Calyx and epicalyx morphology in Indian Hibiscus (Malvaceae) and its taxonomic importance
Nordic Journal of Botany, EarlyView.Hibisceae is one of the largest tribes in Malvaceae, having a diverse floral morphology. The genus Hibiscus shows a wide range of evolutionary patterns in calyx and epicalyx morphology. Genera like Abelmoschus, Azanza, Gossypium, Hibiscus,and Thespesia are separated on the basis of calyx and epicalyx morphology, meaning that the calyx and epicalyx have

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.

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 ...

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.
