Rollinia deliciosa, Safford. Biriba. Fig. 3423. A tree yielding a delicious, large, juicy fr., resembling the cherimoya: vegetative lvs. obovate-oblong or elliptical, rounded at the base and normally acuminate at the apex, blades 8-11 in. long and 3-4 in. broad, membrana- ceous, when young sparsely canescent-hirtellous above, densely so beneath, especially along the midrib and nerves, at length glabrous above and beneath except along the midrib and primary nerves (18-22 on each side), these reddish brown and slender but prominent beneath; petiole about 2/5in. long: lvs. on flowering branches smaller, the lowermost ones relatively shorter and broader, sometimes broadly ovate or orbicular, 1 2/5-2 2/5 in. long and 1 2/5-2 in. broad: peduncles lf.- opposed, often in pairs, sometimes solitary, rarely in 3's, 1-1 3/5 in. long, bearing a small ovate sessile brac- teole near the middle, strigillose with reddish hairs, like the petioles and nerves of the lowermost lvs. (prophylla) beneath: calyx and corolla canescent- puberulous; corolla-wings compressed laterally, widely diverging and decurved, rounded at the extremity; stamens numerous, closely crowded, the expanded connectives forming a pavement above the pollen-sacs; carpels numerous, ovaries hairy, styles expanded, glandular-puberulpus: fr. a solid depressed subglobose syncarpium, 3-5 in. diam. with the areoles distinctly outlined and terminating in an obtuse beak; peduncle straight and woody, about 2 in. long; pulp fleshy, white or cream-colored, juicy, fine-flavored; seeds compressed, 3/5-4/5in. long and 8-25-2/5in. broad, rounded at the apex, gradually narrowing to the base, hilum not prominent; testa thin, brown, wrinkled by the inclosed ruminate endosperm.—The type of this species, in the U. S. National Herbarium, is from a fr.-bearing tree cult, in the experiment station, Miami, Fla., grown from seeds sent by C. F. Baker from Para, Brazil (No. 22512) in 1908. Baker describes it as the finest annonaceoua fruit of Trop. Amer. It was incorrectly referred to R. ortho- petala, but it is readily distinguished from that species by the decurved wings of its fls.

which is readely distinguished from R.orthopetala by its widely

spreading decurved corollawings.
