ROLLINIOPSIS 



2977 



species, from an economic point of view, is R. deliciosa 

 described above, which is readily distinguished from 

 R. orthopetala by its widely spreading decurved corolla- 

 wings. 



8. laurifdlia, Schlecht. ARATICTJ MIRIM. A shrub or 

 small tree with the new branchlets, petioles, peduncles, 

 midrib, and nerves finely appressed-subfurfuraceous 

 puberulent, the fls. and lower surface of the 11. clothed 

 with finer and denser clay-colored puberulence: Ivs. 

 oblong-elliptical or oblong-lanceolate, acuminate, 

 obtusish at the base, 3^-5 in. long, lK~l?5 m. broad; 

 midrib prominent beneath, lateral nerves 10-15 pairs; 

 upper surface apparently glabrous, but as seen under 

 a lens covered with minute appressed white hairs: 

 peduncles solitary or in 2's or 3's, graduated in length, 

 the longest 3 times as long as the petioles (1 in. long), 

 bracteolate at the base, gradually thickening toward the 

 apex: corolla-wings ascending-erect, broadened at the 

 apex, rounded or quite obtuse, 2o m - l n g an d H^' 

 broad near the apex, clothed with minute brownish- 

 argillaceous tomentum: fr. subglobose, about the size 

 of a horse-chestnut, composed of many carpels distinctly 

 outlined and containing an edible, white, mucilaginous 

 pulp with a pleasant sweet taste. This species is based 

 upon 2 flowering specimens collected in Brazil by 

 Sellow (Nos. 809 and 1190). 



9. incurva, Moore. A diffuse shrub with long 

 branches: Ivs. short-petioled, lanceolate or lanceolate- 

 oblong, obtuse, rounded at the base, coriaceous, above 

 glabrous, often glossy, beneath paler, minutely puberu- 

 lous, blades 4-5 in. long, 1J4-2 in. broad, often 

 more or less oblique at the base; midrib impressed 

 above, rather prominent beneath, lateral nerves about 

 12 pairs inserted at a wide angle, undulate near the 

 margin and curving upward: peduncles usually in pairs, 

 sometimes solitary, longer than the petioles (IK in- 

 long), bracteate at the base, and bearing a small brac- 

 teole near the middle, puberulous: fls. yellowish green; 

 calyx-lobes short and rounded, ferrugineous-pubescent; 

 corolla-wings ferrugineous-tomentose, spatulate-oblong, 

 ascending and incurved, %in. long; stamens numerous, 

 crowded; carpels albo-sericeous: fr. not observed. 

 This species described by Spencer Moore, was collected 

 in Santa Cruz, Brazil, by the Matto Grosso expedition. 

 Specimens from the type collection are hi the Herbarium 

 of Columbia University, at the Botanical Garden, 

 New York City. 



AAAA. Corolla-wings compressed, obovate, and ascending. 



(Fig. 3432, d.) 



10. ruguldsa, Schlecht. A shrub or small tree: Ivs. 

 lanceolate, or broadly lanceolate, obtusely and shortly 

 acuminate, acute at the base, on both sides subglabrous, 

 beneath glossy; young branchlets, petioles, and midrib 

 appressed-puberulous: peduncles usually recurved or 

 pendulous and thickened at the apex, warty and puberu- 

 lous like the calyx, >-%in. long: corolla-wings obovate, 

 ascending, rounded or obtuse at the apex, narrowed at 

 the base, tomentose-canescent, %iii. long and r^in. 

 broad: fr. globose, 1-1 ^5 in. diam., with the component 

 carpels forming 20-30 slightly raised rounded areoles; 

 seeds small, pale brown, conoid, somewhat flattened. 

 Type collected in S. Brazil by Sellow. Closely related 

 to R. rugulosa and with very similar fr. but with longer 

 and narrower Ivs. (suggesting those of R. salicifolm), is 

 R. Wdrmingii, R. E. Fries, the type of which was 

 collected on Mt. Tijuca, near Rio de Janeiro, by 

 Glaziou (No. 6079). 



AAAAA. Corolla-lobes or -wings short, straight and spur- 

 like, horizontally directed. (Fig. 3422, e.) 



11. lanceolata, R. E. Fries. A small tree with small 

 lanceolate Ivs.: Ivs. acute at the apex and base, above 

 glabrous except along the midrib; beneath densely fer- 

 rugineous-villous along the midrib: young branches, 

 petioles, and solitary or rarely geminate peduncles fer- 



rugineous-tomentose: fls. ferrugineous-hirsute; outer 

 corolla-lobes spur-like, short, rounded, and widely 

 spreading: fr. not observed. This species is based by 

 Robert E. Fries on a specimen in the Copenhagen Her- 

 barium collected by Glaziou hi Brazil (No. 13509). 



