Examples

Although fossils dating back to the Cretaceous and Palaeocene have been referred to the family by various authors, none of these fossils has been confirmed as belonging to the Rubiaceae. Source: Internet

Although most Rubiaceae species are hermaphroditic, outbreeding is promoted through proterandry and spatial isolation of the reproductive organs. Source: Internet

Heterodistyly is another mechanism to avoid inbreeding and is widely present in the Rubiaceae family. Source: Internet

Description The Rubiaceae are morphologically easily recognizable as a coherent group by a combination of characters: opposite leaves that are simple and entire, interpetiolar stipules, tubular sympetalous actinomorphic corollas and an inferior ovary. Source: Internet

However, Dialypetalanthus is morphologically quite aberrant in Rubiaceae and if it should be excluded from Rubiaceae, the subfamilial name remains Ixoroideae. Source: Internet

In general, problems of subfamilies delimitation in Rubiaceae based on morphological characters are linked with the extreme naturalness of the family, hence a relatively low divergence of its members. Source: Internet
