MASCULUS FLOS, a male flower; a flower which contains the stamina, reckoned by the sexualists the male organ of generation, but not the stigma or female organ.

All the plants of the class dicœcia of Linnaeus have male and female flowers upon different roots: those of the class monœcia, bear flowers of different sexes on the same root. The plants, therefore, of the former are only male or female: those of the latter are androgynous; that is, contain a mixture of both male and female flowers.
