A importância da anatomia na descrição dos subgêneros de Passiflora L. (PASSIFLORACEAE) através de espécies nativas em Juiz de Fora, MG

Abstract

The Passifloraceae family has a mainly Neotropical distribution. They are lianas with a morphological variety and stand out for their showy flowers and fruits. Passiflora L. is the best-known genus of the family, and presents a complex taxonomy, undergoing several taxonomic modifications. Currently, Passiflora is divided into six subgenera, namely: P. subg. Astrophea (DC.) Mast., P. subg. Deidamioides (Harms) Killip, P. subg. Decaloba (DC.) Rchb., P. subg. Passiflora L., P. subg. Tetrapathea (DC.) P. S. Green and P. subg. Tryphostemmatoides (Harms) Killip. In this study, seven species were collected in the region of Juiz de Fora, MG: Passiflora alata Curtis; Passiflora amethystina J.C.Mikan; Passiflora edulis Sims; Passiflora sidifolia M.Roem; Passiflora speciosa Gardner; Passiflora tenuifila Killip of the subgenus Passiflora and Passiflora capsularis L. of the subgenus Decaloba. The species P. tenuifila stands out because it is a new occurrence recorded for the municipality of Juiz de Fora. In these species, the anatomy of the leaf blade, petiole and glands were performed, in addition, Scanning Electron Microscopy was performed on the glands of the petioles. The characteristics visualized in the results are of utmost importance to corroborate the works of the genus, aiding in the description of the species and consequently in the taxonomy of the group.
