gated, during summer, by nearly-ripened side shoots, 
placed in a sandy soil, under a bell glass. Probably 
the two species described below represent all introduced. 
L. floribunda (bundle-flowered). jl. white; racemes axillary, 
compound, shorter than the leaves. April and May. l. lanceolate, 
attenuated at both ends, smooth; stipules lateral, setaceous. 
h. 2ft. to 3ft. Australia, 1797. (L. B. C. 1118; A. B. R. 520, 
under name of Huosma albiflora.) 
L. latifolia (broad-leaved), f. white, disposed in terminal 
panicles, composed of opposite, dichotomous, and trichotomous 
peduncles. Summer. l. obovate, acutish at both ends. h. 3ft. 
to 4ft. Australia, 1816, 
LOGANIACEZ:. A natural order of herbs, shrubs, or 
trees, of variable habit, closely allied to Rubiacew. They 
inhabit chiefly warm and tropical countries. Flowers 
often red, white, purplish, or pale citron, rarely yellow, 
axillary and solitary, or racemose or corymbose, some- 
times in a terminal corymb or panicle. Leaves opposite, 
stipulate, or exstipulate when the dilated and connate 
bases of the petioles embrace the stem, with a short, 
sometimes obsolete border. Stem woody, rarely herba- 
ceous. Most Loganiacem have a very bitter juice. The 
species of Strychnos contain in the bark of their root, 
and in their seeds, two alkaloids, combined with a peculiar 
acid, the principles which are extremely their 
action on the nervous system is very powerful. There 
are about thirty genera and 350 species. ples

LOGWOOD. ‘see Hematoxylon. 
LOISELEUREA (named after Loiseleur Dveslong- 
champs, 1774-1849, a French botanist, who published a 
Flora of France, and other botanical works). Syns. Chame- 
cistus, Chameledon. Orv. Ericacew. A monotypic genus, 
the species being a low-trailing evergreen shrub, well 
adapted for cultivating in rock-gardens, in a moist 
sandy-peat soil. Propagated by layers. 
L. procumbens (trailing). f. rose, small, in short, terminal 
clusters ; corolla bell-shaped. July. J. about din. long, opposite, 
revolute, smooth. Branches spreading and procumbent. Arctic 
and alpine regions of Northern hemisphere (Britain—only in the 
Scotch Highlands). SYN. Azalea procumbens. (Sy. En. B. 884.) 
LOLIUM (the old Latin name, used by Virgil and 
Pliny). ORD. Graminee. A widely-dispersed genus of 
grasses. Upwards of twenty species have been described ; 
these may probably (according to Bentham and Hooker) 
be reduced to two or three. They are of no value for 
horticultural purposes. The “tares” of Scripture are 
supposed to refer to the Darnel, L. temulentum. L. itali- 
cum, the Italian Rye Grass of agriculturists, is one of 
the numerous cultivated annual or biennial forms (not 
known in a wild state) of the common British L. perenne. 
LOMAGRAMME PTEROIDES. According to 
Mr. Baker, this is an abnormal form of Acrostichum 
Blumeanum, with the sori in a line along the edge of 
pinnæ, rather narrower than the usual barren ones. 
LOMARIA (from loma, an edge; referring to the 
position of the spores on the fronds). ORD. Filices. 
Including Lomaridium, Lomariopsis. A rather large 
genus (about fifty species) of handsome stove, green- 
house, or hardy ferns, of world-wide distribution, but 
having its head-quarters in the South temperate zone. 
Froncs Aimorphous, usually once pinnatifid or pinnate, 
rarely simple or bipinnate. Sori linear, continuous, parallel 
with the midrib, and occupying the whole or nearly the 
whole of the space between it and the edge; involucre 
membranous, formed of the revolute edge of the frond. 
The species of this genus are, for the most part, unex- 
celled for the decoration of conservatories, dinner tables, 
Ke. The large-growing species thrive best in a compost 
of loam and peat, to which may be added a small quan- 
tity of silver sand. The smaller sorts will require scarcely 
any loam. For general culture, see Ferns.
