$King-WOOD, Maracaybo-wood and Mustaiba-wood, all im- iS7i. ported from Brazil, and NiCARAGUA-wooD from Central America, are of unknown botanical origin. The Eose-woods of Brazil.—There is still some doubt as to the trees which yield the different varieties of this timber. Ipecacuanha.—What is the plant which furnishes the large Ipecacuanha root of New Granada? Pareira Brava.—The plant affording the inert woody stems which constitute the Pareira B^^ava of commerce, and which are exported to Europe from Eio de Janeiro, has not been ascer- tained, neither is the locality in which it grows accurately known. The subject is deserving of investigation. Cinchona Bark.—In addition to the bark of CincJiona Tucu- jensis, shipped at Puerto Cabello in Venezuela, there are others less known botanically which are brought from the same port. Some of these barks appear to be derived from varieties of Cin- chona cordifolia, while others seem to belong to what is called Quinquina rose d'Ocaiia. It would be interesting to have authentic specimens of the flowering and fruit-bearing branches of the trees, together with sections ef the branches and trunk (the bark being in situ), for comparison with the species described . by Karsten. . The so-called False Cinchonas may be distinguished, according to ]3r. Weddell, by their capsules, which are generally large, and liaving valves which separate from the apex towards the base. The flowers are relatively la.rge, and devoid of perfume. It would be of some interest to have authentic specimens of the barks of those trees belonging to the genus Buena {Gascarilla or Ladenhergia) in order to ascertain whether they contain alkaloids or not. The barks ought to be accompanied by flowering specimens. Some pounds of each bark would be required for chemical examination. Para Ehatany.—This root, imported from Para in Brazil, is described in Pharmaceutical Journal, i. (1870) 84. The plant yielding it should be ascertained, for which purpose good speci- mens, including entire roots, are requisite.$
