pericarp Bot.|ˈpɛrɪkɑːp|
[= F. péricarpe (1556 in Hatz.-Darm.), It. pericarpio (Florio), ad. 16th c. L. pericarpium, a. Gr. περικάρπιον pod, husk, shell, f. περί around + καρπός fruit. In earlier use in the L. form: see pericarpium1.]
A seed-vessel; the case containing the seed or seeds, comprising the outer shell, rind, or skin, and the enclosed pulp, etc. if any; the wall of the ripened ovary or fruit of a flowering plant. (See endocarp, epicarp, mesocarp.) Also applied to a special structure containing the spores in certain cryptogamous plants, as the cystocarp of florideous algæ.
1759B. Stillingfleet Misc. Tracts, Biberg's Œcon. Nat. (1762) 63 Most of the pericarps are shut at top, that the seeds may not fall. [Note] Whatever surrounds the seeds is called by botanical writers a pericarpium, and as we want an English word to express this, I have taken the liberty to call it a pericarp. 1785Martyn Rousseau's Bot. x. (1794) 99 A bilocular pericarp, or seed-vessel of two cells. 1835Lindley Introd. Bot. (1848) II. 3 Every fruit consists of two principal parts, the pericarp and the seed. 1875Bennett & Dyer Sachs' Bot. 236 Articulated branches, which..form the peculiar ‘Pericarp’ of Lejolisia [a florideous alga].
Hence † periˈcarpic a. = pericarpial; pericarˈpoidal a., resembling a pericarp.
