Gnephosis is a genus of about sixteen flowering plants in the family Asteraceae, all endemic to Australia. Plants in the genus Gnephosis are hairy annual herbs, the upper leaves arranged alternately, the lower leaves sessile and arranged in opposite pairs. The flowers are arranged in narrowly elliptic to oblong heads with up to 300 flowers, each with up to 16 bisexual florets. The achenes are pink or pale purple and more or less cone-shaped, sometimes without a pappus.[2]
Taxonomy
[edit]The genus Gnephosis was first formally described in 1820 by Henri Cassini in the Bulletin des Sciences par la Société Philomatique de Paris, and the first species he described (the type species) was Gnephosis tenusissima.[3][4]
Distribution
[edit]Plants in the genus Gnephosis occur in all Australian states and the Northern Territory.[2][1]
