On the “Cangaço” route: a new species of Hymenaea (Leguminosae) from the Brazilian Caatinga

Biological activities associated with tannins and flavonoids present in Hymenaea stigonocarpa and Hymenaea courbaril: A systematic review

“…Studies carried out with different parts (stem, roots and leaves) of Hymenaea species show that they have tannins, flavonoids, coumarins, amino acids and some carbohydrates in their composition (Oliveira de Veras et al, 2020;Oliveira et al, 2010;Veggi et al, 2014), which could explain the curative effects of this genus and its popular use (Boniface et al, 2017;Lacerda et al, 2014;Pinto et al, 2017).

It's raining fragrant nectar in the Caatinga: evidence of nectar olfactory signaling in bat‐pollinated flowers

“…Diverse floral parts, including nectar, can produce their own distinct scents and pollinators may use this scent variation among different flower parts to detect resource availability (Raguso 2004, D€ otterl andJ€ urgens 2005). There are some indications of fragrant nectar in batpollinated plant species, but they are restricted to subjective descriptions based on human olfaction (e.g., Vriesea spp., Bromeliaceae;Sazima et al 1995) or to identification of compounds that are very likely of microbial origin (Agave palmeri, Agavaceae; Raguso 2004).Hymenaea cangaceira (Fabaceae), a recently described species (Pinto et al 2017) endemic to the Caatinga (a seasonal tropical dry forest found in northeastern Brazil) is another striking example of a bat-pollinated species that produces large amounts of nectar. Hymenaea cangaceira first drew our attention because of its massive flowering and second by its abundant and fragrant nectar.…”

Systematic studies in the Hymenaea clade and a taxonomic revision of the genus Hymenaea L. (Leguminosae, Detarioideae)

“…Hymenaea cangaceira occurs in the Caatinga region of Northeastern Brazil(Bahia, Ceará and Pernambuco states), usually on sandy or rocky soils. Hymenaea cangaceira was recently described byPinto et al (2017) based on outstanding collections of the Brazilian Caatinga. In the context of the genus, the new species is similar to H. martiana and H. longifolia in having ovate to broadly-elliptic leaflets, brownish fruits, and a geographical distribution that overlaps those of both species.…”
