“…Many anatomical characters of the leaves are useful for systematics, particularly the epidermal cells and stomata (Metcalfe and Chalk 1979, Dickison 2000, Araújo et al 2010, Inceer and Ozcan 2011. Paradermal sections taken from the leaves show that C. macropus has isodiametric epidermal cells together with anomocytic stomata.…”

-In the present study, the micromorphological structure of achene, pappus and style using scanning electron microscope (SEM), stomatal characteristics, anatomy of stem and achene together with chromosome number and nuclear DNA content of the Turkish endemic Crepis macropus Boiss. & Heldr. are provided in order to expand knowledge of its taxonomy. The SEM studies in this species show that dense spiny cells are found on the achene surface, the pappus bristle has 3-5 spikes and the style possesses slender papillae. The stem structure is composed of epidermis, collenchyma, parenchymatous cortex and pith. The species has anomocytic stomata in both the upper and the lower surface of the leaves. The pericarp of the achene is mainly composed of several layers of sclerenchymatous cells. In this species, the chromosome number is 2n = 2x = 8, karyotype consists of two submetacentric and six subtelocentric chromosomes and nuclear DNA content (2C-value) is 12.96 pg. These data are presented here for the fi rst time and their taxonomic values are discussed.

“…Gates and B. malifolia B. Gates were selected since these species had already been analyzed by Araújo et al (2010), which made the identification and collection in the field easier. Samples of vegetative and floral branches of these three species were collected in Cerrado in the Floresta Nacional -FLONA (MG, Brazil) and samples of B. campestris were also collected in campo rupestre in the Serra do Ouro Branco (MG, Brazil) State Park.…”

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.

Micromorphological studies were carried out using multiple microscopic techniques on the leaves and stem bark of Byrsonima sericea DC. (Malpighiaceae), a species popularly known as “murici” and used medicinally, in order to identify both qualitative and quantitative features of leaf and stem anatomy and histochemistry as differential parameters to support both the quality control of its ethnodrugs and the taxonomy of the genus. The study was conducted using traditional techniques of plant anatomy, histochemical tests, and the stomatal index (SI). Byrsonima sericea has hypostomatic leaves, anomocytic stomata, and its epidermal walls are anticlinal and straight on the adaxial and curved on the abaxial faces. T‐shaped trichomes were observed mainly on the abaxial surface. The leaf epidermis showed waxes syntopism on both surfaces, with the occurrence of different crystalloid forms on a single phylloplane. The mesophyll is dorsiventral, with 3‐4 collateral vascular bundles. Phenolic compounds, starch, and proteins were identified in the petiole and stem. The SI was 14.5 ± 0.53% (p < .05), but did not showed significant variations. A set of characters were found to be distinctive for the studied species, however, constituting parameters that could be used to separate B. sericea from other species of the genus.
