LIRlOPE (named after the nymph Liriope). Hcema- 

 )racete. A tender, bulbous plant from China, growing 

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

 ?ertopping the Ivs., which bear from July to September 

 * many as 90 violet-colored fls. in a spike-like raceme 

 -12 in. long and 1 in. wide. The fls. are less than % in. 

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

 iceme. They vary from dark purple through violet to 

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

 y the yellow anthers. The genus has only one species 

 ad has been referred to 5 different families. The plant 

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

 erianth tube, and hypogynous stamens. It is procur- 

 ble through Dutch bulb "growers, and should perhaps 

 e grown in the greenhouse the year round. 

 spicata, Lour. (L. graminifdlia , Baker). Lvs. all 

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

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

 vary 3-celled. B.M. 5348, B.R. 7:593, and L.B.C. 7:694, 

 11 as Ophiopogon spicatus. Var. densifldra (L. gra- 

 nnifolium densiflorum, Hort. Van Tubergen) is pre- 

 umably the best form. ^y. M. 



LISlANTHUS (Greek, smooth flower). Gentianacece. 

 "he choice and rare plant known to catalogues as L. 

 'tussellianus is one of the largest-flowered species of 

 he Gentian family. It is a tender annual from Texas 

 md Mexico, and grows 1% ft. high, producing its 

 '-lobed, purple, dark-eyed fls. in summer and fall. Un- 

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

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

 )een known to last three weeks. The proper name of 

 ;his plant is Eustoma Russelliana. In Lisianthus, the 

 )vary appears to be 2- celled, because the placentae are 

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

 placentae are separated from each other by a consider- 

 ible space. Lisianthus has about 60 species, all tropical 

 American; Eustoma only 2 species. 



Russellianus, Hook. (Properly Eustdma fiusselidnum, 

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

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

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

 obovate, spreading ; stigma of 2 very large, green, velvety, 

 spreading plates: pod oblong; seeds minute, pale 

 brown. B.M. 3626. G. C. 111. 4: 240. R.H. 1863- 

 51 and 1881, p. 189. w M 



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 

 may 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 L HARRIS. 



LISSOCHILUS (Greek, smooth Up). Orchid- 

 dceie. This genus contains about 30 species dis- 

 persed in tropical and S. Africa. Some of them 

 are very handsome, but they seem to be little cultivated 

 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 Ivs. 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 may be grown in a compost of fibrous 

 loam, leaf -mold 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. 

 Krebsii, 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 May to 

 Oct., the fls. remaining a long time. Natal. B.M. 5861.

L. giganttus, Welw. & Reichb. f. A gigantic orchid whose Ivs. 

 are said to grow to a length of 8 ft., with flower spikes twice as 

 high: sepals linear, curled backward; petals oblong-quadrate, 

 1% in. across, pinkish rose; labellum 3 in. long, with a long 

 spur middle lobe trowel-shaped, purple, striped with darker 

 lines. Congo. G.C. III. 3:617. S.H. 2:355. I.H. 35:53. -i. Hors- 

 fallii, Batem. A robust plant, with plicate Ivs. 2-3 ft. long and 

 5-6 in. broad, sharp-pointed: flower stalk twice the length of 

 the Ivs., with many large fls. 3 in. in diameter: sepals reflexed, 

 rich purple-brown on the upper side: petals much larger, almost 

 square, white, suffused with rose. B.M. 5486. Handsomer than 

 the first. L. rbseus, Lindl. Lvs. broad and stiff: stem 3-4 ft. 

 high : sepals brown ; pe als and labellum fine rose-colored. 

 B.R. 30 : 12. Also a showy plant. L. speciosus, R. Br. Pseudo- 

 bulbs nearly underground : Ivs. dark green, ensiform : scape 

 2-4 ft. high, with fragrant fls. 2 in. across: sepals small, green, 

 reflexed; petals large, yellow; lip mostly yellow, apparently 

 on the upper side, due to the inversion of the fls. June, 

 July. Cape. B.R. 7:573 (erroneously numbered 578). P.M.B.

LISTfiRA (after Martin Lister, 1638 ( ? )-1712) . Orchid- 

 dcece. Small, slender, erect herbs, with fibrous or some- 

 times fleshy roots, bearing a pair of opposite green Ivs. 

 near the middle, and 1 or 2 scales near the base of the 

 stem: fls. small, spurless, in a terminal raceme; sepals 

 and petals similar, spreading or reflexed ; labellum rather 

 longer, narrow, entire or 2-lobed. About 10 species, na- 

 tives of the north temperate zone. 



convallarioides, Torr. Stem 4-10 in. high, with smooth, 

 round-oval, obtuse, cuspidate Ivs. : raceme 2-3 in. long, 

 bearing 3-12 greenish yellow fls. June-Aug. In woods,
