16 MS. J. E. HOWABD OK THE CtTLTIViiTION OF 



Don T. Eiofrio, himself a native of Loja, together with flowering 

 branches and capsules full of seeds of the same plant, from the 

 mountains of Uritusinga, whence the Spanish botanist, Pavon, 

 derived his name for the species. These seeds, having vegetated 

 under my care, I was enabled to present a plant to the Indian 

 Crovemment, from which, up to February of last year, 8219 



plants had been derived. 



This is the C. officinalis of Dr. Hooker. In India, according to 

 a " Memorandum " in the return (ordered to be printed 18th of 

 June, 1866), it is called C. officinalis, var. Condaminea\ and the 

 other sorts there grown are to be named var. Bonplandiana and 



var. crisj^a 



^ 



It seems to me that if any designation is supplemented to the 

 simple O, officinalis, it should be that of Pavon (locally descrip- 

 tive), var. Uritusinga, This would be generally landerstood, as the 

 name is still in constant use. 



In the next place, the species is certainly not either of the 

 forms figured in the ' Plantes Equinoctiales ;' and therefore the 

 designation var. Condaminea is incorrect and tends to confusion, 

 a confusion which already begins to be evident in India ; for in 

 several of the returns all the varieties of Loja-bark are called 

 " Condaminea audits varieties," all being classed together. Now, 

 some of these are proved to be suited to peculiar climates, and 

 should therefore be discriminated. The C officinalis seems spe- 

 cially suited to the climate of the sub-Himalayan aspects (as 

 Darjeeling), as also to Ceylon. The var. crisjpa is specially suited 

 to the summit of the Neilgherries, but seems to abound rather m 

 colouring matters than in the alkaloids peculiar to these Barks. 



The ** Memorandum " states correctly that the Q, Ghahuarguera 

 of Pavon is the plant represented in the unshaded branch with 

 capsules in plate x. of the * Plantes Equinoctiales,' and therefore 

 provides that it shall beao* the name of Bonpland, and be th^ 



variety JBonplandiana. . ^ 



But the above plant, the G. Ghahuarguera of Pavon, is not 

 known at present in India. It is the original source of the 

 " Eusty Crown Barks " of English commerce. I should then call 



w 



this G Ghahuarguera of Pavon the var. /3. Gondaminea. 



The plant to which the " Memorandum" attaches the name is 

 the var. color ada del Bey of the O. Ghahuarguera, according to 

 Pavon ; and if it is represented, as I think, by the bark which I 

 examined, it is a great success, and must be carefully distinguishea 

 by the cultivator. It is represented by an original specimen of d
