From our other similar species (in the genus Lindernia), it has 4 fertile stamens instead of 2. The flowers are tubular with flaring lobes; the lower lobes are lavender to blue; the upper lobes are white with blue streaks. The leaves are quite rotund to widely ovate, typically much wider than in the native Lindernia species. | |
