Peltandreae is a tribe of plants in the arum family. [1] [4]
The distribution is disjunct. Peltandra is native to Eastern North America and the Caribbean (Canada, USA, Cuba) [5] and Typhonodorum is native to Africa (the Comoros, Madagascar, Mauritius, Tanzania). [6]
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]
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.
