The developmental basis of floral nectary diversity and evolution [PDF]

open access: yesNew Phytologist
Summary Nectar is a central bridge between angiosperms and animal mutualists. It is produced by specialized structures termed nectaries, which can be found on different plant organs. Consumption of floral nectar by pollinators and the subsequent transfer of pollen contribute to the reproductive success of both angiosperms and their pollinators.

From flower to fruit: The origin of the trilocular ovary and fruit development in Phragmipedium longifolium (Warsz. & Rchb.f.) Rolfe (Orchidaceae: Cypripedioideae). [PDF]

open access: yesPlant Biol (Stuttg)
Phragmipedium longifolium has a trilocular ovary with a post‐genital septum, and during fruit development, lignification plays a crucial role in facilitating dehiscence and seed dispersal. Abstract While carpels in Orchidaceae are predominantly unilocular, trilocular carpels can also occur, mainly in branches separated during the early diversification ...

Nichima gen. nov. (Alismataceae) based on reproductive structures from the Oligocene‐Miocene of Mexico

open access: yesAmerican Journal of Botany, Volume 110, Issue 10, October 2023., 2023
Abstract Premise Alismataceae, a sub‐cosmopolitan family with ca. 17 genera and 113 species, is a large group of aquatic plants. Compression/impressions and bioinclusions of reproductive parts in amber support the documentation of the lineage in low‐latitude North America. In Mexico, fossil aquatic plants have been infrequently documented.

Floral attraction and flower visitors of a subcanopy, tropical rainforest tree, Fontainea picrosperma

open access: yesEcology and Evolution, Volume 11, Issue 15, Page 10468-10482, August 2021., 2021
Pollinators beneath the rainforest canopy occupy a unique microclimate that is markedly different from the canopy environment that receives more light energy. We studied the floral attractants and floral visitors of a dioecious, subcanopy rainforest tree, Fontainea picrosperma (Euphorbiaceae), in northern Australia.
