“…However, in this study, it was observed that the arrangement and shape of the areola were different and unique for each taxon. These characters were important to differentiate taxa, corroborating to the work from Oliveira et al (2011), where these characters were used to differentiate Myrtaceae species. The free end veins (FEVs) or free venules are commonly composed by two-three branches.…”

The study and characterization of leaf venation plays a key role in the recognition of taxonomic groups that have been identified mainly based on reproductive traits. This study aimed at characterizing the pattern of leaf venation of Rubiaceae, recognizing individual characters among the taxa of this group and testing the use of leaf architecture as a taxonomic tool capable of providing vegetative and diagnostically characteristics between species. Leaves of 14 species distributed in eight genera from Rubiaceae were diaphanized and classified. The study area is located in Área de Proteção Ambiental Serra Branca/Raso da Catarina, Bahia State, Brazil. The characterization of secondary veins, including type, spacing and number of pairs, third veining patterns, fourth and fifth order, and the conformation of the areola were useful to delimit taxa when used together, providing subsidies to more comprehensive studies.

“…Our results showed that the position of vascular bundles on petioles is useful to the group and distinguish species of Banisteriopsis, corroborating the data of Metcalfe & Chalk (1950) and Araújo et al (2010) for Malpighiaceae. Characters related to vascularization patterns of petioles have been widely used to improve the taxonomy of different families of flowering plants, such as Melastomataceae (Reis et al 2004), Myrtaceae (Oliveira et al 2011), Rubiaceae (Moraes et al 2011), Sapotaceae (Almeida Jr. et al 2013) and Leguminosae (Francino 2006;Coutinho et al 2013). Accessory bundles occurred in 40 of 42 species of Banisteriopsis, varying in the number of bundles, sometimes in specimes from the same species.…”

Taxonomic relevance of leaf anatomy in Banisteriopsis C.B. Rob. (Malpighiaceae)

2020

We describe the leaf anatomy of 42 of the 60 species of the genus Banisteriopsis, one of the largest and most diverse genera of Malpighiaceae in the Cerrado domain. Our aim was to identify anatomical leaf characters useful for the taxonomy and systematics of this morphological diverse genus. Expanded leaves from herbarium specimens were rehydrated and processed according to usual anatomical methods for analysis under light microscopy. All characters were compared using the Unweighted Pair Group Method with Arithmetic Mean algorithm and expressed in dendrograms. The most useful leaf anatomical characters were petiole contour, presence/absence of vascular bundles in the petiole, the position of the vascular bundles in the petiole, shape of the midrib, presence/absence of sheath extension, mesophyll type, and both the presence/absence and shape of leaf glands. Our study indicates that the morphological groups proposed in the literature for Banisteriopsis are natural groups.

“…While in S. sordida and S. warmingii it is "V" shaped, in S. pauciflora it is arc shaped. Some of these features have been identified in other groups, where they were proved to be useful for taxonomy, as in Campomanesia -Myrtaceae (Oliveira et al 2011), Rubiaceae (Martínez-Cabrera 2009) and in Melastomataceae (Reis et al 2004) in which the distinctive characters were, among others, the vascular system pattern in the petiole.…”

Comparative leaf anatomy of neotropical Stylogyne species (Myrsinoideae - Primulaceae)

et al. 2013

Anatomical studies were performed here in order to provide diagnostic characteristics to differentiate the species Stylogyne depauperata, S. pauciflora, S. sordida and S. warmingii. Fully expanded leaves were processed by the usual techniques of optical microscopy and scanning electron microscopy. Traits common to all species were observed, such as dorsiventral mesophyll, unistratified epidermis, anisocytic stomata, druses and secretory cavities distributed throughout the mesophyll. Cuticular ornamentation, configuration of the vascular system in the petiole and shape of the secretory cavities provide diagnostic characteristics. Variance analysis proved that these characters are potentially efficient to differentiate these species.
