Early evolutionary history of the seed

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Taxonomic Updates of Thismia pseudomelanomitra (Thismiaceae) Reveal an Old Acquaintance From the Ecuadorian Amazon

open access: yesFeddes Repertorium, Volume 137, Issue 2, June 2026.
ABSTRACT The Amazon Basin is home to the world's greatest terrestrial biodiversity, but many plant groups remain poorly studied. One example is the mycoheterotrophic genus Thismia (Thismiaceae), which is notable for its highly specialized floral morphology and ephemeral life cycles, making it difficult to detect in the field and limiting its ...

Micromorphological Characterization of Astragalus chamaephaca (Fabaceae) With Observations on Pollen Viability

open access: yesFeddes Repertorium, Volume 137, Issue 2, June 2026.
ABSTRACT Astragalus chamaephaca Freyn is a geographically restricted endemic species of Central Anatolia assigned to sect. Macrosemium Bunge. Detailed micromorphological data for this taxon have remained limited. This study provides a comprehensive account of pollen morphology, pollen viability, seed surface ornamentation, and indumentum characters ...

A New Species of Myriopus (Heliotropiaceae) From Brazil

open access: yesFeddes Repertorium, Volume 137, Issue 2, June 2026.
ABSTRACT A new species of Myriopus (Heliotropiaceae), Myriopus chrysocalyx J.I.M. Melo & L.G. Sá, hitherto recorded for the Brazilian Northeastern is described and illustrated. Myriopus chrysocalyx can be readily recognized by its branches strigose to villous, and, mainly, for presenting leaf blade chartaceous to subfleshy, congested inflorescences, a ...

Horses on the Menu: Patterns and Drivers of Free‐Ranging Horse Consumption by Iberian Wolves

open access: yesMammal Review, Volume 56, Issue 2, June 2026.
Free‐ranging mountain ponies can comprise most of the Iberian wolf diet. Through a meta‐analysis of 137 studies, we show that horse consumption is shaped by prey availability, topography and human density, often surpassing wild and domestic ungulates and potentially serving as a buffer for livestock predation.
