376 safford: classification of rollinia 



ovate or orbicular, 3.5 to 6 cm. long, 3.5 to 5 cm. broad. Peduncles 

 leaf-opposed, often in pairs, sometimes solitary, rarely in 3's, 25 to 

 40 mm. long, bearing a small ovate sessile bracteole near the middle, 

 strigillose with reddish hairs, like the petioles and nerves of the lower- 

 most leaves (prophylla) beneath. Flowers canescent-puberulous ; corolla 

 lobes 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-puberulous. 

 Fruit a solid subglobose syncarpium, 8 to 12 cm. in diameter, the 

 areoles distinctly outlined and terminating in an obtuse beak; peduncle 

 straight and woody, about 5 cm. long; flesh white or cream-colored, 

 juicy, fine-flavored; seeds compressed, 15 to 20 mm. long, 8 to 10 mm. 

 broad, rounded at the apex, gradually narrowing to the base; hilum 

 not prominent; testa thin, brown, wrinkled by the inclosed ruminate 

 endosperm. 



Type material in the U. S. National Herbarium, accompanied by 

 photographs of the flowers and fruit, from a tree growing in the Experi- 

 mental Garden, Miami, Florida, propagated from seed from Para, 

 Brazil, sent by Mr. C. F. Baker in April, 1908 (No. 22512). Flower- 

 ing specimen, sheet No. 865973, collected at Miami, Florida, March 

 11, 1913; fruiting specimen, sheet No. 865976, from the same tree, 

 August 30, 1912; both collected by Edward Simmonds, in charge of 

 the Miami garden. 



This plant was introduced into the United States under the name 

 Rollinia orthopetala, but it is readily distinguished from that species 

 by the decurved wings of the corolla. Both flowers and fruit were 

 received by the writer from Mr. Simmonds, through the kindness of 

 Mr. P. H. Dorsett, Plant Introducer, Bureau of Plant Industry, in 

 charge of Introduction Field Stations. Mr. C. F. Baker describes 

 its fruit, known in Brazil as the "biribd of Para," as the finest annona- 

 ceous fruit of Tropical America. The accompanying illustration 

 (fig. 2) is from a drawing of type material by Mrs. R. E. Gamble. 



Rollinia Pittieri Safford, sp. nov. 



A forest tree with leaves glaucous beneath and abruptly acuminate. 

 Blades of the vegetative leaves elliptical or obovate, 16 to 20 cm. long, 

 7 to 8.5 cm. broad, the midrib and primary nerves (16 to 20 on each 

 side) reddish brown beneath; leaves of flowering branches smaller, 

 with 10 to 12 pairs of lateral nerves. Pedicels in clusters of 3 or 4, 

 straight or curved, graduated in length, the longer ones 35 to 50 mm. 

 long, minutely rufous-puberulent, bracteolate near the middle. Flowers 

 minutely puberulent, as though composed of felt; calyx and spheroid 

 base of the corolla rufous; calyx lobes triangular, acute or acuminate, 

 appressed to the corolla, the tips reflexed; corolla wings 15 to 20 mm.
