Adenoa cubensis

A. cubensis is a shrub 1-3 meters tall, with leaves described as oblanceolate or obovate, 4-8 cm long and 1-2.2 cm wide. Seeds are described as pyriform. A. cubensis lacks glandular hairs and has vegetative colleters.

Flower morphology. A. cubensis has white homostylous flowers (3 cm) with protruding styles, free penduncles (1.5 cm), and short pedicels (0.5 cm). The stamen of A. cubensis are free, similar to those found in Piriqueta. 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. In addition to the differences in flower complexity, there are differences between A. cubensis' pollen exine and the exine of other members of Turneroideae.

A. cubensis is native to southeast Cuba. It can be found in La Mensura-Pilotos, Pico Cristal, and Alejandro de Humboldt national parks, and Loma Miraflores Managed Flora Reserve. Herbarium specimens have been collected between Rio Yamaniguey and Camp Toa, Oriente Province, and Sierra de Nipe.
