in the neighbourhood," itself showing all the indications of pre- 
mature decay. The tree was evidently a survival of the early 
plantations. Dr. Trimen says, “Trees of five or six years old 
have been found on several estates mingled with other varieties, 
and generally unrecognized until the characters were pointed out 
by Mr. Moens during a visit to the island in Sept. 1880." 
The whole identification, as it seems to me, rests on Mr. 
Moens, for whose scientific knowledge and skill as a chemist I 
have the highest respect. It is consequently to be regretted that 
no analysis or description of the bark is added. This is highly 
important, as I shall endeavour to show. 
Sir J. D. Hooker published, in Curtis's ‘ Botanical Magazine,’ 
under the head Cinchona Calisaya, var. Josephiana, “a very 
distinct-looking form of Cinchona Calisaya,” which I should 
myself have preferred calling C. micrantha, var. Calisayoides. 
The drawing is from a plant flourishing and flowering in my 
possession in 1872, received as a small plant from Kew, and 
derived originally, according to the same authority, from South 
America. A comparison of the plate in the ‘ Botanical Magazine’ 
with those in the ‘ Journal of Botany’ by Dr. Trimen will show 
a close analogy, and perhaps identity, when it is considered that 
mine is the hembra and Dr. Trimen’s the macho form, to which 
circumstance the difference in the length of the flowers may be 
due, as also the colouring of the underside of the leaf. 
Though botanically of interest, this * Micrantha Calisayoides” 
is quite evidently to be avoided in cultivation. 
Tam the more free to suggest the possibility of mistake in the 
identification of this published Ceylon variety with the specimens 
sent me by Mr. Moens himself from Java, and which I published 
as C. Calisaya, var. Ledgeriana, How., because I have myself been 
deceived by, as I think, the very same variety, which I received 
from high authority as the seed of C. Ledgeriana, and cultivated 
for years with great care, having the mortification also to have 
sent it out as real Ledgeriana to Dr. Morris in Jamaica. 
Last year one of my small trees failed me (as seems to be 
often the case) and I have cut it down the less reluctantly, 
because I could then analyze the bark. Behold the result!
