LISIANTHUS 



LITCHI

ft. high, producing its 5-lobed, purple, dark-eyed fls. 

 in summer and fall. Under 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. According to F. L. Harris, in the Old World it 

 is usually treated as a cool greenhouse subject, being 

 sown in early spring for summer and autumn bloom. 

 The seed should be sown carefully, 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 transplanting from the seed- 

 beds, use small pots. When larger plants are needed, 

 place them in a light, airy place and give generous 

 bottom heat. For soil, use good loam, sand and well- 

 rotted manure. WILHELM MILLER. 



LISSOCHILUS (Greek, smooth lip). Orchiddcex. 

 Terrestrial herbs, some of which are very handsome, 

 but they seem to be little cultivated in America, only 

 a single species being advertised here. 



The plants are 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: Ivs. plicate and prominently veined, long and 

 narrow: sts. very short, leafy, finally thickened into 

 pseudobulbs: raceme simple; scape long, stout, sheathed 

 but leafless, growing beside the pseudobulb; labellum 

 spurred or saccate, joined to the base of the column. 

 About 30 species dispersed in Trop. and S. Afr. 



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 sts. 

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

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

 oblong, bent back, green, with dull purple blotches; 

 petals much larger, golden yellow; lip yellow, pendu- 

 lous, saccate between the small, rounded lateral lobes; 

 middle lobe orbicular, notched in front. Flowers from 

 May to Oct., the fls. remaining a long time. Natal.

LITCHI (Chinese name). Sapinddcese. One species 

 in China, and cultivated elsewhere for its edible fruit. 



By some botanists included in Nephelium, but the 

 definition is probably clearer if Litchi and Euphoria 

 are kept distinct, both of which differ from Nephelium 

 in having the seed-covering or arillus free from the 

 seed rather than grown to it.
