Flowers dioecious, apetalous. Disk 0. Male flowers : Calyx-segments 

 or lobes 4-5, rarely 6, imbricate. Stamens usually 5, opposite the calyx- 

 segments ; filaments rarely exceeding the calyx, connate at the base into a 

 very short column or free ; anthers large, at first reflexed, usually adorned 

 with a conspicuous yellow or golden-coloured gland on the back, cells 

 distinct, parallel, dehiscing longitudinally. Rudimentary ovary as long 

 as the filaments, bifid or entire. Female flowers : Sepals distinct, narrow, 

 caducous. Ovary 2-celled, compressed in the opposite plane to that of 

 the septum ; styles 2, free from the base, long, subterete or flattened 

 in the same plane as the ovary, undivided, papillose or glabrous ; 

 ovules 2 in each cell. Capsule flat, of 2 compressed very broadly 

 winged cocci, separating from a central axis ; pericarp crustaceous^ 

 reticulate ; endocarp membranous. Seeds usually solitary in each 

 coccus, compressed ; testa thin ; albumen not copious ; cotyledons thin, 

 broad and flat ; radicle long. — Trees or tall shrubs. Leaves alternate, 

 petiolate, membranous or coriaceous, entire, penninerved. |Male in- 

 florescence a catkin-like spike, female shortly racemose.
