STRYPHNODENDRON 



STURTEVANT 



trees with bipinnate foliage, numerous leaflets, and small 

 fls. borne in axillary, cylindrical spikes. Fls. sessile, 

 5-merous; petals often connate to the middle, valvate; 

 stamens none, free: pod linear, compressed, thick. 

 Here belong S. Guianense and S. floribundum, both of 

 which are known as Acacias, the latter as A. pulcher- 

 rima. Neither species is known to be cult, in America. 



STTTARTIA (in honor of John Stuart, Earl of Bute, a 

 patron of botany; 1713-1792). Sometimes spelled Stew- 

 artia. Ternstrcemidcece . Ornamental deciduous shrubs 

 or trees, with alternate, short-petioled serrate leaves 

 and large showy white flowers solitary on short stalks 

 in the axils of the leaves, followed by capsular fruits. 

 S. pentagyna and S. Pseudo-Camellia are hardy as far 

 north as Mass., while S. Malachodendron is tender 

 north of Washington, D. C. They are very desirable 

 ornamental plants, with handsome bright green foliage 

 which turns deep vinous red or orange and scarlet in 

 fall, and they are very attractive in midsummer with 

 their white cup-shaped flowers, which are in size hardly 

 surpassed by any others of our hardier shrubs. The 

 Stuartias thrive in deep, rich, moderately moist and po- 

 rous soil, preferring a mixture of peat and loam, and, at 

 least in more northern regions, a warm, sunny position. 

 Prop, by seeds and layers; also by cuttings of half- 

 ripened or almost ripened wood under glass. 



Five species occur in N. Amer. and E. Asia. Shrubs or 

 trees, with smooth flaky bark: fls. axillary or subtermi- 

 nal, with 1 or 2 bracts below the calyx; sepals and pet- 

 als 5 or sometimes 6, the latter obovate to almost orbic- 

 ular, usually concave, with crenulate margin, connate 

 at the base with each other and with the numerous sta- 

 mens; styles 5, distinct or connate: fr. a woody, usually 

 hirsute capsule, loculicidally dehiscent into 5 valves; 

 seeds 1-4 in each locule, compressed, usually narrowly 

 winged. 



A. Styles united: petals always 5. 

 B. Stamens purple, spreading : capsule subglobose.. 



Malachodendron, Linn. (S. Virginica, Cav.). Shrub, 

 6-12 ft. high: Ivs. oval to oval-oblong, acute at both 



August in the North). Va. and Ark. to Fla. and La. 

 Gn. 14:136; 18, p. 628; 34, p. 280. G.C. II. 8:433.- 

 This species has the largest and showiest flowers.

ends, serrulate, light green, pubescent beneath, 



in. long: fls. 2/^-3 in. across, with obovate spreading 



petals: seeds wingless, shining. May, June (July and 



2438. Stylophorum diphyllum (X %). 



BB. Stamens with whitish filaments, incurved : cap- 

 sule ovate, pointed. 

 C. Bracts beneath the calyx large and leaf-like. 



monadelpha, Sieb. & Zucc. Shrub or small tree: Ivs. 

 oval to oval-oblong, acute at both ends, remotely serru- 

 late, slightly pubescent beneath, light green, l%-2 % in. 

 long: fls. white, 1% in. across, with flat, spreading obo- 

 vate petals; anthers violet. Japan. S.Z. 1:96. This is 

 the least desirable species and probably as tender as the 



E receding; it is doubtful whether it is in cultivation, 

 pecimens recently introduced seen by the writer 

 proved to be the following species. 



cc. Bracts small, shorter than calyx. 

 Pseudo-Cam611ia, Maxim. (S. grandiflbra, Briot. S. 

 Japonica, var. grandiflbra, Hort.). Shrub, with up- 

 right branches, or tree attaining 50 ft. or more in Japan ; 

 trunk with smooth red bark, peeling off in great thin 

 flakes: Ivs. elliptic to elliptic-lanceolate, acute at both 

 ends, or often acuminate at the apex, thickish, bright 

 green, glabrous or nearly so beneath, 1/^-3 in. long: 

 fls. hemispherical, 2-2% in. across; petals almost orbic- 

 ular, concave, silky-pubescent outside; anthers orange- 

 colored: seeds 2-4 in each cell, narrowly winged, dull.

 Fig. 2437. Shrub, 6-15 ft. high: Ivs. ovate to oblong- 

 ovate, acuminate, usually rounded at base, remotely 

 serrate, sparingly pubescent and grayish green beneath, 

 2%-5 in. long: fls. cup-shaped, 2-3 in. across; petals 

 obovate, with wavy crenulate margin; stamens white, 

 with orange - yellow anthers : capsule ovate, pointed, 

 sharply 5-angled; seeds narrowly winged. July, Aug.
