  • Discussion

    Illustration. Krapovickas (1982b: pl. 1, fig. IF).

    Pavonia horrida is characterized by very stout spines on the mericarps that are only obscurely and minutely barbed, in common with P. flavispina and P.ionthacarpa. It is distinguished from P. flavispina by its erect habit and from P. ionthacarpa by the characters given in the key.

  • Distribution

    Confined to the state of Santa Catarina, Brazil, in shrubland. The type locality is at 28°29'S, 48°45'W.
