Discussion:Illustration. Krapovickas (1982b: fig. IB, pl. 2).

Pavonia ionthacarpa is characterized by the spines of the mericarps being only obscurely and minutely barbed, in common with those of P. flavispina and P. horrida. It is distinguished from P flavispina by its erect habit and from P. horrida by the characters given in the key.
