“…raddiana; and medium in A. ehrenbergiana, A. laeta, A. negrii and A. nilotica (Table 1). This result is almost similar to that reported by Tantawy et al (2005) and Kordofani and Ingrouille (1992) on the pollen grains of A. tortilis ssp. raddiana and almost similar to that reported by Rajurkar et al (2013) on the pollen grains of A. nilotica.…”

“…The pollen shape is round in Acacia ehrenbergiana, Acacia laeta A. nilotica and Acacia tortilis ssp. raddiana (Figures 1, 3, 5, 7; Table 1), this result confirms that mentioned by Kordofani and Ingrouille (1992), Tantawy et al (2005) and Rajurkar et al (2013). Shape is semiround in Acacia farnesiana, A. negrii and A. oerfota Table 1), and this in an agreement with report of Tantawy et al (2005).…”

“…Guinet (1990) noted that the pollen structural symmetry was shared by some Mimoseae and Acacia. Kordofani and Ingrouille (1992) studied 14 species of Acacia reporting that the pollen grains in each polyad are16 except in one species which has 32 grains in each polyad. Fitzgerald et al (1993) studied the development and initiation of cohesion between compound pollen grains of Acacia paradoxa and found special cases of pollen development.…”

Pollen micromorphological characters such as pollen size, shape, number of associated monads, colpi and ornamentation of the tectum surface, of seven species of Acacia belonging to the family Mimosaceae were studied, using light microscope (LM) and scanning electron microscope (SEM). The study showed that the pollen size range from 42.1 to 69.4 µm, pollen shape is round to semi-round, the number of associated monads is 16 or 32, and the colpus is Y-H shaped. The tectum surface ornamentation among the species is variable, it is foveolate in Acacia ehrenbergiana; psilate-foveolate in Acacia nilotica, Acacia laeta and Acacia negrii; and micro-reticulate in Acacia farnesiana, Acacia oerfota and Acacia tortilis ssp. raddiana. An artificial key based on micromorphological characters is provided.

The morphological features used to separate sub-taxa in the A. tortilis complex are largely overlapping and the taxa display www.elsevier.com/locate/foreco high phenotypic plasticity (Brenan, 1957(Brenan, , 1983El Amin, 1973, 1976Täckholm, 1974;Ross, 1979;El Houri, 1982;Kordofani, 1989;Kordofani and Ingrouille, 1992). However, the morphological characters may very well be phenotypic expressions of ecological factors (both biotic and abiotic).…”

“…The pollen of Acacia is one of the more extensively studied with regard to its morphological aspects (Guinet 1964(Guinet , 1969(Guinet , 1981(Guinet , 1986(Guinet , 1990Guinet & Lugardon 1976;Caccavari & Dome 2000a, 2000bElazab 2005). Pollen characteristics have been correlated with other morphological characteristics, and used to reconstruct phylogenies (Sorsa 1969;Kordofani & Ingrouille 1992;Rico & Banks 2001).…”

The study of pollen grains of Acacia asak showed a marked pollen dimorphism of smooth exine (psilate) polyad type A and rough exine (scabrate) polyad type B, when examined using light microscopy (LM) and scanning electron microscopy (SEM). Typical pollen grains of Acacia asak are 16-monads. Both acetolised and non-acetolised grains of the two types were studied, measured, described and illustrated using LM and SEM. The main differences between these and the functional significance are discussed. Polyad dimorphism can be used as a character to distinguish between A. asak and otherAcacia species. In this study, two polyad types are recorded from the same anther of A. asak for the first time, possibly related to pollination function. However, the function of polyad dimorphism in the same anther is still unclear and requires further study.
