Leaves are extraordinarily variable in form, longevity, venation architecture, and capacity for
photosynthetic gas exchange. Much of this diversity is linked with water transport capacity …

The Cambrian diversification of animals was long thought to have begun with an explosive
phase at the start of the Tommotian Age. Recent stratigraphic discoveries, however, suggest …

Leaf veins are almost ubiquitous across the range of terrestrial plant diversity, yet their
influence on leaf photosynthetic performance remains uncertain. We show here that specific …

Angiosperm leaves manifest a remarkable diversity of shapes that range from
developmental sequences within a shoot and within crown response to microenvironment to …

The plant kingdom exhibits diverse bodyplans, from single-celled algae to complex
multicellular land plants, but it is unclear how this phenotypic disparity was achieved. Here …

The veins that irrigate leaves during photosynthesis are demonstrated to be strikingly more
abundant in flowering plants than in any other vascular plant lineage. Angiosperm vein …

More than 40 000 km3 year–1 of water flows through the intricate hydraulic pathways inside
leaves. This water not only sustains terrestrial productivity, but also constitutes nearly 70% of …

Land plants exhibit a degree of homeostasis in leaf water content to protect against damage
to photosynthetic and xylem tissues, and to maintain an efficient allocation of resources. This …

Simpson's “early burst” model of adaptive radiation was intended to explain the early
proliferation of morphological and functional variation in diversifying clades. Yet, despite …
