LUZULA (Latin lux, Iif;ht, in diminutive derivation, 

 from some fanciful attribute or interest). Juncarcse. 

 Wood Hush. About forty spetnes of gr;uss-Iike (jr rush- 

 like, often cesjiitose, perenni;il herbs of witle distribu- 

 tion in temperate and frigid regions, some of them 

 adapted to borders and for colonizing. Several species 

 are native in the United Stati« and Canada, but none 

 of them seems to be listtni in the trade; two Euroi)ean 

 species are offered abroafl. By some, the name Jun- 

 coides is used in place of Luzula. 



These are i)lants of mostly inconspicuous green or 

 scarious fls. (sometimes white) in umbel-like, panicu- 

 late, cor^Tnbo.se or congested infl., the fls. always 

 bracteolate; perianth parts distinct, glumaceous; 

 stamens usually 6; ovarj- 1-celled: fr. a dry 3-seeded 

 caps.: Ivs. soft, usually hairy or webby: dry ground. 

 Juncus, to wliic-h the genus is closely related, differs in 

 its mostly 3-celled and many-seeded caps. 



sylvatica, Gaud. (L. vidiima, DC. L. syhestris, Hort. 

 Junantks sylvdticum, Kuntze). Rhizome woody: st. 

 12-18 in. or more high: Ivs. linear-lanceolate, hairy- 

 edged, .shining, striate: panicle double-compound, 

 much exceeding the If .-like bracts; perianth-segms. 

 bristle-pointed; filaments very short. Eu. — There is a 

 fonn with variegated (striped?) foliage. 



nivea, DC. {Junaruies nlvcum, Kuntze). Fls. pure 

 white, large, in thick panicles that are shorter than the 

 If.-bracts; filaments about equaling the anthers: plant 

 12-18 in.: Ivs. linear, hairy on margin. Eu., Alps. — ■ 

 Useful in dry bouquets. L H. B. 



LYCASTE ("fanciful name). Orchidacex. Epiphytic 

 and tJ'rrestrial orchids; very popular as greenhouse 

 subjects. 



Pseudobulbs ovate or oblong-ovate, bearing 1 to 

 several plicate Ivs. at the summit, and sheathing Ivs. 

 from the base: sepals subsiniilar, spreading, the lateral 

 pair united with the ba«e of the column and forming a 

 spur-like chin or mentiim; petals smaller, projecting 

 forwarfl, with the tips t)ften recurved; labfdlum ii-lobed, 

 the lat<;ral lobes erect, miiidle lobe ascending or re- 

 curved, with a fleshy, tongue-like callus on the disk; 

 Rcillinia 4. — About 30 species, all natives of S Amer., 

 lex., and the \V. Indies. The fls. are freely j)roduce<l 

 and remain in good condition on the plant for several 

 weeks. Thej' are norrtially borne singly on erect or 

 8ub-crc<;t bracted scafX's, but sometimes twin-fid. stalks 

 occur. In Lycaste the scape ari.ses from the very young 

 leafy axis, which does not develop until several months 

 later. The wiajje, therefore, ai)pears from the base of the 

 bulb. Among the spjccies, L. Skinneri is a favorite 



orchid with growers. The species of Jjyciiste are very 

 distinct from each other and do not fall readily into 

 n:Uur;il (i,roups. The arr:iiigeiuent in the key is jiurely 

 luiificial, ;iiid does not indicate close relationship among 

 the species grouped together. 



The geiuis Lyc:isle is clo.sely allied to Maxillaria and 

 ha-f a simihir geiigrapliic;d range, being foimd from 

 Mexico and (he West Indies to Peru and .southeastern 

 Brazil. Nt>hvithslanding this wide distribution, how- 

 ever, they ri^adily subject, themselves to one general 

 mode of treatmenl, and in;iy be grown in a bright cool 

 portion of the cattleya or warm end of the odontoglos- 

 smn department, where they .should receive plenty of 

 iitdirect .solar light, moisture anil suthcient ventilation 

 to ensure an active atmosphere. During winter, the 

 night temperatiu'c should range from M° to .5.5° Fahr. 

 and that of the <lay from 60° to tj.5°, or a few degrees 

 higher, with sun heat and ventilation. In summer, the 

 air should be as cool as iiossible, and contain plenty of 

 moisture. When lycastcs are growing they need a good 

 sujjply of water at tht^ roots, and shoukl never be allowed 

 tt) remain dry for a long time, even when at rest. Light 

 syringing overhead is beneficial at all times in bright 

 weather when air can be admitted. The deciduous spe- 

 cies, however, must be carefully watered when at rest, 

 for it must be remembered that in casting their foliage 

 they lose most of their active radiating surface, thus 

 reducing evaporation to a minimum. — For special treat- 

 ment, they may be divided into three groups, L. aromat- 

 ica, L. costala and L. Idragona forming good types. 

 The L. aromalica section embraces, besides the type, L. 

 ainilida, L. crucnln, L. Dcppci, L. lasioglnssa, L. macro- 

 hiilban and kindred sorts, all more or less deciduous. 

 These grow best in pots in a mixture of equal parts 

 chopped peat fiber and sphagnum moss, with a small 

 quantity of leaf-mokl added. About one-third of the pot 

 space should be devoted to drainage of broken charcoal 

 or potsherds, and the compost must be carefully and 

 rather firmly pressed in about the roots, leaving the 

 bixse of the pseudobulbs on a level with or a little below 

 the rim of the pot. The best time for transplanting is 

 just after the plants start into new growth, at which 

 time give a more abundant supply of water. — The L. 

 coslaUi group includes, besides the type, such species as 

 L. lanipes, L. locusta and L. Skinncri, which, excepting 

 the last, are but semi-deciduous, large-growing species. 

 They succeed best under pot culture, and should be 

 grown in a compost of about equal parts chopped sod, 

 from which some of the fine soil has been removed, and 

 decomposed leaves, adding a little chopped live sphag- 

 num to keep the soil porous and to retain moisture. 

 The compost should become nearly dry occasionally to 

 prevent it from becoming sour. — The L. Ictragona section 

 is small ; all arc sempcrvirent and grow best under basket 

 culture in porous material consisting of chopped peat 

 fiber and live sphagnum, well mixed and interspersed 

 with nodules of charcoal. The compost should be pres.sed 

 in moderately firm about the roots to keep the plant 

 steady, and newly imported pieces should be held in 

 place by copper or brass wire crossed between the p.seudo- 

 bulbs. — Lycaste stock is usually supplied by new impor- 

 tations, but plants may be increased by cutting throiigh 

 the rhizome between the pseudobulbs, two at least being 

 left to each piece. (Robert M. Grey.)
