Emex 34/1/2024 australis is an annual that can only reproduce by seed ( Gilbey and Weiss, 1980). Other common names such as cat's head, bull head, devil's thorn and goat head are presumably based upon the visual resemblance of the achene, when viewed from the side so that only two of the three spines are showing, to an animal/devil head with the spines on the achene being the horns/ears.Į. Common names incorporating the word "jack" presumably refer to the children's game in which small 6-pointed metal pieces are picked up whilst bouncing a ball. It was also known as Cape spinach as the young leaves are palatable and can be eaten as spinach ( Gardner, 1930) however, soon after being imported into Australia, the plant became troublesome and was more likely to be referred to as tanner's curse ( Gilbey, 1975). The common name most frequently used in Australia, doublegee, is derived from dubbeltjie, an Afrikaans word meaning devil's thorn ( Gilbey, 1975 Gilbey and Weiss, 1980). The species name, australis, is Latin for 'southern' and refers to its southern African origins. The genus name Emex is thought to be derived from Rumex, the genus to which it was originally placed and the Latin word 'ex', (out of) ( Shivas and Sivasithamparam, 1994). The type specimen for Emex australis Steinheil (1838) was collected from the Cape of Good Hope, South Africa.
