SOPHRONITIS (Greek, modest). Orchidaceae. Dwarf 

 epiphytic orchids, cultivated on account of their neat 

 habit and brilliantly colored flowers. 



Pseudobulbs small, with 1 or rarely 2 small flat Ivs.: 

 fls. from the top of the pseudobulbs, brightly colored; 

 sepals and petals nearly equal, spreading; labellum with 

 a broad middle lobe and small erect side lobes, the base 

 leading into a cavity in the wall of the ovary; column 

 short, the stigmatic surface covering 2 wing-like pro- 

 jections at its summit; pollinia 8. About 6 species, 

 closely related to Laelia, Cattleya, and the like; Brazil. 



These plants, and also sophrocattleyas and sophro- 

 laelias, thrive in the temperature of the cattleya house. 

 In growing season, give a moderate supply of water and 

 plenty of fresh air. Rest them at 50 to 55, and water 

 sufficiently to keep them from shriveling. Grow them 

 in shallow pots with plenty of drainage, and a thin 

 layer of fine turfy fern-root, using no sphag- 

 num. (Wm. Mathews.) 



grandifldra, Lindl. (S. cocdnea, Reichb. f.). 

 Pseudobulbs clustered: Ivs. about 2 in. long, 

 elliptic: fls. solitary, on short peduncles, 1 J^-4 

 in. across, brilliant scarlet, often with a shade 

 of orange, with an orange labellum; sepals 

 oblong-lanceolate; petals broadly elliptic; 

 labellum narrow, with folded sides. Flowers 

 during the whole winter. Organ Mts. B.M.

cernua, Lindl. Very small plants with a creeping 

 rhizome bearing 1-lvd. pseudobulbs: Ivs. ovate, thick 

 and leathery, a little over an inch long: fls. 4-8, on a 

 st. from the axils of the Ivs., bright scarlet or reddish 

 orange, with an orange lip; sepals and petals ovate; 

 labellum ovate-acuminate, shorter, concave. Winter.

violacea, Lindl. One of the smallest of cult, orchids: 

 pseudobulbs ovoid, 1 in. long: Ivs. linear, 2-3 in. long: 

 fls. bright rose, about 1 in. diam.; sepals and petals 

 oblong-lanceolate, acute; labellum rhombic-obovate, 

 flat. Winter. Organ Mts., Brazil. B.M. 6880.

SORBARIA (derived from Sorbus: the leaves resem- 

 ble those of the mountain-ash). Syn., BasiRma. 

 Rosaces. Ornamental woody plants chiefly grown for 

 their large panicles of white flowers and the handsome 

 pinnate foliage. 



Deciduous shrubs: Ivs. alternate, odd-pinnate, with 

 serrate Ifts., stipulate: fls. in terminal panicles; sepals 

 and petals 5; stamens 20-50: carpels 5, opposite to 

 the calyx-lobes, partly connate, dehiscent at the 

 ventral suture, with several seeds. Eight species in E. 



Asia. Formerly usually united with Spiraea but easily 

 distinguished by the stipulate, pinnate Ivs. and the 5 

 carpels being opposite to the sepals. 



The sorbarias are very handsome upright shrubs with 

 rather large bright green pinnate leaves and small white 

 flowers in large and showy panicles appearing in sum- 

 mer and followed by small capsular fruits; the panicles, 

 however, after the flowers have faded and dried up, 

 become rather unsightly and should be removed. S. 

 sorbifolia is hardy North and S. steUipila, S. assurgens, 

 and S. arborea have proved hardy at least as far north 

 as Massachusetts, while S. Aitchisonii is somewhat 

 tenderer and S. Lindleyana still more so. They are well 

 adapted for borders of shrubberies and woods or for 

 planting on banks of brooks or rivers, but should not 

 be brought together with slow-growing and delicate 

 shrubs, as they spread in suitable soil rather rapidly by 

 means of suckers and are likely to overcrowd other 

 plants. The handsome bright green foliage appears 

 very early in spring. They are 

 all much alike in habit, but 

 flower at different times from 

 June to September, beginning 

 with S. sorbifolia, followed in 

 order by S. stettiptta, S. assur- 

 gens, S. arborea, and S. Aitch- 

 isonii which usually continues 

 flowering until September. 

 They grow best in a somewhat 

 moist and rich soil and thrive 

 also in partly shaded situations. 

 Propagation is "by hardwood 

 cuttings; also by root-cuttings, 

 suckers, and seeds, like spirea.

 rate, %in. or more wide.
