Moehringia lateriflora

About

Moehringia lateriflora, commonly known as the blunt-leaf sandwort, is a plant species in the Alsinoideae subfamily of the carnation family, Caryophyllaceae. It is a small perennial herb that grows in a variety of habitats and is native to much of the Northern Hemisphere, including northern and eastern Europe, Asia, the northern United States, and most of Canada. As with other members of its genus, M. lateriflora has spongy appendages on its seeds, called elaiosomes, that attract ants, which help with its dispersal. It is also a host to several fungal pathogens, including an undescribed species of anther smut spread from flower to flower by pollinating insects.
