Trees. Leaves alternate, evergreen, penni-nerved. Flowers 
hermaphrodite, in short racemes or umbels in axillary or terminal

filaments short; anthers basifixed, elongate, 2-celled, the cells 
rounded over the top. Ovary 4—6-celled; ovules solitary in each 
cell, pendulous, anatropous; style filiform, geniculate-flexuose ; 
stigma clavate. Fruit a subglobose, irregularly loculicidally dehis- 
cing capsule; pericarp very thick. Seeds usually 1—2 only, globose 
or oblong, pendulous; testa crustaceous, tegmen membranous; 
albumen 0; cotyledons large, fleshy, plano-convex ; radicle minute, 
superior.—DistRIs. One genus. 
This Family was described by Gilg in Engl. & Prantl Naturl. Pflanzen- 
fam. Nachtr. 231 (1897) to receive the genus Gonystylus which had been placed 
in Thymeleaceze by previous authors. It comes, according to Gilg, just before 
Tiliacere but is Monochlamydeous.
