“…(sensu Fritsch et al, 2008), a monophyletic group with ca. 26 species (including those described here) in the Americas and one species in eastern Asia (Fritsch et al, 2008). The section is characterized by a basally connate corolla, stamens that are adnate to the corolla only at the base and either completely distinct or united only at the base, terete filaments, a 3carpellate ovary, hermaphroditic or with a dioecious breeding system (morphologically androdioecious through similar appearance of staminodes to stamens in flowers of female plants), a 1-locular fruit with one seed, rarely 2-or 3-locular with two or three seeds, and an embryo with the radicle longer than the cotyledons, rarely shorter than the cotyledons (Brand, 1901;Fritsch et al, 2008).…”
