This member of the Iridaceae family was given this name by Nicholas Edward Brown in 1932. It have been named by others, but this name seems to be the most frequent used. It is found in south and south-western South Africa, and have been naturalized in southern Europe and Australia. I've seen so many in Ireland. It prefer a rich clayish soil with some water and some sun. The bulb can grow to six centimetres in diameter, the entire plant to 60 centimetres in height. The flowers are deep orange.
The genera name from Greek; chasmamai; ' yawning or gaping ' and anthos; ' flower '.
The species name aethiopia usually referred to the whole of Africa south of Egypt at the time of naming. Later, it have been used for the tropical part of Africa. This is a winter-grower. A small group from Wikimedia.com. A group from Knowyourweeds.com.
