There's not a lot on a butterfly, if you ignore the wings. That's why some plants keen on pollination target them.

Herkogamy and dichogamy in style dimorphic flowers of Narcissus broussonetii (Amaryllidaceae)
Across the plant kingdom, there is an extraordinary diversity of flower forms, many of which are related to variation in the morphology and arrangement of reproductive organs. To prevent self-pollination, plants have...

Floral nectar tubes in Pelargonium
Co-evolutionary matches between lengths of floral nectar tubes and pollinator proboscises is associated with speciation in several lineages, including Pelargonium (Geraniaceae), a genus renowned for morphological...

New insights into the evolution of the florally diverse Detarioid legumes
The Brazilian tree Goniorrhachis marginata is the only species of its genus in the bean family (Leguminosae) with striking flowers consisting of a long floral tube and regular corolla redolent of the rose family...
Tinkering with transcription factor networks for developmental robustness of Ranunculales flowers
Species within the Ranunculales bear flowers of formidable variation; for example, one can find novel floral organs and loss of floral organs, zygomorphic and radially symmetric flowers, and variation in floral organ...
The significance of developmental robustness for species diversity
Why some taxa are more species-rich than others still represents a major conundrum in biology. Ecological opportunities and evolutionary innovations are considered main factors that drive biodiversity, but are sometimes...
Phyllotaxis in arabidopsis cuc2 cuc3 double mutants
In the cuc2 cuc3 double mutant of Arabidopsis thaliana the regular spiral Fibonacci phyllotaxis is disrupted and flower pedicels are fused to the inflorescence stem in the mature shoot regions. Burian et al. investigate...
Phenotype instability modification by auxin inhibitors and 2,4-D
Based on the phenotypic instability observed in Barley, definite trends in the development of ectopic flower structures can be outlined.
Temperature and reproductive success in arabidopsis
Seed yield and dormancy status are key components of species fitness that are influenced by the maternal environment. Huang et al. grow the Arabidopsis thaliana ecotype Burren (Bur), which is adapted to a cool, damp...
Flower Development: a Special Issue of Annals of Botany
In the early 1990s, genetic studies performed in parallel in the distantly related eudicot species Arabidopsis thaliana and Antirrhinum majus led to the unifying and now widely known “ABC model” for the definition of...

Flowering around the Med
The latest in a series of two-yearly workshops on Molecular Mechanisms Controlling Flower Development was held this June on the Giens Peninsula of the French Cote d’Azur. This workshop, which was generously supported by...
Epigenetic floral variant of clonal oil palm (Review)
The mantled somaclonal variation of oil palm (Elaeis guineensis) hampers oil production as the supernumerary female organs are either sterile or produce fruits with poor oil yields. Jaligot et al. provide an overview of...
Number and position of floral organs in Arabidopsis
Information regarding polymorphism of floral structure is important for understanding the genetic and evolutionary mechanisms of flower development. Penin and Logacheva conduct a wide survey of the variations in number...
