It is of excellent quality, yielding 7-8 per cent, of alkaloids. See P. J. [2], vol. viii., p. 593, No. 4, 5. Var. 8. Bonplandiana, /. lutea, How. (H. 0. Grown hark, ^partly.) See Howard, Quinol. E. I. Plantat., p. 89 and pL xi. a. Quills. P. J. [1], vol. viii., p. 671, No. 1. Note.—This appears to be the same as the amarilla del Eey of E. et P. in the British Museum. It is the bark described under the heading of d in Per. Mat. Med., 3rd ed., vol. ii., pt. ii., p. 1639 ; and the C. lutea and amarilla del Eey of Pavon. This bark is of a dark grey colour, with very numerous transverse cracks, interspersed among which are numer- ous small raised warts of the same coloui- as the bark.

Med., vol. ii., pt. ii., p. 1609, note 3. It is the true Loxa bark of Humboldt, and the cascarUla fina de Loxa of Euiz and Pavon.

Analysed by Howard, it yielded— Quinidine and uncrystallizable quinine ... 0-40 Cinchonine 0-03 0-43 East Indian bark obtained from this species yielded only 0-629 per cent, of alkaloids. See P. J. [2], vol. viii., p. 593. The specimen in this collection is remarkable for the thick edges of the numerous ramifying fissures, which form a sort of raised network on the bark. It closely resembles in size and colour the East Indian Uritusinga bark. (13) Cinchona ovata, Wedd. Var. a. VULGARIS, Planch. a. Flat pieces. Note.—This specimen much resembles Calisaya ia appearance, but is not so bitter, and has the remains of a silvery periderm.
