Discussion
Type. A. cordatum (Juss.) Baillon.
Somewhat similar in vegetative aspects to Conceveiba latifolia. The inflorescence of Aparisthmium is racemose with long-pedicelled 5 flowers. Shape of leaf more acuminate and hairs not stellate. The £ cymules 20-40 flowered disposed in long virgate spikes. In contrast to Aparisthmium, Conceveiba has many stamens and few flowers per cymule.
