A recent investigation of Weinmannia L. (Cunoniaceae) material collected from the Yungas region of La Paz, Bolivia, has uncovered two new species, W. davidsonii A. Fuentes & Z. S. Rogers and W. yungasensis A. Fuentes & Z. S. Rogers, both endemic to the area. Weinmannia davidsonii is similar to W. bangii Rusby but differs most obviously by the tomentose (vs. glabrous) ovary and denser pubescence of the leaves. Weinmannia yungasensis is close to W. dryadifolia Moricand ex Seringe but is distinguished most notably by the leaves that are up to 5-foliolate (vs. up to 3-foliolate), the larger simple leaves (0.9–3 × 0.8–2.5 cm vs. 1–2 × 0.6–1.2 cm), the glabrous (vs. pubescent) stipules, and the lax (vs. congested) longer inflorescences ((2–)3.5–5.5 cm vs. 1–3(–3.5) cm). Both species belong to section Weinmannia L.
