Pictetia

Summary
Pictetia is a genus of about eight species of trees and shrubs in the legume family with spiny stems and (in six of the eight species) spine-tipped leaflets. The genus is endemic to the Greater Antilles, but its closest relatives are in Mesoamerica and Africa. Description Species of Pictetia range from erect, single-stemmed trees to multi-stemmed shrubs. They can have smooth or scaly bark. The leaves and branches branch off from the stem in an alternate pattern. The stems are spiny, as are the tips of the leaflets in all species except P. spinosa and P. nipensis. The leaves are pinnately compound with an odd number of leaflets. The leaflets, like the leaves, are arranged in an alternating fashion. The flowers, which are the typical pea flowers of the Faboideae, are borne in racemes. The flowers either grow singly or in clusters along the raceme. The fruit is a flattened legume with prominent veins running along its length. Taxon
