Description

Plants in this genus may be annuals or perennials. They are erect, and may be with or without hairs. The sepals are saccate (shaped like a pouch or sack) and have two forms. The petals are clawed, and drawn out into long narrow apex. There are six stamens. The fruit open at maturity to release the seeds. There are four to twenty mucous seeds in each locule, arranged in two rows.[4]

Etymology

The name Stenopetalum derives from the Greek, stenos, ("narrow"), and the Latin, petalum, ("petal") and describes plants in the genus as having long, narrow petals.[4]
