“…In the analyzed species, the presence of vascularization in leaf and calyx glands was detected, similar to what was observed by Possobom et al (2010;2015) in Diplopterys pubipetala and Mamede (1993) in eight species of Camarea. According to Elias et al (1975), nectaries that are vascularized are highly specialized and characteristically remain active for only for a short period of time, usually only a few weeks when the leaves are expanding.…”

Banisteriopsis is considered one of the largest genera of Malpighiaceae with 58 species, of which 47 occur in Brazil. The typical calyx and leaf glands of Banisteriopsis are considered relevant to the adaptive success of Malpighiaceae. Comparative studies of anatomical and histochemical characteristics may reveal similarities and assist in the interpretation of the functions performed by such glands. The present study aimed to describe the anatomy of the calyx and leaf glands of 38 species of Banisteriopsis that occur in Brazil, and to analyze these structures histochemically in B. campestris, B. laevifolia and B malifolia, using standard methods. Calyx glands differ from leaf glands by possessing an irregular surface that is covered by a thick cuticle that is released from the epidermis by the accumulation of secretion; the glands are similar in all the other anatomical characteristics. Both types of glands produce secretions composed of a mixture of protein granules, lipids and polysaccharides. These findings reinforce the hypothesis that foliar glands have given rise to calyx glands in response to interactions with pollinators.

“…This approach makes it possible to correctly identify fragmented or sterile plant specimens, besides pointing out evolutionary trends in groups (Metcalfe & Chalk 1950;1979). Nonetheless, few studies exploring the anatomy of specific genera in Malpighiaceae are available in the literature, such as Mamede (1993), Araújo et al (2010), Possobom et al (2015), Araújo & Meira (2016), and Mello et al (2019).…”

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

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.

“…The floral architecture of all species in Malpighiaceae is very similar; therefore, characters such as leaf shape, length, width, and leaf pubescence as well as the extremely diverse fruit types are commonly used to sort out species within several genera (Anderson 1979;Mamede 1981;Davis et al 2001). The phylogeny of Malpighiaceae is based on molecular analyses, which include fruit morphology, pollen grain morphology chromosome number, and distribution of species (Davis et al 2001;Cameron et al 2001); however we could not find evaluations that included anatomical characters.…”

Leaf anatomy as an additional taxonomy tool for 16 species of Malpighiaceae found in the Cerrado area (Brazil)

et al. 2010

This work describes the leaf anatomy of 16 species belonging to three genera of the Malpighiaceae family found in the Cerrado (Minas Gerais State, Brazil). The scope of this study was to support the generic delimitation by contributing to the identification of the species and constructing a dichotomous identification key that includes anatomical characters. The taxonomic characters that were considered to be the most important and used in the identification key for the studied Malpighiaceae species were as follows: the presence and location of glands; presence of phloem in the medullary region of the midrib; mesophyll type; presence and type of trichomes; and presence, quantity, and disposition of accessory bundles in the petiole. It was also possible to indicate promising characters for future taxonomic and phylogenetic studies in the Malpighiaceae family, especially for the Banisteriopsis, Byrsonima, and Heteropterys genera.
