    298. (23) Buena HEXANDRA, Poll. a. Portion of quilled bark, with periderm. Note.—This is the bark described under the name of Nova colorada de Brasil by Guibourt. See Hist, des Drog., t. iii., p. 183. It has a dark inner surface, and the periderm is thick and deeply furrowed ; the taste is nauseous and astringent. (24) Cascarilla Carua, Wedd. (False Bed Bark.) a. Thick curved pieces. Note.—This bark is known in Peru and Bolivia under the name of Cargua-cargua grande. It is similar in appearance to the bark of Buena Bogotensis, but has a paler and more fibrous inner surface. Neither that bark nor this one contains any alkaloid. (25) Cascarilla globifera, Pav. a. One quilled piece. Note.—This bark somewhat resembles that of C. micrantha externally, but its inner surface is very fibrous. It is labelled Unas de gato. See P. J. [1], vol. xii., p. 176, no. 32 ; also p. 341. (26) Condaminea tinctoria, D. C. (Paraguatan Bark.) a. Large quilled pieces. Note.—This bark is remarkable for the peculiar deep pink colour of its substance. The periderm is thin and easily removed. In Peru it is known as socchi. See Hist, des Drog. vol. hi., p. 184 ; P. J. [1], vol. xii., p. 341. (27) Croton species. a. Thin, wide flat pieces. Note.—This bark is covered with large woody blunt prickles, which, together with its peculiar taste, appear to ally it rather to the bark of a Zanthoxylum than a Croton. (28) Gomphosia chlorantha, Wedd. a. Quills. Note.—This bark much resembles Calisaya quill, and was at one time sold for it. It may be distinguished by the periderm being readily separa- ted into layers, which are of a purplish tinge. It contains no alkaloid. A mounted microscopical slide of a section of the bark accompanies this specimen. See P. J. [1], vol. xiv., p. 318. It comes from Carabaya. (29) Laplacea qdinoderma. Wedd. a. Flat or slightly curved pieces. See P. J. Note. This bark at one time came mixed with flat Calisaya. It differs very much from it in appearance, being of a blackish red colour, and having very persistent tough fibres. Its native name is Viehullo vei Chulquisa. It is labelled scarce and interesting under the micro- scope. (30) Stenostomum acutatum, D. G. (Pitoya Bark.) a. Long quills. Note.—This bark was known in England as Pitoya bark, and from it a principle named pitoyine was obtained, a specimen of which is attached to this bark. By Guibourt it is described as Quinquina bicolore. The quills are very long, quite smooth, and brown externally, and black on the inner surface. It cannot possibly be confounded with any cinchona bark. See Hist, des Drog., t. hi., p. 190.
