Seed and seedling morphology, and seed anatomy of Lasiopetaleae (Malvaceae s.l. or Sterculiaceae)

Abstract

Seed and seedling morphology and seed anatomy of Lasiopetaleae sensu Whitlock et al. (Malvaceae s.l.) and related genera are described. All seed of Lasiopetaleae, except Maxwellia, have arils that develop adjacent to the funicle. Some species have flexible, stellate hairs on their seeds. Seed size, shape, aril form, presence of hair and exotesta pattern can be definitive at generic and/or specific levels.
