 Derivation. The word sturax, applied to this plant by Theophrastus and E/ioscorides, is a mere 



alteration of assthirak, the Arabic name of S. omcinSle. 



Gen. Char., $c. Calyx permanent, campanulate, 5-toothed. Corolla monope- 

 talous, funnel-shaped, deeply 3 7-cleft, but usually 5- or 6-cleft, valvate in 

 aestivation. Stamens 10, exserted ; filaments monadelphous at the base, 

 adnate to the tube of the corolla. Anthers linear, 2-celled, dehiscing length- 

 wise inwardly. Ovarium superior, 3-celled, many-ovuled, erect. Style 1 . 

 Stigma obsoletely 3-lobed. Drupe nearly dry, containing a 1-celled, 1 3- 

 seeded nut. Testa of seed double ; inner cobwebbed, outer spongy. (Don's 

 Mill.) 



Leaves simple, alternate, exstipulate, deciduous ; entire or serrated. 

 Flowers racemose, bracteate, white or cream-coloured. Low trees or shrubs ; 

 natives of Asia or North America. 



They require a soil rather light than otherwise, on account of their hair-like 

 roots ; and to be placed against a wall, in the climate of London, when it is 

 intended that they should flower freely. In affinity, as well as in general ap- 

 pearance, this genus approaches near to that of Hales/a ; and there is such 

 a close general resemblance among all the allied species of S'tyrax, that they 

 may possibly be only varieties of one form. Seeds or layers. 



& 1. S. OFFICINA V LE L. The officinal Storax. 



Identification. Lin. Sp., 635. ; N. Du Ham., 7. p. 7. ; Don's Mill., 4. p. 4. 

 Synonymes. Lagomelia, Modern Greek ; Sturax kalamites, Ancient Greek 

 Engravings. Bot. Rep., 631. ; Bot. Cab., 928. ; and our fig. 1199. 



Spec. Char., $c. Leaves ovate, clothed with hoary hairs beneath, shining and 

 green above. Racemes simple and axillary, 5 6-flowered, 

 shorter than the leaves. Leaves about 2 in. long. Flow- 

 ers white. Drupe ovate globose. (Don's Mill.) A de- 

 ciduous shrub or low tree. Syria and the Levant. 

 Height 12 ft. to 15ft. against a wall; as bushes, in the 

 climate of London, seldom half so high. Introduced in 

 1597. Flowers white, resembling those of the orane, 

 but smaller ; June and July. Drupe ovate, greenish ; 

 ripe in October. 



It well merits a place against a wall, on account of the 

 beauty of its pure white flowers, and the great profusion 

 in which they are produced. A light sandy soil, rich 

 rather than poor, suits this species best ; and it is gene- 

 rally propagated by seeds obtained from the South of, 

 France. It will also grow by layers, and by cuttings. Its 

 rate of growth, for the first ten years, is not above 8 or 

 9 inches a year.
