- Аннотация: The genus Aspidistra comprises about 160 species of herbaceous plants. In previous investigations, different authors suggested that Aspidistra is pollinated by flies, fungus gnats, slugs, amphipods and even collembolans. The vast majority of data was based on the only one species A. elatior and was not confirmed by direct observations. Recent field observations of anthetic plants confirm idea of pollination by flies for two other species of the genus. The present study summarizes direct observations of flowering phenology and pollination of five previously unstudied species of Aspidistra. Flowering biology was studied using visual observations as well as video and photo monitoring. Flowers and captured pollinators were investigated using scanning electron microscopy. As a result, knowledge of flowering biology of Aspidistra has been increased. The absence of heat production and ultraviolet pattern were verified. The present data shows that flowers of Aspidistra can serve as a food resource for animals. The investigated species of Aspidistra are pollinated by dipteran insects: A. formosa, A. marasmioides and A. subrotata are pollinated by fungus gnats, A. multiflora and A. oviflora are pollinated by flies. The occurrence of the fungus-gnat pollination was directly demonstrated for the first time in the genus Aspidistra. The present study confirmed the idea of myiophily in the genus Aspidistra. Apparently, myiophily is common and diverse in Aspidistra. More likely, pollinators are attracted by scent, which is undetectable for humans, but attraction mechanism is still not completely clear.
