Abstract:
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.
