CINCHONA. 



the knots. Leaves obovate-lanceolate, acute at each end, not coriaceous, 

 nor membranous, quite smooth on both sides, not scrobiculate under- 

 neath. Flowers unknown. Fruit between 2 and 3 inches long, slender, 

 clavate, tipped by the remains of the calyx, arranged in cymes whose 

 branches are divaricating and rather dichotomous. It is very uncertain 

 whether this is really a Cinchona. According to R. and P. the bark 

 has the reputation in Chichoplaya of being one of the Quinas finas, 

 or best for medicinal purposes. It does not appear to have any native 



851. C. macrocalyx DC.prodr. iv. 353. I am unable to refer 

 this to any species I have seen. C. lucumaefolia is quoted as a 

 variety, but that plant does not at all agree with the specific 

 character given by M. De Candolle. Another variety is said to 

 be the C. Uritusinga, but that should be C. Condaminea. 



851 a. C. crassifolia Pavon in DC.prodr. iv. 354. This does 

 not well correspond with any species I have seen, unless it be 

 with some branches of a plant confounded with C. macrophylla 

 in Mr. Lambert's herbarium. 



852. C. Pelalba Pav. in DC. prodr. iv. 355 is possibly C. rotun- 

 difolia, but the character ascribed to its inflorescence is at va- 

 riance with that species. 



853. C. Muzonensis Goudot. DC. prodr. iv. 355. ; I have 

 seen nothing like this.
