Leaves 3-foliolate; stipules curved, slightly reflexed to spreading, subulate, 1–2 mm, 1/2 as long as petioles or shorter, minutely stipitate-glandular to glabrate; petiole 4–10 mm, minutely stipitate-glandular to glabrate; leaflets linear to linear-lanceolate, minutely stipitate-glandular, apex spinose, terminal 3–10 × 1 mm, laterals 2–9 × 1 mm, slightly shorter than but as wide as terminal, sometimes caducous. Pedicels 8–20 mm, slender, stipitate-glandular.

Fagonia longipes is restricted to the Mojave and Sonoran deserts, where it appears to have a more northern distribution than F. laevis. See 1. F. laevis for a discussion of the differences between these species.
