Styrax. STYRACACEtE. 71 



above, pale and pubescent beneath, tardily deciduous, or far south more persistent : flowers 

 in sessile fascicles from the axils of the pi'eceding year, 6 to 16 in a cluster, scaly-bracteate, 

 the scales deciduous : calyx-tube turbinate : petals oblong, obtuse, barely connected at 

 base and bearing the stamen-clusters : ovary 3-celled : fruit nut-like, oblong, half inch or 

 less long. — Linn. Trans, i. 176; Willd. Spec. iii. 1436. Hopea tinctoria, L. Mant. 105; 

 Michx. f. Sylv. iii. 9. — In rich soil, Delaware ( Commons) to Florida and Louisiana ; fl. spring. 

 Flowers fragrant. Leaves sweet to the taste and in autumn greedily devoured by cattle 

 and horses (hence called Hokse-Sugar) ; also used for yellow dye. 



2. HAL£1SIA, Ellis. Snowdrop or Silver-bell Tree. (Commem- 

 orates Stephen Hales of England, author of Vegetable Statics, &c.) — Small trees 

 of the Atlantic United States ; with partly stellate soft pubescence : leaves 

 rather large, ovate-oblong, acuminate, more or less depticulate, slender-petioled, 

 deciduous ; flowers showy, drooping on slender pedicels, in fascicles (or rarely 

 very short racemes) from the axils of fallen leaves of the preceding year, pro- 

 duced in spring at leafing-time ; corolla white. Thin testa of the seed adherent 

 to the pericarp ; the delicate inner coat adherent to the albumen. — {Pterosfi/rax, 

 Sieb. & Zucc, of Japan, referred to this genus by Bentham and Hooker, although 

 nearly related, is better kept distinct, on account of the terminal paniculate inflo- 

 rescence, quinary flowers, and thinner small fruit.) Ellis in Phil. Trans, li. t. 22 ; 

 L. Gen. no. 596. 



H. diptera, L. Tall shrub or small tree : leaves ovate or inclined to obovate, when full- 

 grown thinnish and venulose-reticulated (4 to 6 inches long) : corolla three-fourths inch 

 long: stamens 8 to 16, mostly 8, sometimes free: ovary rarely 4-celled : fruit oblong (2 

 inches long), 2-winged ; its strongly angled body tapering into a long stipe within the 

 wing. — Spec. ed. 2, 636; Cav. Diss. vi. t. 187; Lodd. Cab. 1. 1172. H. reticulata, Buckley 

 in Froc. Acad. Fhilad. 1860. — Rich woods, Georgia and Florida to Louisiana. Flowers 

 larger and more numerous and showy than in the next. 



H. tetraptera, L. Small tree (or in the mountains even a large tree) : leaves oval or 

 ovate-oblong : corolla half inch long : stamens 10 to 16 : ovary 4-celled : fruit ellipsoidal, 

 equally 4-wing-angIed, over an inch long. — (Catesb. Car. i. t. 64.) Lam. 111. t. 204 ; Cav. 

 1. c. t. 186 ; Bot. Mag. t. 910 ; Lodd. Cab. t. 1173. — Woods and along streams, W. Virginia 

 and Illinois to Florida, mostly along and near the mountains. 



H. parviflora, Michx. Foliage of //. tetraptera, but smaller : corolla 4 or 5 lines long : 

 fruit an inch or loss in length, narrowly 2-winged, the oblong-clavate body with stipe 

 included in the acute base of the wing. — Fl. ii. 40, not Lindl. Bot. Reg., wliich is Styrax 

 Americana. — Georgia and Florida. 



3. STYRAX, Tourn. Storax. (Greek 2^Tvna^, ancient name of the tree 

 which yields to otvqu^, storax.) — Shrtibs or small trees, the pubescence when 

 present scurfy or stellular. Leaves deciduous, at least in our species ; the flowers 

 (in spring) racemose, subcorymbose or somewhat cymulose, or sometimes solitary, 

 from the axils or summit of the branchlets. Corolla white, in ours campanulate 

 or more open, of petals distinct to the base or nearly so, soft and tomentulose or 

 puberulent, at least outside. Ovary 3-celled at base, with a thick placenta, which 

 divides and becomes obsolete at the summit. A widely dispersed genus, chiefly of 

 warm regions. — Gray, Mem. Am. Acad. 1. c, Proc. vi. 326, & Man. ed. 5, 309 ; 

 Benth. & Hook. 1. c. 



# Petals nearly valvate in the bud, a third to barely half inch long. 



S. Americana, Lam. Shrub 4 to 8 feet high, glabrous or nearly so throughout : leaves 



small (1 to 3 inches long), bright green, commonly entire, oblong or oval, mostly acute at 



both ends, often acuminate : flowers single or in very few-flowered racemes, nodding : 



peduncles or branchlets minutely glandular, not hoary : 5-toothed calyx and sometimes
