Abstract The demonstration of postzygotic self-incompatibility in Asclepias L. prompted us to reconsider explanations for several unusual features of the Apocynaceae. With such late-acting self-incompatibility, mixed loads of self- and cross-pollen can be extremely wasteful by causing abortion of whole fruits and consequent wastage of both cross-pollen and cross-fertilized ovules. We contend that the evolution of pollinia and loss of carpel fusion in certain Apocynaceae represent adaptations to… Expand
Secretory Tissues and the Morphogenesis and Histochemistry of Pollinarium in Flowers of Asclepiadeae (Apocynaceae)
  • D. Demarco
  • Biology
  • International Journal of Plant Sciences
  • 2014
TLDR
Investigation of the structure and activity of the secretory system related to the morphogenesis of pollinaria and the composition of their secretions in flowers of Asclepiadeae revealed the translator shape is due to the differential activity ofthe secretory cells, which are spatially and temporarily coordinated.

Reproductive biology of Mimosa microphylla and Albizia julibrissin (Fabaceae: Caesalpinioideae) with a new explanation for the evolution of polyads, restricted stigmas, and polycarpelly in the mimosoid clade1
Abstract. Although it is yet to be conclusively established, floral features of many legumes of the mimosoid clade suggest the existence of a highly wasteful late-acting form of geneticExpand
Functional morphology and wasp pollination of two South American asclepiads (Asclepiadoideae-Apocynaceae).
TLDR
The detailed structure of the flowers revealed a complex system of guide rails and chambers precisely arranged in order to achieve effective pollinaria transport, which explains the differences in details of the functioning of the general pollination mechanism. Expand
Evolution of pollen, stigmas and ovule numbers at the caesalpinioid–mimosoid interface (Fabaceae)
TLDR
In this study, pollen, stigmas and ovaries from 62 collections of herbarium material representing 16 genera are examined, using light and scanning electron microscopy, to suggest either a mimosoid or caesalpinioid placement. Expand
A Contribution of the Palynological Criteria in Evaluating the Relationships among some Species of Apocynaceae Sensu Lato
TLDR
Light is shed on the different pollen morphological characters of the species under investigation and whether pollen morphology is considered an additional fundamental tool that helps in explanation of the evolutionary trend within the family is discussed. Expand
Pollen morphology of 25 species in the family Apocynaceae from the Adolpho Ducke Forest Reserve, Amazonas, Brazil
ABSTRACT The Apocynaceae family consists of approximately 4555 species worldwide, distributed among 415 genera. In Brazil, this family is represented by 90 genera and 850 species. The Adolpho DuckeExpand
ADVANCES IN APOCYNACEAE: THE ENLIGHTENMENT, AN INTRODUCTION1
TLDR
The papers here present the most up-to-date overview of the Apocynaceae available at this time and include new results in phylogenetics, taxonomy, biogeography, pollination biology, and a pharmacophagous plant–butterfly interaction involving pyrrolizidine alkaloids. Expand
Floral glands in asclepiads: structure, diversity and evolution
TLDR
Some of the species reported here may have dozens of glands of up to 11 types on a single fl ower, corresponding to the largest diversity of glands recorded to date for a single structure. Expand
Floral Biology and Breeding System of Angadenia berteroi (Apocynaceae): Why Do Flowers of the Pineland Golden Trumpet Produce Few Fruits?
TLDR
Hand-pollinations show that A. berteroi is mostly self-incompatible, with greatest fruit set, fruit length, and seedling emergence resulting from crosses between unrelated individuals. Expand
Function and Evolution of Aggregated Pollen in Angiosperms
TLDR
The ability of orchid pollinia to reduce diminishing returns during pollination may explain both the floral diversity and the widespread occurrence of deceit pollination in this clade. Expand

BREEDING SYSTEMS IN ASCLEPIAS INCARNATA L., A. SYRIACA L., AND A. VERTICILLATA L.
TLDR
A series of experimental pollinations involving three sympatric species provided strong evidence for physiological and/or genetic barriers to hybridization in Asclepias, and it is suggested that the potential for autogamy, combined with floral mechanisms requiring pollination by insects, insure the advantages of both the genetic variability promoted by outcrossing and the reproductive assurance of uniparental reproduction.

Postzygotic Control of Selfing in Hymenaea stigonocarpa (Leguminosae‐Caesalpinioideae), a Bat‐Pollinated Tree of the Brazilian Cerrados
TLDR
The pollination biology and breeding system of Hymenaea stigonocarpa, a common tree of the Brazilian cerrados, were investigated, and Controlled hand‐pollination results indicate the species is basically allogamous. Expand
The tribal position of Fockea and Cibirhiza (Apocynaceae: Asclepiadoideae): evidence from pollinium structure and cpDNA sequence data
TLDR
The results of the DNA analysis provide strong support for Fockeeae as a monophyletic tribe, distinct from Marsdenieae and, to the rest of the Asclepiadoideae. Expand
Structure and function in asclepiad pollination
  • H. Kunze
  • Biology
  • Plant Systematics and Evolution
  • 2004
TLDR
In these higher evolved species, the pollen tubes of one inserted pollinium are all directed into one ovary only, thus enabling the plant to allocate its resources to one carpel only in the frequent case of fertilization by onepollinium. Expand
POLLINATION AND FRUIT‐SET IN ASCLEPIAS: A REAPPRAISAL
TLDR
It is concluded that fruit-set in Asclepias is regulated by the interaction of both mechanical aspects of pollination and physiological aspects of fertilization and fruit development, as well as the relative importance of mechanical versus physiological interspecific isolating mechanisms. Expand
THE RARE ASCLEPIAS TEXANA AND ITS WIDESPREAD SISTER SPECIES, A. PERENNIS, ARE SELF-INCOMPATIBLE AND INTERFERTILE
TLDR
Interspecific crosses of A. texana and A. perennis showed that the two taxa are freely and reciprocally interfertile, with fruit-set levels as high as for intraspecific cross-polli- nations. Expand
THE GYNOECIAL DEVELOPMENT AND SYSTEMATIC POSITION OF ALLAMANDA (APOCYNACEAE)
TLDR
Allamanda exhibits an unusual type of gynoecial development in which the two carpels are free at initiation, but fuse completely during development, resulting in a unilocular ovary with parietal placentation at maturity, providing further evidence of the isolated position of Allamanda within the Apocynaceae.

Pollen morphology of the Periplocoideae, Secamonoideae, and Asclepiadoideae (Apocynaceae)
Among Apocynaceae the Periplocoideae are distinguished from the Secamonoideae and Asclepiadoideae by the presence of free tetrads or pollinia, which are shed onto spoon-shaped translators afterExpand
Evolution of syncarpy in angiosperms: theoretical and phylogenetic analyses of the effects of carpel fusion on offspring quantity and quality
TLDR
It is shown that the advantage of syncarpy over apocarpy involving increased offspring‐quantity held under conditions of marginal pollination and declined with increasing pollination, and persisted over a wider range of conditions, including under quite high pollination rates. Expand
Pollen-ovule Ratios in Milkweeds (Asclepiadaceae): an Exception that Probes the Rule
TLDR
Data are consistent with the view that agglutination of pollen evolves in concert with ovule number to minimize the likelihood of receiving mixed pollen loads and are not consistent withThe view that pollen-ovule ratios reflect breeding system or pollination efficiency. Expand
