 vai-elj (Tjr/fti)iie/cia.") 3-merous ; calyx short, imbricated. Gamo- 

 petalous corolla more or loss high tubular; lobes valvate, finally 

 recurved at apex. Stamens twice as numerous as petals, 2-seriate

 annular crenate disk; filaments free ; anthers introrse, 2-riraose. 

 Germen (in male flower rudimentary) 2-5-locular; style capitate-2- 

 5-lobed, stigmatiferous at apex. Drupe ; pyrenas 2-5, with diificulty 

 or not soluhile, 1-spermous; seeds descendent; cotyledons of 

 albuminous embryo plano-convex, rugose or contortuplicate. Other 

 characters of Bwsem. — Balsamic trees ; leaves alternate or suboppo- 

 site, imparipinnate ; folioles opposite coriaceous ; inflorescence
