Oenothera curtiflora (syn. Gaura parviflora), known as velvetweed, velvety gaura, downy gaura, or smallflower gaura, is a species of flowering plant native to the central United States and northern Mexico, from Nebraska and Wyoming south to Durango and Nuevo Leon.[1]
Taxonomy
The species remains widely known as Gaura parviflora, this name being published in 1830 and for a long time considered the correct name for the species. However, an overlooked but validly published name G. mollis had been published earlier by Edwin James in 1823. A proposal was made to conserve the name G. parviflora over G. mollis,[2] and this was accepted by the International Botanical Congress Committee for Spermatophyta, so G. parviflora remains the correct name.[3] The name G. mollis appears in some sources.[4]
Description
It is an annual plant growing to 0.2–2 m (rarely 3 m) tall, unbranched, or if branched, only below the flower spikes. The leaves are 2–20 cm (0.79–7.87 in) long, lance-shaped, and are covered with soft hair. The flower spikes are 20–30 cm (7.9–11.8 in) long, covered with green flower buds, which open at night or before dawn with small flowers 5 mm (0.20 in) diameter with four pink petals.[5][6][7]
Uses
Among the Zuni people, fresh or dried root would be chewed by medicine man before sucking snakebite and poultice applied to wound.[8]
Introduction
It is naturalized and often invasive in other parts of the United States, and in Australia, China, Japan, and South America.[4][9][10]
