Peltandreae is a tribe of plants in the arum family.[1][4]
Distribution
[edit]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]
Taxonomy
[edit]Taxonomic history
[edit]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]
Genera
[edit]Peltandreae consists of the following two genera:[4]
- Peltandra Raf.
- Typhonodorum Schott
Phylogeny
[edit]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]
