“…However, other characteristics like the structure of the mesophyll, stomata, outline of epidermal cells, crystals and phenolic compounds, characterize the affinity of occurrence in the evaluated species, corroborating Zoric et al (2012). Therefore, especially in the absence of fibres in the mesophyll and presence of hydathode trichome is shared by species that are distributed in areas with more intense flooding, seen in A. denticulata, A.…”

“…For some species of Aeschynomene the types of trichomes are essential in species identification (Lima et al, 2006), and studies made by Zoric et al (2012) with species of Fabaceae reinforce the importance of trichomes and crystals in the identification of taxa, besides other anatomic characters that aid delimitation of sections of the genus.…”

We present the leaf anatomy of seven amphibious species of Aeschynomene L. (Papilionoideae, Leguminosae), interpreting their structures and ecological functions, and also, providing information on which their taxonomy can be based, especially of morphologically similar species. We evaluated Aeschynomene americana, A. ciliata, A. evenia, A. denticulata, A. fluminensis, A. rudis and A. sensitiva. The anatomy corroborates the separation of the series Americanae, Fluminenses, Indicae and Sensitivae, with the shape of the petiole, types of trichomes and quantity of vascular units in the petiole as main characteristics to delimit the species. The petiole shape varies from cylindric in A. americana, A. sensitiva and A. fluminensis, to triangular in A. evenia and quadrangular in A. rudis, A. denticulata and A. ciliata. We observed four types of trichomes: hydathode trichome, long conic trichome, short conic trichome and bulb-based trichome. The hydathode trichome was the most common, except for A. americana and A. fluminensis. Species with higher affinity with water share similar adaptive characteristics, including hydathode trichomes described for the first time for the genus. This article adds unseen descriptions for the genus and on the adaptation factors of the amphibious species.Keywords: macrophytes, Fabaceae, hydathode trichome.

Some plant species belonging to Trifolium L. genus are a source of isoflavones considered to exert phytoestrogenic activities. The aim of the present study was to examine the effects of standardized extract obtained from aerial parts of Trifolium medium L., in comparison with the extract of Trifolium pratense L., on the development of estrogen deficiency-induced osteoporosis in rats. Both Trifolium extracts, at doses corresponding to 10 and 20 mg/kg of isoflavone aglycones daily, or estradiol (0.2 mg/kg daily), were administered orally to ovariectomized (OVX) rats for 4 weeks. Serum bone turnover markers, bone mass, mineralization, and mechanical properties were studied. In OVX control rats, mechanical properties of the tibial metaphysis and femoral neck were strongly worsened in comparison with sham-operated control rats, and those of femoral diaphysis were unaffected. Estradiol counteracted the worsening of the tibial strength and increases in bone turnover markers. Both extracts significantly increased the strength of the femoral diaphysis and calcium and phosphorus content in the bone mineral, but only T. pratense extract increased the strength of the tibial metaphysis. In conclusion, effects of both Trifolium extracts differed from those of estradiol. It is possible that other than isoflavone extract constituents contributed to their skeletal effects.

“…The Trifolium genus (Fabaceae) comprises of about 240 species of clovers (Zoric et al, 2012), occurring in temperate and subtropical regions of both hemispheres. The Mediterranean basin, western North America, and the highlands of eastern Africa are the three geographic regions with the greatest diversity of Trifolium species, while no species are native to southeastern Asia and Australia (Ellison et al, 2006).…”
