STYLOMA (name refers "to the large indurated 

 styles"). Palmacex. A genus very recently proposed 

 by O. F. Cook for the Pacific island palms heretofore 

 referred to Pritchardia (Journ. Wash. Acad. Sci., 1915, 

 p. 241). Pritchardia pacijlca under this disposition 

 becomes Styloma pacifica, Cook; and the other species 

 on page 2810, Vol. V, become S. Gaudichaudii, S. 

 Marlii, S. pericularum, and S. Tkurstonii, Cook. He 

 keeps Pritchardia Wrightii distinct under Colpothrinax. 



3741. Stylophorum 

 diphyllum. (XJi) 



STYLOPHORUM (Greek, style and bearing, in refer- 

 ence to the persistent style). Papaverac&e . Hardy, 

 perennial herbs, with stout rootstocks and yellow- sap: 

 Ivs. radical, pinnatifid or none; cauline few, lobed or 

 cut: fls. yellow or red; peduncles elongated, solitary or 

 somewhat fascicled; buds nodding; sepals 2; petals 4; 

 stamens many; ovary 2 4-placentae : caps, frequently 

 stipitate, ovoid, oblong or linear, dehiscent from the 

 apex to the base. Three species, according to Fedde, 

 one from N. Amer., the other two from China. 



diphyllum, Nutt. (Papaver Stylophorum, Hort.). 

 CELAXDIN-E POPPY. Fig. 3741. A hardy perennial 



about 1 ft. high, forming large clumps: st. with 2 Ivs. at 

 the summit: Ivs. light green, pinnately parted: fls. 

 yellow, 2 in. across, in clusters of 3-5. May, June. 

 "Moist shade, W. Pa. to Wis. and Ark. B.B. 2:102. 

 J.H. III. 34:475. Gn. 65, p. 283. An attractive plant 

 of easy cult, in any rich, rather loose, moist soil in 

 either shade or open, but preferably in partial shade. It 

 is easy to transplant. F w BARCLAY. 



STYLOPHYLLUM (Greek, style or column and leaves). 

 Crassulacex. A genus separated from Cotyledon and . 

 composed mostly of new species: basal Ivs. linear, elon- 

 gated, base sometimes broad clasping: calyx 5-lobed, 

 the lobes ovate, equal and small; corolla campanulate, 

 not angled, white, red, or yellowish, the lobes broad, 

 thin, and spreading, united below into a tube : carpels 5, 

 united below, generally strongly spreading as in Sedum. 

 Twelve species all from Calif. S. Orcuttii, Rose. 

 Rather stout and very glaucous, woody at base: Ivs. 

 linear: calyx-lobes obtusish; corolla-tube shorter than 

 the calyx, the lobes rather broad and somewhat keeled, 

 rose-colored, not at all tinged with yellow. S. Calif . 

 and adjacent islands. This plant was distributed as 

 Cotyledon attenuata, which is probably a different 

 species. 



STYRAX (ancient Greek name of Styrax officinalis). 

 Styracacese. STORAX. Ornamental woody plants chiefly 

 grown for their handsome flowers. 



Deciduous or evergreen trees or shrubs more or less 

 stellate-pubescent : Ivs. short-stalked, exstipulate, more 

 or less covered, like the infl., with stellate hairs: fls. 

 white; calyx campanulate, obscurely 5-toothed or 

 truncate; petals 5, connate only at the base; stamens 10, 

 inserted at the base of the corolla and usually somewhat 

 connate below; ovary superior, often united at the base 

 with the calyx, 3-loculed at the base, 1-loculed at the 

 apex; style slender: fr. a drupe, mostly subglobose, 

 fleshy or oftener dry with dehiscent pericarp, 1-2- 

 seeded, with large, subglobose seeds. About 100 

 species in the tropical, subtropical, and warmer tempe- 

 rate regions of Amer., Asia, and Eu. There is a mono- 

 graph by Miss J. Perkins in Engler, Pflanzenreich 

 (IV. 241), Styracaceae, pp. 17-88 (1907). S. Benzoin 

 yields the benzoin, a balsamic exudation of the wounded 

 tree ; storax, a similar gum-resin, was formerly obtained 

 from S. officinalis, but the storax of today is a product 

 of Liquidambar. 



The storaxes are handsome shrubs of graceful, usu- 

 ally loose and spreading habit with numerous white and 

 mostly fragrant, often pendulous, flowers in racemes or 

 few-flowered clusters, followed by rather insignificant 

 subglobose drupaceous fruits. S. japonica and S. 

 Obassia are the hardiest and stand the winter in shel- 

 tered positions as far north as Massachusetts. S. 

 americana is somewhat tenderer; S. grandifolia is hardy 

 about Philadelphia and S. Wilsonii is probably of the 

 same hardiness; S. officinalis is hardy only South. They 

 are well adapted for borders of shrubberies or as single 

 specimens on the lawn, and thrive best in a light, porous 

 soil. Propagation is by seeds which are usually pro- 

 fusely produced in cultivation, sown soon after ripening, 

 and by layers sometimes grafted on Halesia Carolina; 

 S. japonica and S. americana may also be grown from 

 cuttings, but usually only a small percentage will root. 



A. Fls. in many-fld. racemes: Ivs. 2-10 in. long. 



B. Young branchlets, petioles, and racemes grayish- 

 tomentose. 



grandifdlia, Ait. Shrub, 4-12 ft. high: Ivs. oval to 

 obovate, shortly acuminate, usually narrowed toward 

 the base, denticulate or almost entire, glabrous above, 

 grayish-tomentose or -pubescent beneath, 2V- in- 

 long: fls. fragrant, in loose racemes 3-6 in. long or some- 

 times in clusters; corolla fully H m - l on g> vrith spread- 

 ing, oblong petals: fr. subglobose, about ^in. across.
