| Abundance | Uncommon and rather local, mainly in regions where Longleaf Pine (Pinus palustris) stands are present. This is a Watch List species. | |
| Habitat | This species occurs in similar habitats as with Lachnocaulon and Eriocaulon species -- damp to wet sandy soils associated with pinelands. It grows in wet spots in pine savannas, ecotones of Carolina bays, scrapes, ditches, margins of pineland pools and ponds. |
| Phenology | Flowers and fruits from May to October. | |
| Identification | Though this species is in a different genus than the other eight species of hatpins/pipeworts/bogbuttons in the family Eriocaulaceae, it nonetheless looks somewhat similar to many others and must be carefully identified owing to it being uncommon and a Watch List species. This species has numerous linear basal leaves, reaching about 3 inches tall and linear, but stiff and somewhat blue-green in color, with the base notably wider and flared. The several flowering scapes are different from the others in that the hairs are glandular and thus should feel somewhat sticky to the touch. Each one ranges to about 8 inches tall, and the single head is somewhat flattened in shape, much wider than high and disk-shaped, about 5.5-8 mm (about 1/4-inch) long. The head is typically somewhat cream-colored, to very pale yellow, but the common name is a misnomer, as the flowers are nowhere near yellow in color. | |
