Eriocaulon

Eriocaulon is a genus of small, tufted herbs belonging to the family Eriocaulaceae. These plants are typically found in aquatic and marshy environments, primarily in tropical and subtropical regions, with some species extending into temperate areas like Japan and North America. They are characterized by grass-like leaves and inconspicuous flowers that grow in dense heads, sometimes resembling those of a sunflower. The flowers can be unisexual or bisexual. The genus name itself, Eriocaulon, comes from Greek words meaning "woolly stalk".123
