BOTANICAL ORIGIN. 13 
strict separation observable, but rather gives thereby to his views 
the particular expression that he refers all the Cinchonas to 5 stems 
(souches, stirpes). To these fundamental forms, from which all 
others radiate, Weddell assigns the name of the Cinchona which, 
for the respective stem, is the most striking or the best known, 
namely: 1. Stirps of Cinchona officinalis, 2. Stirps Cinchone 
rugos@. 3. Stirps Cinchone muicranthe. 4. Stirps Cinchone 
Calisaye. 5. Stirps Cinchone ovate. The last forms accepted by 
Weddell approach already very closely to Cascarillos bobos, or to 
the spurious cinchonas, namely, on account of the slender cap- 
sules, which dehisce from the apex. 
Kuntze’ desires to have all the cinchona trees referred to four 
species, and declares the numerous species represented by other 
botanists, with the exception of Howard's Cinchona Pahudiana, 
as hybrids of the four species, which have been described by 
him in sharply discriminating diagnoses and in light outlines. 
From Kuntze’s disquisition the following review is obtained :— 
A. Cinchonas with coarse, not very large leaves; the capsules so 
contracted longitudinally in the centre that both halves of the fruit 
appear plainly evident. Each of the latter is provided with from 
4 to 6 ribs, but both are held together by the widely expanded 
funnel-shaped calyx of the fruit. 
(1) CincHona WeEDDELLIANA is provided with leaf-pits, sevodiculi, 
and is distinguished by the only slightly lengthened, nearly spherical 
capsule, which is crowned by a very small fruit calyx. 
(2) CincHona Panuprana, in distinction from the above, is pubes- 
cent, the corolla tube is pentagonal, and the fruit calyx almost as 
wide as the fruit itself. 
B. Cinchonas with less coarse or thin, often very large leaves. 
The capsule is somewhat dilated, almost cylindrically beaked, 
scarcely contracted longitudinally, without ribs, and terminating 
without contraction in the small unexpanded calyx. 
(3) Cincuona Howarprana is remarkable for the not pure 
green color and the significant size of the leaves, which, even in the 
inflorescence, are still quite prominent, and are always devoid of 
pits; and also for the remarkable width of the pale wing of the 
seeds. | 
(4) CrvcHona Pavontana deviates therefrom in possessing, at 
least on the flowing branches, leaves of a beautiful green color, 
which are provided with leaf-pits; but, on the contrary, only yellow- 
_ ish-white, not bright flowers. : ee
