 with 2 forms of yellow fls. in axillary clu.sters, the normal 

 fls. having a gland-bearing calyx, a 3-angled stj'le and 

 3 ovaries, and conspicuous clawed petals; abnormal fls. 

 with an eglandular calyx, no style and 2 ovaries, and 

 often rudimentary petals. — Ten to 15 species. J. gracilis,

 slender, twining or trailing: Ivs. lanceolate-linear, both 

 surfaces silky: peduncles mostly dichotomously 2-fld.; 

 bracts linear, as long as the pedicels. Common through- 

 out Texas, south of the Colorado, and west to New Mex.

JAPARANDIBA (probably a vernacular name). 

 Lecythidacese. Gustavia, which is retained by the 

 "nomina conservanda" of the Vienna code. Upward 

 of 20 trees and shrubs of Trop. Amer., Uttle known in 

 cult. Lvs. large, ovate or spatulate, alternate, ser- 

 rate: fls. showy on 1-fld. somewhat umbelled peduncles; 

 calyx-tube turbinate, the border entire or 4-6-lobed; 

 petals 6-8, nearly equal; stamens many, in many series, 

 annulate or cupulate; ovary 4-6-celled: fr. a fibrous 

 few-seeded berry. — Some of the species may be found 

 in choice collections of warmhouse plants, but only 

 J. speciosa, Kuntze {Gustama specidsa, DC), from 

 Colombia, seems to be offered in this country (S. Calif.). 

 Tree: lvs. thick, oblong-lanceolate, acuminate, nar- 



rowed at base, entire, punctulate above, reticulate 

 beneath, about 3J4 in. long: fls. fascicled, fragrant, 

 6-petaled, white, 2-3 in. long; calyx nearly entire and 

 with the pedicel tomentose. Colombia. 



J. graciUima, Niedz. (Gustavia gracillima, Miers). Slender tree, 

 glabrous: fla. 4 in. diam., roae-red, solitary or in pairs, from the 

 If.-axils on young plants and on the wood in old plants: lvs. close 

 together, recurved, to 18 in. long, obianceolate or much narrower, 

 serrate. Colombia. B.M. 6151. G.Z. 21, p. 49. — J. plerocdrpa, 

 Niedz. (G. pterocarpa, Poit. ). Fls. with 6 large obtuse white petals; 

 calyx deeply 5-6-lobed ;_ ovary 5-winged: lvs. thick, long-petioled, 

 obovate-Ianceolate, entire or very nearly so, acuminate: style 

 elongated. Guiana. B.M. .5239. — J. superba, Kuntze (G. superba, 

 Berg. G. insignia, Lind.). Shrub or small tree: corolla 5-6 in. diam., 

 cream -white, outaide tinged rose: lvs. dark green and gloasy, 

 obovate-Ianceolate, acuminate, much attentuate at base, sessile or 

 nearly so, spinuloae-toothed. I3.M. 5069. T H R 



JASIONE (ancient name of no application to this 

 plant). Campanulacese. SmaU blue-flowered or rarely 

 white-flowered plants for the border or the rock-garden. 



Jasione is easily distinguished from its allies by the 

 fls. being borne in a head with an involucre, the calyx 

 reduced to 5 very slender lobes, the corolla cut into 5- 

 awl-shaped strips, and the anthers somewhat united at 

 their ba.ses; these characters make the infl. to resemble 

 the Composita;, but it is readily distinguished by the 

 many-seeded caps. — Species 5 or 6, in Cent, and W. Eu. 

 and the Medit. region. They differ widely in duration 

 and habit. Prop, by division and se^'d. This includes 

 the shepherd's scabious, a hardy herbaceous peren- 

 nial plant of compact habit, about a foot high, and 

 bearing globose heads 2 in. diam. composed of very 

 many light blue fls. It is of easy cult, in any garden 

 .soil, grows either in fuU sunlight or partial shade, and 

 is equally adapted for borders, edgings, or the rockery. 

 The common annual scabious (Scabiosa) belongs to the 

 tea.sel family, and has 4 stamens, while the shepherd's 

 scabious has 5 stamens. 



perennis, Lam. Shepherd's Scabious. Sheep 

 Scabious. Sheep's-bit. Perennial: st. erect, sparingly 

 if at all branched: root-lvs. obovate, in the non-florif- 

 crous plants forming a tufted rosette; st.-lvs. oblong- 

 linear, entire; peduncles long, leafless; bracts ovate, 

 serrate-dentate; fls. blue. S. Eu. July, Aug. B.R. 

 505. B.M. 2198. 



montana, Linn. Annual or biennial (if biennial, 

 bearing a winter tuft or rosette of radical lvs.): sts. 

 erect, 1 ft. high, sometimes short and more or less 

 decumbent: lvs. linear or lanceolate, undulate, some- 

 what hairy: fls. pale blue, on long terminal peduncles; 

 involucral bracts ovate. Great Britain to Caucasus. — 

 The seaside form, (var. littoralis) is said to be usually 

 biennial. This species is also called sheep's-bit. 



hiimilis, Lois. Dwarf, about 6-9 in. high, perennial: 

 sts. simple, ascending: lvs. flat and entire, linear- 

 obovate: fls. blue on short peduncles. Pyrenees; useful 

 in rock-gardens. July, Aug. l. H. B.f 



JASMINUM (Arabic name, from which have come 

 Jessamine, Jasmin and Jasminum). Oleacese. Jasmine. 

 Jessamine. Climbing or erect shrubs, with attractive 

 flowers, mostly very fragrant, prized for planting in 

 mild climates and frequently gro^m under glass. 



Leaves opposite or alternate, pinnate but sometimes 

 reduced to 1 1ft. (petiole jointed) : fls. on the ends of the 

 branchlets, or twin, or in dichotomous cjTnes; corolla 

 yellow or white, sometimes reddish, salver-shaped, the 

 4-9 or more lobes convolute in the bud, much exceeding 

 the calyx; stamens 2, included in the corolla-tube; 

 ovary 2-loculed, with \-i erect ovules: fr. a 2-lobed 

 berry, or sometimes the carpels separate, the carpels 

 mostly 2-seeded. — Probably upwards of 200 species, 

 widely distributed in warm parts of Eu., Asia, Afr., and 

 the Pacific region; nearly absent from Amer. The genus 

 is closely allied to Ligustrum, but differs in the com- 

 pound lvs. and twin-carpeled frs. Olea is also a related 

 genus.
