GILIA 



GILIA 



643 



volucellate ; calyx partly herbaceous, scarious below 

 the sinuses; lobes narrow and acute ; corolla salver- 

 form or funnel-form to campanulate or almost rotate ; 



902. Gilia grandiflora (X %). 



filaments not bearded at base : seeds wingless : herbs, 

 or a few suffruticose." 



Several of the Gilias are popular garden annuals or 

 biennials (a few perennial). They are of the easiest 

 culture, being vigorous, hardy and floriferous. They 

 are mostly dwarfish, and are excellent for low masses, 

 edgings or rockeries. Seeds may be sown where the 

 plants are to grow. Any good soil will suit them.

A. Lvs. normally alternate, entire or pinnately cut or 



divided (lower Ivs. sometimes opposite). 



B. Fls. in dense heads, which are subtended l>y leafy 



involucres. 

 c. Foliage entire or at least not much parted. 



1. grandifldra, Gray (Collbmia grandifldra,Dougl.). 

 Fig. 902. Erect, with minutely pubescent reddish stems, 



-2 ft. high: Ivs. linear-lanceolate or oblong, narrowed 

 below but scarcely petioled, entire, acute : fls. many, in 

 dense terminal heads, buff or salmon color, redder in- 

 side, 1 in. long. Plains, W. of Eocky Mts. B.M. 2894. 

 B.R. 14:1174. This and the next are interesting an- 

 nuals. Useful as bee plants. 



2. coccinea, Gray (Collbmia coccinea, Lehm.). More 

 slender: stems not red: Ivs. narrower (mostly linear), 

 somewhat cut at the ends: fls. smaller, slender-tubed, 

 yellow or buff outside and brick-red inside. Chile. B.R. 

 19:1622. 



CO. Foliage pinnately parted or compound. 



3. minima, Gray (Navarretia minima, Nutt.). Dwarf 

 and tufted (3 in. or less high), nearly glabrous : Ivs. 

 n'eedle-like, pinnately parted : fls. white, the corolla 

 scarcely exceeding the white-hairy calyx. In arid dis- 

 tricts, Dak. W. 



4. eongesta, Hook. A foot or less high, erect or 

 spreading, tufted : Ivs. mostly 3-7-divided into linear 

 divisions: corolla white, the oval lobes nearly as long as 

 the tube: calyx teeth long-pointed, nearly equaling the 

 corolla. A small-fld. species growing from Wyo. W. 



BB. Fls. not in close heads, but more or less scattered: 



or if capitate, the heads not leafy -subtended. 



c. Plant perennial: seed only 1 in a locule : fls. 



small. 



5. debilis, Wats. Two in. or less high : Ivs. oblong, 

 entire or 2-3-lobed, petioled : fls. solitary and nearly ses- 

 sile, the purple corolla % in. long, the tube exceeding 

 the calyx. S. Utah. Offered by collectors. 



CC. Plant annual: seeds more than 1 to the locule: 



corolla distinctly tubular, but relatively small. 



D. Inflorescence capitate. 



6. capitata, Dougl. Fig. 903. Plant 18 in. to 2% ft. 

 tall, the stems long and nearly straight between joints: 

 fls. about %in. long, in dense, nearly globular heads, 

 which terminate long, naked stems; corolla lobes lance- 

 linear, acute : Ivs. cut into very unequal linear lobes. 

 Calif, and Ore. B.M. 2698. B.R. 14: 1170. -An old fa- 

 vorite. There is a white form (var. alba). There is 

 also a var. major. 



7. laciniata, Ruiz & Pav. Much like the last in 

 botanical characters, and possibly a form of it ; lower 

 and much more slender, the leaf -divisions mostly very 

 narrow (usually almost thread-like), the heads smaller 

 or the fls. sometimes even scattered. Chile. The fine 

 foliage and compact habit make this species an excellent 

 garden plant. 



DD. Inflorescence mixed, capitate on the main branches, 

 scattered on the others. 



8. achilleaefdlia, Benth. Fig. 904. Stout (2-3 ft.) and 

 very branchy and bushy, the early main branches ter- 

 minating in large, dense heads, but the later, finer 

 growth bearing scattered fls. : Ivs. small, with short, 

 linear lobes or teeth: fls. large, violet or purple-blue, 



903. Flower of Gilia capitata. 

 <X2.) 



904. Qilia achillearfolia.
