Mount Cotton was collected in Uganda by the University of Hawaii. Seed of a number of accessions of S. sesban including ILCA 15036 was sent to The University of Queensland for evaluation in Australia. Morphological description Sesbania sesban is a shrub or small tree to 6 m in height. It branches well from the main stem, which can be up to 10 cm in diameter. Stems are usually pubescent.
Flowers are yellow, commonly flecked or speckled with red-brown.
Mount Cotton has glaborous stems with a red-brown coloration at the base. It has a larger number of branches from the mainstem than the species norm. Agronomic characters Sesbania sesban regenerates rapidly after cutting or grazing. In south Asia and Africa it is widely used as a forage in 'cut and carry' livestock-feeding systems. It is reasonably tolerant of cool temperatures but does not withstand frost.
