Glebionidinae is a subtribe of flowering plants in the tribe Anthemideae of the family Asteraceae. Its members include species used in the production of garden marguerites.
Description
Members of the subtribe are either subshrubs (Argyranthemum) or annual herbs (the remaining genera). The genus Heteranthemis has glandular hairs; the others either lack hairs or have non-glandular hairs. The flower heads (capitula) are solitary or arranged in loose corymbs. The ray florets are female, the long petal (ligule) usually being white or yellow. The disc florets are hermaphrodite with a five-lobed corolla. The achenes of the ray florets are three-angled and have two or three wings; those of the disc florets are flattened and have one or two wings.[2]
Taxonomy
The subtribe was first proposed in 1993 by Bremer and Humphries, under the name "Chrysantheminae". The name was validly published at the time, but two annual species placed in the tribe, which were then known as Chrysanthemum coronarium and Chrysanthemum segetum, are now placed in Glebionis. (The genus Chrysanthemum is now used for perennial Asian species, such as the conserved type C. indicum.) Hence Chrysantheminae Bremer & Humphries became a later homonym of Chrysantheminae Less. and so illegitimate. In 2007, Oberprieler and Vogt provided a new name, Glebionidinae, based on the genus Glebionis, whose type species is Glebionis coronaria, formerly Chrysanthemum coronarium.[2]
Genera
The subtribe comprises four genera:[2]
- Argyranthemum Webb, about 24 species
- Glebionis Cass., two species
- Heteranthemis Schott, one species
- Ismelia Cass., one species
Distribution
Genera belonging to the subtribe are native to Macaronesia, Europe, northern Africa and southwestern Asia.[2]
