three species, we shall describe them, separately, under the 
names which they bear in commerce ; that is to say, Calisaya 
arrollada, Calisaya de Plancha, and Culisaya de Santa Fe. 
I. Calisaya arrollada (or rolled Calisaya) known also by the 
, name of Calisaya de Quito. el. 
Its epidermis a line and a half thick, rough, almost taste- 
less, dark tawny colour, with some whitish spots and deep cir- 
cular clefts, through which are often perceived traces on the liber 
or inward rind; the large barks are half rolled, and the small 
ones entirely. Destitute for the most part of epidermis, it pre- 
sents a smooth surface of the colour of ochre inclining to yellow; 
its internal colour inclines somewhat more to orangé; the rolled 
barks are in general more compact than the others; the frac- 
ture is almost equal, on both sides, with some very small fibres; 
the epidermis is quite resinous; its odour is very faint; it is less 
aromatic and styptic than the Quinquina of Loxa; but much 
more bitter. This bark appears in ‘most respects to resemble 
that of the C. lanceolata. == : 
Il. Calisaya de Plancha. 
A very thick bark, known also by the name of Cortezon* 
pees 
(thick bark) and of Cascarilla Callisalla by the inhabitants of 
La Paz. It is generally met with in large flat pieces com- - 
monly two.lines: in thickness and one or two inches long, some 
slightly curved, almost always destitute of epidermis,+ and thus 
* M. Ruiz has described only the Cortezon in his Quinologia ; but he has given us chives 
different samples, and the barks to which they belong are sufficiently common in commerce. 
+ The Cascarilleros would not find room for their barks if they were stripped of their epi- 
dermis, To extract the barks in such a state as they are-demanded in commerce, it is neces-
