MASHILE, SP  and  TSHISIKHAWE, MP. Leaf architecture characters of Vachellia tortilis (Forssk.) Galasso and Banfi along longitudinal gradient in Limpopo Province, South Africa. Phyton (B. Aires) [online]. 2015, vol.84, n.2, pp.473-477. ISSN 1851-5657.

This paper looked at the leaf architecture characteristics of Vachellia tortilis to determine if either there is or not an effect of the tropic line on plants. Vachellia tortilis leaves were sampled along a national road (N1) in Limpopo province. Sampling points were set 10 km apart away from the Tropic of Capricon in opposite directions. Leaf morphology revealed that leaves of V. tortilis are bipinnately compound with alternate arrangement. The venation pattern of the pinnules was eucamptodromus and brochidodromous with imperfect reticulation. Areoles were imperfect and pentagonal or irregular in shape.

Keywords : Pinnules; Eucamptodromus; Brochidodromous.
