DENDROCOUSINSIA Millsp. gen. nov. 



Flowers dioecious, apetalous; disk none. Female flowers: calyx 

 cupuliform, fleshy, sepals 3, minute, each basally subtended (internally) 

 by a bract fringed with filamentous glands, ovary 3-celled, stigma 3- 

 branched. Male flowers diskless, stamens 3 with 2-celled anthers open- 

 ing by a longitudinal fissure, calyx lobes three, each subtended (inter- 

 nally) by a minute bract with a glandularly fringed margin. Capsule 

 tricoccous, seeds carunculate. 



Trees with thick, coriaceous leaves alternate below opposite or 

 faciculate above, the lateral veins evident and tipped with a minute 

 gland when ending at the margin of the leaf; inflorescence in terminal 

 spikes or clusters, the male and female flowers sessile or appearing so, 

 minute, diskless, each accompanied by two flanking glands.

A small tree. Leaves alternate below, often opposite upon the 

 flowering branchlets, glabrous, pale-green, thick, coriaceous, 4.5-8 cm. 

 long, 3-4.5 cm. broad, oval to orbicular, blunt or slightly emarginate;

 dots; midrib prominent beneath; lateral veins generally opposite and 

 substantially at right-angles to the mid- vein; petioles about 5 mm. long; 

 stipules discoid-glandular. Inflorescence in terminal spikes, the flowers 

 flanked on each side by a nearly globular gland pitted centrally; male 

 spikes glabrous, slender, elongated, about 10 cm., the flowers glabrous, 

 sessile upon a nodular prominence; stamens 3, divaricate, contiguous at 

 the base, filaments rigid, anthers bilocular opening with an erose margin; 

 calyx lobes oval, alternate with the filaments, involute to the appear-
