Climbing plants differ from self-supporting plants, such as shrubs and trees, in a range of characteristics, most notable are the mechanical properties of the stem. Liana stems as Pereskia aculeata Mill. (Cactaceae), Pisonia aculeata L. (Nyctaginaceae), Arrabidaea mutabilis Bureau et K.Schum. (Bignoniaceae), Dalechampia stipulacea Müll.Arg. (Euphorbiaceae) and Dicella nucifera Chodat (Malpighiaceae) were collected in Brazilian forest remnants. The objective of this paper is: a) to analyze the comparative stem structure of these species; b) to answer the inquiry whether these species present cambial variants or not and to verify the modes of cambial activities, and c) to contribute with the anatomical identification of the liana species, characterizing... |

The lianas observed in this study, Abuta convexa (Vell.) Diels, Abuta imene (Mart.) Eichler, and Chondrodendron platiphyllum (A. St.-Hil.) Miers, all have successive cambia in their stems. The terminology applied to stem histology in species with successive cambia is as diverse as the interpretations of the origins of this cambial variant. Therefore, this study specifically investigates the origin of successive cambia through a developmental analysis of the above-mentioned species, including an analysis of the terminology used to describe this cambial variation. For the first time, we have identified several developmental stages giving rise to the origins of successive cambia in this family. First, the pericycle originates in 1-3 layers of conjunctive... |
