53. Notylia orbicularis subsp. warfordiae Salazar Chávez (1994: 181) .

Type:— MEXICO. Colima, Minatitlán, 1 April 1988, A.R. López-Ferrari, A. Espejo, A. Flores 647 (holotype: AMO 9567!; isotype: UAMIZ 23560!) .

Notes: —Salazar Chávez (1994) described the subspecies based on the sample of López-Ferrari et al. 647, which differed from the type specimen species by having a papillose base of the lip. Therefore, he designated two samples, the one deposited in the AMO herbarium as the holotype and one at UAMIZ as the isotype.
