Perianth cut and opened, showing tepals connate basally by proximal submarginal lamellae. E. Proximal part of flower in cross section. Two larger arrows point connate portions between adjoining tepals, and two smaller arrows indicate margins of tepal. F. Stigma (st) and adaxial side of anther (in spirit). Portion of anther affixed to filament indicated with 'F'. Thecal connation below insertion point of filament indicated with arrow. F; filament. IF; inner filament. OF; outer filament. OVB; basal inside of ovary. Scale at B also for C, D and F.
