GILIA 



GILLENIA 



1337 



DDD. Plant biennial: seeds few or many in each locule: 



fls. large and long-tubular, red (running into 



white forms), the corolla very much surpassing 



the subulate calyx-lobes. (Ipomopsis.) 



11. coronopifdlia, Pers. (Ipomopsis elegans, Poir. 



/. aurantlaca and /. sanguinea, Hort.). STANDING 



CYPRESS. St. strict and unbranched, sometimes 6 ft. 



high, very leafy: Ivs. pinnate, the divisions needle-like 



and about -1 in. long: fls. many, l l /z in- long, long- 



1637. Gilia liniflora. (X%) 



1638. Gilia micrantha. ( X M) 



trumpet-shape, borne along the sides of the summit of 

 the st., the calyx inconspicuous amongst the short 

 bract-lvs., the corolla scarlet or pink-red and dotted 

 and yellowish within, varying to orange, its lobes obtuse 

 or nearly so and flaring. In dry soil, S. C., south and 

 west. B.R.1691. G.C.III.40:277. G.M. 49:598. Gn.70, 

 p. 165. Common old garden plant, and worthy. Fls. 

 scentless. Name should probably be G. rubra, Heller. 



12. aggregata, Spreng. (Ipomopsis elegans, Lindl.). 

 Differs in mostly shorter stature, pubescent st., and 

 more slender habit, with redder (sometimes white) 

 fragrant fls., with acute and reflexing corolla-lobes. 

 Neb., south and west. B.R. 1281. The fls. are fiery 

 scarlet or sometimes nearly white. A very showy 

 biennial. 



BB. Lvs. opposite, entire, or, if alternate (as in No. 13) 



palmately parted. 

 c. Foliage very fine, the Ivs. cut into thread-like or linear 



divisions. 

 D. Corolla rotate-bell-shape, with a short, flaring tube. 



13. linifldra, Benth. (G. linifolia, Hort.). Fig. 1637. 

 Ten to 20 in. high, diffuse and branchy: lower Ivs. 

 mostly opposite, but the upper alternate, all palmately 

 divided to the base in needle-like or spurrey-like 

 divisions: fls. rather large for the size of the plant, the 

 corolla white or blush, 



nearly rotate, the thin 

 lobes obtuse. Calif. B. 

 M. 5895. A useful tufty 

 garden annual. The 

 name liniflora is meant 

 to designate the resem- 

 blance of the fls. to those 

 of Linum tenuifolium; 

 but some catalogue- 

 maker, evidently think- 

 ing that the name meant 

 linear-flowered, and was 

 therefore inappropriate or an error, has changed the 

 name to G. linifolia, under which name it is known in 

 the trade. 



DD. Corolla salverform, with a filiform and elongated 

 tube. (Leptosiphon.) 



14. densiflora, Benth. (Leptosiphon densiflorus, 

 Benth.). Erect or even strict, 1-2 ft., hairy: Ivs. with 

 many filiform somewhat rigid divisions: fls. in rather 



1639. Gilia dianthoides, the 

 Fenzlia of gardens. 



close heads, lilac or white, H~M in. long; tube of the 

 corolla scarcely longer than the Ivs.; lobes of the 

 corolla spreading, obtuse, often dentate, nearly or quite 

 as long as the tube. Calif. B.M. 3578. B.R. 1725. 

 Common garden annual. The white-fld. form is known 

 as var. alba, Hort. 



15. androsacea, Steud. (Leptosiphon androsaceus, 

 Benth.). Much like the last, but the tube very slender 

 and much exserted beyond the calyx and Ivs.: fls. 1 

 in. long, pink, lilac or white, in rather close heads, the 

 corolla-lobes ovate-acute and entire, much shorter 

 than the tube, 12-18 in. Calif. B.M. 3491. B.R. 1710. 



