rounded, the other acute; stipules slender, hairy, short, deciduous. Flowers 

 2 cm in diameter, white, extra-axillary, solitary or in pairs, their pedicels 

 erect, 1.5 to 2.5 cm long. Sepals 5, green, reflexed, lanceolate, long-acumi- 

 nate, 1 cm long. Petals obovate, deciduous, 1 cm long, spreading. Stamens 

 many. Fruit a globose, red, smooth, very fleshy, sweet berry, about l.B 

 cm in diameter, filled with very numerous, small seeds. (Fl. Filip. pi. iSS.)

 indehiscent. (In honor of G. B. Trionfetti, and Italian botanist.) 



A genus of about 40 species of wide tropical distribution, about 6 in the
