 tnbe i' long ; anthers included on very sbort filaments. See page 269. 



§ 10. GILIANDRA, Gray. Thyrsoid-panicled and resembling § Ipomopsis, but the white or bluish 

 corolla ealverforra, the tube about twice longer than the calyx and little exceeding the obovate 

 lobes ; filaments exserted beyond the corolla ; anthers ovate ; cells 6-8-ovuled ; seeds without 

 mucilage or spiricles. Glandular-puberulent biennials, with simply pinnatifid leaves and rather 

 small flowers. 



46. G. STENOTHYRSA, Gray. Stem stout, simple, very leafy, with a virgate thyrsus ; leaf-lobes short, 

 oblong, the floral leaves small and entire ; corolla y long, white. See page 269. 



47. G. PINNATIFIDA, Nutt. 9-18' high, glabrate below; leaf-segments linear or narrow-oblong, 

 sometimes 1-2-lobed ; panicle compound, loosely branched ; bracts linear or subulate, few ; corolla blue 

 or purplish, the tube and lobes each usually 3" long; stamens 3" long. — Northern New Mexico, Colorado,

§ 11. MICEOGILIA, Benth. Flowers very small, scattered along the slender branches in loose 

 spikes or panicles ; calyx short-campannlate, 5-toothed ; corolla white, salverform, the tube a 

 little exserted and slightly exceeding the lobes; stamens inserted on the tube, included ; anthers 

 very short ; ovules solitary. Much-branched subglabrous annuals, with small filiform or slender 

 subulate leaves.entire or the cauline 3-parted. 



48. G. MiNUTii'XORA, Benth. Glabrous or glandular-puberulent above, 1-2° high, rather rigid ; 

 upper leaves reduced to minute scattered bracts ; flowers terminal or often spicate along the strict 

 branehlets ; calyx-teeth short, ovate-subulate, half as long as the narrow tube of the (scarcely 2" long) 

 corolla ; filaments slender ; capsule ellipsoidal, 2" long ; seed oblong. — Colorado and Central Oregon. 



49. G. TENEKRIMA, Gray. 1J° high, glabrous; flowers loosely panicled, scattered on the slender 

 branehlets ; leaves entire ; calyx-teeth ovate, nearly equaling the globose capsules ; seed ovoid. See 

 page 270. 



5 12. EUGILIA, Benth. Flowers panicled, capitate-clustered or more frequently scattered ; bracts 

 small or none; corolla purple, blue or white, funnelform, or nearly oampanulate or rotate; fila- 

 ments slender, in or near the sinuses, rarely exceeding the corolla; cells few-mauy-ovuled . 

 Mostly annuals, with incised or 2-3-pmnat6ly divided leaves. 



■• Flowers in a long-peduncled head-like cyme ; corolla mostly blue, funnelform, its tubes equaling 

 the lobes and not exserted ; stamens at the sinuses ; ovules rather numerous. Erect annuals, 1-3° 

 high ; leaves 2-3-piunately divided, the segments very narrow. 



50. G. CAPITA TA, Dougl. Slightly pubescent or nearly glabrous, as is usually the calyx ; corolla-lobes 

 linear-lanceolate, nearly equaling the slightly dilated tube.— Oregon and California. 



51. G. ACHiLHt^FOLiA, Benth. Glabrous with slight deciduous wool, or glandular; flowers larger ; 

 calyx more or less woolly, th'i lobes shoit-mucronate; corolla-lobts obovate or broad-oblong, the 

 throat abruptly and widely dilated. — California. 



• * Flowers rather crowded or in the latter species loosely panicled or scattered ; corolla funnel- 

 form, with a more or less dilated throat ; stamens inserted at or near the sinuses; ovules many 

 Low sometimes di6fuse annuals, pubescent or glabrate ; mostly Californian. 



52. G. MULTlCAULis, Beuth. Leaves mostly bipinnatifid with narrow-linear segments ; flowers clus- 

 tered, (often solitary in Var. tenkra,) terminating a slender peduncle, subsessile; calyx viscid, the tube 

 twice longer than the teeth ; corolla violet, the proper tube shorter than the calyx, the obovate or ovate 

 lobes not exceeding the funnelform throat ; capsule ovoid. 



53. G. TRICOLOR, Benth. Diffuse; leaves 2-3-pinnatifid with linear or nearly filiform segments; 

 flowers corymbed or clustered on rather short terminal peduncles, the pedicels shorter than the visoid- 

 pnberulent or rarely glabrous calyx ; corolla-tube very short, the ample campanulate-funnelform throat 

 yeUow or orange below and deep-purple above, the roundish lilac or violet lobes exceeding the stamens. 



54. G. TENUIFLOKA, Benth. Slender; lowest leaves bipinnately parted or incised with short seg- 

 ments, or sometimes simply pinnatifid ; flowers loosely panicled on slender pedicels; corolla purple or
