ROLLINIA 



ROLLINIA 



areoles rounded at the tips; pulp fleshy, nearly white, 

 melting in the mouth, slightly viscous, with a sugary 

 agreeable flavor. Type collected by Sieber (No. 96), in 

 the De Candolle Herbarium. 



AA. Corolla-wings laterally compressed, widely spreading 



and more or less decurved. (Fig. 8422, b.) 

 4. delici&sa, Safford. BIRIBA". Fig. 3423. A tree 

 yielding a delicious, large, juicy fr., resembling the 

 cherimoya: vegetative Ivs. 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 %in. long: Ivs. on flowering 

 branches smaller, the lowermost ones relatively shorter 

 and broader, sometimes broadly ovate or orbicular, 

 l%-2% in- long and l%-2 in. broad: peduncles lf.- 

 opposed, often in pairs, sometimes solitary, rarely in 

 3's, 1-1% in. long, bearing a small ovate sessile brac- 

 teole near the middle, strigillose with reddish hairs, 

 like the petioles and nerves of the lowermost Ivs. 

 (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 con- 

 nectives 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, 

 %-%in. long and A-%in. 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 annonaceous fruit 

 of Trop. Amer. It was incorrectly referred to R. orlho- 

 petala, but it is readily distinguished from that species 

 by the decurved wings of its fls. 



5. Pittieri, Safford. A tree resembling R. deliciosa, 

 but with Ivs. more abruptly acuminate and glaucous 

 beneath, the vegetative ones 6-8 in. long and 3-3% in. 

 broad, midrib and primary nerves (16-20 on each side) 

 reddish brown beneath: Ivs. on flowering branches 

 smaller (with 10-12 primary nerves): peduncles often 

 in clusters of 3 or 4, graduated in length, the longest 

 1% in. long, rufous, minutely puberulent, never hairy 

 like those of R. deliciosa, bracteolate near the middle: 

 corolla-wings %-Kin. long, falcate, horizontally ex- 

 tended and decurved, rounded at extremity, and nar- 

 rowed at the base, very finely puberulent, appearing 

 under the lens as though composed of olive-gray felt: 

 fr. not observed. A beautiful species with elliptical or 

 obovate Ivs. remarkable for the pale color of the lower 

 surface and the sharply outlined lateral nerves. These 

 correspond with the description of R. rufinerva, Triana 

 and Planch., but the corolla-wings are decurved, not 

 "divergent ascending," as in that species. The type, in 

 the U. S. National Herbarium, was collected near 

 Puerto Obaldia, Panama, by Henry Pittier (No. 4358), 

 in whose honor the species is named. 



6. Jimenezii, Safford. ANONILLA. Fig. 3424. A 

 small tree of Costa Rica resembling R. mucosa but with 

 fls. in clusters of 2 or 3, having the corolla-wings hori- 

 zontally spreading and slightly decurved, and with fr. 

 resembling that of the common sugar-apple (Annona 

 squamosa), with the component carpels rounded at the 

 tips when fresh, but more or less beaked when dry: 

 Ivs. ovate to oblong-elliptical, acuminate, those of the 

 vegetative branches 7-8 in. long and 2%-3 in. broad, 

 obtuse at the base, with 18-22 primary nerves on each 

 side of midrib, those of the flowering branches smaller 

 with 12-16 pairs of primary nerves and usually rounded 

 at the base; point of acumen either acute or more 

 usually obtuse or retuse ; young branches, petioles, and 

 lower surface of young Ivs. covered thickly with ferru- 

 gineous hairs, Ivs. at length glabrous or nearly so except 

 along the midrib and nerves beneath: peduncles lf.- 

 opposed, in clusters of 2 or 3, graduated in length, the 

 longest about %in. long, ferrugineous-tomentose like 

 the ovate-acuminate calyx-lobes: corolla- wings oblong, 

 rounded at the tip, scarcely at all narrowed at the base, 

 widely spreading and usually decurved, never curving 

 upward and inward, ruf ous-puberulent : fr. subglobose, 

 about 2% in. diam., closely resembling that of Annona 

 squamosa, the component carpels loosely adhering, 

 very gibbous, rounded or often retuse at the tip when 

 fresh; pulp white, edible, but not so agreeably flavored 

 as that of Annona squamosa. This species is based 

 upon specimens in the U. S. National Herbarium, 

 received from Oton Jimenez, of San Jose, Costa Rica, 

 the fls. collected by him at Nuestro Amo, March, 1912 

 (No. 427), and the fr. from the same tree, Oct., 1912. 

 The accompanying figure is drawn from type material, 

 the fr. from a field photograph sent by Mr. Jimenez, 

 in whose honor the species is named. 



AAA. Corolla-wings linear-oblong or spatulate, ascending 

 or erect and incurved. (Fig. 3422, c.) 



7. orthopetala, A. DC. A shrub or small tree with 

 the habit of R. Sieberi, but with the Ivs. somewhat 

 longer petioled: Ivs. oval-oblong, acute at apex and 

 base, pilose: peduncles in pairs: calyx-lobes smaller 

 than in R. Sieberi; corolla-wings erect and incurved: 

 fr. not described. This species was described by De 

 Candolle from a specimen in the De Candolle Her- 

 barium collected by Parker near Demarara, British 

 Guiana. The name has been incorrectly applied to 

 several rollinias with edible fr. Of these the principal
