. Botany for high schools and colleges. Botany. 508 BOTANY. Armeria vulgaris, Thrift, of Europe, is cultivated in flower-gardens. Plumbago; several South African and East Indian species, are to be met vv^ith in conservatories. 586.—Cohort XVIII. Ericales. — Plants with regular flowers, and superior two to many-celled ovaries ; stamens as many or twice as many as the corolla lobes, hypogynous or epipetalous. Order Lennoacese.—Californian and Mexican leafless root-parasites. Order Diapensiacese.—Low plants (six to eight species) of North America and Eastern Asia, of much botanical, but no economic interest. Order Ericaceae.—The Heath Family. Mostly shrubs or small trees, a few herbs, with usually alternate, simple, and entire leaves ; ovary mostly five-celled, with placentae in the axis ; anthers opening by a terminal pore, rarely by a lateral slit; pollen grains compound, rarely simpiC. Under these characters are included about 1700 species, which ar» often regarded as constituting five orders, viz., Ericiiieae, Epacrideae, Pyrolinese, Monotropeae, and Vacciniese, here to be considered as sub- orders. While, however, there are considerable differences between the plants here brought together, they are not important enough to counterbalance the many evident resemblances. The relationship sub- sisting between the sub-orders may be shown as follows : VACCINIE^. 77 (Ovary inferior.) EPACRIDE^. <- f Stamens epipetal-") J ous or hypogyn- ! 1 ous ; anthers I [with a slit.
