ley) in the Province of Jauja and Department of Junin. 
Through the efforts of Hasskarl, living plants of C. Pa- 
hudiana were established by the Dutch in their planta- 
tions in Java, but, owing to the poor quality of the bark, 
its cultivation was eventually abandoned. Howard has 
given a full description and much historical information 
about this species. The writer has collected ample ma- 
terial of this tree which locally abounds in the moist 
timberline forests of the upper Chanchamayo Valley 
along the auto road between 'Tarma and San Ramon and 
not far from the type locality. The description which 
follows is based on these recent collections: 
Cinchona Pahudiana Howard Ill. Nuev. Quinol. 
Pavon (1862) pl. 21. 
A small, often slender tree 5-7 meters high, 5-20 cm. 
in diameter; bark thin, gray to brown’, the branchlets 
pilose, the hairs usually shed below the second girdle ; sti- 
pules 14-85 mm. long, 7-17 mm. wide, oblong-elliptical, 
obtuse (rarely acutish), pilose on the outer surfaces; 
leaves petiolate; the petioles 83-10 mm. long, pilose or 
often densely tomentose; blades oblong-elliptical to 
ovate or obovate, 8-28 cm. long, 4-15 cm. wide, the tip 
rounded to obtuse, rarely acute, the base acute, decur- 
rent onto the petiole, glabrate or sparingly hairy usually 
on the veins above, generally yellowish-pilose below with 
longer denser hairs on the veins, with 9-12 pairs of pri- 
mary lateral veins; panicles many-flowered, terminal, 
' Dried samples of bark have a strong lateral curvature and often 
show narrow longitudinal ridges; there is also a strong tendency for 
the outer cork layers to shed. Samples analyzed by the U.S. Govern- 
ment Cinchona Mission Laboratory in Lima (as were all others men- 
tioned in this paper) indicate that the species is of little value com- 
mercially, a typical analysis of trunk bark of Hodge 6243 yielding 
total alkaloids 4%, anhydrous quinine 0.53%, quinine sulfate 0.65%, 
cinchonidine 1.02%, quinidine traces, total crystallizable alkaloids 
28%.
