Barnadesia lanceolata D. Don
- Common Name:
- Family: Asteraceae Giseke
- Country of Origin: Peru
- Habitat:
- Description: Barnadesia is one of the most interesting members of the daisy family or Asteraceae. In 1987, Jansen and Palmer discovered that the whole family Asteraceae (some 20,000 species) shared a 22 kilobase inversion in the chloroplast DNA, with the sole exception of the Barnadesia group (88 species), which had normal chloroplast DNA. These results are strongly suggestive that a split between the Barnadesia group and the rest of the Asteraceae was the earliest evolutionary event in the family, and this has been confirmed by subsequent research.
One of 9 genera in Barnesioideae, this subfamily is defined by the axillary spines of a type unique in the family, and by a unique type of long unicellular hair that is found on all parts of the capitulum.
