especially in fire- 
swept areas. 
2. E. paniculatum Nutt. Stem simple below, paniculately branched 
above, 4 to 14 dm. high; bark exfoliating; herbage glabrous with inflores¬ 
cence more or less glandular; leaves lanceolate to linear; racemes few- 
flowered; petals ascending, purplish.—Dry ground. 
3. CLARKIA Pursh 
Annuals with brittle stems and alternate leaves. Flowers showy, in a 
terminal raceme, nodding in the bud. Petals purple or rose-color, clawed. 
Stamens 8, or 4 rudimentary or wanting. Capsule straight or some¬ 
what curved, coriaceous, somewhat 4-angled. (Captain Clarke of the 
Lewis & Clarke party, first expedition across the Rocky Mts. to the 
Pacific, 1806.) 
Petals entire ; calyx-tube above the ovary obconical, 2 to 4 mm. long; stamens 8. 
Claw much shorter than limb of petal, often toothed.1. C. rhomboidect. 
Claw about as long as limb of petal, not toothed.2. C. elegans. 
Petals lobed; calyx-tube above the ovary almost filiform, 1.9 to 3.2 cm. long; 
stamens 4 .-.3. C. concinna . 
1. C. rhomboidea Dough Erect, 2.8 to 8.6 dm. high; petals rose- 
purple, often purple-dotted toward the base, rhomboidal, 6 to 18 mm. long, 
the claw short and broad; filaments with whitish hairy scales at base.— 
Foothills and mountains. 
2. C. elegans Dough Similar to no. 1; claw of petals about as long 
as limb, not toothed.—Foothills and mountains. 
3. C. concinna’ (F. & M.) Greene. Red Ribbons. Simple or diffusely 
branched, 1.5 to 4 dm. high; petals cuneate-obovate, 3-lobed, 1.2 to 2.4 
cm. long.—Mountain ranges at middle altitudes. 
4. GODETIA Spach 
Erect annuals. Flowers in leafy racemes or spikes. Calyx-tube above
