Lagenophora continued. 



narrowed into a petiole, usually all under 2in. t rarely above 3in., 

 long. Australia. 



L. Porsteri (Forster's). fl.-heads yellow and purple, small; scape 

 slender, 2in. to 6in. long. I. iin. to lin. long, obovate or orbicular- 

 oblon?, obtuse, crenate toothed or lobed towards the base. New 

 Zealand, 1837. A small, slender, Daisy -like plant. 



LAGERSTROMIA (named after Magnus Lager- 

 strom, of Gottenberg, 1696-1759, a friend of Linnaeus). 

 OBD. Lythrariece. A genus containing about fourteen 

 species of very handsome stove or greenhouse trees 

 or shrubs, natives of tropical and sub-tropical Eastern 

 Asia. Flowers on axillary peduncles, generally consti- 

 tuting panicles or racemes at the tops of the branches. 

 Leaves opposite, entire. Only one or two species are 

 in cultivation ; these succeed in a compost of equal parts 

 peat and loam. Throughout the winter months, the 

 only attention needed consists in giving just sufficient 

 water to prevent the soil getting dust- dry. As the 

 spring advances, both the quantity of water and the 

 amount of heat should be increased. Propagated, in 

 spring, by cuttings of small, firm, side shoots, placed in 

 bottom heat. 



L. Flos-reginse (Queen's flower). /. of a beautiful rose-calour in 

 the morning, growing deeper through the day, until they become 

 purple in the evening, large, from 2in. to 3in. in diameter ; petals 

 orbicular, undulated, on short claws ; panicle terminal. I. oblong, 

 glabrous, dark green. A. 50ft. to 60ft Malay to China, 1792. 

 Stove. SYN. L. ReginiK. (B. F. S. 29.) 



L. Indlca (Indian).* fl. bright pink, large, very handsome ; petals 

 curled, on long claws ; panicle many-flowered, terminal. Summer. 

 I. roundish-ovate, acute, glabrous. Branchlets acutely tetragonal, 

 nearly four-winged, h. 6ft. to 10ft. China, 1816. Stove or green- 

 house. (B. M.405.) 



L. L alba (white), fl. pure white, in which particular alone this 

 variety differs from the type, and to which it forms a very pleasing 

 contrast. China. 



L. Reginae (Queen's). A synonym of L. FUt-reginae. 



IiAG-ETTA (native name of the genus). Lace Bark. 

 ORD. Tliymeloeacece. A genus of two species of elegantly- 

 reticulated trees, native of the East Indies. Flowers 

 few, in loose terminal spikes or racemes, sessile, or 

 shortly pedicellate. Leaves alternate, oblong or broad. 

 L. lintearia, the species in cultivation, is a stove ever- 

 green tree, the inner bark of which furnishes the beau- 

 tiful Lace Bark of commerce. It thrives in a compost 

 of peat and fibry loam. Propagated, in spring, by cut- 

 tings of half-ripened shoots placed in sand, under a 

 glass, in bottom heat. 



I*. lintearia (linen), fl. white, with a tubular coloured perianth, 

 a distended tube, and contracted throat. 1. ovate, acute, h. 6ft. 

 Jamaica, 1793. (B. M. 4502.) 



LAGUNJEA. Now included under Hibiscus 

 (which see). 



LAGUNARIA (a name given on account of its simi- 

 larity to Laguncea, a genus now included under Hibiscus, 

 and which is so called in honour of Andres de Laguna, 

 a Spanish botanist, 1499-1560). OED. Malvaceae. A 

 small genus (two species) of greenhouse evergreen trees, 

 one of which is from Norfolk Island, and the other from 

 Eastern Australia. Flowers large, rising singly from the 

 axils of the leaves. Leaves entire, lanceolate. The under- 

 mentioned is probably the only species in cultivation. It 

 thrives best in a compost of peat and loam. Propagated 

 by cuttings of half-ripened shoots, placed under glass, in 

 a gentle heat, during May. 

 L. cuneiformls (wedge-shape-leaved). A synonym of Fugosia 



cuiteir'urmis. 



L. Patersonii (Paterson's). fl. pale red, or nearly white, large, 

 solitary, axillary. Summer. I. lanceolate-oblong, quite entire, 

 covered with whitish scales beneath, h. 20ft. Norfolk Island, 

 1792. (B. M. 769, under name of Laguncea Patersonia.) 



LAGURUS (from lagos, a hare, and oura, a tail). 

 Hare's-tail Grass. ORD. GraminecB. A monotypic genus, 

 distinguished by the inflorescence being in round spike- 

 like panicles, and the scarious glumes ending in a long 

 fringed bristle The species is one of the handsomest 



Lagnras continued. 



of British grasses. It is a hardy annual, and thrives 

 best when sown in pots during August and September, 

 wintered in a cold frame or greenhouse, and planted out 

 in the open the following spring. 



FIG. 372. LAGURUS OVATUS. 



L. ovatus (ovate).* /., spike ovate, many -flowered, woolly. June 

 to September. I. lanceolate, acute, ribbed, downy on both sides ; 

 sheaths inflated, ribbed, very downy. Culms about 1ft. high, 

 erect, round. Mediterranean region, West Coast of Europe, 

 Channel Islands. See Fig. 372. (Sy. En. B. 1712.) 



Ii AIi AGE. Now included under Bossicea. 

 LALLEMANTIA (named after J. E. Lallemant, of 

 the Botanic Garden at St. Petersburg). ORD. Labiatce. 

 This genus contains about four species of annual or 

 biennial, glabrous or canescent herbs, natives of Asia 

 Minor, &c. Flowers blue, small; whorls axillary, com- 

 monly six-flowered; calyx erect. Leaves, lower ones 

 on long petioles, toothed; superior and floral ones nar- 

 rower, and more sessile and entire. The only species 

 yet introduced is the one here described. For culture, 

 see Dracoceplialum. 

 Ii. canescens (hoary), fl. blue, whorled ; bracts oblong, ciliated ; 



calyx striated, pubescent ; tube of corolla longer than calyx. 



July and August. I., lower ones narrow, on long petioles ; upper 



and floral ones sessile, shortly narrow at the base, all obtuse.

LAMARCKIA (named after J. B. Lamarck, 1744- 

 1829, the great French naturalist). SYN. Chrysurus. 

 OBD. Graminece. A monotypic genus. The species is 

 a pretty, many-stemmed, low, annual grass, generally 

 included by seedsmen in collections of ornamental 

 grasses. It thrives when sown in spring, in the open 

 border, but attains a larger size if treated as recom- 

 mended for Laguros (which see). 

 L. aurea (golden).* /., inflorescence in simple crowded panicles ; 



spikelets stalked, two-flowered, one fertile and the other sterile, 



South Europe and North Africa. 



LAMBERTIA (named after A. B. Lambert, 1779- 

 1825, a distinguished patron of botany). ORD. Proteacece. 

 A genus containing eight species of greenhouse ever- 

 green shrubs, endemic in extra-tropical Australia. Flowers 

 red or yellow, usuaUy long, solitary or seven together, 

 sessile within an involucre of imbricate coloured bracts. 

 Leaves mostly in whorls of three, rarely of four, or 

 sometimes scattered at the base of luxuriant shoots, 

 entire, or with spinescent teeth. Lambertias thrive in 

 a compost of sandy peat and fibry loam. Ample drainage 

 must be given. Propagated by cuttings of young and 

 rather firm shoots; or by seeds, sown in slight heat. 

 L. formosa (beautiful).* fl., involucres terminal, usually solitary, 



seven-flowered ; inner bracts narrow, silky-pubescent outside ;
