Abstract. Colpias mollis is a perennial lithophyte that secretes non-volatile oil as a pollinator reward. Its white to yellow flowers bear two narrow pouches lined with glandular oil-secreting trichomes. The pollinating bee, Rediviva albifasciata (Melittidae), collects oil with its forelegs and midlegs by rubbing them against the gland patches within the flower. The presence of specialised hairs on these legs facilitates oil-collection. The strongly congruent geographic distributions of C… Expand

  • 2010
TLDR
Molecular data indicate that the evolution of the Huttonaea-type meranthium was dependent on the prior evolution ofThe oil flower/oil bee relationship and was facilitated by the presence of oil in two separate structures (petal sacs) that were not physically constrained to remain in close proximity.

Inversostyly: a new stylar polymorphism in an oil-secreting plant, Hemimeris racemosa (Scrophulariaceae).
  • A. Pauw
  • Biology, Medicine
  • American journal of botany
  • 2005
TLDR
A new kind of stylar polymorphism, provisionally called inversostyly, is described in Hemimeris racemosa, a common annual herb of the Cape region of South Africa, which has the style and the stamens clustered together in the down position and high levels of autogamous seed set. Expand
Elaiophores in three Neotropical Malpighiaceae species: a comparative study
TLDR
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
Evolution of oil-producing trichomes in Sisyrinchium (Iridaceae): insights from the first comprehensive phylogenetic analysis of the genus.
TLDR
The distribution of oil-flower species across the phylogenetic trees suggests that oil-producing trichomes may have played a key role in the diversification of the genus, a hypothesis that requires future testing. Expand
Oil-producing flowers within the Iridoideae (Iridaceae): evolutionary trends in the flowers of the New World genera.
TLDR
Floral glandular structures and especially trichomal elaiophores evolved multiple times independently in the American tribes of Iridoideae and the distribution pattern of species displaying glandular trichomes across the phylogeny reveals lability in the pollination system and suggests that these structures may have played a significant role in the diversification of the Iridoidae on the American continent. Expand
Elaiophores: their taxonomic distribution, morphology and functions
TLDR
The present review focuses on the morphological and functional aspects of these secretory structures of elaiophores, which mediate a specialized interaction between oil-producing plants and a few species of oil-collecting bees Apidae and Melittidae. Expand
The evolution and loss of oil-offering flowers: new insights from dated phylogenies for angiosperms and bees
  • S. Renner, H. Schaefer
  • Biology, Medicine
  • Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2010
TLDR
Using recent phylogenies, new data on oil-offering Cucurbitaceae, and molecular-dating, it is shown that oil flowers evolved at least 28 times and that floral oil was lost at least 36–40 times in the cause of evolution. Expand
Ancient divergence and contrasting floral biology of the two species of Pachites (Orchidaceae)
TLDR
It is suggested that general floral trait similarity between Pachites species reflects common ancestry, whereas differences in floral morphology, rewards and scent chemistry likely reflect adaptations for different pollination strategies, which evolved during the long time since divergence. Expand
Interaction between oil-collecting bees and seven species of Plantaginaceae
TLDR
The new records of Tapinotaspidini and Centridini species acting as specialized pollinators of Plantaginaceae suggest that there is a geographic variation in the pollinator of the same plant species, and that the evolutionary scenario of the historical relationships between oil-collecting bees and floral oil producing plants is more complex than previously considered. Expand
Playing with extremes: Origins and evolution of exaggerated female forelegs in South African Rediviva bees.
TLDR
The results indicate that foreleg length is an evolutionary highly labile, rapidly evolving trait that might enable Rediviva bees to respond quickly to changing floral resource availability. Expand

The role of nectar and oil in the pollination of Drymonia serrulata (Gesneriaceae) by Epicharis bees (Anthophoridae) in Panama
TLDR
The pollination biology of Drymonia serrulata was studied in central Panama and found drymonia rubra to be pollinated by hummingbirds, a value much higher than has been reported for other bee-pollinated flowers. Expand
An unusual kind of nectary in the oil flowers of Monttea: its structure and function
TLDR
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
Apparent mutualism between Verticordia nitens and V. aurea (Myrtaceae) and their oil-ingesting bee pollinators (Hymenoptera: Colletidae)
TLDR
The ability of E.morrisoni and E. aureophila to remove and utilise pollen, oil and nectar from the flowers, their effectiveness as sole pollinators, and flower colour mimicry by E. morrisoni, together suggest an obligate mutualism between these bees and their Verticordia hosts. Expand
THE ROLE OF RESIN IN ANGIOSPERM POLLINATION: ECOLOGICAL AND CHEMICAL CONSIDERATIONS
TLDR
Scattered observations on the pollination of resin-producing flowers are brought together to discuss the resin-reward syndrome in light of chemical, physical, energetic, and ecological considerations. Expand
Chemical and ethological studies of pollination in the genus Ophrys (Orchidaceae).
TLDR
Ethological field tests indicated chemical mimesis in certain pollinator systems and chemical similarities were found between the volatiles released from Ophrys flowers and the insect glands in a number of pollination systems. Expand
The consequences of specialization for pollination in a rare South African shrub,Ixianthes retzioides (Scrophulariaceae)
TLDR
The discovery of a population in which the predicted specialist pollinator,Rediviva gigas, is present and the presence of this oil-collecting bee resulted in a mean fruit set per plant and a mean seed set increase over a previously studied population lacking the specialist pollinators. Expand
Floral Lipid Chemistry of Byrsonima crassifolia (Malpigheaceae) and a Use of Floral Lipids by Centris Bees (Hymenoptera: Apidae)
TLDR
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.

TLDR

TLDR
Preliminary analysis indicates that the trichomes secrete a complex mixture of lipids, which suggests thatxianthes has lost, at least locally, its specialized pollinator. Expand
