Fruit evolution in Hydrophyllaceae

open access: yesAmerican Journal of Botany, Volume 108, Issue 6, Page 925-945, June 2021., 2021
Premise Fruit type and morphology are tightly connected with angiosperm diversification. In Boraginales, the first‐branching families, including Hydrophyllaceae, have one‐ to many‐seeded capsules, whereas most of the remaining families have four‐seeded indehiscent fruits. This fact argues for many‐seeded capsules as the ancestral condition.

Virus‐induced gene silencing as a tool for functional studies in Cleome violacea

open access: yesApplications in Plant Sciences, Volume 9, Issue 5, May 2021., 2021
Premise Cleomaceae is emerging as a promising family to investigate a wide range of phenomena, such as C4 photosynthesis and floral diversity. However, functional techniques are lacking for elucidating this diversity. Herein, we establish virus‐induced gene silencing (VIGS) as a method of generating functional data for Cleome violacea, bolstering ...

Anatomy and ultrastructure of floral nectaries of Asphodelus aestivus Brot. (Asphodelaceae)

open access: yesActa Agrobotanica, 2012
The structure of septal nectaries in Asphodelus aestivus flowers was investigated by using light microscopy (LM), scanning electron microscopy (SEM) and transmission electron microscopy (EM).

The flower morphology in three Convallariaceae species with various attractive traits

open access: yesActa Agrobotanica, 2017
The general morphology and micromorphology of the flower in Polygonatum multiflorum, Maianthemum bifolium, and Convallaria majalis were studied using light microscopy methods. Among the studied species, P. multiflorum and C.

The location of nectaries and nectar secretion in the flowers of Allium giganteum Regel

open access: yesActa Agrobotanica, 2012
In the flowers of Allium there are found septal nectaries; in particular species, their outlet can be located in different parts of the ovary. The inflorescences of these plants are a rich source of nectar for insects.

Ecology of flowers and morphology of pollen grains of selected Narcissus varieties (Narcissus pseudonarcissus x Narcissus poëticus)

open access: yesActa Agrobotanica, 2012
The investigations carried out in the years 2004-2005 covered five varieties of Narcissus (Narcissus pseudonarcissus L. x Narcissus poëticus L.): 'Fire Bird', 'Hardy', 'Ivory Yellow', 'Pomona' and 'The Sun'. Longevity of a flower and the flowering period

Phylogeny of subtribe Gonolobinae (Apocynaceae‐Asclepiadoideae) based on molecular and morphological data with a revised generic classification

open access: yesTAXON, Volume 75, Issue 2, April 2026.
Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...

Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen‐rewarding Caribbean bloodwort

open access: yesAmerican Journal of Botany, Volume 113, Issue 2, February 2026.
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Multiple signalling increases both prey response and diversity in a carnivorous pitcher plant

open access: yesFunctional Ecology, Volume 40, Issue 2, Page 451-462, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Organisms across the tree of life use multiple signals such as colour, movement sound, and many types of chemical signals to convey seemingly the same information. These signals are potentially costly, yet the repeated evolution of multiple signalling across systems ...
