A rather large family of shrubs and trees of Southern temperate and subtropical regions, " chiefly of the Cape of Good Hope and Australia (a few in South America, &c.), with rigid coriaceous leaves, perfect flowers, either regular or irregular, mostly in heads or spikes ; the lobes of the calyx valvate in aestivation ; a stamen borne on each of its four lobes ; the pistil simple and free, forming a mostly dehiscent fruit; seeds with a large and straight embryo, and no albumen. Many of these plants are prized in conservatories for their beauty or sin- gularity : the seeds of a few species ai-e eaten. 902. Ord. SantalaceSB {Sandal-wood Family). Trees, shrubs, or sometimes herbs (their roots inclined to form parasitic attach- ments) ; with alternate entire leaves, and small (very rarely dioe-. cious) flowers. Calyx-tube adherent to the ovary; the limb four- or five-cleft, valvate in aestivation ; its base lined with a fleshy disk, the edo^e of which is often lobed.
