filaments not bearded at base : seeds wingless : herbs, 

 or a few suffniticose." 



Several of the Gilias are popular garden annuals or 

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

 culture, being vigorous, bai'dy and floriferous. They 

 are mostly dwarfish, and are excellent for low masses, 

 •■^dgings or rockeries. Seeds may be sown where the 

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

divided [lower h\s. simiefimes opposite). 



B. FJs. in dense heads, which are subtended hi/ h'ufji 



in volaeres . 

 c. Foliage entire or at least not much parted. 



1. grandiflora. Gray [CoJlbmia grandi flora. Dougl.). 

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

 1-2 ft. high; lvs. linear-hiuceolate or oblong, narrowed 

 below but scarcely peticded, entire, acute: lis. many, in 

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

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

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

 nuals. Useful as bee plants. 



2. cocclnea, Gray {Colli>mia roceiitcu ,'Liii^\\\w.) . More 

 slender: stems not red: lvs. narrower (mostly linear}, 

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

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

 19:1622. 



CC. Foliage pinnatehj parted or compound. 



3. minima.. Gray {jVavarref i a minima , Nutt.) . Dwarf 

 and tufted (3 in. or less high), nearly glabrous ; lvs. 

 needle-like, pinnately parted : tis. white, the corolla 

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

 tricts, Dak. W. 



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

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

 divisions: corolla white, the oval lobe.s nearly as long as 

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

 corolla. A smaJl-tid. species growing from Wyo. W. 



BB. Fls. not in c/o.sw heads, hut more or les.s scattered : 



or if capitate, the heads -not lea fi/suh/cnded. 

 '■. Plant perciiuial : seed on I if I in it locale : fls. 

 small. 

 '). d^bilia, Wats. Two in. or less high : lvs. oblong, 

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

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

 the calyx. 8. Utah. — Offered by collectors. 



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

 corolla distinctly tubular, but relatively small. 

 1). Inflorescence cajntate. 

 G. capitata, Dougl. Fig. 90.3. Plant 18 in. to 2?o ft. 

 tall, the stems long and nearly straight lietween joints: 

 tls. about /oiu. long, in <lense, nearly globular heads, 

 which terminate long, naked stems; corolla lubes lunce- 

 iinear, acute : lvs. cut into very unequal linear lobes. 

 Calif, and Ore. B.M. 2(;98. B.R. 14:1170. -An old fa- 

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

 also a var. major. 



7. lacini^ta, 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. sometiiues even scattered. Chile. — The tine 

 foliage and compact habit make this species an excellent 

 garden plant. 



DD. Inflorescence mixed, capitate on the main branches, 

 scattered on the others. 



8. achilleeefdlia, 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
