 . v. elegans (elegant). A 

 entire plant being suffused with cream-coloured spots, 



J. V. elegans (elegant). A handsome free-growing variety, the 

 entire plant being suffused with cream-coloured sots, which it 

 retains throughout the winter and summer. 



J. V. glanca (silvery). Silver Cedar. A very handsome variety, 

 having a whitish appearance when making growth. It has a 

 pretty cone-shaped habit, and is thickly branched from the ground 

 upwards. 



J. V. humilis (dwarf). A distinct and attractive variety, having 

 the shoots branching out in a remarkable angular form. 



J. V. pendula (pendulous). Weeping Red Cedar. According 

 to Gordon (" Pinetum "), " there are three forms of the pendulous 

 Bed Cedar to be found in collections ; one of the male form, 

 another the female, and the third a bright green one. The male 

 kind has shorter and much more numerous branchlets, while the 

 female one has longer, more slender, and much fewer branchlets ; 

 the third variety is of a light glossy green." The female form is 

 superior to the others. 



J. v. Schotti (Schott's). A distinct variety, of pyramidal habit, 

 and distinguished by its peculiar light green foliage. 



J. V. tripartite (three-parted). A very pretty dwarf spreading 

 variety, somewhat resembling J. Sabina in habit, but much 

 denser.

JURINEA (derivation not explained). ORD. Com- 

 posite. A genus containing about forty species of hardy 

 herbaceous perennials, natives of South Europe, Western 

 and Central Asia, and distinguished from allied genera in 

 the four-sided, somewhat top-shaped achenes being crowned 

 with a pappus of unequal rough hairs. None of the 

 species introduced are of much horticultural value, 

 although occasionally seen in gardens. They thrive in 

 any ordinary garden soil. Increased by seeds, or by 

 divisions of the roots, in spring. 



J. depressa (depressed), fl.-heads purple. June. I. stalked, 

 lyrate, pale green above, canescent beneath ; the terminal seg- 

 ment large, rounded ; the lateral ones small, ovate or triangular, 

 entire. A. 6in. Caucasus, 1837.

 lobes oblong, obtuse, angulate, white-tomentose underneath.

JUSSIJEA (named in honour of the celebrated family 

 of Jussieu). STN. Jussieua. ORD. Onagrariece. A 

 genus comprising about thirty species of stove or green- 

 house herbs, or rarely shrubs, very rarely small trees, 

 often marsh-loving, and a few aquatic ; they extend over 

 the tropical regions of the globe, but are mostly found 

 in America. Flowers white or yellow, axillary, solitary, 

 very short or long-stalked ; calyx with an elongated 

 tube, and four to six persistent lobes ; petals four 

 to six, spreading. Leaves alternate, very frequently 

 membranaceous and entire, rarely coriaceous and ser- 

 rated. All the species thrive in a loamy soil, the 

 aquatics requiring a basin of water. Propagation may 

 be effected either by seeds or by divisions. 



J. frutescens (shrubby), fl. yellow, shortly pedicellate ; calyx 

 lobes four, ovate, acute, pubescent outside ; tube cylindrical, 

 eight-furrowed. June. I. sessile, lanceolate-linear, glandulose,

 acuminate, three-nerved ; petals orbiculate, nearly equal ; tube 

 elongated, tetragonal. I. sub-sessile, elliptic, acuminate, nerve- 

 veinld. Madagascar. (B. M. 2530.) 



J. repens grandiflora (creeping, large-flowered). /. yellow, 

 2in. in diameter, drooping before expansion ; petals twice as long 

 as the five calyx segments. May to August. I. lanceolate, acute. 

 Stem creeping at base, 2ft. to 3ft. long. North America (in 

 marshes), 1812. Greenhouse herb. (B. M. 2122.) 



JUSSIEUA. A synonym of Jussiaea (which see). 



JUSTICIA (named after J. Justice, a Scotch horti- 

 culturist). STNS. Adhatoda (in part), Athlianthus, and 

 Tyloglossa. ORD. Acanthacece. A large and much-con- 

 fused genus, comprising about 100 species of herbs and 

 sub-shrubs, occurring in tropical and sub-tropical regions, 

 chiefly in India and Southern Africa. Flowers white, 

 violet, pink, or rarely red. Leaves entire. Justicias are 

 mostly of easy culture, and thrive in a compost of about 

 equal parts of loam and leaf soil. Propagated by cut-

tings, inserted preferably in single pots, in spring, and 



placed in a close, warm frame. Young plants should be 



pinched, to encourage a bushy growth. They may be 



cultivated in frames all the summer, but require a stove 



or warm greenhouse temperature in winter.

 minal, leafy. June and July. I. elongated. A. 3ft. India, 1800-

 ORD. Magnoliacece. A genus comprising about seven 

 species of half-hardy climbing shrubs, natives of the 

 mountains of Eastern tropical Asia. Flowers whitish or 

 reddish, axillary or solitary. Leaves coriaceous, rarely 

 membranaceous. Only one species is in general cultiva- 

 tion ; it thrives in almost any soil, if grown against a wall. 

 Cuttings of nearly ripened shoots will root in sand, under 

 a bell glass.

 one-flowered, usually solitary, longer than the petioles. June to 

 September. 1. oval or oblong-oval, acute at both ends, serrated, 

 smooth, thick. Japan, 1846. Half-hardy shrub. (S. Z. F. J. 17.)

!RIA (named after E. Ksempfer, 1651-1716, 

 a German naturalist). Including Cienkowskia and Mono- 

 lophus. ORD. Scitaminece. A genus comprising about 

 eighteen species of ornamental stove herbaceous peren- 

 nials, natives of tropical Africa and Asia. Flower-spikes 

 on leafy stems, or on radical, scaly, terminal scapes ; 

 corolla tube elongated, exserted ; lobes lanceolate, acute, 

 equal, spreading or reflexed. Leaves small, or rather 

 large, generally elliptic or ovate-lanceolate, acuminate. 

 Ksempferias thrive in well-drained fibry loam and peat. 

 During the growing season, they require an abundant 

 supply of water ; but when the leaves turn yellow, this 

 should be almost entirely withheld, and the pots stowed 

 away under staging, where no drip can reach them. 

 When growth recommences, the plants should be shaken 

 out and repotted.

 spicuous band of white. Moulmein, 1882. A very attractive and 

 desirable variegated plant. See Fig. 355, for which we are in- 

 debted to Mr. Wm. Bull. (G. C. n. s., xvii. 713.)
