of tomentum covering all parts of young growth includ- 
ing inflorescences; flowers distinctly pink especially in 
bud, fainter when open, the calyx a deeper pink chang- 
ing into deep red as the young green capsule develops. ”’ 
In its densely tomentose habit C. carabayensis differs 
from all other cinchonas known to me from southern 
Peru. The closest relative of this rare tree of the Andes 
of Carabaya appears to be the similarly hairy C. Pahu- 
diana Howard (discussed below), a better-known tree 
of the Chanchamayo Region of central Peru. These two 
species have been considered conspecific by Standley, but 
the writer’s impression from field observation is that they 
are distinct. However, the fragmentary herbarium ma- 
terial of C. carabayensis and Weddell’s rather incomplete 
description make it impossible to compare critically these 
two trees. Howard noted a similarity between the two 
species, but pointed out correctly that one was normally 
a shrub, the other always a tree; he also noted differ- 
ences in the leaves. Until more abundant material of 
C. carabayensis is in hand, it seems best to consider it 
apart, especially since the two species are rather widely 
disjunct. It should be pointed out that C. Pahudiana, 
not C. carabayensis, was the species introduced into cul- 
tivation in Java and elsewhere in the past century. 
In addition to the living plants, the writer has also ex- 
amined material, possibly the type (ex herb. Paris), in 
the herbarium of the Chicago Museum (sheet no. 971880) 
and collected by Weddell in the ** Province of Carabaya. ”’ 
Besides the differences noted above, the capsules of Wed- 
dell’s specimen are much coarser and more woody than 
those of C. Pahudiana. Seed differences may also exist, 
for the ones examined are large in comparison with those 
of most Peruvian cinchonas. It is hoped that botanists 
who may get into this interesting area of southern Peru 
will keep their eyes open for this neglected species.
