 2-4-celled ; cells 2-oo-ovuled. Style subulate ; stigma shortly 2-4-lobed. 

 Drupe 1-4-stoned, entire or lobed. Stones 1-2 or more-seeded and divided

 quently covered with stelliform hairs. Leaves entire or lobed, 3-7 -nerved. 

 Plowers yellow or pink, in axillary or terminal cymes. 



An extensive genus whose species are for the most part tropical and subtropical. Many 

 of the species are exceedingly variable, and not a little difficult of discrimination in the dried 

 state. Possibly some of the forms here kept separate will have to be combined when further 

 material shall be examined. 



Cymes axillary, subaxillary or opposite to the leaves. Drupes fleshy. 

 Peduncles erect, much longer than the petioles. Serratures of 



leaves glandular 1. G. columnaris. 



Peduncles shorter or not greatly longer than the petioles. Serra- 

 tures not glandular. (See G. gtandulosa.)
