“…The areole shape was linear oblong in Acacia saligna, oblong in Albizia julibrissin and A. lebbeck, ovaloblong in Acacia tortilis, Enterolobium contortisiliquum and E. cyclocarpum; broad oval in Acacia nilotica and Dichrostachys cinerea and oval in the remaining seven taxa ( Table 2). The testa sculpturing patterns observed under SEM were clearly variable among the taxa investigated (Table 2 and The seed morphological characteristics such as shape, colour, size and areole shape; if present, in combination with the testa sculpturing peculiarities observed under SEM had been found very useful in delimitation and identification of genera and species within family Leguminosae (Hussein et al, 2002 a, b;Taia, 2004;Abou-El-Enain et al, 2007 andAl-Gohary &Mohamed, 2007). Hussein et al (2012) stated that diversity in the characteristics of the micropyle, hilum, and lens of seeds of Mimosoideae, when observed under SEM, offer indispensable criteria for separation primarily at the species level and sometimes at the subspecies level as well as very rarely at the rank of genus.…”
