PLANTS, PEOPLE, PLANET, EarlyView.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.

PLANTS, PEOPLE, PLANET, EarlyView.Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

PLANTS, PEOPLE, PLANET, EarlyView.Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

1170. Allium kollmannianum Brullo, Pavone & Salmeri
Curtis's Botanical Magazine, EarlyView.Summary Allium kollmannianum is a small, late‐spring to early‐summer blooming Allium, endemic to the Negev Desert in south Israel, and previously thought to be extremely rare and critically endangered. Here we expand new information regarding its distribution and habitat in the Negev Desert, and a new estimation of its threat level, considering the new

Corona development and floral nectaries of Asclepiadeae (Asclepiadoideae, Apocynaceae) [PDF]
Acta Botanica Brasilica, 2017 ABSTRACT Flowers of Asclepiadoideae are notable for possessing numerous nectaries and elaborate coronas, where nectar can accumulate but is not necessarily produced. Given the complexity and importance of these structures for reproduction, this study aimed to analyze the ontogeny of the corona, the structure and position of nectaries and the ...

The structure of the spur nectary in Dendrobium finisterrae Schltr. (Dendrobiinae, Orchidaceae)
Acta Agrobotanica, 2012 To date, the structure of the nectary spur of Dendrobium finisterrae has not been studied in detail, and the present paper compares the structural organization of the floral nectary in this species with the spurs of other taxa.
