Flowers of the species of Dilatris are also chirally dimorph, but here both left- and right-handed flowers are found on the same plants. Two species, W. thyrsiflora and W. brachyandra, grow in permanently moist environments such as the banks of streams and seeps, whereas the other two, W. multiflora and W. paniculata, grow in locations that are dry, at least seasonally dry.
