L. H. B. 



LEYCESTERIA (Wm. Leicester, judge in Bengal). 

 Including Pentapyxis. Caprifoliaceae. Himalayan and 

 Chinese small shrubs with whorled small flowers, suita- 

 ble for mild climates. 



Deciduous: Ivs. opposite, simple, the stipules very 

 small or none: fls. in erect or drooping verticillate leafy- 

 bracted spikes; calyx persistent, unequally 5-lobed; 

 corolla funnelform, nearly equally 5-lobed and swollen 

 at the base; stamens 5, on the corolla-tube; ovary 

 5-8-celled, the stigma capitate: fr. a berry, sometimes 

 eaten by birds. -Species about 4, only one of which 

 appears to be in the trade; prop, by seeds and by cut- 

 tings. The genus is allied to Lonicera, from which it 

 differs in its nearly regular corolla, and fr. with more 

 locules; and to Diervilla, which differs in 2-loculed caps. 



formSsa, Wall. (L. elegans, Hort.?). Strong-grow- 

 ing, with fistular (hollow) branches, 6 ft. : Ivs. broadly 

 ovate to ovate-lanceolate, acuminate, entire or toothed, 

 more or less puberulous beneath : fls. purplish, fascicled 

 in whorls in drooping leafy spikes or spike-like racemes: 

 fr. dark red, subglobose. Himalaya, 5,000-10,000 ft., 

 to W.China. B.M. 3699. G.W. 7, p. 355. B.R. 25:2. 

 M.D.G. 1908:330. Gt. 28, p. 181. R.H. 1857, p. 109. 

 Grown in England and apparently in Calif. Var. varie- 

 gata, Hort., has variegated foliage. Var. rdsea, Hort., 

 has rose-colored fls. 



LHOTZKYA (Dr. John Lhotzky, botanical traveler 

 in Australia, and elsewhere). Myrtacese. Heath-line 

 Australian evergreen shrubs of 10 species, rarely grown 

 under glass. Lvs. small, scattered or opposite, entire 

 and rigid: fls. sessile or nearly so, solitary or in leafy 

 heads, white, yellow, pink or purple; calyx with an 

 elongated ribbed tube and 5 broad very obtuse lobes; 

 petals 5, entire and spreading; stamens many, in several 

 rows. L. acutifolia, Lindl., has white or yellowish fls. 

 and linear mucronate Ivs. 

 %-}/% in. long. L. ericmdes, 

 Schauer, has white or whitish 

 fls. and slender short linear 

 3-angled Ivs.: erect, nearly 

 glabrous, the fls. being in 

 fascicles midway of the leafy 

 branchlets. B.M. 7753. L. 

 violacea, Lindl., has purplish 

 fls. and oblong very obtuse 

 short Ivs. 



LIATRIS (a name of un- 

 known derivation). Syn. 

 Lacindria. Compdsitse. BLAZ- 

 ING STAR. BUTTON SNAKE- 

 ROOT. Hardy perennials, 

 confined to eastern and south- 

 ern North America, best 

 adapted to the wild-flower 

 border. 



They are erect often resin- 

 ous herbs, simple or branched, 

 and arising from a tuber: 

 Ivs. alternate, narrow, 1-5- 

 nerved: fls. in racemose or 

 spicate heads; receptacle flat, 

 or slightly convex, naked; 

 corolla regular, its tube slen- 

 der and 5-lobed. Twenty- 

 five or more species. 



The most showy are L. 

 elegans and L. pycnostachya. 

 All produce flowers in wand- 

 like spikes or racemes, the 

 petaloid coloring of the in- 

 volucral bracts often adding 

 to the effect of the usually 

 bright rose-red or purple flow- 

 ers. Their flowers are pro- 

 duced in late summer and 

 autumn. They multiply by 

 offsets from their corm-like 

 base, or may be grown from 

 seed, which should be sown 

 in autumn. They will grow 

 and produce flowers in poorer 

 soil than most garden plants, 

 but thrive best in good, rich 

 garden soil, and require no 

 special care. When grouped in masses they give best 

 results. They are scarcely domesticated as yet.
