Watercolour painting on paper of a specimen of the Cassia occidentalis plant. The painting is on a double sheet of paper that has been folded in half. The painting shows a branch of the plant with numerous smaller stems growing off it. These have multiple small lanceolate shaped leaves of a dark green colour. Off the central branch are four bunches of yellow flowers. The painting is framed by a line border.

This painting comes from a collection of four watercolour paintings which depict natural history subjects and were likely painted in Calcutta where natural history drawings were popular during the late 18th and early 19th century. These paintings are of a superior quality to paintings produced for the general consumer. Such paintings were vital to botanists in India and in England and helped further the study of the flora of the Indian subcontinent.
