Flora Medica

Ruiz quinol. 74. Close ill ventilated grovesin the hotterparts of the foot of the Andes near Pozuzo and Panao 10 leaguesfrom Huanuco. R. and P.Branches 4-cornered, thick, smooth, except towards the ends wherethey are hairy -rather than tomentose. Leaves large, thin, ovate-oblong,when young velvety on the underside with a short thick felt, whichfalls off as the leaves grow older, smooth on the upper side; when fullgrown obtuse, or rather acute, at the base, with smooth petioles andshaggy axils to the under veins the ; uppermost leaves almost cordate.Peduncles thick, quadrangular, tomentose, branched in the axils of theupper leaves, and leafyat their own base, forming a coarse compoundpanicle. Flowers sessile, or nearly so, in thick clusters. Calyx verytomentose, except the limb, which is smooth, thick, campanulate,5-toothed, and apparently deep purple. Corolla purple according tothe Flora Peruviana, tomentose, with a spreading, white, shaggy limb.Of this Mr. Lambert's herbarium contains 3 specimens just passedflowering ; along with which are glued down some oblong, ratherstrongly ribbed fruits, which are very obtuse at each end. As they donot correspond well with the figure and description in the Flora Peruviana,perhaps they do not belong to the specimens. According to amemorandum in M. Bonpland's handwriting in Mr. Lambert's herbarium,this was considered by the former botanist as a variety ofC. cordifolia of Mutis. It is however perfectly distinct both from thatspecies, and the C. pubesccns of Vahl. Ruiz states that this is calledin Panao Cascarillo con corteza de color de Patade Gallareta, The barkis not employed in commerce, but it has been used in preparing theextract of Cinchona by the factors of Panao. It is added by Pavon inthe Quinol. suppl. p. 18. that it is identical with C. cordifolia of Mutis,the Quina Amarilla of Santa Fe ; but Ruiz in his MSS. does not confirmthis ;on the contrary he is unable to say what species produces theQuina Amarilla or Q. Baya de Santa Fe, and he speaks of this species,the Pata de Gallareta as quite a distinct kind, of the lowest quality.According to Bergen this is the origin of the Jaen, corrupted into Tenbark or Ash bark of commerce ;but this is very doubtful jthere is noproof of its growing about Jaen.837. C. rotundifolia Ruiz and Pavon MSS. in herb. Lambert.Lambert illustr. cinch, p. 5. Loxa in Quito Pavon.Branches clothed with a short thick fur towards the extremities.Leaves roundish-oblong, obtuse, but not cordate, at the base, hardlyacute, thin, quite naked on the upper side, except along the midrib, onthe under side soft with down, not pitted, with the short petioles andveins covered with a close thick fur. Peduncles corymbose, tomentose,in the axils of the upper leaves, forming a close leafy thyrse. Flowerssessile, in very dense clusters. Calyx tomentose, with a short 5-toothedlimb. Corolla tomentose, rather funnel-shaped, with the tube about 4times as long as the tube of the calyx the ; segments of the limb shacgyinside. I have only seen 2 specimens in Mr. Lambert's herbarium.The species is perfectly distinct from all others ;but I know not if the2 separate, narrow, cinnamon-coloured unribbed capsules in that collectionreally belong to the specimens. It is most nearly allied toC. ovata, from which it differs in its thinner, and oblong not ovate leaves,in its tomentose petioles, smaller panicles, hoary calyx cup, and, if thefruit may be trusted, in that respect also.418
