Krameriaceae (Ratany Family)

Krameria lanceolata (Trailing krameria)
Cressler, Alan
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 branches, up to 2 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.
