CINCnOiyA IX THE EAST IXDLES. 17 



flowering branch brought by Mr. R, Cross with the seeds which 

 he collected for India. This is now before the Society. I should 

 call this the var. Bonplandiana^ adding the descriptive term colo-^ 

 rata or lutea, according as we have to do with the form called 

 colorada del Bey^ or the amarilla del Rey^ which last is not, I 

 think, known in India. 



The var. crispa may retain its name, which is descriptive. It 

 is singular that the distinctive properties of the bark should so 

 permanently outlive the change of soil and climate, and also that 

 whilst the colorada del Itey has so greatly improved, this is the case 

 in small degree with the var. crispa. The nomenclature would thus 



be free from contradiction, which it is not at present ; and the 

 names both of La Condamine and of Bonpland might be retained 

 with complete consistency. 



Tlie remarkable plan of successful cultivation by renewal of the 

 bark, in reference both to the C. succiruhra and C, officinalis^ var. 

 Bonplandiana, has long been practised at Loja, as will be found by 

 the details given to me by Don T. Riofrio, and recorded in my 

 * Illustrations of the Nueta Quinologia ' under the head C, uritu- 

 singa ; but Mr. M'lvor was the first, so far as I am aware, 

 to save the plant itself from the injurious results of the process. 

 A drawing under the microscope, by Burgess, will show the 

 anomalous formation of the bark in these Cascarillas resacadas. 



As regards the bark of Cincliona PaTitidianay the results are new 

 and striking. It appears, as I have said elsewhere, to indicate a 

 sort of mean between the extreme depreciation in which it has 

 been held by some parties and the commendation lavished on it 

 by others. I lay before the Society specimens showing, as I ap- 

 prehend, the entire distinctness of the plant from the C Carahay- 

 ensis of Weddell, and its derivation from the C. crespilla chica of 

 Hasskarljby whom it was introduced into Java. It appears to be 

 rather superior in point of produce of alkaloid to the fine bark of

I think, deserve to be cultivated, I have expressed myself so 

 fully on this point, in a communication to the Botanical Congress 

 of 1866, that I need not add much here. I have great hopes of 

 the produce of the seed recently introduced from the best pro- 

 vince of Bolivia as yielding one or more sorts of Calisaya rich in 

 quinine, and repaying to the cultivator. The var. frutex seems 

 rather to deteriorate than to improve in India.
