Evolutionary Signal of Leaflet Anatomy in the Zamiaceae [PDF]
Premise of research: The morphology of leaves is shaped by both historical and current selection acting on constrained developmental systems. For this reason, the phylogenetic signal of these characters is usually overlooked. Methodology: We investigate morphology of the leaflets of all genera of the Zamiaceae using multiple microscopical techniques to

Diel net CO<sub>2</sub> exchange of carnivorous Pinguicula is consistent with low-level CAM photosynthesis. [PDF]
In carnivorous butterworts (Pinguicula), CO2 uptake occurs primarily in the light via C3 photosynthesis, yet low‐level CAM photosynthesis, including net CO2 dark fixation, significantly improves the carbon balance of plants, especially under water‐deficit conditions.

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration. [PDF]
Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

What is Ceratozamia mexicana (Zamiaceae)? [PDF]
Explorations in central Veracruz on the Transvolcanic Mexican Belt and regions explored by 19th century botanists we found various populations of Ceratozamia whose taxonomic status is not yet completely clear. Especially two populations of C.
