found in Cayenne. (Vol. v. 767.) We are yet ignorant to 

 what genus the Cuspa, or quinquina of Cumana belongs, but 

 Hs properties being eminently febrifuge, it may become an 

 important object of trade. (Vol. iii. p. 27.) Five species of 

 real quinquina (Cinchona, corollis hirsutis), so common in 

 New Grenada, have been discovered in the western part of 

 Venezuela. The febrifuge-bark of the quinquina (buenas 

 quinas, or cascarillas) is gathered on both the declivities of 

 the Sierra Nevada of Merida, on the road from Varinas-vie- 

 jas to Paramo de Mucuchies, called the road of Los Calle- 

 jones, a little above the ravine of Lavellaca ; and also be- 

 tween Viscucuy and the town of Merida *. These are all 

 the real quinquinas (Cichonce) that have hitherto been found 

 principally on the coast of Spanish America. No species of 

 Cinchona is yet known, not even of the kindred genus, Exos- 

 tema, either in the mountains of theSillade Caraccas, where 

 the Befaria, Aralia, Thibaudia, and other alpine shrubs of 

 the Cordilleras of New Grenada vegetate, nor in the moun- 

 tains of Tumiriquiri and Caripe, and French Guyana f. This 

 total absence of the Cinchona and Exostema on the table- 

 land of Mexico, and in the oriental regions of South America, 

 north of the equator, (if it be as absolute as it has hitherto 

 appeared,) is the more surprising as the West Indies are not 

 destitute of quinquina with smooth corolla and projecting 

 stamina. In the southern hemisphere, the temperate parts of 

 Brazil also, have yet only furnished the botanic traveller 

 with one species of real Cinchona, a kind separated in a

 of Willdenow, with a calice of the length of the corolla, 

 and vegetating in the hot regions of Grand Para, is per-
