  • Type

    Type. Brazil. Minas Gerais: Grao Mogol, 8 Jul 1975, Barroso s.n. (holotype, CTES; isotypes, MBM-n.v., P-n.v., RB-n.v.).

  • Description

    Species Description - Shrubs 2 m tall, the stems densely stellate-puberulent and viscid. Leaf blades broadly ovate, 2.5-9 x 2.5-7 cm, cordate, denticulate to subentire, acute or acuminate, discolorous, palmately 7-nerved, the upper surface stellate- and glandular-pubescent, the lower surface predominantly stellate-pubescent, whitish; petioles 1.5-8 cm long; stipules 4-10 mm long, subulate. Flowers solitary in the leaf axils, the pedicels 1-6 cm long; involucellar bracts 4(-6), broadly ovate, 20-25 x 10-15 mm (rarely only 5 mm wide, e.g., Esteves & Kameyama 2503), viscid; calyx 1.5 cm long, viscid; corolla 2-3 cm long, externally stellate-pubescent, greenish yellow with reddish veins; androecium included, the styles slightly exserted. Fruits glabrous, ca. 6 mm diam.; mericarps 10 mm high, with a stout apical spine.

  • Discussion

    Pavonia grazielae is characterized by its few (4-6), broadly ovate, viscid involucellar bracts.

    A collection by Pirani et al. (Grão Mogol, Vale do Rio Itacambiruçu, SPF-39645, CTES) may represent this species but is anomalous in having usually 6 bracts that are only 3-6 mm wide. However, it comes from within the range of the species and is tentatively included with it.

  • Distribution

    Confined to the state of Minas Gerais, Brazil, growing in cerrado vegetation at elevations of 700-1300 m. The type locality is at 16°35'S. 42°53'W.
