A New Locality of Pleopeltis xsordidula (Maxon & Weath.) Mickel & Beitel in the State of Puebla, Mexico.A New Locality of Pleopeltis xsordidula (Maxon & Weath.) Mickel & Beitel in the State of Puebla, Mexico.--During recent field work in the State of Puebla, Mexico, we found a specimen of Pleopeltis xsordidula (Maxon & Weath.) Mickel & Beitel (Fig. 1), which was previously known from Veracruz. An additional collection from Tlaxco, Tlaxcala was cited by Arreguin et al. (Polibotanica 17:39-43. 2004), but we could not see the specimen to verify it. This hybrid is believed to have originated from a cross involving P. astrolepis (Liebm.) E. Fourn. and P. fallax (Schltdl. & Cham.) Mickel & Beitel. Our finding of this hybrid was made at Municipio Cuetzalan, on the way to the cave of Atepolihui (L. Pacheco 3816 & A. Sanchez Morales, UAMIZ). The plant was growing in montane rain forest at 850 m as an epiphyte epiphyte (ĕp`əfīt') or air plant, any plant that does not normally root in the soil but grows upon another living plant while remaining independent of it except for support (thus differing from a parasite). . Only one plant was found with old sporangia sporangia see spherules. and few white spores. All morphological characters agreed with the isotype i·so·type n. An antigenic marker that occurs in all members of a subclass of an immunoglobulin class. i at US. Although the putative parents are P. astrolepis and P. fallax, only P. fallax was found at the same locality as the hybrid.--LETICIA PACHECO, ANDRES SANCHEZ MORALES & CARMEN DE LA PAZ PEREZ OLVERA, Universidad Autonoma Metropolitana-Iztapalapa, Depto. de Biologia, Area de Botanica Estructural y Sistematica Vegetal, Apdo.
