A 2002 morphological study by Rudall treated possessing an inferior ovary as a synapomorphy of the Asparagales, stating that reversions to a superior ovary in the'core Asparagales'could be associated with the presence of nectaries below the ovaries.
22.
In some fruits, especially simple fruits derived from an inferior ovary, other parts of the flower ( such as the floral tube, including the petals, sepals, and stamens ), fuse with the ovary and ripen with it.
23.
Iridaceae is distinctive among the Asparagales in the unique structure of the inflorescence ( a ripidium ), the combination of an inferior ovary and three stamens, and the common occurrence of unifacial leaves whereas bifacial leaves are the norm in other Asparagales.
24.
The hermaphrodite flowers are urn-shaped, green or tinged reddish, and consist of five basally connate perianth segments ( tepals ), 3-5 ?2-3 mm, 5 stamens, and a semi-inferior ovary with 2-3 wind-pollinated.
25.
However, as Leins & Erbar ( 2010 ) pointed out, " the classical view that the wall of the inferior ovary results from the " congenital " fusion of dorsal carpel flanks and the floral axis does not correspond to the ontogenetic processes that can actually be observed.
26.
The bisexual flowers consist of ( 3-) 5 basally connate perianth segments ( either greenish, dorsally ridged and with hooded tips, or petaloid and whitish, yellowish, reddish, or greenish ), 5 stamens, and a semi-inferior ovary with 2-3 (-5 ) stigmas.
27.
It is unknown what the petals and stamens looked like, as none have been found, possibly being shed during fruit formation . " Dillhoffia " was most likely a non-magnoliid angiosperm as indicated by is inferior ovary, but placement into a specific family is not possible with the fossils known.
