270 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
flowering branches subreniform and often retuse; upper obovate leaves (young speci- 
mens only observed) 7 cm. long and 4 cm. broad; orbicular leaves 5 or 6 cm. in diame- 
ter; lowermost emarginate leaves 3 to 4 cm. in diameter; all of them membranaceous, 
punctulate, above velvety-pubescent and at length glabrate except along the 
impressed midrib, beneath clothed with dense soft fulvous or pale rufous tomentum 
on the prominent midrib and lateral nerves (8 to 12 on each side) and with grayish or 
olivaceous tomentum between the nerves; lateral nerves of the lowermost leaves con- 
nected by veins at right-angles to them; peduncles short, solitary, 1-flowered, extra- 
axillary, 7 to 9 mm. long, densely clothed with tomentum like that of the young 
branchlets and bearing a small tomentose bracteole below the middle; sepals broadly 
ovate-triangular, 4 or 5 mm, long, obtusely acuminate, clothed on the outside with 
dense fulvous tomentum; petals 3, broadly ovate, 12 mm. long and 10 or 11 mm. 
broad, acute or obtuse, thick and leathery, clothed with short pale brown velvety 
tomentum without and within; receptacle convex, clothed with straight erect pale 
fulvous hairs between the stamens and carpels; stamens numerous, 2 to 2.5 mm. long, 
the connective expanded above the parallel linear pale yellow pollen sacs, its surface 
velvety, densely covered with short fine brown hairs; carpels 1.5 to 2 mm. long, 
entirely clothed with pale fulvous hairs and bearing broadly ovoid or spheroid stig- 
mas, these densely covered with erect pale fulvous or straw-colored hairs and resem- 
bling minute echinate burs under the lens, at the time of pollination becoming suf- 
fused with a viscous brown fluid and at length falling off; fruit not observed, but 
undoubtedly short-peduncled and velvety. (Piates 90, 91, B.) 
Type in the U. S. National Herbarium, no. 592568, collected on the wooded hills 
of Nicoya, Pacific coast of Costa Rica, May, 1900, by A. Tonduz (no. 13930); 
duplicate in the herbarium of the New York Botanical Garden. 
DisTRIBUTION: Pacific coast of Costa Rica; known only from the type locality. 
Annona holosericea is distinguished from all its congeners by its orbicular leaves 
and its velvety essential parts, of which both the connectives of the stamens and the 
outer stigmas (before becoming cemented together at the time of pollination) are con- 
spicuously hairy, as seen under the lens. The connectives differ from those of the 
stamens of A. sericea and its close allies in being covered with very many fine hairs 
instead of comparatively few coarse ones, and the stigmas resemble miniature echinate 
burs instead of being covered with rounded tubercles as in the species referred to.

VELVETY ANNONA OF PANAMA. 
A tree 6 to 16 meters high; ultimate branchlets rufous-tomentose when young, soon 
becoming glabrescent, and at length glabrate, with reddish brown bark thickly dotted 
with small whitish lenticels; old leaf scars prominent, lined with dense rufous tomen- 
tum; leaves distichous; petioles (of young leaves) 7 to 9 mm. long, densely rufous- 
tomentose; blades oblong-lanceolate to obovate-oblong, 10 to 20 cm. long and 3 to 6 
cm. broad, acuminate at the apex and rounded or obtusely cuneate at the base, 
pellucid-punctulate, sparsely pubescent above with scattered grayish hairs, densely 
and softly sericeous-pubescent beneath with appressed grayish olivaceous hairs except 
along the rufous-tomentose midrib and lateral nerves; lateral nerves 20 to 26 on each 
side, prominent beneath; blades of the lowermost leaves on the flowering branches 
rounded or retuse at the apex, cuneate at the base, much smaller than the rest, some- 
times obcordate; flowers 3-petaled, large, yellow, subglobose in bud; peduncles 
solitary, extra-axillary, usually issuing from a point near the base of a young branchlet, 
9 to 14 mm. long, ferrugineous-tomentose, with a small ovate bracteole above the
