Effect of climate, anther morphology and pollination syndrome on pollen availability in Penstemon
Journal of Pollination Ecology, 2023 Traditionally, pollen presentation is thought to be a function of pollinator type and visitation frequency. However, despite the repeated observation that pollen presentation is influenced by flower morphology and abiotic factors, these aspects have been

Botanical Sciences, 2020 Background: Although pollen morphology has always been an important tool in plant systematics, the possibility of distinguishing between related taxa is still debated. A difficult case is the cycads, where their morphology and small size is very similar.
