C. CALISAYA, VAR. LEDGERIANA, AND C. LEDGERIANA. 821 
ance of the leaves is highly characteristic of the “ glorious Ca- 
lisaya ^ of the American forests, and contrasts strongly with the 
micrantha-looking plant, which is a descendant of the pseudo- 
Ledgeriana which I sent to Jamaica, not having then the oppor- 
tunity of comparison which I now possess. 
The leaves of the plant figured as C. Ledgeriana, Moens, are 
apparently glabrous, and devoid alike of the peculiar and charac- 
teristic appearance of the upper surface represented by Dr. 
Weddell, pl. ii. fig. 19, of his ‘ Histoire.’ This he describes as 
** epidermie " cellules of the upper surface of the leaf, each one 
of which forms a conical projection. 
A magnified hair is seen segmented (“ clozssonné ") and punc- 
tuated, taking its origin from the upper surface. This, again, is 
characteristic; and in the richer species of Calisaya which I show, 
this feature is even exaggerated, as will be seen on examination 
by the microscope; and a delicate fringe of these minute hairs 
forms a conspicuous surrounding to the edge of the leaf, in con- 
trast to all the sorts of micrantha. The set of the veinlets in 
Dr. Trimen’s plate is again different from that of the plant of 
true Ledgeriana, which I show. 
With the exception of Mr. Ledger*, I believe that no one has 
obtained true seed of the more valuable sorts of C. Calisaya except 
Mr. Christy, who will, I trust, favour us with his account. 
Through the kindness of this gentleman, I received a small 
quantity of the seed in his possession, which I sowed at the 
same time with the Ledgeriana seed above. Both came up alike, 
and for months no difference could be perceived between the pro- 
duce of the Indian and South-A merican seed; possibly the former 
were less vigorous. I raised some two or three dozen of each, 
with the usual results of a certain amount of variation combined 
with general resemblance. In the case of Mr. Christy's seed I 
have distinetly the verde and the morada varieties. 
lean now compare all these with the plates of Cinchona Ca- 
lisaya, var. Ledgeriana. These were drawn by Mr. Fitch from 
* « Schuhkraft, Consul for the Netherlands, more than thirty-five years in the 
country, married to a lady possessing estates in the Yungas, the major part of 
whose tenants are bark-cutters, carriers, and all knowing what bark is. With 
all these immense advantages he never was able to obtain seed of any value ” 
(Ledger, Sept. 28th, 1880). Weddell, Hasskarl, and Markham equally failed.
