Taylor and Lepismium cruciforme (Vellozo) Miquel are obligatory epiphytes that occur frequently on tree trunks of remnant forests in Maringa, Paraná state, Brazil. Morphological and anatomical analyses regarding the seedlings were carried out. The seedlings were prepared according to techniques of resin inclusions and histochemical tests. Seedlings were phanerocotyledonar and originated from seeds with operculum. The root was diarch and the hypocotyl presented transition root-stem structure. The cotyledons were sessile, reduced, with homogeneous mesophyll. The epicotyl (phylloclade) presented a lot of parenchyma and reduced vascular cylinder. The 3 studied species showed anatomical characteristics similar to those described for species of Lepismium and Rhipsalis as well as other cacti. 2011 artículo científico 1870-3453 https://www.redalyc.org/articulo.oa?id=42520745012 en http://www.redalyc.org/revista.oa?id=425 Revista Mexicana de Biodiversidad application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Biodiversidad (México) Num.1 Vol.82 |
