Ranalisma rostrata is a critically endangered marsh plant species in the Alismataceae family. It is one of two species in the genus Ranalisma and was first described by Stapf in 1900. The species is listed as a national level I key protected plant in China, and its population has increased due to breeding programs. Research indicates that volatile compounds and water extracts from Isodon globosa and Pogostemon praetermissum inhibit the seed germination of R. rostrata and affect root development, though they do not impact bud formation.

Description

Ranalisma rostrata is found in the Oriental (Indomalaya) region, including China Southeast, Hainan, Malaya, and Vietnam. As a member of the Alismataceae family, it is a rare and protected species. Breeding programs in China have contributed to a recovery in its population. Studies have shown that extracts from certain plant species can significantly reduce seed germination and alter root growth in R. rostrata, but have no effect on bud development.
