Flowering biology and structure of floral nectaries in Galanthus nivalis L.

open access: yesActa Societatis Botanicorum Poloniae, 2016
In Poland Galanthus nivalis L. is partially protected. The flowers of this species are one of the first sources of nectar and pollen for insects from February to April. The aim of this study was to present the flowering biology as well as the topography,

Lantana delicata (Verbenaceae), a New Species From Brazil, and Additional Updates Within the Genus

open access: yesFeddes Repertorium, Volume 137, Issue 3, September 2026.
ABSTRACT In this study, we present some novelties in Lantana, a taxonomically complex genus of Verbenaceae. These include (1) the description of L. delicata, a new species from Brazil; (2) the lectotypification of the name L. magnibracteata; and (3) the recognition of L. fucata f. albiflora, previously regarded as a synonym of L.

Genome‐Wide Identification of YABBY Genes in Medicago truncatula Reveals a Role for MtYAB3 in Petal Lateral Expansion

open access: yesLegume Science, Volume 8, Issue 3, September 2026.
ABSTRACT YABBY transcription factors are plant‐specific regulators of lateral organ development, yet their functions in legume flower morphogenesis remain poorly understood. Here, we identified seven YABBY genes in the Medicago truncatula genome and assigned them to five conserved subfamilies.

Floral ontogeny, petal diversity and nectary uniformity in Bruniaceae [PDF]

open access: yesBotanical Journal of the Linnean Society, 2006
Bruniaceae are a small family subendemic to the Cape Floristic Region. Flowers are actinomorphic, choripetalous, pentamerous and tetracyclic. The petals show diverse adaxial swellings, which have been quoted as an example of diplophylly. Developmental studies confirm the true choripetaly of the flowers, thus pointing to an affinity to the Apiales within ...

Integrative analysis of transcriptome and proteome revealed nectary and nectar traits in the plant-pollinator interaction of Nitraria tangutorum Bobrov

open access: yesBMC Plant Biology, 2021
Background Nitraria tangutorum is an important desert shrub that shows resistance to drought, salt and wind erosion stresses. It is a central ecological species in its area. Here, we have studied how N.

Sinningia pampeana sp. nov. (Gesneriaceae) from the Pampa's rocky outcrops in southern Brazil and Uruguay

open access: yesNordic Journal of Botany, Volume 2026, Issue 9, September 2026.
Sinningia pampeana is a new rupicolous species from the rocky outcrops of the Pampa biome in southern Brazil and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii.

Movers and shakers: Bumble bee foraging behavior shapes the dispersal of microbes among and within flowers

open access: yesEcosphere, 2019
Dispersal is central to the ecology and evolution of spatially structured communities. While flower microbial communities are spatially structured among floral organs, how dispersal vectors distribute microbes among floral organs is unknown.

The structure of nectaries in the genus Strombocactus (Cactaceae)

open access: yesBotan‪ical Sciences, 2019
Background: Floral nectar is offered by the plant to its pollinators to promote cross-fertilization. Questions: Are floral nectaries morpho-anatomically similar among the taxa of Strombocactus? What sugars do nectaries offer their pollinators? Studied

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1407-1418, September 2026.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.
