GILIA 



GILIA 



A. Plants not shrubby. (Nos. 1-17.) 

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



divided {lower lvs. sometimes opposite). 



c. Fls. in dense heads, which are subtended by leafy 



involucres. 



D. Foliage entire or at least not much parted. 



1. grandiflora, Gray (Collomia grandiflbra, Douglas). 



Fig. 1633. Erect, with minutely pubescent reddish sts. 



1634. Flower of Gilia 

 capitata. ( X2) 



1635. Gilia achille£efoli£ 



(Xk) 



1-2 ft. high: lvs. Unear-lanceolate or oblong, narrowed 

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

 dense terminal heads, buff or salmon-color, redder 

 inside, 1 in. long. Plains, west of Rocky Mts. B.M. 

 2894. B.R. 1174.— This and the next are interesting 

 annuals. Useful as bee plants. 



2. coccmea, Gray {Collomia cocclnea, Lehm.). More 

 slender: sts. not red: lvs. narrower (mostly linear), 

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

 low or buff outside and brick-red inside. Chile. B.R. 1622. 



DD. Foliage pinnately parted or compound. 



3. minima, Gray {Navarrctia mttnma, Nutt.). Dwarf 

 and tufted (3 in. or less high) often forming broad tufts, 

 nearly glabrous: lvs. needle-like, pinnately parted: 

 fls. white, the corolla scarcely exceeding the white- 

 hairy calyx. In arid districts. Dak. to Ore. and Colo. 



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

 spreading, tufted: lvs. mostly .3-7-divided into hnear 

 divisions: fls. corymbose or in close head-hke cymes; 

 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 Rocky Mts. to the Pacific. 



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



or if capitate, the heads not leafy-subtended. 



D. Plant perennial: seed only 1 in a locule: jls. small. 



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

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



sile, the purple corolla Min. long, the tube exceeding 

 the calyx. S. Utah. — Offered by collectors, but Uttle 

 known in cult. 



DD. Plant a?inual: seeds more than 1 to the locule: corolla 



distinctly tubular, but relatively small. 



E. Infl. capitate. 



6. capitata, DougW. Fig. 1634. Plant 18 in. to 2)4 

 ft. tall, the sts. long and nearly straight between joints: 

 fls. about J^in. long, in dense, nearly globular heads, 

 which terminate long, naked sts.; corolla-lobes lance- 

 hnear, acute: lvs. cut into very unequal hnear lobes. 

 Calif, and Ore. B.M. 2698. B.R. 1170. G.W. 1.5, p. 

 214. — An old favorite. There is a white form (var. 

 alba). There is also a var. major. 



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

 botanical characters, and possibly a form of it: lower 

 and much more slender, the If.-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 excel- 

 lent garden plant. 



EE. Infl. mixed, capitate on the main branches, scattered 

 on the others. 



8. achille&folia, Benth. Fig. 163.5. Stout (2-3 ft.) 

 and very branchy and bushy, the early main branches 

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

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

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

 the corolla-lobes oblong or obovate: caps, large. VV. 

 Calif. B.M. 5939 (showing only capitate infl.). — An 

 old garden plant. Fls. vary to white and rose, and 

 there is a large-fld. form. Various horticultural names 

 are in use for these forms, such as alba, rosea, major, etc. 



9. multica&lis, Benth. Not unlike the preceding, 

 from which it differs only in its smaller fls. and more 

 distinctive habit. Calif. B.M. 3440 and B.R. 1682, both 

 as G. achillesefolia from which this may not really 

 differ. 



EEE. Infl. scattered or loosely cymulose. 



10. tricolor, Benth. Fig. 16.36. A very diffuse, twiggy 

 grower, 2-2 ^'2 ft. high, sparsely pubescent: lvs. few on 

 the full-grown plant, small, with many short, very nar- 

 row or needle-shaped divisions: fls. comparatively 

 large {^iin. long or nearly so), nearly or quite bell- 

 shaped, the corolla 2-3 times the length of the calyx; 

 color of the roundish lobes violet and passing to whitish 

 at the base, of the throat 

 brown-purple and of the 

 tube yellow. W. Cahf. 

 B.M. 3463. B.R. 1704. 

 — One of the commonest 

 of garden annuals. 

 There is a white form 

 (G. nivalis, Hort. G. 

 dlba, Hort.), Gn. 72, p. 

 201, and a rose-colored 

 form {G. rosea, Hort.), 

 and a red-violet form 

 (var. rubro-violacen, 

 Hort.) Besides these 

 a small form has been 

 called G. nana, a large 

 one G. splendc7is, and 

 a dense, stiff one G. 

 compdcta . None of 

 these names appears to 

 be in anything but trade 

 catalogues. Thrives 

 with the least care, 

 and is always a pro- 

 fuse bloomer. It re- 

 quires an open warm 

 situation. . 1636. Gilia tricolor. ( X H)
