possibly be confounded with any other. It is said by the authors of the 

 Flora Peruviana to be commonly called Cascarillo or Quino bobo amarillo 

 on account of the colour of the bark inside, which in flavour is very 

 like that of Quina de Calisaya. Ruiz says it is mixed in commerce with 

 that of C. hirsutaand C. nitida and he suspects it to be the real source 

 of Calisaya bark. In his manuscript history he says the bark of this is 

 also called Quina Anteada, Cascarilla Amarilla, and Case, boba de Muiia, 

 and that it is one of the finest sorts. I presume this must be the source 

 of the Yellow bark of the English druggists; it is however uncertain 

 whether the Calisaya bark from La Paz, at the extreme southern limit 

 of the Cinchona districts, inhabiting a different climate, has the same 

 origin. M. Guibourt assures us (ii. 80.) that specimens purporting to 

 be those of trees yielding Calisaya, and brought from La Paz by 

 M. Auguste Delondre, a French traveller in Upper Peru, belonged to 

 C. micrantha, Condaminea, and 3 other species. But in the interior of 

 one of the quills he found a leaf, which appeared to him to belong to 

 C. lanceolata, and this he conjectures to be really the species furnishing 

 the bark.

Branches smooth, apparently rather angular and furrowed. Leaves 

 rather thin, exactly oval, scarcely acute at the point, tapering off into 

 an unusually short petiole, except in the case of those leaves which 

 are next the panicle, which are rounded at the base so as to acquire 

 an ovate or even cordate form; not at all shining, smooth on the 

 upper side, finely and impalpably downy on the under, especially 

 when young, with the veins, especially their axils distinctly hairy, 

 but without a trace of pits; when old losing their down. Panicle 

 terminal, naked, thyrsoid, small, downy, now and then with small 

 leaves subtending the lower branches. Calyx tomentose, with a shal- 

 low, 5-toothed, downy limb, which does not alter its form after flower- 

 ing, except by enlarging a little and hardening. Corolla tomentose, 

 rather funnel-shaped, as small as in C. micrantha, with the tube 3 or 4 

 times the length of the tube of the calyx ; the limb shaggy in the inside. 

 Fruit oval, rather downy, very strongly ribbed when ripe. Of this 

 species 3 specimens in the Lambertian herbarium, and 2 in that of Dr. 

 Thomson, agreeing pretty well with the figure in the Plantae aequinocti- 

 ales, sufficiently show that it is a species quite distinct from C. micrantha, 

 from which its strongly ribbed fruit and the texture or form of the 

 leaves certainly distinguish it. One of the specimens in Mr. Lambert's 

 herbarium is named by Pavon " C. purpureae affinis, sp. nov. ined. in 

 regno Quitensi Loxa." It is stated in the Plantce eequinoctiales that the 

 bark of this species is not much esteemed ; but that nevertheless a con- 

 siderable quantity had been cut about the year 1782. It is reported in 

 the same work to be called Cascarilla peluda, or " velvet-leaved Quina ;" 

 but I doubt whether this is not a mistake, because the leaves are so 

 little downy that an ordinary observer would call them smooth except 

 when young. In the last collection of Cinchonas received from Ruiz 

 and Pavon's herbarium by Mr. Lambert, and from among which I have 

 been favoured with a specimen, this is named, evidently by mistake, 

 C. lanceolata.
