the older fibrous bark light to dark gray or brown, marked 
with short rather indistinct transverse fissures; branch- 
lets thick, four-angled, with very dense brown pilose 
hairs, internodes elongate; stipules erect, soon decidu- 
ous, oblong, 12-35 mm. long with an obtuse tip, densely 
hispidulose on the outer surface, glabrous on the inner 
surface; leaves medium-sized, petiolate, subcoriaceous, 
bullate or rugose, especially when fresh, margins con- 
spicuously inrolled, particularly on the younger leaves; 
petiole thick, 1-2 cm. long, densely hispidulose-tomen- 
tose with brownish hairs ; blades oval-elliptical to oblong, 
6-19 cm. long, 3-9.5 em. wide, with apex rounded or 
obtuse and subapiculate, base obtuse to truncate, above 
often at first densely appressed-pilose, later glabrate, with 
veins and veinlets deeply impressed, below everywhere 
densely hispidulose and with short loose brown to yel- 
lowish hairs; midrib thick, usually reddish above for about 
a third of its length, prominent below with approxi- 
mately 12-16 pairs of conspicuous lateral veins; panicles 
small to medium-sized (8-30 cm. across), terminal, at 
least the younger branches densely hairy, leafy bracteate 
at the base, many-flowered, the sessile flowers densely 
aggregate, ultimate bracts linear, 3-4 mm. long; hypan- 
thium 2-3 mm. long, densely fulvous-tomentose; calyx 
3-4 mm. long, generally reddish, densely fulvous-tomen- 
tose, toothed to the middle, the triangular teeth erect, 
acute; corolla maroon (the color somewhat obscured on 
the tube and outer surface of lobes by the dense ad- 
pressed strigose hairs, but visible in the throat of the open 
flower), 12 mm. long, with lobes much shorter (2 mm. ) 
than tube; capsule up to 25 mm. long, woody with a 
rough-pubescent outer surface, seeds 7-8 mm. long, nar- 
rowly elliptical. 
I made several collections of C. parabolica in northern 
Peru during the period 1948-1945, and some of my field
