Niche conservatism characterizes the spread of Helianthemum in the Canary Islands
In nearly all cases, each species’ closest relatives occur in a similar niche on a different island

Morphology is most informative in reconstructing early tracheophyte evolution
More so than reproductive or anatomical features, morphology defines evolutionary relationships among early vascular plants.
Temporal patterns of Brassicaceae diversification
Huang et al. propose that whole genome duplication events serve as a constant pump for continuous and high species diversification.
Scaly Tree Ferns Have Slow and Steady Diversification
Did the Cyatheaceae become such a diverse family slowly over time, or in spurts? The largest molecular sampling yet points to gradual accumulation of species.
Molecular phylogenetics and historical biogeography of the tribe Lilieae
Thirty clues to the exceptional diversification of flowering plants
Unmasking cryptic biodiversity in polyploids
A puzzle with uniform flowers
Normally you would expect organs to change across evolutionary time. However, this is not always the case, and some clades can be species-rich, but still have very similar flowers.
Floral nectar tubes in Pelargonium
Aridification as driver of plant evolution
Aridification has been a major force in cycad evolution, says José Said Gutiérrez-Ortega. It helps to explain why cycads were capable to adapt and diversify in the modern habitats, even when they originated in the early evolution of land plants.
Environmental niche divergence among dune shrub sister species
Phylogenetic insights into the evolution of Saxifragales habitat shifts
Secondary phloem diversity and evolution in Bignonieae
This study explores phloem evolution in the species-rich Bignonieae (Bignoniaceae) tribe.
Phylogenetic relationships in Epidendroideae (Orchidaceae)
Freudenstein and Chase analyse seven loci from 310 genera of epidendroids and find increased resolution and support for many groups.
