Description
Plants in this genus may be annuals or perennials. They are erect and may be with or without hair. The sepals are saccate (shaped like a pouch or sack) and have two forms. The petals are clawed and drawn out into a long, narrow apex. There are six stamens. The fruit opens 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]
