$ 2. LINANTHUS, Eudl. Corolla salverforra, the tube about equaling the cyliudric calyx-tube, the 
broad cuueate-obovate lobes usually minutely erose ; stamens included ; tilameuts slender, inserted 
uear the middle of the tube ; capsule cylindric or oblong ; cells 20-40-ovuled. Erect, slender, 
glabrous annuals; leaves opposite, filiforra, 3-5-divided or sometimes simple ; ilowers white, sub- 
sessile, terminal and in the forks ; calyx scarious except the elongated acerose-linear ribs. 
7. G. DiCHOTOMA, Benth. Corolla-lobes i-V long; anthers linear; seeds with a white finely reticu- 
lated non-mucilaginous coat. — California.

$ 3. LEPTOSIPHON, Endl. Corolla salverform with usually a long filiform tube and very short 
more or less cup-shaped throat, in which the stamens are inserted ; anthers short ; ovules 6-16 iu 
each cell. Low or slender annuals, with opposite narrow leaves and showy flowers in crowded 
bracteate clusters. 
' Hairy, leafy-sten)raed ; leaves palmately 5-7-parted, with linear-filiform lobes, commonly fascicled 
iu the axils ; corolla-lobes entire, exceeding the slender more or less exscrted filaments ; cells 
6-10-ovuled. 
(a.) Corolla large, the tube scarcely exceeding the obovate lobes and rarely the villous-hirsute 
bracts.

bracts and leaves very hirsute-ciliate ; calyx-lobes acerose. See page 264. 
" Eiit irt -lc;i \ (m1. glabrous, dwiirf; curolla-lobes cuneate, undulate-toothed or 1-3-deutate at the 
broad ap< x : ant hers sessile, included in the throat ; cells 10-16-ovxiled. 
14. G. xi'DK' vri.is. Clay. 1-4' high; stem naked, the capitate flowers bracteate with several ovate- 
lanceolate or lanceolate leaves ; corolla-tube 3-4" long, the lobes 2-3" long. See page 264. 
V^ 4. SIPHOXELLA, Gray. Like Leptosiplion, but the corolla-tube not exceeding the narrow calyx, 
the throat more funnelforra, the cells few-ovuled, and the flowers less crowded. Perennials, some- 
times woody at base, soft-puberuleut ; calyx firm, becoming 5-j)arted, the lance-subulate lobes with 
tliickisli luaigius, the sinuses not membranous uor scarious; corolla nearly Avhite, the tube puber- 
uli'iit, lolii's oliDvatc : filaments short, subexserted ; anthers oval-oblong. 
15. G. XniALLii, (iray. Stems numerous, slender, 6-12' high; leaves 3-7-iiartcd, narrow linear, 
mucroiiatt', usually shorter than the internodes ; flowers in leafj- clusters; ovules in pairs. See jiage 264 
and Plate XXV. 
16. G. Ki.oRim'XDA, Gray. 1- high or more; base more shrubby; leaflets nearly acicular, usually 
equaling the intern<i(lt's ; lldwt i s iu a rather loose corymbose cyme, sometimes pedicelled; cells 4-ovuled. — 
S. Caliloniia and Aiizoua. 
5. LEPTODACTYLON. lii utli. Corolla salverform, the tube at length exceeding the calyx, the 
throat somewhat funiielform : anthers short, ou short filaments inserted near the throat, included; 
ovules numerous; sei'd-eoat close, without uineilagc or spiricles. Tufted leafy sufiriitescent peren- 
nials; leaves alternate nv opposite, fascicled iu the axils, palmately 3-7-parted, the entire segments 
and the calyx-lobes ae<'rose or subtilate. luuigent ; flowers sessile, solitary upon the sliort branch- 
lets or in few-flowered terminal clusters. 
* Leaves opposite ; stems short, herbaceous. 
17. G. iny. 4-6' high; leaves not much fascicled; corolla-tube and lobe each long ; 
cells 10-ovul< .:, -e 265 and Plate XX VI.
