Pedicels spreading to ascending, (1–)2–5 mm in flower, to 7 mm in fruit, glandular-villosulous. Flowers: calyx lobes slightly falcate, abaxial slightly shorter than adaxial, 2.6–4 × 0.4–0.7 mm; corolla glabrous, tube 2–3 mm, throat open, yellow or greenish yellow abaxially within, lobes 1 × 1 mm; stamens included; style 0.5–1 mm.

Discussion
As noted by F. W. Pennell (1935), populations of Leucospora multifida often are associated with calcareous substrates; populations also occur on other substrates. They occasionally are reported along railroads and in damp sites in parking lots in urban areas.
