Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

Journal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

New Phytologist, EarlyView.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

The power of ionic movements in plants

New Phytologist, EarlyView.
Summary The movement of ion‐driven electrogenic events known as plant action potentials in the Venus flytrap Dionaea muscipula has first been recognized in Darwin's time. Besides electrophysiological techniques making use of current‐ and voltage‐recording electrodes, today an ever‐growing spectrum of tools has become available, that report online ...

Climate adaptation and functional constraints drive pollen evolution in Apiales

New Phytologist, EarlyView.
Summary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

Testing macroevolutionary predictions of the Grant‐Stebbins model in the origin of Aeschynanthus acuminatus

New Phytologist, EarlyView.
Summary The Grant‐Stebbins model predicts that a plant species encountering different pollinators across its range may undergo local adaptation and, subsequently, ecological speciation. We tested whether this could explain the origin of Aeschynanthus acuminatus (Gesneriaceae), a species phylogenetically derived from sunbird specialist ancestors.
