824 MR. J. E. HOWARD ON 
that, by implication, he admits the correctness of my descrip- 
tions. 
I must add a word about my form B and Dr. Flückiger's 
plate ii. This seems to be represented by a plant which I show 
tothe Society, raised from seed from Mr. Gammie, Darjeeling ; 
and it must be admitted to resemble at first sight specimens of 
the verde of Christy. It seems, however, that the general cha- 
racter of the tree and of the bark are different *. Ithought that, 
on the whole, I was justified in describing these differing forms 
as one variety of Calisaya, seeing they agree in the extraordinary 
richness of the bark, but not because no other variety was to be 
found in the seed procured by Mr. Ledger. Of this I had proof 
in the plants which I myself raised from a few capsules full of 
seed which I took as a recompense for my trouble. There seems 
no limit to the multiplication of varieties unless they are some- 
what grouped together. I could point out quite a number of 
which I know the bark, but not the botanical descriptiont. The 
Colorada anaranjada (orange-peel red), one of these, is extensively 
cultivated; it is not so good as the Caupolican “ rojo "f. 
These different forms of C. Calisaya, var. Ledgeriana, 1 now 
seek to illustrate by the plants before the Meeting contrasted 
with the C. Ledgeriana, Moens, to which 1 also call the attention 
of the Society. 
According to Manuel, the Rojo (or true Ledgeriana) “is 
never met with in manchas (patehes) like the other classes of 
Cinchona. Itis found by itself here and there " S. 
* The produce per cent. of Mr. Christy's verde is less than that of the 
morada ; but the more vigorous growth makes it more desirable for culti- 
vation. 
t One of these, which I described as C. Forbesiana, amd from which Mr. 
M'Ivor took out young plants, resembles much the plant of Trimen. 
1 “I repeatedly used to joke poor Manuel when he used to tell me the 
trees from which the thick heavy slabs of bark, in fact the * Rojo,’ came from had 
white flowers. The ‘Rojo’ from Corioco and in South Yungas, although with 
purple leaves (underside), are nothing to be compared with the * Rojo' of Cau- 
polican and Apolobamba. This ‘Rojo’ or Ledgeriana is very little known in 
Bolivia even.” —Ledger, Feb. 7, 1881. 
* When the ‘Rojo’ trees are in flower, the leaves are ‘red’ underneath ; 
when the seed is ripe and the leaves falling, they are a dark purple. Old trees 
in particular have on the branches a species of rough moss of a brilliant scarlet 
and bright silver colours."— Nov. 24th, 1875.
