382 safford: classification of rollinia 



the apex, narrowed at the base, tomentose-canescent, 8 mm. long, 

 4 mm. broad. Fruit globose, 2.5 to 3 cm. in diameter, the component 

 carpels forming 20 to 30 slightly raised, rounded areoles. Seeds 

 small, pale brown, conoid, somewhat flattened. 



Type in the Berlin Herbarium, collected in southern Brazil by Sellow. 



Closely related to R. rugulosa and with very similar fruit but longer 

 and narrower leaves (suggesting those of R. salicifolia Schlecht.) 

 is R. Warmingii R. E. Fries, the type of which was collected on Mount 

 Tijuca, near Rio de Janeiro, by Glaziou (No. 6079). 



GROUP E 



COROLLA LOBES SHORT, STRAIGHT AND SPURLIKE, HORIZONTALLY 



DIRECTED 



Rollinia lanceolata Fries, Svensk. Vet. Akad. Handl., 34 5 : 49, pi. 6, 

 fig. 6. 1900. 



A small tree with small leaves, the blades lanceolate, acute at the 

 apex and base, above glabrous except along the midrib, beneath densely 

 ferruginous-villous along the midrib. Young branches, petioles, and 

 solitary or rarely geminate peduncles ferruginous-tomentose. Flowers 

 ferruginous-hirsute; outer corolla lobes spur-like, short, rounded, and 

 widely spreading. Fruit not observed. 



Type in Botanical Museum of Copenhagen, collected in Brazil by 

 Glaziou (No. 13509). 



GROUP F 



COROLLA LOBES BROADLY OVATE OR SUBORBICULAR AND LATERALLY 



COMPRESSED 



Rollinia emarginata Schlecht. Linnaea, 9: 318. 1835. 



A glabrescent shrub 2 to 3 meters high, growing in marshy places, 

 with slender branches. Leaf blades, thin, membranaceous, oval or ellip- 

 tical, 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 25 mm. long, minutely bracteolate at the 

 base. Corolla and calyx silky-hirtellous ; corolla wings obovate-orbic- 

 ular, widely spreading, laterally compressed. Fruit solid, about 25 

 to 30 mm. in diameter, ovoid globose, the component carpels scarcely 

 at all raised or distinctly outlined. 



Type in the Berlin Herbarium, collected in the province of Rio 

 Grande do Sul, Brazil, by Sellow. 



This species is very common in southern Brazil and Paraguay. 

 It is distinguished from most of its congeners by its small smooth 

 fruit and emarginate leaves.
