Normally endosperm formation is accompanied by degeneration of nucellus. Persistent nucellus is termed as perisperm. The dust-like seeds of orchids have no endosperm. Orchid seedlings are mycoheterotrophic in their early development. In some other species, such as coffee, the endosperm also does not develop. Instead the nucellus produces a nutritive tissue termed perisperm.
