A family of dicotyledonous plants of the order Polemoniales; includes figwort and snapdragon and foxglove and toadflax and speedwell and mullein; in some classifications placed in the order Scrophulariales
Euphorbiaceae and Scrophulariaceae and Orchidaceae are universally present, the last in specially large proportions.
Such are Papilionaceous flowers, Violaceae, many Labiatae, Scrophulariaceae and others.
The orders most abundantly represented are the Compositae, Cruciferae, Labiatae, Caryophyllaceae and Scrophulariaceae.
Advance has been along two lines, markedly in relation to insect-pollination, one of which has culminated in the hypogynous epipetalous bicarpellate forms with dorsiventral often large and loosely arranged flowers such as occur in Scrophulariaceae, and the other in the epigynous bicarpellate small-flowered families of which the Compositae represent the most elaborate type.
The herbaceous vegetation does not differ greatly, generically, from that of the east, and many species of Primulaceae, Ranunculaceae, Cruciferae, Labiatae and Scrophulariaceae occur; balsams abound, also beautiful forms of Campanulaceae, Gentiana, Meconopsis, Saxifraga and many others.
