sent toward the South profiles of a thousand 

 feet in height. These springs arise for the mos t 

 part from a few narrow crevices. The humidity, 

 which they spread around, favors the growth of 

 the great trees ; and the natives, who love soli- 

 tary places, form their conucos along the sides 

 of these crevices. Plantains and papaw trees 

 surround tufts of arborescent fern. The mix- 

 ture of wild and cultivated plants gives the 

 place a peculiar charm. Springs are distin- 

 guished from afar, on the naked flanks of the 

 mountains, by the tufted masses of vegetation*, 



* Among the interesting plants of the valley of Caripe, 

 we found for the first time a calidium, the trunk of which 

 is twenty feet high (c. arboreum) ; the mikania mierantha, 

 which may probably possess some of the alexipharmic pro- 

 perties of the famous guaco of the Choco j the bauhinia ob- 

 tusifolia, a very large tree, called guarapa by the Indians ; 

 the weinmaunia glabra ; a psychotria-tree, the capsules of 

 which, when rubbed between the fingers, give a very agree- 

 able orange smell; the dorstenia houstoni (raiz de resfriadoj; 

 the martinia craniolaria, the white flowers of which are six 

 or seven inches long : a scrofularia, that has the aspect of 

 the verbaseum miconi, and the leaves of which, all radical 

 and hairy, are marked with silvery glands. The nacibaea 

 or manettia of Caripe (manettia cuspidata), of which I made 

 a drawing on the spot, is very different from the m. reclinata 

 4)f Mutis. This last, which serves as a type to the genus, 

 .Linnaeus places in Mexico, though it belongs to New Gre- 

 nada. Mr. Mutis has never been in Mexico ; and he re- 

 quested us, to acquaint those who pursue the study of botany, 

 that all the plants he sent to Upsal, and which are described
