Etymology
The name Nestegis is of unknown origin, since the author Constantine Eugene Rafinesque often invented generic names from scratch. It may have no meaning at all or it may derive from Greek stegos (στέγος) meaning "cover" in allusion to the lack of a corolla in the type species, Nestegis apetala.
Description
Nestegis species are evergreen trees or shrubs. The leaves are opposite, simple, entire, and coriaceous. The inflorescence is axillary, decussate, sometimes terminal and somewhat paniculate. The flowers are either bisexual or functionally unisexual. The corolla is either absent or four-lobed with a short tube. There are two or four stamens. The ovary is shaped like a flask. The fruit is a drupe containing a single seed.
