the branches generally tomentose, leafy-bracteate at the 
base, ultimate bracts linear, approximately 2 mm. or 
less long; hypanthium 2 mm. long, densely tomentose ; 
calyx 2 mm. long, sparingly pubescent to glabrate par- 
ticularly at anthesis, dentate nearly to the middle, the 
teeth erect, triangular-acute; corolla shell pink with a 
deeper redder shade on outer surfaces, tube 12 mm. long, 
limb 4 mm. long; capsule 10-80 mm. long, lanceolate, 
becoming much broader in extreme dehiscence, pubes- 
cent to glabrate, prominently 10-costate. 
As stated above, C. Pahudiana is a small tree, never 
shrubby like C. carabayensis. In general habit it more 
closely resembles weedy forms of C. pubescens Vahl sensu 
lat., and indeed it might perhaps better be included in a 
subspecific category of that species. As with a number 
of other cinchonas, the degree of pubescence among in- 
dividual trees in a stand shows considerable variation and 
this variability is especially to be noted in the juvenile 
population. Nevertheless, C. Pahudiana in its typical form 
seems to be easily identified and readily separable from 
C. pubescens both in the field and in the herbarium, 
because of its rather small, thick, generally tomentose 
leaves with bases decurrent onto the short petioles.
