A rough-barked tree, with broad entire or 1-3-lobed deciduous leaves, and yellow dioe- 

 cious flowers in involucrate umbelled racemes at the ends of twigs of the preceding season, 

 unfolding with or before the leaves, the involucre composed of the persistent bud-scales. 

 Calyx 6-parted, that of the pistillate flowers persistent, its segments equal. Staminate 

 flowers with 3 series of 3 stamens, the 2 outer series with glandless filaments, those of the 

 inner series with a pair of stalked glands at the base. Anthers all 4-ceIled and introrse, 

 4-valved. Pistillate flowers with about 6 staminodia and an ovoid ovary. Fruit an oblong-

 Trees or shrubs, with entire leaves, deciduous in our species, and small greenish or yel-

 axillary, or in the following species unfolding before the leaves at the nodes of twigs of 

 the previous season. Calyx 6-parted, deciduous. Staminate flowers much as in Sassafras, 

 bearing 3 series of 3 stamens, their anthers all 4-celled, 4-valved and introrse. Pistillate
