The flowers of Pachycarpus plicatus grow from leaf axils at stem tips in a few clusters of two to four flowers each. The acutely pointed sepals curve inwards slightly, in a saucer-shape around the corolla cup. The five corolla lobes curve elaborately, giving the corolla a broad base. Their middle sections curve inwards to shape the walls of the cup and lastly the pointed tips curve outwards again, forming an outwardly skewed S-shape.
The corolla lobes are free from each other nearly to the base. The corolla as well as the corona is creamy yellow with irregular maroon blotches, varying from faint to sharply coloured. The corona lobes have broad, upward curving tips, narrow waists and wedge-shaped bases, split down the centre. The staminal column with anther appendages and anther wings around the stigma is small and greenish yellow in the centre.
