Adenoa is a monotypic genus of flowering plants belonging to Turneroideae (Passifloraceae).[1]
A. cubensis (Britton & P.Wilson) is currently, the only species assigned to Adenoa.[1][2] It is a shrub native to southeast Cuba.[1] Originally, classified as Piriqueta cubensis, it would later be reclassified as Adenoa by MM Arbo in 1977.[3][4]
A. cubensis is a diploid species (2n=14), which chromosomes similar in size to that of Turnera but larger than that of Piriqueta.[5]
A. cubensis has white homostylous flowers (3 cm) with protruding styles, free penduncles (1.5 cm), and short pedicels (0.5 cm).[5][6] The stamen of A. cubensis are free, similar to those found in Piriqueta.[7] The anthers are obtuse. Overall, the flowers of A. cubensis are considered more complex than those found in Erblichia but simpler than those found in Turnera and Piriqueta.[5]
In addition to the differences in flower complexity, there are differences between A. cubensis' pollen exine and the exine of other members of Turneroideae.[5]
