Characteristics of some Species of Cinchona- 
Vani, in his excellent Monograph, augmented by Lambert, 
divides all the species into two groupes of plants, floribus to- 
mentosis, staminibus inclusis, and floribus glabris, staminibus 
exsertis. This division possesses this fault, that two characters 
are placed opposite each other, which are by no means observed 
at one and the same time in all the species at present known. Cer- 
tainly no Cinchona with tomentose flowers has long projecting sta- 
mens, for in the East Indian species the anthers are merely visi- 
ble; but. there are Cinchonz which have, like C. parviflora, Mut. 
and C. grandiflora, Flor. Peruv. a smooth corolla and inclosed 
stamens. With more, although not with perfect justice, we 
might separate Cinchonz staminibus inclusis, stigmate. bilamel- 
lato, seminum ala denticulatA vel lacera, and Cinchone filamen- 
tis insertis ex imo tubi nascentibus, seminibus membrana inte- 
gra cinctis. However, it seems more correctly logical to divide 
the Cinchone into. those with smooth and into these with hairy 
corollas. The first division | merely subdivides itself, according 
to the length of the stamens, into two smaller tribes, and (what 
is certainly an important object) all the useful and eae 
species associate into one groupe.
