JABOROSA (derived from the Arabic word Jabarose, 

 which was applied to the Mandrake, from its affinity to 

 that plant). OED. Solanacece. A genus comprising six or 

 seven species of pretty greenhouse or hardy herbaceous 

 perennials, one of which is from Mexico and the rest from 

 the Andes and extra-tropical South America. Flowers 

 white or yellowish, solitary ; corolla campanulate or tubular. 

 Leaves dentate, runcinate-pinnatifid, or dissected. The 

 species thrive in a light sandy-loam soil. Increased by 

 divisions of the plant; or by seeds, sown during spring. 

 Cuttings of young shoots will root under a handlight. 

 The only species yet introduced to cultivation is the 

 one here described. 



J. integrifolia (entire-leaved), fl. white ; corolla 2in. long, with 

 acute segments ; scapes length of petioles. I. petiolate, oval, 

 nearly entire, h. 6in. Buenos Ayres. A pretty little hardy 

 plant, forming a mass of deep green foliage ; it thrives in a 

 southern aspect. (B. M. 3489.) 



JACARANDA (the name of one of the species in 

 Brazil). STNS. Icaranda, Kordelestris. ORD. Bigno- 

 niacecB. A genus comprising about thirty species of 

 ornamental stove shrubs and trees, somewhat resembling 

 in habit the fine-leaved species of Acacia. Flowers blue 

 or violet, showy, panicle d, usually terminal; corolla tubular 

 at the base, much dilated above, campanulate, ventricose 

 beneath. Leaves opposite, bipinnate. J. mimosifolia is, 

 probably, the best-known of the two or three species 

 in cultivation. It thrives in a compost of sandy peat 

 and fibry loam; plenty of drainage is most essential. 

 Cuttings of half-ripened shoots will root, during the early 

 summer months, in sand over sandy peat; they should 

 be placed in heat, and kept shaded until well rooted. 

 The same treatment will answer with the second species. 

 J. mimosifolia (Mimosa-leaved), fl. blue, drooping; panicles 

 large, terminal, naked, erectly pyramidal ; corolla silky. Early 

 summer. I. about lift, long, bipinnate, with many pairs of 

 opposite pinnae, each pinna bearing ten to twenty-eight pairs of 

 trapezoid-oval-oblong, mucronate, downy leaflets. h. 10ft. 



Brazil, 1818. Shrub. (B. B. 631 ; B. M. 2327, under name of 

 J. ovaltfolia.) 



J. tomentosa (downy), fl., corolla dark purple, downy exter- 

 nally, with a short tube ; limb tubular-campanulate, IJin. long, 

 with a pale spot under the upper lip. June. I. bipinnate, downy ; 

 leaflets with an odd one, ovate-rhomboid, acute, very unequal. 

 h. 20ft. Mexico, 1824. Shrub. (B. B. 1103.) 



JACINTH. A name for the Hyacinth. 

 JACK-IN-A-BOX. See Hernandia. 

 JACKSONIA (named after George Jackson, a Scotch 

 botanist). ORD. Leguminosce. A genus comprising about 

 twenty-eight species of rigid, greenhouse, leafless, shrubs 

 or sub-shrubs, all natives of Australia. Flowers yellow, 

 mixed with purple, small, in lateral or terminal racemes 

 or spikes, or scattered along the branches; bracts small, 

 scale-like. Leaves replaced by very minute scales at 

 the nodes. Branches rigid, terete, angular or winged. 

 The species thrive in a peat and loam soil. Cuttings of 

 half -ripened shoots will root in sand, under a hand glass, 

 during April. Jacksonias are very rarely seen in culti- 

 vation. 



J. scoparia (broom-like), fl. yellow, disposed in one-sided 

 racemes, either terminal or from the upper nodes. Summer. 

 Branches angular, h. 2ft. to 6ft. 1803. Plant arborescent, un- 

 armed. This tree is known in New South Wales as Dogwood, on 

 account of the offensive smell emitted by its wood when burning. 

 (L. B. C. 427.) 



JACK-TREE. A common name of Artocarpus 

 integrifolia (which see). 



JACOBINIA (derivation doubtful). Including Cyrt- 

 anthera, Pachystachys, Sericographis. ORD. Acanthacece. 

 A genus comprising about thirty species of stove erect 

 herbs or shrubs, natives of tropical America, from Brazil
