Description :   The Fabaceae family includes approximately 16,400 species - including trees, shrubs, herbs and lianas - and is divided into three large subfamilies: Caesalpinoideae, Mimosoideae and Papilonoideae (Espinoza & Melandri 2000). The existence of anatomical similarities between genera, tribes and subfamilies of the Fabaceae makes their taxonomic identification very difficult. This charcoal was classified within this subfamily due to the presence of homocellular rays in its anatomy and the absence of a stratified structure (Espinoza & Melandri 2000). Transversal plane: Growth ring marked by narrowi...

Description :   20 charcoal fragments corresponding to cf. Manilkara sp. This genus includes species that cannot be differentiated on the basis of their anatomical characteristics (Kukachka 1981), but Manilkara zapota is the only one that grows in dry tropical forests (Condit et al. 2011). Transverse plane: the growth rings are not marked and have a diffuse porosity. The rounded vessels with radial or diagonal distribution in groups of 2-4, feature tylids and deposits in their interior. The parenchyma is apotracheal, diffuse, in narrow bands or in lines of up to 3 cells, reticulated or scaleriform. Tang...
