Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen-rewarding Caribbean bloodwort. [PDF]

open access: yesAm J Bot
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Biosilicification in monocots: Comparative analysis highlights contrasting patterns of deposition. [PDF]

open access: yesAm J Bot
Abstract Premise New insights into biomineral uptake and sequestration are important for understanding how plants grow. Some plants accumulate silica accretions in precise locations in particular cells. Among monocots, controlled biosilicification occurs in several different forms and is restricted to commelinids and orchids. Methods We utilized energy‐

Evolution, Systematics and Classification of Commelinales (Commelinids, Monocots) Based on a Giant Morphological Taxon-Character Matrix [PDF]

open access: yesPlants
Despite being strongly recovered as monophyletic by molecular studies, Commelinales completely lacks any morphological support or circumscription. It is also the Monocot order that suffered the most striking changes across different classification ...

Total evidence phylogeny of Pontederiaceae (Commelinales) sheds light on the necessity of its recircumscription and synopsis of Pontederia L. [PDF]

open access: yesPhytoKeys, 2018
A total evidence phylogeny for Pontederiaceae is herein presented based on new morphological and previously published molecular data. Our results led us to re-circumscribe Pontederia to include Monochoria, Pontederia s.s. and the polyphyletic Eichhornia.
