Logania continued. 



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), fl.. white; racemes axillary, 



compound, shorter than the leaves. April and May. I. lanceolate, 



attenuated at both ends, smooth ; stipules lateral, setaceous. 



h. 2ft. to 3ft. Australia, 1797. (L. B. C. 1118 ; A. B. B. 520, 



under name of Euosma albiflora.') 

 L. latifolla (broad-leaved), fl. 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. 



LOGANIACE2E. A natural order of herbs, shrubs, or 

 trees, of variable habit, closely allied to Ruliacece. 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 Loganiaceae 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 energetic ; their 

 action on the nervous system is very powerful. There 

 are about thirty genera and 350 species. Examples: 

 Gcertnera, Logania, Spigelia, Strychnos. 



LOGWOOD. See Haematoxylon. 



LOISELEUREA (named after Loiselenr Deslong- 

 champs, 1774-1849, a French botanist, who published a 

 Flora of France, and other botanical works). STNS. ChamcB- 

 cistus, Chanuidedon. OBD. Ericaceae. 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). fl. rose, small, in short, terminal 



clusters ; corolla bell-shaped. July. I. about iin. long, opposite, 



revolute, smooth. Branches spreading and procumbent. Arctic 



in the

nd alpine regions of Northern hemisphere (Britain only in t 

 cotch Highlands). SYN. Azalea procumbens. (Sy. En. B. 884.

LOLIUM (the old Latin name, used by Virgil and 

 Pliny). OBD. Graminece. 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 Eye 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 FTEROIDES. According to 

 Mr. Baker, this is an abnormal form of Acrostichum 

 Blumeanum, with the sori in a line along the edge of 

 pinna?, rather narrower than the usual barren ones. 



IiOMARIA (from loma, an edge ; referring to the 

 position of the spores on the fronds). OBD. 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. 

 Fronds dimorphous, 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, 

 &c. 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. 

 L. alpina (alpine).* rhiz. slender, wide-creeping, clothed with 



lanceolate ferruginous scales at the crown, barren fronds 4in. to 



Sin. long, iin. to jin. broad, linear-lanceolate, with spreading, 



Lomaria continued. 



close-placed, linear-oblone, obtuse pinnae, Jin. long, in. broad. 

 fertile .fronds on stipes 4in. to 12in. long ; pinnae narrower and 

 more distant. Involucre slightly intramarginal. Brazil. A 

 smaller plant than L. Spicant, with a slender, wide-creeping 

 rhizome, and the pinnae, especially of the fertile frond, broader 

 and shorter. Half-hardy. See Fig. 465.
