sites usually are to be found on open ridges generally 
close to timber-line where tree types are replaced by 
shrubby growth and herbaceous or suffruticose peren- 
nials. Where pajonales merge into woodlands, types of 
C. pubescens are found, and this species is of all the cin- 
chonas the closest associate of C. glandulifera. In its 
choice of sites and in its shrubby growth-form, hairy C. 
glandulifera is identical with C. Josephiana Weddell of 
southern Peru. However, the latter plant is easily dis- 
tinguished from the former by well-marked morphologi- 
cal differences, the most obvious being its glabrosity. 
In central Peru this diminutive species with its nar- 
rowly elongate panicles is in flower from at least Febru- 
ary to July. Diagnostic features of C. glandulifera, other 
than its shrub form and hairiness, are the very short cap- 
sules and very small seeds. 
An analysis of a composite sample of bark from several 
individuals of this species from Pomocochas has yielded 
only traces of erystallizable alkaloids, principally cincho- 
nine. Even if the shrub were of value as a source of al- 
kaloids, the small size of the stems would prohibit prof- 
itable commercial exploitation. 
There follows an expanded description of the species 
based on recent collections. 
Cinchona glandulifera Ruiz & Pavon FI. Peruv. 
et Chil. 3 (1802) 1, pl. 224. 
A shrub or oceasionally a small tree 2-5 m. high with 
several trunks, these as much as 7 em. thick; bark ashy 
to dark gray, the outer surface marked with inconspicu- 
ous fine transverse fissures, the youngest branchlets pilose 
or hirsute; stipules 12-40 mm. long, elliptical to oblong, 
obtuse to acute, somewhat villose; leaves subsessile, or 
with short petioles 2-15 mm. long, the blades ovate to 
lanceolate or oblong-elliptic, 6-16 cm. long, 2.5-8.5 em.
