  • Description

    Latin Diagnosis - Frútices caulibus pilis stellaris pluri-brachiatis; laminis foliorum ovatis vel hastatis in superficie Superioris pilis sim-plicibus adpressis; inflorescentiis paniculatis; bracteis involucellorum 5-6 ciliaris; corollis 1-1.5 cm longis flavidis; fructibus ca. 6 mm diametro rugulosis.

    Species Description - Shrubs 1.5-2 m tall, the stems stellate-pubescent (the hairs widely scattered, multi-armed, more or less appressed, 1 mm diam. or less), and with narrow longitudinal rows of simple recurved hairs. Leaf blades ovate to hastate, to 9 x 7 cm (smaller and narrower upward), cordate to subtruncate in smaller leaves, serrate, acute, palmately 5-9-nerved, somewhat discolorous, the upper surface with abundant appressed simple hairs ca. 0.5 mm long, the lower surface similar but with stellate hairs in addition and rough to the touch; petioles up to 3.5 cm long (reduced upward), densely bearded on adaxial side and with scattered stellate hairs like stem; stipules auriculate or falcate, ca. 4 mm long, reflexed, subglabrous. Flowers axillary but developed into a terminal panicle by branching and leaf reduction; pedicels 1-5 cm long, slender, sparsely stellate-pubescent; involucellar bracts 5-6, ligulate, 8-9 x 2 mm, ciliate (hairs 0.5-1 mm long); calyx 6 mm long, ciliate; petals 1-1.5 cm long, yellow (with a red center?), densely bearded at juncture of claws with androecium; staminal column 3 mm long, the filaments 4-5 mm long; styles exceeding the column by 5-8 mm, free for distal 2 mm. Fruits ca. 6 mm diam., the mericarps (immature) rugulose, obscurely puberulent.

  • Discussion

    Pavonia pseudolaxifolia is similar to P laxifolia but differs in having stems that are stellate pubescent, lacking both long, simple hairs and glandular hairs.

  • Distribution

    At present known only from the Distrito Federal, Brazil.
