Pedicels 1 per axil, 1–2.3 mm. Flowers: calyx 1.4–2 mm, outer sepals shorter than inner. Capsules subglobose, 1.5–2.2 × 1.3–1.6 mm, longer than calyx. Seeds 2 or 3(4).

Discussion
Varieties 3 (3 in the flora).
Intergradation among the varieties of Lechea pulchella in areas of overlap is common (B. A. Sorrie and A. S. Weakley 2007b). Some authors (K. Barringer 2004; R. L. Wilbur 1966) have not recognized infraspecific taxa.
Selected References
None.
