Two scapiform species of Acourtia are described as new, both growing in soils derived from marine sedimentary rocks in the state of Queretaro. Acourtia mectezumae sp. n. seems to be related to A. scapose (Blake) Turner and A. umbratilis (Rob. & Greenm.) Turner. Acourtia elizabethiae sp. n. shows more resemblance to A. discolor Rzedowski and to A. nudicaulis (A. Gray) Turner.
