Nectary structure of Ornithidium sophronitis Rchb.F. (Orchidaceae: Maxillariinae)

open access: yesActa Agrobotanica, 2012
Most orchids do not produce floral food-rewards. Instead, they attract pollinators by mimicry or deceit. When present, the most common floral food-reward is nectar.

Comparative Nectary Morphology across Cleomaceae (Brassicales)

open access: yesPlants, 2023
Floral nectaries have evolved multiple times and rapidly diversified with the adaptive radiation of animal pollinators. As such, floral nectaries exhibit extraordinary variation in location, size, shape, and secretory mechanism. Despite the intricate ties to pollinator interactions, floral nectaries are often overlooked in morphological and ...

Morphology, anatomy and ultrastructure of yarrow (Achillea millefolium L.) floral nectaries

open access: yesActa Agrobotanica, 2012
The studies focused on the morphological and anatomical features as well as those related to the ultrastructure of nectary cells Achillea millefolium Asteraceae family. The nectary presence was confirmed only in the disk flowers at the pistil style base.

Morphological Diversity and Relationships in the A-Genome Cottons, Gossypium arboreum and G. herbaceum [PDF]

open access: yes, 1994
The Asiatic or A-genome cottons, Gossypium arboreum L. and G. herbaceum L., are potentially important genetic resources for cotton breeding programs. The National Plant Germplasm System (NPGS) contains approximately 400 accessions of these species, but ...

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

open access: yesNordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...
