LIRiOPE (named after the nymph Liriope). Bwma- 

 •lordcew. A tender, bulbous plant from China, growing 

 a foot high, with grass-like foliage and 1 or 2 scapes 

 overtopping the lvs., which bear from July to September 

 as many as 90 violet-colored tls. in a spike-liiie raceme 

 li-12 in. long and 1 in. wide. The Ws. are less than K in. 

 :icross, 6-parted and arranged in groups of 3-5 along the 

 raceme. They vary from dark purple through violet to 

 whitish. The deepest color is the finest, and is set off 

 by the yellow anthers. The genus has only one species 

 and has been referred to 5 different families. The plant 

 iias a short, thick, stoloniferous rhizome, no stem: no 

 perianth tube, and hypogynous stamens. It is procur- 

 able through Dutch Ijulb growers, and should perhaps 

 be gi'own in the greenhouse the year round. 



spicita, Lour. {L. graminifbUa, Baker). Lvs. all 

 radical, linear-lanceolate, obtuse, 3-nerved, with a few 

 brown scales at the base: stamens 6: style columnar: 

 ovary .S-celled. B.M. 5348, B.B. 7:593, and' L.B.C. 7:(i9i, 

 all as Ophiopogon. spicatiix. — Var. densifl6ra {L. grn- 

 niinifoUnm densiflorum, Hort. Van Tubergen) is pre- 

 sumably the best form. W. M. 



LISIANTHTJS (Greek, smootK flower). GmHunilcea-. 

 The choice and rare plant known to catalogues as Ij. 

 Russellianus is one of the largest-flowered species of 

 the Gentian family. It is a tender annual from Texas 

 and Mexico, and grows l}i ft. high, producing its 

 5-lobed, purple, dark-eyed rts. in summer and fall. Un- 

 der favorable conditions the fls. are 4 in. across, as 

 many as 10 or 11 on a plant, and individual blossoms have 

 been known to last three weeks. The proper name of 

 this plant is Eustoma Bnsftelliana. In Lisianthus, the 

 ovary appears to be 2 celled, because the plaeentte are 

 connivent in the middle of the cell, but in Eustoma the 

 placentie are separated from each other by a consider- 

 able space. Lisianthus has about 60 species, all tropical 

 American; Eustoma only 2 species. 



EusselUanuB, Hook. ( Properly _fi'HsM»m Busselidniim, 

 G. Dou). Glaucous: stem simple, or with a few opposite 

 branches: lvs. opposite, connate, ovate or ovate-oblong, 

 .3-5-ncrved : fls. panicled, as large as a tulip ; lobes 

 obovate, spreading; stigmaof 2 very large, green, velvety, 

 spreading plates: pod oblong; seeds minute, pale 

 brown. B.M. 3(;20. G. C. HI. 4: 240. R.H. 1803-

This fine plant is difficult to grow in America. 

 In the Old World it is usually treated as a cool 

 greenhouse subject, being sown in early spring 

 for summer and autumn bloom. The writer has 

 not grown it for thirty years, but in view of the 

 renewed interest in this plant, his experience 

 miy be useful. The seed should be sown care- 

 fully, and at every stage of the plant'.s growth 

 over-watering should be guarded against. The 

 seedlings are very likely to damp-off. When they 

 are ready for trans-planting from the seed-beds, 

 use small pots. When larger plants are needed, 

 place them in a light, airy place and give gener- 

 ous bottom heat. For soil, use good loam, sand 

 and well-rotted manure. p, j^ Harris 



LISSOCHlLUS (Greek, smooth lip). Orchid- 

 clcae. This genus contains about 30 species dis- 

 per.sed in tropical and S. Africa. Some of them 

 are very handsome, but they seem to be little cullivated 

 in America, only a single species being advertised here. 

 The plants are terrestial herbs, distinguished from their 

 near allies by the dissimilarity of the sepals and petals, 

 the latter being much larger and wider and usually of 

 a different color. The lvs. are plicate and prominently 

 veined, long and narrow: stems very short, leafy, finally 

 thickened into pseudobulbs: raceme simple: scape long, 

 stout, sheathed but leafless, growing beside the pseudo- 

 bulb : labellum spurred or saccate, joined to the base of the 

 column. The plants maybe grown in a compost of fibrous 

 loam, leaf-moid and sand. During the growing season 

 they require plenty of water, but during three months 

 of winter they should be allowed to rest and be kept dry. 

 Kr^baii, A. Rich. Lvs. in tufts on the young stems, 

 elliptic-lanceolate, 8-12 in, long : scape 2-3 ft. high : 

 raceme 12-18 in. long, with 20-30 fls.: sepals linear-ob- 

 long, bent back, green, with dull purple blotches; petals 

 much larger, golden yellow; lip yellow, pendulous, sac- 

 cate between the small, rounded lateral lobes; middle 

 lobe orbicular, notched in front. Flowers from Blayto 

 Oct., the fls. remaining a long time. Natal. B.M. 5801.
