CINCHONA. 



scribe it. It appears to differ from C. magnifolia in its corolla being quite 

 smooth, with a tube only twice the length of the limb of the calyx, 

 and in the stamens growing from near the base of the tube of the 

 corolla, not in the middle of the tube. These characters are abundantly 

 sufficient to separate it from C. magnifolia, to which however it is very 

 closely allied. If we are to trust the figure in the PlanUe (squinoctiales 

 the fruit is not obovate as in the species just named, which constitutes 

 another mark of distinction. It is stated in the PI. eequinoct. that this 

 is called Cascarilla bora, near the town of Jaen de Bracamoros, and that 

 no use is made of its bark, " although that of the trunk contains a great 

 quantity of resin." 



847. C. stenocarpa Lambert Ulustr. 13. Jaen, in the moun- 

 tains of Loxa, Pavon. 



Branches rather quadrangular, when young very slightly pubescent. 

 Leaves elliptical, acute, tapering to the base where they end in a long 

 smooth stalk, rather shining, not coriaceous, but about the texture of 

 the leaf of an apple tree, smooth on the upper side, paler on the under 

 side, and slightly hairy, especially upon the veins and at their axils ; the 

 principal veins prominent. Panicle terminal, thyrsoid, loose, leafless, 

 pubescent. Calyx-tube long, narrow, tomentose ; limb 5-parted, pube- 

 scent, rather membranous, with the segments acute. Corolla pubescent ; 

 tube slender, funnel-shaped, rather more than 3 times the length of that 

 of the calyx; limb slightly spreading, with narrow acute segments, 

 which are smooth, except near the margin. Fruit about 2 inches long, 

 narrow, smooth, the same width at each end. There are 2 specimens 

 in Mr. Lambert's herbarium, and 3 in Dr. Thomson's. They are so very 

 much like the figure and description of C. caduciftora that I see little to 

 distinguish them except the greater length of the tube of the corolla, 

 and I should be inclined to think them the same if M. Bonpland had 

 not stated that he found no difference between the leaves of that species 

 andC.

 mag. 1. c. p. 118. Loxa, Pavon. Santa Fe Humboldt; a sup- 

 posed variety is said to grow about Santa Martha. 



Young branches acutely quadrangular, very tomentose. Leaves cori- 

 aceous, obovate, obtuse, revolute at the edge, sometimes slightly cordate, 

 when young tomentose on both sides ; when full grown smooth and 

 shining on the upper side, except the midrib and principal veins which 

 continue tomentose, on the under side thinly covered with down except 

 along the midrib and principal veins, which are very tomentose. Cyme 

 terminal, consisting of about 9 pedicellate flowers in 3 parcels : ex- 

 tremely tomentose, with a pair of small rhomboidal obtuse leaves at 

 the base. Branches of the inflorescence and pedicels short and thick. 

 Calyx obconical, very tomentose inside as well as outside, with a 

 spreading, shallow, 5-toothed limb. Corolla very tomentose, about 

 1J inch long, with the tube nearly i of an inch in diameter; the limb 

 spreading, smooth inside, tomentose at the edges. I have only seen 

 3 bad specimens of this remarkable plant, which appears from a single 

 loose fruit in Mr. Lambert's herbarium to approach the genus Cosmi- 

 buena. This fruit does not however at all agree with that figured by 

 Vahl, which is very like the capsule of C. magnifolia. This C. macrocarpa
