A Proposal of Japanese Terms for Cotyledon Areoles and Seed-Coat inside Areoles of Legume Seeds

Abstract

Many species of subfamily Papilionoideae of the family Leguminosae have a spot on the abaxial surfaces of mature seed cotyledons (Endo and Ohashi 1997). The spot makes an impression on the surface of the endosperm layer inside of the seed coats, formed by pushing the cotyledon areole on the surface. The spot and impression were named ‘cotyledon areole’ and ‘seed-coat inside areole’, respectively (Endo and Ohashi 1997). In the present report, we propose Japanese names ‘Shiyômon’ 子葉紋 and ‘Nainyûhan’ 内乳斑 for the spot and the impression, respectively.
