B About Cuchero, the Cinchona rosea of 
Ruiz and Pavon occurs not unfrequently ; 
it is a highly beautiful tree, which in its 
size and mode of ramification may be justly 
compared with the white Beech of Europe, 
adorned in July with innumerable pale 
violet flowers, and in its growth, circum- 
Cinchonas, the trunk seldom exceeding 
from six to twelve inches in diameter. Its 
name of Palo de San Juan refers to the 
flowering season. Of the bark no use is 
made, for no one supposes it to belong to 
the Cinchonas; but there can be little 
doubt that their peculiar properties would 
be found, on examination, to exist in the 
thin and smooth bark of its riper branches. 
In the adulteration of the superior sorts 
of bark (a very common practice), the bark 
of the Azahar, described above, was chiefly 
employed. It however bore too much re- 
 Semblance to Oak-bark, and was so heavy 
and easily distinguishable by its very sharp 
and disagreeably bitter flavour from the 
fine aromatic taste of the genuine kind, 
that the imposition could not prevail to a 
very great extent. The bark of the Lu- 
. Cumo, perhaps a species of Achras or Cer- 
E vantesia, was similarly employed, but it 
. hadtoo foreign an appearance to be mixed 
in any great quantity, and the same may

. White flowers. By many, however, it has

by preparing a large quantity of the ex- 
tract; but his article met with a bad sale 
in England, where the Quinine was already 
extensively imported. Samples of it, how- 
ever, that had been preserved in the damp 
primitive forests, by enclosure in leaden 
boxes, were examined by competent judges 
in Germany, and pronounced to be of ex- 
cellent quality, and possessing an aroma 
very superior to the extract made in Eu- 
rope from the dried bark. 
The Cryptogamia on the barks of Cu- 
chero, besides many undescribed species, 
are, 1. On Cascarilla provinciana—Aste- 
risca cinchonarum, Graphis subcurva, G. 
Cascarille, and G. byssiseda ; Lecanora 
pallido-flava, Verrucaria parasema, and 
of the larger lichens only the Usnea cin- 
chonarum.—2. On Cascarilla Negrilla— 
Lecanora punicea, Lecidea grisea, Ver- 
rucaria exasperata, Graphis sub-bifida, 
Variolaria microcephala, and Parmelia 
melanoleuca.
