Abstract
The seed morphological characters and protein electrophoretic profiles of seed 15 taxa belonging to the Mimosoideae were investigated to reveal further seed characters which may be useful in further distinction and delimitation of the examined taxa.
The different seed morphological attributes of the studied taxa are presented in the form of commulative tables, photomicrograp and plates as well as photographic picture of seed protein electrophic profiles.
An artifical key has been contrasted based on morphological surface scan characteric (lens character) of seeds of the studied taxa. In addition the data produced from seed protein electrophoretic profiles were treated by the numerical analysis.
I) Seed Morphology:
1. The shape of seed seems to be a reliable criterion for characterization of some of the examined taxa at both the species and infra specific level.
Although, the size and colour of seeds are frequently inconsistent attributes, and thus they are not among the valuable taxonomic ones. They here stand diagnostic form some the taxa investigated.
2. The areole which represent an area on each face bounded by crack in the testa (the pleurogram) is recorded in seeds of all the taxa examined.
3. The presence of three apertures (the micropyle, hilum and lens) altogether at one end of the seed is a common feature among the taxa investigated, however the lens is not detected in seeds of Acacia tortilis subsp tortilis.
a) The micropyle shape may be useful in the recognition of Albizia julibrissin from A. Lebbeck.
b) Also in the delimitation of the two examined species of Enterolobium: E. contortisiliqum, E. cyclocarpum (Deltoid slit with thickened rim) from all the remaining as they retain a similar shape of micropyle.
c) In addition, the micropyle position appear, to be diagnostic for Faidherbia albida and also for the recognition of Prosopis farcta from P. julifora.
4. The hilum shape seems to be distinctive for Acacia farnesiana (conspicuous), Faidherbia albdie (Elongate with funicular rement).
5. The lens characteristics proved to be diagnostic taxonomic attribute. These characters are position in relation to hilum, lens level of insertion and lens shape. The combination of such characteristics together may be very useful in the delimitation of the taxa investigated primarily at the specific and infra specific level.
a) An atrifical key based on lens characters are constructed.
b) The lens when detected is invariable located behind the hilum and is separated from the micrpyle by the hilum.
