Luehea divaricata

Luehea divaricata, known in Brazil as açoita-cavalo, is a medium to large deciduous to semi-deciduous tree in the Malvaceae family (formerly Tiliaceae), native to the Atlantic Forest, Cerrado, and adjacent regions of Brazil, Paraguay, Argentina, Bolivia, and Uruguay. It typically grows 10 to 25 m tall, with a straight to slightly tortuous trunk 30 to 60 cm in diameter, fissured greyish-brown bark, and a broad, open crown of widely divergent branches (hence "divaricata"). The leaves are alternate, simple, ovate to elliptic, 6 to 14 cm long, with serrate to denticulate margins, an asymmetrical base, three to five prominent palmate-pinnate veins, and a stellate-tomentose lower surface that is paler than the dark green upper face. The flowers are conspicuous, solitary or in few-flowered cymes at branch tips, 3 to 5 cm across, with five spathulate white to pinkish petals, numerous yellow stamens, and a hairy involucel; they appear from late summer to autumn. The fruit is a woody, ellipsoidal, five-valved capsule 2 to 4 cm long, dehiscing to release numerous winged seeds. (POWO; Flora do Brasil)
