Schizocarp, a dry, indehiscent fruit splitting into separate one-seeded segments (carpels) at maturity; “a pericarp which splits into one-seeded portions, mericarps, or ‘split-fruits’” (Fernald 1950); “a dry compound fruit that splits at maturity into several indehiscent one-seeded carpels” (WIII); see mericarp [ > Gk. schizo- ‘split’ + karpos, fruit]: schizocarpium,-ii (s.n.II), abl.sg. schizocarpio, nom. & acc. pl. schizocarpia, dat. & abl.pl. schizocarpiis; cf. mericarp, = “one of the two carpels that resemble achenes and form the schizocarp of an umbelliferous plant” (WIII); see coccus,-i (s.m.II); see pericarp;

“Some botanists call all fruits, the carpels of which separate from each other without opening — schizocarps; and term their component carpels ‘cocci’ if there are more than two, or if only two in number, as in the Umbelliferae, —‘mericarps’.” (Bentley).

Coccus,-i (s.m.II), q.v., abl. sg. cocco: “When such carpels separate with a certain amount of elasticity from the axis to which they are attached, as in some Euphorbiaceae, they have been called cocci. By some botanists, all carpels which thus separate from the axis in a septicidal manner are termed cocci, and the fruit is described as dicoccous, tricoccous, &c, according to their number.” (Bentley).

Mericarp, mericarpium, that is “one of the half fruits of an Umbellifer: it is a carpel ripened and separated from a common axis or growing point” (Lindley): mericarpium,-ii (s.n.II), abl. sg. mericarpio.

Regma,-atis (s.n.III), q.v., abl.sg. regmate: regma, a fruit with elastically dehiscing segments or cocci as in Euphorbia; “a tricoccous fruit like that of Spurges [Euphorbia]. Any such fruit, whether the number of cocci is three or not” (Lindley).
