The genera Eriosema and Rhynchosia, which comprise approximately 150 and 230 species, respectively, belong to the tribe Phaseoleae and to the subtribe Cajaninae. The pollen morphology of 49 species of Eriosema and 13 of ...

Perfect flowers of Maytenus obtusifolia have partial sterility of pollen grains, resulting in collapsed and developed free microspores. However, the cellular events resulting in partial male sterility have not been determined. ...

Croton macrosepalus Sodre & M.J.Silva(sp. nov.), a new species found in the states of Bahia, Goias, and Tocantins, in Brazil, is described and illustrated. Although it is morphologically similar to Croton spica, the novel ...

The Annonaceae family presents alkaloids with ecological functions and pharmacological interest. This is the first study to evaluate if the application of plant growth regulators to seeds of this family alters the production ...

In the Clusia criuva Cambess. species complex, the two subspecies C. criuva subsp. parviflora Vesque and C. criuva subsp. criuva can only be distinguished on the basis of stamen/staminode morphology and geographical ...

1. Plant-animal mutualisms are key processes that influence community structure, dynamics, and function. They reflect several neutral and niche-based mechanisms related to plant-animal interactions. 2. However, the strength ...
