374 MEDICAL BOTANY. 



not confirm this, as he expressly states that he is unable to say what species 

 affords the Quina amarilla or Q. baya de Santa Fe. In his work he says 

 this is called Cascarilla con corteza de color de Pata de Gattereta. Pereira, 

 on the other hand, observes that Bergen found his China jaenox ash-coloured 

 bark to be identical with that of the C. ovata, contained in Ruiz's collection. 



9. C. rotundifolia, Ruiz and Pavon. — Branches covered with a short, thick fur near 

 their extremities. Leaves roundish-oblong, obtuse but not cordate at the base, scarcely 

 acutt, thin, quite naked on the upper side, except along the midrib, beneath soft with 

 down, not pitted. Petioles and veins covered with a close thick fur. Peduncles corym- 

 bose, tomentose, forming a close leafy thyrsus in the axils of the upper leaves. Calyx 

 tomentose, with a short, 5-toothed limb. Corolla tomentose, rather infundibuliform, with 

 the tube about four times the length of that of the calyx. Segments of the limb shaggy 

 within.

This species is found in Loxa. Nothing is known of the bark it affords. 



10. C. cordifolia, Mutis. — Branches quadrangular, smooth. Leaves roundish, obtuse 

 at both ends, especially at base, or roundish-oblong and tapering to the base, strongly- 

 veined, thin, smooth above, downy beneath, and hairy at the veins and axils when young, 

 becoming nearly smooth when old ; never pitted. Panicle contracted, thyrsoid, leafy at 

 base, or formed of corymbose peduncles, axillary to the upper leaves, with the ramifica- 

 tions tomentose. Calyx tomentose, with a large, smooth, campanulate, 5-toothed cup, the 

 lobes of which become quadrate and cuspidate ; the tube sub-globose when it first begins 

 to enlarge after the fall of the corolla, afterwards becoming longer. Corolla tomentose, 

 with a thick tube, whose diameter is equal to the length of the shaggy lobes.

Mountains of New Granada, at an elevation of from 5000 to 8000 feet. 

 According to Humboldt and Bonpland, this tree furnishes Quina jaune, but 

 there may be some error in this, as Dr. Lindley states that Bonpland con- 

 founded several species under this name. Ruiz and Pavon also say, that 

 their C. ovata is the C. cordifolia, Mutis, and affords the Quina amarilla of 

 Santa Fe ; but in his MS.., Ruiz speaks of the bark of C. ovata as totally 

 distinct from the Q. amarilla. Dr. Lindley supposes that the Quina baya 

 or the Q. amarilla may be the product of this species, and Pereira states that 

 the bark spoken of by Mutis, under this latter name, has been ascertained by 

 Bergen and Guibourt to be the Hard Carthagena bark. 



11. C. pubescens, Vahl. — Young branches, covered with a short, close down. Leaves 

 never pitted ; when young, rather thin, not shining, somewhat downy on both sides, most 

 so on the under and upon the petioles ; when older quite smooth, much firmer, and quite 

 shining ; those near and among the inflorescence roundish, somewhat broader than long, 

 tapering into a long stalk, or merely ovate ; those below the inflorescence ovate-oblong, or 

 nearly oval, and acute. Peduncles trichotomously-branched, corymbose, many-flowered, 

 tomentose in the axils of the upper leaves, forming a short and broad, spreading and leafy 

 thyrsus, the flowers in which are by no means compactly arranged ; the subdivisions 

 being at almost right angles with each other. Pedicels and calyx-tube covered with a 

 close fur ; the limb of the latter downy, with five shallow, ovate, acute teeth. Corolla 

 tube tomentose, much contracted at base, and nearly six times the length of that of the 

 calyx ; limb deep purple, shaggy inside. Fruit tomentose, narrow, oval, as thick at one 

 end as at the other ; about an inch long.