16. micrantha, Steud. Fig. 1638. Tufted, 8 in. or less 

 high, the sts. most leafy near the top: Ivs. short, fas- 

 cicled: fls. with an exceedingly slender thread-like tube 

 which is 1-1 ^2 in. long, and projecting prominently 

 above the upper fascicles of Ivs., the corolla-lobes 

 spreading and obtuse; color range very wide, from 

 purple to lilac, red, yellow and white. Calif. A popu- 

 lar bedding plant. Forms of it are known as Leptosiphon 

 aureus, L. carmineus, L. hybridus, and L. roseus. 



cc. Foliage of entire (but narrow) Ivs. 



17. dianthoides, Endl. (Fenzlia dianthiflora, Benth.). 

 Fig. 1639. Tufted, 6 in. or less high: Ivs. narrowly lin- 

 ear, opposite: fls. 1-1 M in- long, lilac or purple, with 

 yellowish throat, the flat-spreading lobes denticulate or 

 nearly fringed. S.Calif. B.M. 4876. R.H. 1865:11. 

 A choice little annual, excellent for edgings and rock- 

 work, bearing a profusion of pink-like fls. The fls. 

 sometimes vary to white (Fenzlia alba, Hort.). A 

 large-fld. form is called G. speciosa. 



AA. Plants shrubby. 



18. californica, Benth. A low, procumbent and 

 much-branched shrub: Ivs. alternate, deeply digitately 

 parted into 5-7 stiff and hairy segms: fls. showy, very 

 free; sepals subulate, mucronate; petals cuneate, some- 

 times toothed, rose-colored. Calif. B.M. 4872. A fine 

 showy species, perhaps not hardy in the E. 



G. abrotanifdlia, Nutt., occurs in mountains back of Santa 

 Barbara, and has been listed in collections of native plants for sale: 

 1-2 ft., simple or somewhat branched: Ivs. ample, all tripinnately 

 dissected, the ultimate segms. very narrow and acute and curved 

 backward: fl. without markings (blue?), large, the lobes spread- 

 ing, obovate and obtuse; stamens scarcely protruding. G. Chamis- 

 sdnis, Greene, is a segregate from G. achiltefolia: annual, but some- 

 times persisting over winter, 1 ft.: Ivs. mostly twice pinnately dis- 

 sected into linear segms. : branches few and peduncle-like, bearing 

 large and dense heads of blue fls. Calif. T IT B 



N. TAYLOR, f 



GILIBERTIA (J. E. Gilibert, 1741-1814, France, 

 physician and botanist). Araliacex. A genus of very 

 few Trop. American shrubs (if Dendropanax is sepa- 

 rated) that are not known in cult. The name is one 

 frequently but incorrectly used by gardeners for 

 Trevesia, and G. palmata is described under that genus. 

 G. paniculata and one or two others are referred to 

 Polyscias. Gilibertia differs from Trevesia in haying parts 

 of the fl. in 6-8's instead of 8-12's, and in its simple 

 entire Ivs. From Dendropanax it differs mostly in its 

 6-8-merous rather than 5-merous fls. N. TAYLOR. 



GILLENIA (dedicated to an obscure German botanist 

 or physician of the seventeenth century, A. Gille or 

 Gillenius). Syn. Porter unthus. Rosacex. Excellent 

 graceful plants for the mixed border, rockeries, or 

 other hardy gardens. 



Erect, perennial herbs, 2-4 ft. high, with nearly 

 sessile, 3-foliate, or 3-parted, stipulate Ivs.: fls. white 

 or pinkish, loosely panicled, perfect, perigynous; cup- 

 shaped receptacle narrow, somewhat contracted at the 

 mouth, 5-toothed; petals strap-shaped, unequal, 4-8 

 lines long; stamens 10-20, very short; pistils 5, superior, 

 lightly coherent, later distinct, pubescent: fr. consist- 

 ing of 5 2-4-seeded follicles. Two species. They are 

 hardy and of easy cult, in any good soil. Prop, by 

 seeds or division.
