CINCHONACEJE. 



is not however a real Cosmibuena as is sufficiently proved by its valvate 

 corolla and permanent calyx. By some mistake it is said in the 

 Plantae aequinoctiales (i. 67.) to be the same as Cosmibuena obtusifolla, a 

 totally different plant. R. and P. in the Suppl. quinol. say that this is 

 the Quina blanca or Cinchona ovalifolia of Mutis. 



Vahl asserts, in the place above referred to, that the specimen pre- 

 served in the Linnean collection is this species, and consequently that 

 C. macrocarpa is what was first discovered by Mutis in Santa Fe. How 

 entirely this statement is devoid of foundation will appear from the 

 following memorandum made by me upon examining the Linnean 

 collections a few weeks since. 



In the herbarium of the elder Linnaeus there is a specimen marked 

 C. ojficinalis, in the handwriting of that Botanist, which is not a Cin- 

 chona at all, according to the modern limitation of that genus ; it does 

 not appear whence. In the same herbarium is a specimen of a leaf of 

 some plant not belonging to the genus Cinchona, and glued to the same 

 paper 2 loose fruits resembling that of C. stenocarpa, the whole received 

 from Mutis, and marked, but not by Linnaeus, Cinchona peruviana ; 

 attached to them but on a separate sheet of paper are loose flowers of 

 2 species of Cinchona mixed together, part of which certainly belongs 

 to C. pubescens. Finally there exists along with these evidences a 

 barbarous figure, transmitted to Linnaeus by Mutis, of some Cinchona, 

 which cannot have been intended for C. macrocarpa, but which is more 

 like C. pubescens , and of no authority for anything ; the only precise fact 

 exhibited by it being that the flowers are dark purple. In Smith's 

 herbarium among the younger Linnaeus's materials is a specimen from 

 Mutis marked " Arbre de Quinquina qu'on vient de decouvrir au roy- 

 aume de Santa Fee " which is C. pubescens. Nothing like C. macro- 

 carpa is to be found.

Young branches tomentose. Leaves stalked, oblong,"subcordate or 

 obtuse at the base, obtuse or rounded at the apex, 8 or 9 inches long, 

 and 6 or 7 broad, rather coriaceous, smooth above, tomentose beneath. 

 Cyme terminal, very compact, trifid, tomentose, shorter than the leaves 

 next below it. Calyx-tube long, narrow, tomentose ; limb cyathiform, 

 spreading away from the corolla, pubescent, with 5 shallow blunt teeth. 

 Corolla full 2 inches long, tomentose externally ; tube rather curved ; 

 limb valvate, tomentose, not stupose. Anthers inserted in the throat. 

 Fruit cylindrical, between 5 and 6 inches long, smooth, not ribbed, 

 tipped by the hardened remains of the permanent calyx cup. On the 

 ticket of this plant in Mr. Lambert's herbarium are the following words : 

 " Cinchona cava. Sp. nova inedita vulgo Canela, de Loxa Quito Peru. 

 Es preciosa esta planta." Nothing more is known of it.
