Eriocaulaceae
Syngonanthus

not marked as a favorite taxon Syngonanthus Ruhland. Common name: Yellow Hatpins.

A genus of about 200 species, primarily of tropical America, but some in Africa and Madagascar; ours is the only temperate species.

Glossary (beta!)

ID notes: Syngonanthus flavidulus is distinguished from all other SEUS Eriocaulaceae by its flattened to even somewhat recurved (the leaf tips curving down into the ground at their tips) rosettes of quite narrow leaves, often with a bluish-green color. All of our other Eriocaulaceae have basal rosettes of leaves that are mostly ascending to spreading, and more of a yellowish-green to deep green (or sometimes stramineous) color. In flower, Syngonanthus has a more "chaffy" looking inflorescence, the bracts appearing dry. In contrast, most other US Eriocaulaceae flower heads are at least somewhat fleshy, and most species have white-clavate hairs obscuring most of the floral parts.
