Venus' Looking Glass

Triodanis sp.


Small wildflower native to the Americas. This is either Triodanis biflora or Triodanis perfoliata. The flowers look almost identical. These species are differentiated by their vegetative growth. T. biflora is commonly called Small Venus' Looking-glass; T. perfoliata is called the Clasping Venus' Looking-glass. T. biflora has a slender stalk with non-perfoliate leaves (leaves not through the leaves) and few flowers. T. perfoliata growth is much heavier in appearance with perfoliate leaves and many flowers. In this area, T. biflora begins blooming a little earlier than T. perfoliata but the blooming seasons overlap.


Native to the Americas. This one was observed at the Stork Ponds at the Silver Bluff Audubon Center in Aiken County, SC.
