Razisea ericae (Acanthaceae), a New Species from Ecuador and Adjacent Peru

Resumen

Current research by the author on the Acanthaceae treatment for the Flora of Ecuador has resulted in the recognition of a new species from Amazonian Ecuador and Peru. Razisea ericae is de- scribed, illustrated, and compared with its closest relatives in Costa Rica, Panama, and Colombia. Razisea Oersted is a New World genus of six spe- cies, most of which are endemic to Costa Rica. The genus is characterized by a shortly 2-lobed corolla with an entire upper lip and a lower lip that is barely distinct from the corolla tube. The anthers are monothecate and the pollen is spheroidal, bi- porate, and echinulate with the sculpturing between the spines densely granulate (Fig. 2).
