pear white, although they are tinged of a red colour, the calyx being purplish. It flowers in May, June and July. 
Its habitation is in high, cool and wooded mountainous districts of the Andes near San Antonio de Playa grande, 
whence Tafalla in 1797, procured it and gave specimens to Ruiz and Pavon It grows in Peru near Chicoplaya and 
Monzon, and in the vicinity of St. Jaen Bracamorros, where it was found by Humboldt and Bonpland. 
Dr. Lindley regards this plant as unquestionably the same as C. scrobiculata. H. and B. and R. and P. unite in 
stating that from the tree is obtained the Cascardlla fina. ‘The former say it is the most common and most esteemed 
kind of all collected in St. Jaen. 
Upon Poppig’s authority, who is the latest trustworthy writer, it appears that the C. micrantha is the source of the 
bark which, in the vicinity of Cuchero, is called Cascarilla provinciana. M. Reichel compared his specimens of it 
with those of Bergen and found that they were the same as the Huanuco bark of commerce. Hence, as admitted by 
Lindley and Pereira, it affords the Si/ver or Gray bark of English commerce. 
The Ash Cinchona of Bergen, Cinchona Jaen, is an inferior pale bark, supposed to be derived from C. ovata, but 
Lindley states that there is no evidence that this species grows about Jaen. It is probable that the bark in question is 
an inferior kind of that from C. micrantha, (of which Poppig states there are three kinds, the finer peeled from the 
branches, and answering to Cascarilla fina,) or it may be from some other species in the neighbourhood, which affords 
inferior barks, as stated by H. and B. 
Huanuco bark always occurs in the form of quills; they are larger and coarser than those of Crown bark, approach- 
ing to yellow, but smoother on their external surface. The quills are three to fifteen inches in length; in diameter two 
lines to one or two inches; in thickness from one-third to five lines. The edge of the quill is oblique, not found on 
other bark. The epidermis is transversely cracked, not in the form of rings as in Loxa bark, and the edges of the 
cracks are flat. On the thicker quills are to be observed longitudinal furrows, and the cracks are frequently wanting. 
The colour of the epidermis is whitish, in the smaller quill whitish-gray ; in the larger, cretaceous. This depends 
upon crustaceous lichens, and from it arise the terms silver and gray. The structure of the inner surface is smooth 
in the small quill, fibrous in the larger ones; the colour is reddish or rusty brown. The fracture is even and — 
the odour clayish or sweet, which, according to Bergen, 1s peculiar to it. ‘Taste astringent, aromatic, and bitter; pow-
