  • REMARKS: Wadi Wurayah National Park (WWNP). When not in flower, Panicum turgidum and pennisetum divisum look very similar. Distinguishing characteristic: when the leaf sheath is removed in P.turgidum, the insertion of the branching stem is glossy and bulbous ('turgidum' means 'swollen') and covered with short hair (visible only with a magnify-ing lens). In P. divisum the insertion is thin and without hairs. In the latter plant the branches divide at more acute angles than in P. turgidum.
