“Parsonsia”的意思、由来-开放百科全书

Description

The leaves are opposite, the shape and size of juvenile leaves often bearing little resemblance to the adult leaves.^[2] The latex may be clear and colourless, pale yellow or milky white.^[2]

The flowers are green, white, cream, yellow, orange, red, pink or brown, sometimes with contrasting markings. These are followed by elongated pod-like capsules, the two follicles eventually separating to reveal numerous seeds with long, silky hairs.^[2]

Taxonomy

The genus was named and described in 1810 by botanist Robert Brown in his paper On the Asclepiadeae published in Memoirs of the Wernerian Natural History Society .^[6] He named the genus in honour of James Parsons (1705–1770), an English physician and Fellow of the Royal Society.^[3]

The generic name Parsonsia R.Br. (1810) is conserved against the earlier homonym Parsonsia P.Browne which was given to a genus in the family Lythraceae. The latter genus is now included in Cuphea.^[4]

Species

Cultivation

A species from New Zealand, Parsonsia variablis (Variable-leaved Parsonsia), was introduced into cultivation in England in 1847 as a greenhouse plant and was noted to have a sweet scent, however the flowers were regarded as "not very showy".^[18] This species is thought to be a form of Parsonsia heterophylla.^[11]
