Peduncles axillary, exceeding the leaves, fulvous-tomentose becoming glabrous. Cymes many-flowered, dense, their primary branches short and their ultimate branches so nearly aborted that the inflorescence appears almost umbellate. Bracts deciduous, entire, the outer ovate, ample and completely enclosing the young inflorescence. Pedicels 5-25 mm. long. Staminate tepals 2, suborbicular, 6-11 mm. long, entire, sparsely pilose to glabrous, white. Stamens numerous, anthers oblong, about equaling the filaments, connective produced, broadly obtuse.
