“…Seeds of Schizolobium , at 2.0 g oven dry weight, are unusually large for a pioneer plant (Ibarra‐Manríquez and Oyama, 1992; Souza and Válio, 2001; Daws et al, 2007; Bentos et al, 2008) and for a wind‐dispersed legume (Oliveira and Pereira, 1984; Augspurger, 1986). The large seeds allow Schizolobium to germinate and establish in pastures where grasses preclude establishment of small‐seeded pioneers.…”

This unique pattern of development should provide an extended period of growth when SG is low, facilitating hyper-extension of the bole, at some risk of structural failure. Later in growth, the SG rate of increase accelerates, reinforcing what was a precarious bole. Overall, these results suggest a third model for xylem allocation in tropical trees, a model that may be associated with monopodial stem development and limited life span.

“…De acordo com Oliveira e Pereira (1984), Groth e Liberal (1988) e Barroso (1999), tanto as características externas quanto as internas das sementes são pouco modificadas pelo ambiente, constituindo-se em um critério bastante seguro para a identificação de famílias, gêneros e, às vezes, espécies. No entanto, poucos manuais e trabalhos são específicos para identificação e, na maioria deles, a morfologia de sementes é ignorada ou recebe tratamento secundário, sendo, portanto, inadequados, pois as sementes são conservativas na sua morfologia e freqüentemente evidenciam caracteres familiares (Gunn, 1981, Oliveira, 1993.…”

O presente trabalho teve por objetivo descrever a morfologia dos frutos, das sementes e o desenvolvimento pós-seminal de faveira (Clitoria fairchildiana R. A. Howard. - Fabaceae). Os frutos e as sementes foram caracterizados quanto à forma e dimensões. Periodicamente, unidades representativas de cada fase de germinação foram retiradas para as descrições morfológicas. Os frutos são do tipo legume, deiscentes e de coloração marrom. As sementes são exalbuminosas, de forma orbicular e achatada, com tegumento de coloração castanho-esverdeada. O hilo tem forma elíptica, homocromo e de tamanho pequeno em relação à semente. Os cotilédones são livres, de coloração verde, maciços e plano-convexos e o embrião é invaginado. O início do desenvolvimento pós-seminal é marcado pelo rompimento do tegumento e emissão da raiz primária, glabra, de coloração amarelo-esverdeada e de forma cilíndrica. Posteriormente, observa-se o desenvolvimento das raízes secundárias, levemente esbranquiçadas, curtas e filiformes. Em seguida, o crescimento do hipocótilo proporciona a emergência dos cotilédones e da plúmula acima do substrato. O epicótilo alonga-se e, em seguida, observa-se a expansão dos eófilos, simples, opostos, com tricomas simples e esparsos, pecíolos curtos com estípulas em sua base. Posteriormente ao desenvolvimento dos eófilos, ocorre a formação do segundo par de folhas, alternas, trifolioladas, estipuladas e com estipelas na base dos peciólulos.

“…The outer bark is smooth to finely cracked, light gray in color, with abundant conspicuous lenticels, suberified and prominent lenticels, arranged in longitudinal rows (Pennington & Sarukhán 1998). Within its geographical distribution one can find it in some units of the Federation, such as Acre (Oliveira 1994;Araújo & Silva 2000), Amazonas (Ducke 1949), Mato Grosso (Rondon 2002), Pará (Albrechtsen 1975;Oliveira & Pereira 1984;Parrota & Almeida 1995;Amorozo 1997;Gibson & Leão 1997;Jardim et al 1997),…”

Much of the vegetation in the State of Tocantins belongs to the Cerrado domain, widely known for hosting several species and forest families, among which the Fabaceae family stands out. However, misguided practices, incipient public policies, and few studies on the subject culminate in the loss of species found in the Cerrado of Tocantins. The present work aimed to elaborate a dichotomous key through dendrological characters. This study was carried out at the Federal University of Tocantins, Gurupi campus, which consisted of expeditions, and a collection of branches of tree species of the Fabaceae family in order to describe the vegetative characters. Seven species belonging to the Fabaceae family were analyzed, four from the Mimosoideae subfamily and three from the Caesalpinioideae subfamily. Characteristics such as bark color, extrafloral nectary, hairiness, and leaf classification allowed us to notice the differences between each sampled species. It can be inferred that the dendrological key of forest species of the Fabaceae family is fundamental for forest inventories and management plans of botanical species of the Cerrado Domain.
