Dynastid scarab beetle pollination appears basic within the genusAnnona. Those species ofAnnona which are more morphologically derived, as well as allRollinia spp. possess reduced floral chambers and attract small beetles likeNitidulidae orStaphylinidae. Pollination of the primitive species ofAnnona byDynastinae would imply that the genus had not evolved before the Tertiary. The fossil record is in congruence with this hypothesis. Once again it is stressed that the cantharophilous syndrome, as… Expand
Flower visitors to cherimoya, Annona cherimola (Magnoliales: Annonaceae) in Japan
TLDR
The contents and diversities of flower visitor communities appeared to be affected by the surrounding environment and management strategy of the orchards. Expand
Beetle pollination and flowering rhythm of Annona coriacea Mart. (Annonaceae) in Brazilian cerrado: Behavioral features of its principal pollinators
The conservation and sustainable management of Annona coriacea requires knowledge of its floral and reproductive biology, and of its main pollinators and their life cycles. In this work, we analyzedExpand
Perfume-collecting male euglossine bees as pollinators of a basal angiosperm: the case of Unonopsis stipitata (Annonaceae).
TLDR
It is speculated that Unonopsis, which on the basis of molecular age dating is considered a relatively recent genus of the Annonaceae (being 15-30 million years old), has diversified in relation to male euglossine bee pollinators. Expand
The diversity and evolution of pollination systems in Annonaceae
The pollination biology of Annonaceae has received considerable attention, with data now available for > 45% of the genera (or genus-equivalent clades) included in recent molecular phylogeneticExpand
Convergent evolution and adaptive radiation of beetle-pollinated angiosperms
TLDR
The floras of Australia and western North America suggest that mutualistic interactions between beetles and flowers has been a continuous and labile trend in angiosperms with novel interactions evolving through the Tertiary. Expand
Heterodichogamy and nitidulid beetle pollination in Anaxagorea prinoides, an early divergent Annonaceae
TLDR
Heterodichogamy of A. prinoides appears to be a means by which reproductive success is augmented, and attraction of beetle pollinators by “fruit-imitating” floral scent is not restricted to species of Anaxagorea, but occurs in many representatives of the Annonaceae. Expand
Reproductive Biology of Two Sympatric Species of Polyalthia (Annonaceae) in Sri Lanka. I. Pollination by Curculionid Beetles
TLDR
The pollination biology of two sympatric species, Polyalthia coffeoides andPolyalthia korinti (Annonaceae), is described in detail and the extent of competition for pollinators is likely to be lessened due to the abundance and nonspecificity of the beetles. Expand
Pollination Ecology and Breeding System of Xylopia championii (Annonaceae): Curculionid Beetle Pollination, Promoted by Floral Scents and Elevated Floral Temperatures
TLDR
The pollination ecology and breeding system of the Sri Lankan endemic Xylopia championii (Annonaceae) are described in detail and low levels of fruit set in natural conditions suggest that pollinator availability may be a limiting factor. Expand
The evolution of floral biology in basal angiosperms
  • P. K. Endress
  • Biology, Medicine
  • Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2010
TLDR
In basal angiosperms (including ANITA grade, magnoliids, Choranthaceae, Ceratophyllaceae) almost all bisexual flowers are dichogamous, and nearly 100 per cent of those are protogynous (with female function before male function). Expand
Short-distance pollen dispersal in a protogynous Annonaceae tree species from the Brazilian Cerrado
TLDR
Six microsatellite loci were used to assess the mating system and pollen dispersal of A. crassiflora in a savannah remnant in Central Brazil and showed multiple paternity within fruits, indicating some seeds were produced by mating among relatives. Expand

Beetle pollination and flowering rhythm ofAnnona spp. (Annonaceae) in Brazil
TLDR
A staggered flowering period and an alternative attraction of different beetle species seems to be more a device for diminishing competition between the cooccurring Annona spp. Expand
The reproductive biology of primitive angiosperms
TLDR
All flower-visiting insect groups had already existed at the time of early angiosperm differentiation; beetles, flies, thrips, and moths were available as potential pollinators and unspecific interactions are found in the Winteraceae, archaic Magnoliidae. Expand
Some Aspects of Beetle Pollination in the Evolution of Flowering Plants
TLDR
Cantharophily is no longer a sign of primitiveness as it is in the Magnoliidae and to some extent probably also in secondarily polyandrous groups, but a relatively recent adaptation into a still existing ecological niche. Expand

THE STRUCTURE AND FUNCTION OF THE PRIMITIVE ANGIOSPERM FLOWER – A DISCUSSION*
TLDR
Evidence is put forward to show that large, solitary and terminally-borne flowers are not most primitive in the Angiosperms, but rather middle-sized ones, grouped into lateral flower aggregates or inflorescences. Expand
Chromosome numbers and evolution in primitive angiosperms
TLDR
Chromosomal data point to the parallel and reticulate evolutionary patterns of woody Polycarpicae, and remarkable chromosomal similarities with Amentiferae strongly suggest a monophyletic origin of Angiosperms from progenitors with x = 7. Expand

Reproductive structures and phylogenetic significance of extant primitive Angiosperms
TLDR
In the extant primitive Magnoliidae variability occurs on other morphological levels than in the higher advanced Angiosperms, and has to be taken into consideration in evaluations of the systematic relationships of the various groups of theMagnoliidae. Expand
