Discusión taxonómica
Citation of this species from Nayarit by Mickel and Beitel (1988) is the result of misidentification of a specimen of D. lonchophyllum. Several other specimens cited as D. cristatum from Oaxaca (Mickel & Beitel, 1988), from the Sierra de Miahuatlán, are probably also D. lonchophyllum (Mickel 5026, NY, UC, 6010, NY, juvenile, 6019, NY), but both species apparently occur in that area. Two of the four specimens cited by Palacios Rios (1992) as D. cristatum are D. lonchophyllum: Conzatti 802, MEXU; Palacios Rios & Hernández M. 610, XAL; we have not seen the other two (Castillo & Medina 4288, XAL, and Nee 22582, F, XAL), but their identity needs verification).
