LUCUMA (the Peruvian name of one of the species). 
Syns. Guapeba, Sersalisia, Vitellaria. ORD. Sapotacee. 
A genus comprising about sixty species of lactescent 
stove trees and shrubs, mostly natives of South America, 
extending from Chili and Peru to Mexico and the West 
Indies, a few Australian or New Caledonian. Flowers 
produced in clusters upon the sides of the branches. 
Fruit large, fleshy, edible, somewhat egg-shaped, 3in. to 
Hin. long, covered with a rusty skin. Leaves scattered, 
leathery, entire. Probably L. mammosa is the only 
species in cultivation. For culture, see Chrysophyllum. 
L. mammosa (nippled). Marmalade Plum. fl. small, whitish, 
solitary. fr. large, oval or top-shaped, covered with a brownish 
rough skin, under which is a soft pulp, of a russet-colour, and 
very luscious. J. obovate-lanceolate and oblong, lft. to 2ft. long, 
cuspidate, glabrous. h. 50ft. to 100ft. South America, 1739. 
LUDDEMANNIA LEHMANNI. 
ches Lehmanni. 
LUDIA (from ludus, a game, sport; in allusion to the 
sportive and variable shapes of the leaves). ORD. Bixinee. 
A monotypic genus, the species being an evergreen stove 
shrub, native of the Mauritius, &c. It thrives in a compost 
of loam, peat, and sand. Propagated by cuttings, made of 
half-ripened shoots, and inserted in sand, under a bell glass, 
in bottom heat. 
L. sessiliflora (sessile-flowered). fl., axillary, sessile, or shortly 
pedicellate, calyx whitish ; anthers yellow ; sepals deflexed. July 
and August. J. variable, oblong or lanceolate, rigidly coriaceous, 
shining, acutish. A. 8ft. to 12ft. 1820. L. heterophylla is a form 
bom abnormal leaves, some entire and obovate, others spinose- 
entate. 
LUDISIA. A synonym of Hemaria (which see). 
LUDOVIA. A synonym of Carludovica (which see). 
LUFFA (Louf is the Arabic name of L. wegyptiaca). 
ORD. Cucurbitacem. A genus comprising about half-a- 
score species of glabrous, scabrous, or pubescent, stove, 
annual herbs, natives of the warm regions of the globe, one 
being indigenous to America. Flowers white, rather 
large, moncecious; racemes of the male flowers long- 
peduncled; female flowers solitary. Fruit oblong or 
cylindrical, smooth or prickly, fibrous within and con- 
taining many seeds. Leaves five to seven-lobed; petioles 
eglandulose at apex; tendrils twice or many-fid. Some 
of the gourds of this genus possess a very disagree- 
able odour. For culture, &c., see Gourds.

LUHEA (named after C. Van de Luhe, a German 
botanist, who wrote on the plants of the Cape of Good 
Hope at the end of the eighteenth century). Syn. 
Alegria. ORD. Tiliacee. A small genus (about sixteen 
species) of handsome stove trees, allied to Sparmannia, 
confined to the tropical parts of the New World. Flowers 
white or pink, showy, in axillary cymes or in terminal 
panicles. Leaves often dentate, stellate-tomentose under- 
neath, on short footstalks. The species thrive in a com- 
post of fibry peat and sandy loam. Propagated by cut- 
tings of half-ripened shoots, inserted in sand, under a 
bell glass, in bottom heat. Probably the species here 
described is the only one yet introduced.

LUISIA (said to be called after a Spanish botanist, 
Don Luis de Torres). Syns. Birchea and Mesoclastes. 
ORD. Orchidew. A genus comprising about ten species of 
stove epiphytal orchids, natives of the East Indies and 
Eastern Asia, extending from the Malayan Archipelago 
to Japan. The species have lateral spikes of dingy 
green, purplish, or yellowish, sub-sessile flowers. Leaves 
terete, rigid, rush-like. Stems erect. Two or three species

are in cultivation; they thrive on a block of wood, with 
sphagnum, and require a moist atmosphere in the summer, 
when in a growing state. Propagated by divisions.

laceous lip, Assam, 1869.

with an enormous development of downy roots. (B. M. 
under name of Cymbidium triste.)

yellowish-green ; lip reticulated with violet-purple. (. nilike,

shape of the seed-vessels). Honesty. Ok PD. Crucifere. 
A genus comprising two species cf very ornamental, 
hardy, annual, biennial, or perennial herbs, natives of 
Europe and Western Asia. Flowers lilac, large, ebrac- 
teate ; racemes terminal. Siliquas stipitate, broadly 
elliptic or oblong, compressed. Leaves petiolate, entire, 
cordate. Both species are well worth a place in any 
garden, and thrive best in a somewhat sandy soil. In- 
creased by seeds, or by divisions,
