Ovary inferior, 1–4-celled, crowned by a fleshy disc; style single (3 in Griselinia), long or short; ovules solitary (rarely 2–3), pendulous from the top of the cell, anatropous. Fruit usually drupaceous, indehiscent, 1–4-celled, or rarely with 2 pyrenes. Seed pendulous, testa thin; albumen copious, fleshy; embryo axile, radicle superior.

A small order, scattered over the whole world, but chiefly found in the north temperate zone. Genera 12; species 75. Properties unimportant. Of the 2 New Zealand genera, Corokia is endemic; Griselinia extends to South America.

1. C. buddleoides, A. Cunn. Precur. n. 579.—An erect much-branched slender shrub 6–12 ft. high; young branchlets, undersurface of leaves, and inflorescence densely clothed with silvery-white tomentum. Leaves alternate, shortly petioled, 3–6 in. long, lanceolate or linear-lanceolate, acute or acuminate, coriaceous, dark-green and shining above; veins reticulated. Panicles terminal, leafy at the base. Flowers ¼–⅓ in diam., yellow. Petals oblong-lanceolate. Drupe oblong, ¼ in. long, dark-red.—Hook. Ic. Plant. t. 424; Raoul, Choix, 46; Hook. f. Fl. Nov.
