This species is characterized principally by the short-pedunculate female 
flower heads and the pulverulent indument of the lower face of the leaves. 
Coussapoa panamensis Pittier, sp. nov. 
A tree; branchlets terete, glabrous, the younger parts sparsely covered with 
very short, white, appressed hairs. 
Leaves coriaceous, the petioles minutely puberulous or glabrescent, 3.5 to 6.5 
em. long, the blades ovate, rounded at the base, acute or acuminate at the apex, 
11 to 18 cm. long, 7.5 to 11 cm. broad, glabrous and more or less muriculate 
above, felted-canescent’ beneath; margin sinuate; venation subprominent on 
the upper face, very prominent on the lower face, the straight primary veins 
glabrescent or puberulous, anastomosed along the margin, the venules also 
glabrescent, dark and distinct on the whitish background. Stipules velvety 
without. 
Male inflorescence not known. Female inflorescences single or geminate in 
the upper axils; peduncles terete, simple, 4 to 5 cm. long, thicker at the apex, 
minutely pubescent; flower heads depressed-globose, about 1.5 em. long and 2 
cm. in diameter; flowers bractless, densely congested ; perianth tubular, thick, 
about 3 mm. long, minutely puberulous at the apex, the apical pore round; 
ovary obovoid; style very short; stigma papillose. Drupe ovoid, about 8 mm. 
long, densely appressed-hairy, surrounded by the loose, accrescent perianth, 
Type in the U. 8S. National Herbarium, no. 678968, collected along Rfo Faté, 
Province of Col6n, Panama, in forest, female flowers only, July 9, 1911, by 
H. Pittier (no, 3892). 
By the unbranched peduncles of the female inflorescence, this species is 
related to the South American C. fontanesiana, C. asperifolia, C. villosa, and 
Cc. martiana, as well as to C. brevipes Pittier from the same region in Panama. 
It differs, however, from each one of them in some details, nor can it be readily 
identified with any of the other species of Central America. The Central 
American species of Coussapoa are in need of revision. 
FOUR NEW SPECIES OF CECROPIA. 
Cecropia arachnoidea Pittier, sp. nov. 
A tree 5 to 8 meters high, sparingly branched, the branchlets short, undi- 
vided, the younger parts densely ferruginous-villous. 
Stipules ferruginous-pubescent, about 7 em. long, the apex twisted into an 
acute tip. Leaves coriaceous; petioles plurisuleate, more or less ventricose at 
the base, 22 to 53 cm. long, at first ferruginous-pubescent, glabrescent later, 
the basal pulvinus brown-velvety ; leaf blades 35 to 45 cm. in diameter, scabrous 
above, whitish-pubescent beneath with the very prominent, puberulous cost 
and veins more or less sparsely covered with short white hairs; lobes 8 to 10, 
parted from one-half to two-thirds of the distance from the center to the 
apex, broad, obtuse, their margins entire; larger lobe 30 cm. long, 13.5 em. 
broad ; smallest lobe about 14 cm. long. 
Inflorescences pedunculate, the peduncles geminate in the axils, flattened, 
covered with a minute ferruginous pubescence interspersed with sparse long, 
white hairs, Spathes white-arachnoid, not contracted at the base, cuspidate, 
about 5 cm. long. Male inflorescence: peduncles 8.5 cm. long, erect; aments 
25 to 30 in the cluster, 2.5 to 4 cm. long, about 2.5 mm. in diameter, on 
pedicels 0.5 cm. long, villous; perianth tubular or urceolate, flattened at the 
apex, 1 to 1.2 mm. long, opening by an ovate pore; filaments of the stamens 
almost terete, the anthers oblong. Female inflorescence: peduncles 7 to 9.5 
cm. long, pendulous; aments 3 to 5 together, sessile, 6 to 9 em. long, nearly 1
