CINCHONACE*:. 



Trunk straight, of considerable thickness and height. Branches 

 numerous, spreading. Bark of the trunk pretty thick ; the exterior 

 coating grey, light, spongy, cracking in various directions, and frequently 

 falling off; the middle coat brown, of a farinaceous nature, and as thick 

 as both the exterior and interior coats; the interior white. Leaves 

 opposite, oblong, entire, soft, downy, particularly on the under side; 

 veins simple, and frequently opposite, from 6 to 1 2 inches long, and 

 from 3 to 5 broad. Floral leaves, at the lower part of the ramifications 

 of the panicle, in shape like the rest, but much smaller, coloured, more 

 permanent, and bullate. Petioles round, downy, 2 or 3 inches long. 

 Stipules within the leaves, ovate-cordate, acutely serrate, erect, caducous. 

 Panicles terminal, large, generally with the lower ramifications decus- 

 sating. Flowers fascicled, small, greenish-white, exceedingly numerous, 

 exquisitely fragrant. Calyx superior, 5-toothed. Corolla funnel-formed, 

 downy ; tube long ; border 5-parted, with oval, spreading divisions, not 

 half the length of the tube. Filaments 5, short, inserted into the mouth 

 of the tube; anthers erect, i within the tube. Style twice the length 

 of the tube ; stigma capitate. Capsule oblong, crowned with the remains 

 of the calyx, about as thick as a field bean, but twice as long, 4-streaked, 

 marked with small white, elevated specks, 2-celled, 2-valved, opening 

 from the top. Placentae slender, angular, the length of the capsule, 

 affixed lengthways to the suture of the partition. Seeds from 6 to 12 

 in each cell, chestnut-coloured, imbricated, oblong, compressed, en- 

 larged all round by a membranous jagged wing, which at the base is 

 split up to the seed itself. Roxburgh. The 2 inner layers of bark possess 

 the bitterness and astringency of Peruvian bark, and when fresh in a 

 stronger degree. The bitterness is not so quickly communicated to the 

 taste, on chewing the bark, but is much more durable, especially about 

 the upper part of the fauces. Id.
