Authority: Fryxell, Paul A. 1999. Cavanilles (Malvaceae). Fl. Neotrop. Monogr. 76: 1-284. (Published by NYBG Press)
Description:Latin Diagnosis - Frútices, caulibus minute glanduloso-pubescentibus; laminis foliorum ovatis vel triangularibus subtiliter puberu-lentibus, stipulis reflexis; floribus solitariis in axillis foliorum; bracteis involucellorum 13-16 ciliaris; corollis 2.5-3 cm longis flavidis; fructibus ca. 9 mm diametro glabris rugulosis.

Species Description - Shrubs 1.5 m tall, the stems minutely and finely glandular-puberulent. Leaf blades ovate to hastate-triangular, basally truncate, serrate, acute, palmately 5-7-nerved, 4-8 x 3-5 cm, nearly concolorous, finely puberulent above and beneath and with widely scattered larger stellate spicules beneath; petioles 1-3 cm long, glandular-puberulent; stipules lanceolate to falcate, reflexed, 5-6 mm long. Flowers solitary in the leaf axils, the pedicels 1-2.5 cm long, finely puberulent like stem and in addition with pilose hairs 1-1.5 mm long distally; involucellar bracts (11-) 13-16, linear, 15-20 mm long, copiously ciliate, with underlying glandular puberulence; calyx 1 cm long, ciliate and with underlying glandular puberulence; corolla 2.5-3 cm long, yellow; androecium included in corolla, the column ca. half the length of the petals; styles emergent from the column, the stigmas subequal to the petals. Fruits ca. 9 mm diam., glabrous; mericarps 5 mm tall, rugulose.

Discussion:The specific epithet is chosen to honor the cocollector of the type, Carmen L. Cristóbal of Corrientes, Argentina, knowledgeable specialist with the Sterculiaceae. As is indicated by its position in the key, Pavonia cristobaliae is evidently a vicariad of P. subhastata, the two species sharing many characters, yet being clearly distinct, both geographically and morphologically.
