Lyonia continued. 



L. lignstrina (Privet-like). JL white, small, in pedunculate 

 clusters ; corolla nearly globose ; floriferous branches terminal, 

 panicled, nearly naked. June. I. obovate-lanceolate, sub-acu- 

 minated at both ends, almost entire, h. Sft. to 10ft. North 

 America, 1748. Hardy shrub. SYNS. L. paniculata (W. D. B. 37)

LYONSIA (named after Israel Lyons, 1739-1775, 

 Professor of Botany at Oxford, and author of a Flora 

 of Cambridge). OBD. Apocynacea. A genus comprising 

 about thirteen species of twining shrubs or sub-shrubs, 

 of which one is a native of New Caledonia, one inhabits 

 the Fiji Islands, and the rest are Australian. L. straminea, 

 the only species yet introduced, is a greenhouse evergreen 

 twiner, allied to Parsonsia. It thrives in a compost of 

 sandy peat, to which may be added a small quantity of 

 fibry loam. Increased, during April, by cuttings of the 

 young shoots, placed in sand, under a hand glass. 

 L. straminea (straw-coloured). /. striped, small ; corolla funnel- 

 shaped, with a five-parted, recurved, bearded limb ; cymes ter- 

 minal, trichotoinous. June. I. shortly-stalked, ovate-lanceolate 

 or lanceolate, glabrous. New South Wales, &c., 1820. 



LYPERIA (from lyperos, sad or sorrowful; alluding 

 to the dull, heavy colour of the flowers). OKD. Scrophu- 

 larine<B. A genus comprising about thirty species of 

 greenhouse herbs or sub-shrubs, of little ornamental value. 

 All are natives of South Africa. Flowers axillary, or in 

 terminal spikes or racemes, usually more or less viscous. 

 Lower leaves opposite; upper ones alternate, toothed or 

 much cut, often tufted in the axils, sometimes minute, 

 blackening in drying. This genus is allied to Zaluzi- 

 anskia (which see for culture). 



L. pedunculate (long-peduncled). A. white ; calyx three to four 

 times shorter than the corolla tube; limb of corolla a trifle 

 shorter than the tube ; pedicels over lin. long, axillary, filiform. 

 June to November. 1. petiolate, sub-fasciculate, obovate-cuneate, 

 deeply toothed, h. lift. 1790. Plant suffruticose, divaricately 

 branched, finely pubescent. (A. B. B. 84, under name of Buck- 

 nera pedunculala.) 



LYRATE. Shaped like a lyre. A leaf is Lyrate 

 when its apex is rounded and there are several small 

 lateral lobes towards its base. 



LYSANTHE. Included under Grevillea (which 

 see). 



LYSIMACHIA (Lusimachion, the old Greek name, 

 from lysis, dissolving, concluding, and mache, strife ; 

 in reference to the supposed soothing qualities of the 

 plant). Loosestrife. Including Lubinia. OBD. Primu- 

 laceas. A genus comprising about sixty species of 

 greenhouse or hardy, erect or creeping, glabrous or 

 pubescent, slender or robust herbs, often gland-dotted, 

 mostly natives of the temperate and sub-tropical regions 

 of the Northern hemisphere, while a few are found in 

 tropical and Southern Africa, Australia, the Pacific 

 Islands, and South America. Flowers white, yellow, 

 or rosy, rarely purple or blue, very rarely four-parted, 

 axillary or terminal, solitary, racemose, or in simple 

 corymbose umbels or paniculate racemes ; corolla hypo- 

 gynons, funnel-shaped or rotate, five-parted ; tube short 

 or very short ; lobes five or six, erecto-patent or 

 spreading, entire or toothed ; calyx five or six-parted. 

 Leaves opposite, alternate or whorled, sessile or petio- 

 late, entire. The species are all of easy culture, most 

 of them thriving best in a moist situation, such as 

 the margins of streams and ponds. Propagated very 

 freely by divisions, in late autumn or early spring. 

 Except where otherwise stated, the species described 

 below are hardy, and all of them are perennials.
