Peltandreae

The tribe was first described in 1876 by the German botanist Heinrich Gustav Adolf Engler (Engl.).^[2][3] Engler placed Typhonodorum in a separate tribe Typhonodoreae.^[7][8][9] However, it is now included in Peltandreae.^[10][1]

Peltandreae consists of the following two genera:^[4]

• Peltandra Raf.
• Typhonodorum Schott

It is closely related to the European tribes Ambrosineae and Arisareae. These three tribes shared a common ancestor about 82.7 million years ago.^[1] 60 Million years old Peltandreae fossils have been found in Europe, North America, and Central Asia.^[4] Therefore, the group has existed for at least 60 Million years, as the evidence of the fossil record suggests,^[4] but the analysis of the molecular clock suggests this group is about 82.7 million years old.^[1]

The precise relationships are displayed in the following cladogram:^[1]
