Floral chemistry reveals the basis of an orchid pollinator shift
A greater concentration of a compound present throughout the species allowed one morph to attract bee pollinators.

The flower that targets its nectar to the specific needs of its pollinators
Impatiens offers its pollinators the best nectar, but the best nectar for one pollinator isn't always the best for another.
For the Pineapple Lily, attraction is a matter of chemistry
Eucomis regia, the pineapple lily, doesn't attract insects or birds to pollinate it. So how does it reproduce?
The rewards of chasing nectar
We know that flowers entice pollinators with nectar, but how much and what causes a flower to produce as much or as little nectar as it does. In this guest post, Amy Parachnowitsch, Jessamyn Manson and Nina Sletvold...

Petal spur development in Centranthus
When concealed by petal spurs, nectar typically is restricted to flower-visiting animals possessing a sufficient tongue length to acquire it, and thus such spurs have evolutionary significance, often leading to...

Sugar versus Auxin: which is dominant?
Of the plethora of aspects of plant growth and development that the hormone (OK, plant growth regulator…) auxin is implicated in/involved with (e.g. embryo development, leaf formation, phototropism, gravitropism, fruit...

Nectary evolution in Disa orchids
Independent nectary evolution of orchid genus Disa has involved both repeated recapitulation of secretory epidermis, and innovation of stomatal nectaries.
Non-leaf photosynthesis
Photosynthetic activity of green nectaries can explain a significant part, if not all, of the sugar secreted in nectar.
Highlight on diversity, ecology and evolution of extrafloral nectaries
Plants in over 100 families bear extrafloral nectaries (EFNs), which secrete a carbohydrate-rich food that attracts ants and other arthropods. By fostering ecologically important protective mutualisms, EFNs play a...
