2005 Amer. Jrnl. Bot. 92 1598 The most important of these [new stomatal types] is the stephanocytic bicyclic type, which consists of two concentric cycles of cells.

2. Botany. Of a perianth, calyx, etc., or members of a series of floral organs: composed of or arranged in two whorls. Cf. monocyclic adj. 3.
