288 EVPHOTtBIACEM 



racemes terminal, generally solitary, erect, sHorter than tLe 

 leaves ; flowers solitary, a few female ones mixed with many 

 male ones, small, of a pale yellowish-green ; bracts 3-fold, one- 

 flowered^ on the inside of each of the small lateral bracts is a 

 round permanent gland^ as in Scsamum indicum ; male calyx 

 deeply 5-cleft, petals six, smaller than the calyx, very woolly; 

 filaments twelve^ distinct, nine in the circumference and three 

 in the centre, woolly towards the base; female calyx and corol 

 as in the male ; stamens none ; germ globular ; styles three, each 

 divided into two very long, variously bent segments ; capsules 

 globular, fleshy, six-furrowed, tricoccous. [Roxb.) 



The root is twisted, often somewhat flattened, bark thickish, 

 externally light-brown and scaly, internally yellowish, mottled 

 with brown, substance compact and resinous, odour highly 

 aromatic, taste peppery and camphoraceous* Wood white, soft. 



Microscopic stnictnre. — Sections of the bark show that the 

 epidermis consists of about five rows of elongated cells placed 

 horizontally; their walls are much thickened by a dark-browu 

 deposit, which produces a patchwork appearance. The paren- 

 chyma is loaded with large globular or oval highly refractive 

 bodies of a yellowish colour ; there are also numerous dark 

 purplish-brown particles, which are sometimes single but 

 usually arranged in irregular concentric rows ; they appear to 

 be due to a deposit in the vascular system of a resinous nature* 



Chemical comjyosition. — The fresh root-bark was contused, and 

 exhausted with warm 80 per cent, alcohoh The tincture was 

 of a red colour. The alcoholic extract was mixed with water 

 and agitated with petroleum ether, when reddish flocks 

 separated. The solution was acid in reaction. The petroleum 

 ether solution left on spontaneous evaporation a transparent 

 viscid yellow residue, possessing a camphoraceous and pepper- 

 like odour and taste. With the exception of some white flocks, 

 the extract was soluble in cold alcohol with acid reaction ; the 

 Bolution afforded no coloration with ferric chloride.
