Hence, the nectar robbers apparently limited themselves to piercing holes only in the wall of the hypanthium
, without harming anthers, stigmas, ovaries or androgynophore.

length were no different from Florigraze and none of the lines were observed to produce pegs, pods, or seed.
The flowers are pentamerous, with a shallow, thick, well developed hypanthium, semicircular (U-shape) to cupulate in shape (Fig.
saportanus the sepals are continuous with the hypanthium with no clear attachment point.
The fins (or wings) may be derived from ovary outgrowth, perianth, hypanthium, or bract elaboration.
The pedicel-like structure with no obvious scars, corresponds to the elongate receptacle or hypanthium typical of extant Combretaceae and the epigynous perianth remnants indicate that the fruit developed from an inferior ovary.
On the other hand, Judd and Skean (1991), suggested that Pachyanthus may be a monophyletic group because its species show moderate to large six-merous flowers (secondarily five-merous), more or less robust fruits with a cylindrical-campanulate hypanthium that is coriaceous and persistent (often torn into segments similar to sepals), and inflorescences with flattened axes usually bearing only one to seven flowers.
blancheanus have an uncommon feature: a completely inferior ovary, but with the peripheral portion of the locules extending laterally up into the hypanthium, thus extending beyond the ovary apex, i.e., the point at which the ovary joins with the style.
Sagraea) also have these characters, but Mecranium can be distinguished from Clidemia (including Sagraea) by the reduced external calyx teeth and a fringe of hairs or scalelike erose structures on the torus of the hypanthium
