smell, which is considerably aromatic, becomes perceptible on 
pulverization or decoction ; its bitterness is successively deve- 
loped by a prolonged mastication, but it is always very inferior to 
that of the Calisaya; it is also styptic, but without acerbity. 
This Bark is rarely found without mixture: on its external 
surface are to be observed some slight transversal and almost 
parallel fissures.*

‘Tus is the name which this Bark bears in Peru; it is more 
‘common. ‘than the former, and is found in greater quantity 
among the barks used in the royal pharmacy.t 
* It is astonishing that the botanic characters of this species have not yet been published, 
and that M. Ruiz has not given a description of its bark in his Quinologia. M. Pavon having 
had the politeness to shew us a drawing of this tree, carefully made under the inspection of 
M. Tafalla, and which will be published in the fourth volume of the Flora Peruviana; we 
have the pleasure of indicating the most prominent specific characters which we have remarked 
on this plate, Cascarilla amarilla del rey, or Royal yellow Quinguina, is the name which it 
bears in the drawing; folits lanceolatis glandulosis obscure virescentibus, petiolo nervoque cen- 
trali sunguinets, Jflore rubro. M. Pavonhas informed us that this bark detaches easily from 
the w od, and that the most experienced barkers distinguish it by this separative character. 
Some days. after the extraction it is nut to be distinguished from that of No.2; when it is fresh 
‘gathered the colour of the internal Surface is of a greenish white, which soon changes into a 
faint yellow, augmenting in intensity notil the desiccation is complete, ‘The tree or shrub 
which produces it is of the same heizht and exhibits the same structure as that. of the meal 3 yet 
M. Tafalla designates them in his drawings as forming two different species, 
_t M. Pavon having had the politeness to shew us the drawing of this shrub, we nines 
cognised in it the following characteristics; C. foliis lanceelatis glandulosis, petiolo nervoque 
centrali sunguineis, flore rubescente. The two drawings appeared to us so similar that we 
found only a slight difference inthe colour of the flower, and were unable to discern on what 
veharacter their. specific difference could be established. 
__ At the moment of extraction this bark. assumes internally the colour of saffron, though rather
