About

Damasonium is a genus of six species of flowering plants in the family Alismataceae, commonly known as starfruit and by the older name thrumwort. The genus has a subcosmopolitan but very patchy distribution.

They are aquatic perennial herbaceous plants growing in shallow water or mud beside ponds. The leaves are all basal, floating, or aerial in plants on pond margins. The flowers are hermaphrodite, in one to many whorls, in umbels, racemes or panicles; they have six stamens, and six to nine carpels arranged in a whorl, connate at the base, each with two to many ventral ovules; The styles are terminal. The fruit is a whorl of follicles; the follicles are laterally compressed, radiating in stellate fashion, with a more or less elongated apical beak.
