tanist, who published a dissertation on the systems of botany m 
1771). Lin. gen. no. 831. Geert. fruct. 1. p. 281. t. 58, 
D. C. prod. 1. p. 522. 
Lin. syst. Monadélphia, Decándria. Calyx naked, per- 
manent, 5-parted, or of 5 unequal sepals, which are connected 
at the base, imbricate in the bud. Petals 5, unguiculate, al- — 
ternating with the sepals, twisted in zstivation. Stamens 10, 
joined into an urceolus at the base at first, but afterwards be- 
coming free and filiform; anthers ovate, twin. Ovary round- 
ish. Styles 5, distinct. Drupe fleshy, enclosing (5 ex Cav. 10 
ex Gert.) 1-seeded carpels, adhering together, with a pendu-

axillary peduncles, sometimes some of which are changed into 
hooked spines. This genus is allied to Malvacee or Byline
