Podotheca angustifolia
Podotheca angustifolia, commonly known as sticky longheads, is a species of herb native to Australia. Description. An annual herb with yellow flowers, "P. angustifolia" grows in a range of habits, from trailing along the ground to erect; when erect if can reach up to 30 centimetres in height, but is usually no more than 20 centimetres. It has a swollen, almost succulent stem, and a slender woody taproot. It is sticky due to secretions from its glandular hairs. Taxonomy. This species was first published by Jacques Labillardière in his 1806 "Novae Hollandiae plantarum specimen", under the name "Podosperma  angustifolia". In 1826, Alexandre Henri Gabriel de Cassini transferred it into "Phaenopoda", but this was overturned six years later by Christian Friedrich Lessing, who placed it in "Podotheca". Distribution and habitat. It occurs in southern parts of Australia. It has been recorded from Tasmania but is now presumed extinct there.
