6 CINCHONA LEDGERIANA A HYBRID. 
Cinchona Ledgeriana originated a in the government 
plantations - Mungpo in Sikkim, as published by me in my 
inchona. Dr. Trimen did not know this fact, and 
- would seem that he has not read my monograph; for he writes 
. 822), «I made inquiries of Mr. Moens, vpande assured me that he 
a saw anything like —e + wale me from seed of a 
Calisaya. I under mand t t Mr. Gammie S si same experience.” 
During my visit to Java rn never observed spontaneous C. Ledgeriana, 
but in Mungpo-Sikkim Mr. Gammie and the late Mr. Biermann 
assured me that ‘ C. Ledyeriana had originated spontaneously there 
in the = soe ” Besides Dr. Trimen supports this state- 
itient, sa ‘‘TIn our own plantations in Sikkim, after years of 
neglect as one of is ecabianian and hopelessly variable forms of 
C. ees ny the plant (C. Ledgeriana) is now the object of careful 
cultiva os r. ‘'rimen is therefore in error to aa that ‘all 
existing plants in the East are descendants of seeds collected . 
in B , in June, 1865.” 
But the testimony of the Cinchona cultivators—valuable as it 
be—is not necessary, for we know a fact that proves the 
hybrid a of C. pen ae in Mun ngpo. : the papers Cinchonas 
the art of the cultivators, who prefer trees for bark collecting. 
When I visited Mungpo C. Ledgeriana was mostly not yet tree-like. 
contrast to this shrubby Ledyeriana of Mungpo the descen- 
dants of Bolivian Ledgeriana in Java and Southern India, perhaps 
also in private Sikkim plantations, are veritable trees. I do not 
know if there has been imported Bolivian Ledgeriana to the Mungpo 
government plantations after 1875; but until that date no Bolivian 
Ledgeriana existed there. 
The M o Ledgeriana shows another individual mark, by 
which I can easily distinguish it from Bolivian Ledgeriana; the 
former has very divaricate panicles with slender ramification, the 
such slender divariolts panicles, and all its hybrids at Mungpo, as © 
well as C. Ledgeriana, show that individual orga The Mungpo 
Calisaya-field is of very great extension, and it is the same place 
on which the former intendant of that Shntaiitn, Mr. C. B. Clarke, 
sowed = Calisaya. . Mr. Clarke said in November, 1875, to me, 
“We sowed Calisaya and got other plants,” and among these 
other aids were many shrubs of C. Ledgeriana. 
am anxious to correct the erroneou int of Dr. Trimen’s 
Ledgeriana; he says also ‘‘ Messrs. Moens and Trimen prove that
