Biosystematic studies inErythronium (Liliaceae-Tulipeae)

II. Floral anatomy ofE. japonicum decne
  • Frederick H. Utech

The floral anatomy ofErythronium japonicum has been investigated, and its major features include a pedicel with a central core of major bundles surrounded by numerous smaller ones from which all traces arise. Each perianth member receives three bundles: a median from the central region and two laterals from the peripheral region. Episepaly and epipetaly of the filaments occur basally around a slightly stipitate ovary. The two cycles of stamens which have different filaments lengths are positioned by the differently lobed auricles of the mature sepals and petals which also form an inverted trap-lid nectary. The six stamen bundles have a double fusion origin, as do the three carpel dorsals and three carpel laterals. The derivation of the six single ventrals are from the fused carpel dorsals. THe dorsals which branch laterally and anastomose with the ventral supply are continuous from the base of the gynoecium to the stigmatic region, while the fused laterals terminate without any branching in the upper, inner septal regions. The common, hollow stylar canal is continuous with the three locules. The gynoecium shows no signs of either septal glands or raphides. The bitegmic, anatropous ovules have aFritillaria-type of embryo sac development.
