Rrunoideae contains five genera, the species of which are distributed through the north temperate zone, passing mto the tropics: they are characterised by a free solitary carpel with a terminal style and a j^air of pendulous ovules, and the fruit a one-seeded drupe. With few exceptions the torus forms a more or less deep cup at the edge of which sprmg the five sepals, five alternating petals and 10. 20 or more stamens. The stony endocarp bears a longitudinal seam along which it splits m germination. The seed (kernel) consists cliiefiy of two large fleshy planoconvex cotyledons; there is no endo-.
