LUTEOFUSCUS. 

 fuscous. 



Between yellow and 



LUTEOLTTS. Pale yellow. The same as 

 Flavescens. 



LUTESCENS. Yellowish. 



LUTEUS. Such yellow as gamboge. 



LUVUNGA. A genus of Indian auran- 

 tiaceous shrubs of climbing habit, often 

 spiny, having ternate leaves, and flowers 

 in axillary clusters or tufts. The calyx is 

 cup-like; the petals four or Ave, oblong; 

 the stamens eight to ten, free or combined 

 into a tube, with linear anthers ; the ovary 

 two to four-celled, with two ovules in each 

 cell. L. scandens has clusters of flowers 

 whose appearance and fragrance resemble 

 those of the orange. [M. T. M.] 



LUXEMBURGIA. A genus of Ochnacece, 

 consisting of showy branching smooth 

 shining trees or shrubs, with alternate lea- 

 thery serrulate stipulate leaves, and ter- 

 minal racemes of yellow flowers, having 

 five unequal deciduous sepals ; five imbri- 

 cate-convolute petals ; and hypogynous 

 stamens, eight or indefinite, with linear an- 

 thers biporose at the apex. The capsule is 

 leathery, one-celled, with numerous seeds. 

 They are natives of Brazil. [J. H. B.] 



LUXURIA, LUXURIES. Rankness ; an 

 unnaturally exuberant growth. 



LUZERNE. (Fr.) Medicago sativa. — 

 DE SUEDE, FAUCILLE, JAUNE, or SAU- 

 VAGE. Medicago falcata. 



LUZULA. A genus of perennial herba- 

 ceous plants allied to the rushes, from 

 which they may be distinguished by their 

 seed-vessels each containing three seeds 

 only, and by their flat leaves which are ge- 

 nerally furnished with sparse long hairs. 

 Several species are British. One of them, 

 L. campestris, is popularly called a grass, 

 but may at once be detected by its pilose 

 leaves. L. sylvatica is a large species, bear- 

 ing on leafy stalks, two feet high, its 

 spreading panicles of rush-like flowers col- 

 lected into small tufts. L. spicata is a sub- 

 alpine species a few inches high, having 

 its flowers in a nodding spike, which is 

 somewhat compound at the base. There 

 are many foreign species. [C. A. J.] 



LUZURIAGA. A genus of Liliacece from 

 Chili and Peru, consisting of branched un- 

 dershrubs, creeping on the stems of trees, 

 and adhering to them by rootlets, having 

 alternate leaves, and solitary axillary pe- 

 duncles bearing umbels of yellowish-white 

 flowers with purple dots ; the perianth six- 

 leaved, spreading and deciduous ; the sta- 

 mens six ; and the berry three-celled, with 

 two seeds in each cell. [J. T. S.] 



LYALLI A. A genus of Portulacacece, con- 

 sisting of a small undershrub from Kergue- 

 len Land, with somewhat the habit of Ly- 

 copodium Sclago, the stem, however, being 

 much branched, with imbricated adpressed 

 leaves, small solitary terminal flowers with 

 afour-parted calyx, and a one-celled subglo- 



bular uti-icular fruit with three seeds, two 

 of which are abortive. [J. T. S.] 



LYCASTE. The orchids now associated 

 in this genus were formerly referred to 

 Maxillaria, from which they are well distin- 

 guished by the two pairs of pollen-masses 

 being seated on a long caudicle attached 

 to a small roundish gland; while from the 

 other allied genera they are distinguished 

 by the middle of the lip being furnished 

 with a transverse fleshy entire or notched 

 appendage. They number a score or more 

 of species, exclusively tropical American ; 

 but some, being found in the cool mountain 

 regions, are suited for growing in green- 

 houses or even in dwelling-rooms, and of 

 these L. Skinneri, decidedly the finest of 

 I the genus, is the best example. The Ly- 

 j castes have short unjointed pseudobulbs, 

 i and plicate leaves. Their flowers, borne 

 J singly upon the top of stalks rising from 

 I the base of the pseudobulbs, are showy 

 ! and often of large size, with their sepals 

 j and petals frequently dissimilar, and with 

 | two of the former combined at the base and 

 protruded in front like a chin. [A. S.J 



LYCHNIDE DES JARDINS.. (Fr.) Lych- 

 nis coronaria. — LACINIEE. Luc'hnis 

 Flos-cuculi. — ROSE DU CIEL. Viscaria 

 Coeli-rosa. 



LYCHNIS. The Campion, a genus of 

 Caryophyllacew, distinguished by having 

 five styles. As this character is artificial, 

 various attempts have been made to divide 

 the genus into others, but in many in- 

 stances the proposed divisions are founded 

 on characters as artificial as those which 

 are assigned to the group as a whole. The 

 following may be taken as genera or sub- 

 genera:—!. Those in which the capsule 

 opens by as many teeth as there are 

 styles :—Eulychnis, calyx membranous in 

 front ; capsule septicidal ; seeds stalked, 

 rough with small tubercles. The Scarlet 

 Lychnis (L. chalcedonica) and the Ragged 

 Robin (L. Flos-cuculi) with pink flowers are 

 examples of this. Petrocoptis differs from 

 the last only in having the seeds sessile 

 and quite smooth, as in L. pyrenaica, a 

 white-flowered species. Viscaria, distin- 

 guished from the two preceding by the 

 capsule splitting loculicidally ; to this be- 

 long two British species, L. Viscaria and L. 

 alpina, both having rose-coloured flowers. 

 Coronaria, in which the calyx is thickened 

 in fruit ; the Rose Campion (£. coronaria) 

 is a good example. Agrostemma, same as 

 in the last, but without the scale-like ap- 

 pendages which occur at the base of the 

 limb of the petals, forming the so-called 

 crown ; the Corn Cockle (L. Githago), and a 

 closely allied species L. gracilis, axe the only 

 species which answer to this character. 

 2. Those in which the capsule opens by 

 twice as many teeth as there are styles; 

 nearly allied to Silene :—31elandrium, calyx 

 teeth regular ; calyx ovoid, with the veins 

 not prominent in fruit, as in L. vespertina 

 and L. dioica, the common wild Campions, j 

 Wahlbergella, like the last, but the calyx | 

 teeth are combined in pairs, and the petals
