Taxonomy
In the last three decades of the 20th century, Canna species have been categorised by two different taxonomists, Paulus Johannes Maria Maas from the Netherlands and Nobuyuki Tanaka from Japan. Inevitably, there are differences in their categorisations.
Maas considers Canna discolor to be a synonym of C. indica L., however, Tanaka's studies have revealed that C. indica can be clearly distinguished from other taxa, as a result he recognises several varieties:
- Canna discolor var. discolor (Lindl.) Nb.Tanaka, 2001
A triploid, sterile both ways.
- Canna discolor var. rubripunctata Nb.Tanaka, 2001
Green leaves with yellow flowers and many red spots. Seed parent sterile.
- Canna discolor var. viridifolia Nb.Tanaka, 2001
No details available.
