Dinemandra and Dinemagonum, the only two genera of Malpighiaceae in Chile, have calyx glands borne on stalks rather than appressed to the surfaces of the calyx lobes as is typical of malpighs. It is proposed that this positioning of the glandular secretory surfaces (elaiophores) on the ends of stalks provides an intergland distance and surface area needed for the robust Centris bees that serve as pollinators. The structure of the stalked calyx glands and similarities in pollen provide evidence… Expand

Comparative leaf anatomy in Ptilochaetoids clade (Malpighiaceae): A taxonomic and phylogenetic approach
This work characterized the leaf anatomy of seven species of the Ptilochaetoide clade and listed relevant anatomical patterns for their circumscription and reaffirm the effectiveness of leaf anatomy in taxonomic and phylogenetic studies in Malpighiaceae. Expand
Structure and secretion mechanisms of floral glands in Diplopterys pubipetala (Malpighiaceae), a neotropical species
Results show that each gland in sepals, petals and connective tissues of Diplopterys pubipetala has a peculiar mechanism and type of secretion, suggesting additional levels of floral specialisation for interactions with pollinators. Expand
Structural diversity of elaiophores in Argentine species of Malpighiaceae: morphology, anatomy, and interaction with pollinators.
The main objectives are to describe the morphology and anatomy of the elaiophores, to detect variation in the number of glands, to compare similarities or differences in elaiophile of species belonging to different lineages, and to know about the potential pollinators and their association with the structural traits of theElaiophore.

Pterandra pyroidea: a case of pollination shift within neotropical Malpighiaceae.
Eglandular flowers represent a shift in the pollination system in which oil is being lost and pollen is becoming the main reward of P. pyroidea flowers, and provide an opportunity to study ongoing evolutionary mechanisms that promote the persistence of species previously involved in specialized mutualistic relationships.

Elaiophores in three Neotropical Malpighiaceae species: a comparative study
Differences identified in relation to the location of the glands on the sepals, in the fine structure of secretory epithelia and cuticle architecture, and in their secretion release mechanisms, in some way, can affect the behavior of visitors. Expand
Anatomy of staminal glands in the Stigmaphylloid clade sheds light into new morphotypes of elaiophores and osmophores in Malpighiaceae
The nature of the staminal glands from 25 Stigmaphylloid species aiming to characterize their micromorphology, anatomy and exudate histochemistry are identified and should shed light on the remaining lineages of this family. Expand
An unusual kind of nectary in the oil flowers of Monttea: its structure and function
The presence of two rewarding systems, i.e. oils and nectar, is here considered in relation to the pollination biology and the pollinators of Monttea schickendantzii and M. chilensis are recorded for the first time. Expand
Floral Lipid Chemistry of Byrsonima crassifolia (Malpigheaceae) and a Use of Floral Lipids by Centris Bees (Hymenoptera: Apidae)
Oil collected from the scopae of two representative Centris species was the same as the type one oil collected from B. crassifolia type one floral elaiophore oil with the exception of several minor ninhydrin positive compounds which may have been derived from the pollen which makes up part of the larval food provisions.

Biologia de nidificação de Centris (Hemisiella) trigonoides Lepeletier (Hymenoptera, Apidae, Centridini)
Centris (H.) trigonoides females showed defensive behaviors to avoid parasitism, such as chasing the parasites and guarding the nests, which suggests that males and females have distinct temporal activity patterns. Expand
Advances in the floral structural characterization of the major subclades of Malpighiales, one of the largest orders of flowering plants.
Although the current phylogenetic reconstruction of Malpighiales is much improved compared with earlier versions, it is incomplete, and further focused phylogenetic and morphological studies are needed. Expand


Floral Conservatism in Neotropical Malpighiaceae
The purpose of this paper is to consider southwestern United States to temperate Argentina, why the flowers of this family have remained so conservative in spite of the evolution of great diversity in other aspects of the phenotype. Expand
