Krameria lanceolata

Krameria lanceolata Torr.

Trailing Krameria, Ratany, Crameria, Prairie Sandbur, Trailing Ratany

Krameriaceae (Krameria Family)

Synonym(s): Krameria secundiflora, Krameria spathulata


USDA Native Status: L48 (N)

This is not the sandbur of the Grass Family; however, its burs are just as spiny, though densely covered with white hairs. The flowers and short silky leaves grow on prostrate stems, up to 3 feet long, from a thick woody root. The 5 wine-red sepals may be mistaken for the petals, which are smaller and tinged with green, the upper 3 being united. The flowers are about 1 inch broad. Not conspicuous or abundant.

One of the common names "sandbur" comes from the hard, one-seeded, wooly fruit covered with barbless spines.
