CASCARILLA ROXA (RED QUINQUINA). 
Ir is supposed that this species was discovered in 1785 or 1786 
- at Riobamba, Cuen¢ga, and Jaen. | 
This Quinquina, more known in France than here, circulates 
very little in the interior commerce of Spain ; it is used by only 
a very small number of practitioners. When it arrived from 
Lima for the first time at Cadiz, the dealers of the latter place — 
paid little regard to it, and it was purchased by the English, 
and sent to England. Sir Joseph Banks wrote some time after- 
wards to Professor Ortega, to apprize him of the good results 
obtained from it, and to request some information on this new 
bark. Several known species are comprised under this name.

This is the red C: ee 
rilla of Ruiz, the red AS of the 
French and English, the vermilion Quinguina of the Portugueze. 
It grows, as we have stated, in the mountains of Riobamba, 
Cuenca, and Jaen, on very elevated spots, cool at night, and 
well exposed to the sun, as do all the other fine species. Its 
exterior surface is rough and furrowed with very distinct trans- 
versal fissures ;* the epidermis of a sallow colour more or less 
dark, with whitish spots produced by lichens and mucors ; 
the internal surface dark red; the thickness one or two lines; 
the bulk from one inch to two inches and a half; the small barks 
are well rolled, the large ones little or not at all; these three 
* The inspection of the plates sent by M, Tafalla to Messrs, Ruiz and Pavon, proves that 
the principal transversal fissures are owing to the insertion of the leaves and stipule; their 
proximity might form one of the characteristics for distinguishing the young shoots,
