376 MEDICAL BOTANY. 



shaggy hairs on the under side, especially the veins and petioles. Panicles terminal, 

 rather long, leafy towards the base, with very villous pedicels. Calyx tomentose, with a 

 short, half-cleft limb. Corolla ? Fruit about half an inch long, oval, rather strongly-ribbed, 

 tomentose. 



Pavon, MS. ; Lindley, Flor. Med. 422 ; C. humboldliana, Lambert, 

 Bins. 7. 



Inhabits St. Jaen de Loxa. Nothing is known respecting its bark. 



15. C. oblongIfolia, Lambert. — Young shoots quadrangular, densely tomentose. Leaves 

 large, ovate-oblong or rather cordate, obtuse, scabrous, with down on the upper surface, 

 very densely and softly tomentose beneath, and having strong and prominent veins. Pe- 

 tioles tomentose, long. Panicle rather small, thyrsoid, terminal, tomentose, leafless, 

 shorter than the upper leaves. Calyx coarsely tomentose; the limb with five sharp teeth. 

 Corolla coarsely tomentose externally; the tube about thrice as long as that of the calyx; 

 the limb smooth inside, except at the edges, which are tomentose. 



Lambert, Illus. 12 ; Lindley, Flor. Med. 422; not of Mutis. 



Is a native of St. Jaen de Loxa. Nothing is known respecting its bark. 



3. Limb of the corolla smooth, or only downy at the edge. 



16. C. acutifolia, Ruiz and Pavon. — Shoots quadrangular, when quite young covered 

 with a fine soft down. Leaves ovate-lanceolate, acuminate, acute or obtuse at base, cori- 

 aceous, very even, somewhat undulate ; the midrib and veins of the lower surface covered 

 with long fine hairs, especially at the axils, which are not pitted ; the uppermost leaves 

 much narrower than the lower. Inflorescence leafless, tomentose. Calyx-tube very to- 

 mentose ; limb pubescent, deeply divided into long, narrow-channelled, obtuse teeth. Co- 

 rolla almost smooth, much longer than the calyx ; the segments of the limb smooth in- 

 side, except at the edge, which is covered with a short close down. 



Ruiz and Pavon, Flor. Feruv., in. 1, t. 225 ; Lindley, Flor. Med. 423. 

 Mountains of the Andes. Bark worthless. It is the Cascarilla de hoja 

 aguda, Ruiz and Pavon. 



17. C. magnifolia, Ruiz and Pavon. — Young branches quite smooth, scarcely angular. 

 Leaves oblong, sometimes narrowed towards the base, obtuse, often a foot long, coriace- 

 ous, strongly-ribbed, shining on both sides, perfectly free from hairiness, except when 

 very young, unless on the principal veins and at their axils. Flowers in a large termi- 

 nal, leafless thyrsus, with erect branches, merely downy, not woolly. Calyxrtube clothed 

 with a very short, dense tomentum ; limb pubescent, smooth at the edges, with oval, 

 obtuse, imbricating teeth. Corolla externally tomentose, with a tube hardly four times 

 as long as that of the calyx ; limb quite smooth inside, except "just at the edges, which 

 are tomentose. Fruit smooth, narrower at the base than at the apex, slightly ribbed. 



Ruiz and Pavon, Flor. Peruv., ii. 5 3, t. 196; Lindley, Flor. Med. 423 ; 

 C. caduciflora, Lambert, Illus. 11, not of Bonpland ; C. oblongifolia, Mutis, 

 according to Ruiz and Pavon, not of Lambert. 



Found in abundance on the mountains of Panatahuas, &c, in low land 

 near torrents, in situations fully exposed to the sun, but badly ventilated. 

 There is some discrepancy of opinion with regard to this species. Dr. 

 Lindley says, that in Dr. Thomson's Herbarium there is a branch of a 

 plant resembling this, but also approaching to C. pubescens. This is what 

 Mr. Lambert described as the C. inagnifolia of Ruiz and Pavon ; whilst 

 what he calls C. caduciflora is the true C. magnifolia of the authors of the 

 Flora Peruviana, but very different from M. Bonpland's plant of the former 

 name. Ruiz calls this species Cascarilla amarilla (Quinol. 71), and else- 

 where speaks of it as Case, de jlor de Azahar, and says it is not met with 

 in commerce, except in the form of an extract, which is of good quality. 

 Ruiz and Pavon state that it is C. oblongifolia, Mutis, but it is wholly dif-
