LEUCOPHYLLUM 



the valley of the lower Rio Grande more generally dis- 

 tributed, and certainly there is not one of them which 

 more delights the traveler in the early spring months, 

 when the large, violet-purple flowers of this plant 

 heighten the effect of its brilliant silvery foliage." 

 (G."P.3:488.) 



Leucophyllura has only 2 species. Lvs. all alternate, 

 ovate or obovate : calyx .5-eut ; corolla tube broad and 

 short ; lobes 5, rounded ; stamens 4, didjTiamous, in- 

 cluded, fixed at the base of the corolla: ovary 2-celled; 

 ovules numerous: capsule 2-valved: seeds oblong. 



Tex&num, Benth. Loose-growing, straggling shrub, 

 4 or f) ft. high in the wild, 8-10 ft. high in cuU. Lvs. 

 K-1 in. long, obovate : fls. axillary, slightly hairy within.

LEUCOSTfiGIA (Greek, white roof; alluding to the 

 iijilusia). I'lili/jiodiiiceis. A small genus of Indian ferns 

 allied to Davallia, with a small, narrow, thin indusium 

 attached by its base, with the apex and sides free. The 

 leaves are mostly tri-quadripinnate. For cult., see 

 Baca Ilia. 



pirvula, Wallich. Rootstocks wide-creeping, scaly: 

 lvs. nearly sessile, deltoid, less than 1 in. long, half as 

 wide, usually tripinnate. Singapore and Borneo.

LEUCOTHOE (Greek mythological name; daughter of 

 Nereus). A'ricitceif. Including Arjarista. Ornamental 

 low evergreen shrubs, with alternate, short-petioled, 

 usually serrate lvs. and with white, rarely pink or scar- 

 let, usually nodding Bs., in terminal or axillary racemes, 

 appearing mostly in spring. The S. American species, 

 which are very rare in cultivation, though they surpass 

 the other in beauty of the fls., are hardy only South, 

 while the other species can be grown as far north as 

 Mass. and western N. Y., the evergreen ones in sheltered 

 positions or with slight protection during the winter. 

 They are very h.andsome for borders of shrubberies or 

 as uiidergrnwtli in open woods. They thrive best in 

 sonicwiiat iin.ist. peaty or Sandy soil, and prefer shaded 

 or partly shadi'd silualicms, but also grow in full sun if 

 the soil is not loo dry. Prop. u.sually by seeds sown in 

 peaty, sandy soil in pans or boxes in spring, and treated 

 like those of Azalea or Rhododendron ; also by layers or 

 division ; the evergreen species grow from cuttings 

 under glass in late summer, but root rather slowly. 

 About 35 species in N. and S. America, Madag., Himal. 

 and Japan, formerly often united with Andromeda. Lvs. 

 evergreen or deciduous : fls. in axillary or terminal 

 racemes ; calyx 5-parted, imbricate ; corolla ovate or 

 cylindrical; stamens 10; anthers obtuse or 2-pointed at 

 the apex: capsule separating into 5 valves; seeds minute, 

 irregular. Most of the allied genera dift'er by the valvate 

 calyx, and Chamiedaphne by the valves of the capsule 

 separating into 2 layers, the inner one 10-valved. 



A. Li's. evergreen : racemes axillary, sometimeK clus- 

 tered, shorter than the lvs. 

 B. Racemes dense, sessile, many-fid.: pith of 

 branches solid.

 to 5 ft., with spreading and usually recurving branches, 

 pubei'ulous wln-n young : lvs., with short pubescent 

 perioirs, oval tu oliiong-lanceolate, shortly acuminate, 

 serrulate toward the apex, glossy above, pale and sparsely 

 pubescent beneath when young, 2-A in. long: racemes 

 1-2 in. long: sepals brt)adly ovate; corolla white, usually

 narrower; corolla over Min. long, white, usually reddish 

 in bud. April, May. Va. to Ga. B.M. 1955. L.B.C. 

 14:1.320. — This species is handsomer than the former, 

 and also somewhat hardier: lvs. and fl.- buds assume 

 a beautiful purple hue, late in fall which is retained 

 through the winter.

 acuminate : racemes spreading and recurved : capsule 

 depressed and strongly lobed. April-June. Va. to Ala.

 it is not superior to the former ; the foliage of both

Leucothoe Catesbmi is one of our most ornamental 

 and popular hardy broad-leaved shrubby evergreens. It 

 is used for massing in connection with Kliodotlendrcns, 

 Kalmias, etc., serving as a base for these taller \aric- 

 ties. The shiny dark green leaves are borne with regu- 

 larity on a recurved stem often 2-3 ft. long, and some- 

 times coloring brilliant bronze and claret shades in 

 autumn when exposed to the direct rays of the sun. 

 Leuci>lli(ie sprays are largely used by florists in making 

 up di'si^'os and in connection with Galax leaves, usually, 

 hu\ve\-er, iTi the more informal pieces. They were intro- 

 duced to the trade about 1890. The fragrant flowers are 

 in the leaf axils, borne along the stem in early spring, 

 and are usually conspicuous, considering the fact that 

 the leaves are persistent. It is this graceful evergreen 

 spray effect, with tlje good color and dense habit, that 

 m:ikes Letieoiliui: so desirable as a plant for massing, 

 anil ;ilso the fact, jierhaps, that it is fairly easy to trans- 

 plant. Seeds are produced freely, and can be sown in 

 sphagnum moss and sand under glass, as Rhododen- 

 drons and Azaleas are grown, pricked off in flats and 

 planted outdoors in early spring, when the plants are a 

 few incdies high. Leucothoe is also propagated by di- 

 visiiiri. nndiTgniund runners and cuttings, the latter 

 being i)lunged in s;ind on the bench and given moderate 

 bottom heat. It is usually collected, however, in its na- 

 tive habitat, in small plants, transplanted to nursery rows 

 and grown for several seasons. Harlan P. Kelsey. 



LEVEEWOOD. Ostrya rirginica. 



LEVtSTICUM (a modification of a name given by 

 Dioscorides tosome umbelliferous plant). Umbetliferce. 

 Lovage is a plant grown for its aromatic seeds, which 

 are used in confectionary. The leaf-stalks were for- 

 merly blanched and eaten like celery. It is a tall, hardy 

 perennial herb, with large, 2-3 times divided radical lvs. 

 The plant may be propagated by seed sown as soon as 

 ripe, but when plants are already established root-di- 

 vision is less troublesome and risky. Division may bo 

 made in the autumn, but better in the spring. The di- 

 vided plants and the seedlings, when 2 or 3 in. tall, 

 should be set in checks 3 ft. apart in deep, rich soil. 

 When well established the plants remain profitable for 

 many years, demanding but little attention. The genus
