''Wimmeria mexicana'' is a large shrub or small tree, often reaching in height, that is common to southeast North America, Oaxaca, Chihuahua, and central to eastern Sonora. It is commonly called Papelío and Algodoncillo.〔Felger, Johnson, & Wilson, p. 133〕 ==Description== The branches and trunk, in diameter, are erect to ascending, making it more tall than wide. Large, flaky, papery, gray plates cover its smooth, white bark. Young twigs, petioles, and flower axils sometimes have short, tiny hairs, but are mostly glabrous. The crown is spread out and sparse. The leaves, exstipulate and 2–6 cm in length, alternate and vary in shape between lanceolate, elliptic, and obovate. Flowers tend to be 7.5–8 mm wide, white to cream colored, bisexual, with 5 petals on 5 sepals, and arranged in axillary cyme. The fruits, 1–1.4 cm across, are papery, one-seeded, three-lobed samaras, similar to species of ''Dodonaea''.〔 ''W. mexicana'' mass flowers around July to October, or often after heavy Autumn rain, attracting a large number of insects, particularly bees and flies. The leaves have serrated edges due to insects.〔
