Trembleya phlogiformis is a species from Cerrado, used in the mining communities as natural dye to engrain wool and cotton used in hand looms. This work presents the morphological and the anatomical study of the leaves and of the young stems of this plant. The botanical material was collected in the Serra dos Pireneus, Pirenopólis, Goiás, Brazil. The Macroscopic characterization was performed with the naked eye and with a stereoscopic microscope. For the anatomical study the sections were free hand and were stained with Alcian blue/safranin 9: 1 and chemical tests with ferric chloride, Steinmetz reagent and lugol. T.phlogiformis is a shrub with sticky, simple, cross-opposite leaves; flowers arranged in dicasio with free petals ranging from pink to white coloration. The leaf is hypostomatic with omocytic stomata, epidermis coated with thin cuticle and multiseriate glandular trichomes and glandular capitate trichomes. These results constitute the first anatomical description of T. Phlogiformis and contribute to the identification of the species. [ABSTRACT FROM AUTHOR]

This paper aimed to collect, to characterize and to estimate the phenotypic divergence of Dimorphandra spp. from different regions of Brazil. Dimorphandra species are sources of rutin, quercetin and rhamnose for pharmaceutical industry. Fruits at mature stage were collected from 21 areas, totaling 84 trees in cities of Minas Gerais, Maranhão and Tocantins states. The following descriptors were used to characterize the collected fruits: mean fruit fresh weight; mean seed fresh weight; fruit length and diameter; length, diameter and thickness of seed; seed color; number of viable and unviable seeds per fruit, and boron content in mesocarp and endocarp. The data were analyzed using a standardized average Euclidian distance matrix. The areas were clustered based on Neighbor Joining algorithm. Phenotypic variability among areas was detected. The clustering of the groups was consistent with geographic region of the collection and the species were separated in different groups. The D. wilsonii Rizz. species was the most divergent considering the three studied species. However, for germplasm conservation, more expeditions to collect samples are needed to increase the effective population number and to ensure an adequate accuracy to assure the occurrence of minimal genetic erosion.
