Anatomy, pollen, and chromosomes of adenoa (turneraceae), a monotypic genus endemic to Cuba

The monotypic genus Adenoa is endemic to Cuba. Its name alludes to the presence of minute glands on the petal margin, identified in the present study as lachrymiform colleters. Here we describe the morphological, anatomical, palynolog ical, and chromosome features that characterize Adenoa cubensis....

Its name alludes to the presence of minute glands on the petal margin, identified in the present study as lachrymiform colleters. Here we describe the morphological, anatomical, palynolog ical, and chromosome features that characterize Adenoa cubensis. The indumentum of Adenoa consists only of stellate trichomes. Unlike many species of the new world genera Piriqueta and Turnera, Adenoa lacks glandular hairs and extrafloral nectaries. Adenoa, Piriqueta, and Turnera share the presence of standard, sessile, and lachrymi form colleters. The leaves of Adenoa have xeromorphic features, which include entire, revolute blade margins, an adaxial hypodermis, and stomata restricted to the abaxial surface. The chromosome number is 2n=14, which is probably the ancestral number of the family. Adenoa chromosomes are similar in size to those of Turnera, and are larger than those of Piriqueta. Using the available data, we discuss relationships among the new world genera of Turneraceae. 2021-08-12T13:06:57Z 2021-08-12T13:06:57Z 2012 Artículo González, Ana María, et al., 2012.
