Tribe II, Zantiioxyle^e. — Trees or shrabs. Leaves pinnate or 3-folio- 

 j late with opposite leaflets or l-foliolate (truly simple in Geijera), the leaflets 



usually large. Ovary lobeJ. Fruit separating into distinct 2-valved cocci. 

 J^ndocarp persistent or separating elastically. Seeds in most genera albumi- 

 nous; the cotyledons flattened and broader than the radicle, but in a few 

 genera tlie albumen is wanting, and the cotyledons are thick and fleshy. — The 

 tribe difters from Boroniecs more in habit than in any definite character. 



16. BOSISTOA, r. Muell. 



Flowers hermaphrodite? Calyx small, 5-tootlied. Petals 5, valvate or 

 slightly imbricate, with inflexed tips. Disk thick. Stamens 10. Ovarj^ of 

 5 distinct carpels; styles almost terminal, united upwm'ds, but soon sepa- 

 ratmg; ovules 3 in each carpel, superposed. Cocci distinct, large, coriaceous, 

 2-valved; endocarp cartiLaginous, separating. Seeds solitaiy; testa membra- 

 nous; albumen none; cotyledons thick and fleshy, radicle small. — A tree. 

 Leaves opposite, pinnate. Panicles tenninal. 



jlie genus is limited to a single Australian speckles, allied in some respects to Melicope 

 ^a Evoclia, but very different in habit as well as iu the seeds, Nvliich have the structure of 

 docarpus and some other Amcriean genera.