AAAAAA. Corotta-lobes or -wings broadly ovate or suborbic- 

 ular, and compressed. (Fig. 3422, /.) 



12. emarginata, Schlecht. A glabrescent shrub, &%- 

 10 ft., growing in marshy places, with slender branches: 

 Ivs. oval or elliptical, obtuse at both ends or acutish at 

 the base, emarginate or retuse at the apex, on both sides 

 subglabrous and opaque: peduncles usually solitary, 

 slender, about 1 in. long, minutely bracteolate at the 

 base: corolla and calyx silky-hirtellous; corolla-wings 

 obovate-orbicular, widely spreading, laterally com- 

 pressed: fr. solid, about 1-1 K i- diam., ovate-globose, 

 with the component carpels scarcely at all raised or 

 distinctly outlined. This species, very common in 8. 

 Brazil and Paraguay, is based upon specimens col- 

 lected hi the province of Rio Grande do Sul by Sellow. 



13. glaucescens, Sond. A glabrescent shrub closely 

 allied to R. emarginata, but with the Ivs. not emarginate 

 and sometimes acute at the apex: If .-blades ovate or 

 lanceolate, obtuse or rarely acute at the apex, acute at 

 the base, 2-3 hi. long and 1 hi. broad, glaucescent 

 beneath; petioles X~%. long: peduncles in pairs, one 

 shorter than the other, the longer one bearing a small 

 bracteole below the middle: fls. canescent-puberulous; 

 corolla-wings broadly obovate or suborbicular, widely 

 spreading: fr. broadly ovoid or subglobose, small 

 (about 1 hi. diam.), solid and smooth, with the com- 

 ponent carpels scarcely outlined and not at all gibbous. 

 Specimens hi the U. S. National Herbarium collected 

 by Dorsett, Shamel, and Popenoe, hi S. Brazil. This 

 species was based by Sonder on a plant collected by 

 Regnell on his second expedition, in the province of 

 Minas Geraes, Brazil. 



14. sylvatica, St. Hil. AKATICTT DO MATO. A medium- 

 sized tree: Ivs. elliptical or oblong, shortly acumi- 

 nate, acute, or obtuse at the apex, acutish at the base, 

 above puberulous when young, at length glabrous, 

 beneath softly tomentose; petiole, midrib, and veins 

 clothed with ferrugineous hairs, the remainder of the 

 lower surface with white hairs: peduncles solitary or in 

 pairs, clothed with ferrugineous tomentum; corolla- 

 wings suborbicular: fr. globose, solitary, the size of a 

 small apple, pubescent, with the component carpels form- 

 ing prominent pentagonal areoles; pulp edible, somewhat 

 like that of the cherimoya. W. E. SAFFORD. 



ROLLINIOPSIS (Greek derivative, signifying Rol- 

 linia-like, from the form of the fl.). Annonacese. 

 FRUCTA DE MACACO. MONKEY-FRITH-. Shrubs or small 

 trees of Brazil having fragrant 3-winged fls. like those 

 of Rollinia, but with aromatic frs. in the form of a 

 cluster of small distinct drupes, instead of a fleshy sweet 

 syncarpium, as hi Rollinia. Only 4 species have thus 

 far been described, all from Trop. Brazil. The type of 

 the genus (R. discreta, Safford), Fig. 3425, has been 

 successfully intro. into cult, in the S. U. S. by the Office 

 of Foreign Seed and Plant Introduction, U. S. Dept. of 

 Agric. (S. P. I. No. 15508). This species, discovered 

 by Dorsett, Shamel, and Popenoe in the vicinity 

 of Januaria, state of Minas Geraes, has orange-colored 

 pear-shaped drupes, locally known as Fruta de Macaco 

 (monkey-fruit). The thin aromatic mesocarp sur- 

 rounding the solitary seed tastes very much like the fr. 

 of certain species of Xylopia, called malaguetas in the 

 vicinity of Panama, and also suggests the flavor of the 

 Mexican xochinacaztli, or earflower (Cymbopetalum 

 penduliflorum) the spicy petals of which, together with 

 vanilla, were used by the Aztecs for flavoring then- 

 chocolate in pre-Columbian times (see Cymbopetalum). 

 The other known species are R. simidrum, Safford, 

 recently discovered by Rose and Russell, of the Carnegie
