CINCHONA.the knots. Leaves obovate-lanceolate, acute at each end, not coriaceous,nor membranous, quite smooth on both sides, not scrobiculate underneath.Flowers unknown. Fruit between 2 and 3 inches long, slender,clavate, tipped by the remains of the calyx, arranged in cymes whosebranches are divaricating and rather dichotomous. It is very uncertainwhether this is really a Cinchona. According to R. and P. the barkhas the reputation in Chichoplaya of being one of the Quinas finas,or best for medicinal purposes.

C. lucumaefolia is quoted as avariety, but that plant does not at all agree with the specificcharacter given by M. De Candolle. Another variety is said tobe the C. Uritusinga, but that should be C. Condaminea.851 a. C. crassifolia Pavon in iv.DC.prodr. 354. This doesnot well correspond with any species I have seen, unless it bewith some branches of a plant confounded with C. macrophyllain Mr. Lambert's herbarium.852. C. Pelalba Pav. in DC. prodr. iv. 355 is possibly C. rotundifolia,but the character ascribed to its inflorescence is at variancewith that species.853. C. Muzonensis Goudot. DC. prodr.iv. 355. ; I haveseen nothing like this.The result of the preceding inquiry, so far as it affects the barksordinarily used in this country, is shown in the following table ofofficinal names referred to their species:(a)Pale Barks.Crown or Loxa Bark - C.
