“…The number 2n = 26 observed in M. arenosa, M. ophthalmocentra, and M. tenuiflora confirms previous counts, as well as the basic number x = 13, suggested in the literature for the genus (Dahmer & al., 2011;Santos & al., 2012;Freire & al., 2013;Rodrigues & al., 2017). In turn, the chromosome numbers 2n = 24 and 2n = 18 observed in A. colubrina and P. stipulacea, respectively, differ from the number reported in the literature for these species, 2n = 26 (Gibbs & Ingram, 1982;Alves & Custódio, 1989;Ortolani & al., 2010;Santos, 2017), which may indicate new cytotypes originated from dysploidy processes from x = 13. Regarding Piptadenia, only P. obliqua (Pers.)…”

-(Leguminosae at APA do Cariri, Paraíba State, Brazil). Leguminosae Juss. is a largely distributed family, being dominant in several dry ecosystems, such as the Caatinga woodlands. This work deals with the taxonomic survey of Leguminosae at the Cariri Environmental Protected Area, semiarid of the Paraíba State, Northeast Brazil. Thirty-one species were found in the total, 22.6% of which accredited as endemic to the Caatinga. The most taxonomically diverse genus was Senna, with five species. Seven species were recorded for the first time to the Paraíba State (C. belemii var. belemii, D. violacea, I. blanchetiana, P. microphilla, V. halophila, Z. echinocarpa, and Z. myriadena). The shrubby habit was the most representative, with 45.2 % of the total of registered species, followed by herbaceous and tree habits, with 22.6 and 16.1 %, respectively. Vines and lianas totalized 9.7 and 6.5 % of the species, respectively. This treatment includes keys for separation into subfamilies and their species, a list of examined materials, data on geographic distribution, and illustrations.

Leguminosae Juss. é uma família amplamente distribuída, sendo dominante em alguns ecossistemas, como na Caatinga. Este trabalho trata do levantamento taxonômico de Leguminosae na Área de Proteção Ambiental (APA) do Cariri, semiárido paraibano, nordeste do Brasil. Foram encontradas ao todo 31 espécies, 22,6 % das quais acreditadas como endêmicas da Caatinga. O gênero mais diverso taxonomicamente foi Senna, com cinco espécies. Sete espécies foram referidas pela primeira vez para o Estado da Paraíba (C. belemii var. belemii, D. violacea, I. blanchetiana, P. microphilla, V. halophila, Z. echinocarpa e Z. myriadena). O hábito arbustivo foi o mais representativo, com 45,2% do total de espécies registradas, seguido pelos hábitos herbáceo e arbóreo, com 22,6 e 16,1% respectivamente. As trepadeiras e lianas perfizeram respectivamente 9,7 e 6,5% das espécies. O tratamento taxonômico inclui chaves de identificação para subfamílias e respectivas espécies, dados de distribuição geográfica e ilustrações.

“…The Anadenanthera colubrina can reach a height of 10 to 20 m, it is widely used in the planting of mixed forests and in the afforestation of parks (GOMES et al, 2004;ORTOLANI et al, 2010), due to its moderate to rapid growth (CARVALHO, 2002), and it can be used to control erosion and soil improvement (SANTOS, 1987). Because it is a dense, smooth and lustrous wood, with good resistance and great durability (CARVALHO, 2002;ORTOLANI et al 2010), this is indicated for use in planks, bats, carpentry, debris, internal works, slats, implements, packaging, shipbuilding and civil construction (CARVALHO, 2002).…”

PHYSICO-MECHANICAL CHARACTERIZATION OF THE Anadenanthera colubrine WOOD SPECIE

ABSTRACT:In Brazil, the characterization of wood is carried out in accordance with the premises established by ABNT NBR 7190standard; however, the determination of wood properties requires the use of equipment, which hinders the wood characterization for the construction professional. To circumvent this problem, the properties of wood strength and stiffness can be estimated through regression models using the apparent density as estimator, being the density a physical property of easy determination. This study aimed to determine 4 physical and 13 mechanical properties of "Angico Branco" wood (Anadenanthera colubrina), and with the aid of regression models based on analysis of variance, estimate the strength and stiffness properties as a function of apparent density. Twelve samples were produced for each test, resulting in a total of 204 experimental determinations. The results of mechanical properties showed consistent performance with other wood species studied, demonstrating their potential use in various applications. From the regression models, only the longitudinal modulus of elasticity in parallel compression to the grain showed a significant result, and the best were obtained with the linear model, which provided determination coefficient (R 2 ) equal to 56.32%.
