TIL. Casearilla claro-amarilla, or Quinquina of a clear yellow. 
This bark, of which the species is unknown, greatly resem- 
bles the orange-coloured Quinguina of Mutis. The epidermis 
is thin, covered with some whitish lichens, and easily sepa- 
ora ble from the rest of the bark; the colour yellow slightly 
partaking of red; it is ef a faint bitter and considerably styp- 
tic without being nauseous: in its other characters it resem- 
bles the Calisaya ; but is easily distinguished by a much weaker 
bitter, and by the fineness of its epidermis ; ; it is often found with 
the Huanuco. 
IV. Casearilla pagiza. 
This is the oa of the C. ovata, Flor. Per.* Not being re- 
ceived in commerce, _they_ mingle it with the Huanuco and 
other barks; but it~ is s chiefly employed in forming the extract 
which is sent from Peru. When used alone in the extract of 
Panao, it yields a guonger bitter than that of the C. mag gnifolia, 
but not so transpare 
_ M. Zea thinks ‘that os yellow Quinquina or C. cordifolia 
is the same species; but M. Ruiz, though of the same opi- 
nion, is yet disposed to believe that the specimens and barks of 
the cordifolia, upon which he has founded his opinion, having 
suffered a little in the carriage still leaves some doubts as to this 
identity +

_* Foliis ovatis subtus tomentosis, paniculé brachiatd, floribus sub-corymbosis, corollis 
purpureis: limbo hirsuta. It grows in the woods of Puzuzu and Panao, flowers from June to 
October, attains the height of ten yards, and is remarkable Lo ~_ size of its leaves after aa 
magnifolia, — 
+ The difference of the specific names given on the spot by the authors of the Flora Peru- 
viana and by Mutis, seems to confirm the doubt of M, Ruiz,
