RZEDOWSKI, Jerzy  e  CALDERON DE RZEDOWSKI, Graciela. Two new species of Perymenium (Compositae-Heliantheae) from central Mexico. Act. Bot. Mex [online]. 2011, n.97, pp.57-63. ISSN 2448-7589.

Perymenium ibarrarum and P. moctezumae are described as new and illustrated. The first one resembles and is possibly related to P. hintonii McVaugh; the second seems to be related to P. tamaulipense B. L. Turner and to P. sotoarenasii Rzed. & Calderón. Both are only known from the type collections.
