latter on the spot, could scarcely remark any difference in the 
size of the leaves. | 
Surface rough, split transversely, and covered with mucors of a 
clear tawny colour with some blackish spots ; internal surface more 
or less orange-coloured, pretty well rolled, from half a line to 
a line in thickness, and from half an inch to an inch in cireum- 
ference; fracture fibrous, the two fragments being crowned with 
little longitudinal fibres; it 1s with some difficulty frangible, 
thoug gh the circumference i is spongy ; its smell is faint, and very 
perceplible on pulyerization or decoction; the bitterness suffi- 
ciently manifest and not agreeable; not styptic. 
Considerable resemblance exists between this bark and that 
of the species discovered by Tafalla at Chicoplaya, of which we 
have previously spoken. The only difference is, that the barks 
of the latter are cloven both transversely and longitudinally, pre- 
senting more imequality im size and thickness, and more irregu- 
jarity in the colour of their internal surface; in other respects 
they. 8 are the same. i

-M. Vahl has published the white Quinquina of Santa Fe under 
the specific name of macrocarpa,* according to the specimens ~ 
of it which he received from Professor Ortega of Madrid. The 
barks of the macrocarpu have a greyish epidermis, very fine and 
soft to the touch ; the internal’ surface yellowish, smooth, shining, 
and furrowed; the interior of the bark of a greyish yellow ; 
thickness from a quarter of a line to a line; they are rather 
Spongy internally and in flat pieces; they crack easily between 
the’ teeth, and readily dissolve in the mouth, which, perhaps, 
causes them to, be regarded as very saponaceous, slightly
