Secundine
Secundine Sec"un*dine, n. [Cf. F. secondine.] 1. (Bot.) The second coat, or integument, of an ovule, lying within the primine. [1913 Webster]

Note: In the ripened seed the primine and secundine are usually united to form the testa, or outer seed coat. When they remain distinct the secundine becomes the mesosperm, as in the castor bean. [1913 Webster]

2. [Cf. F. secondines.] The afterbirth, or placenta and membranes; -- generally used in the plural. [1913 Webster]
