Glabrous and 



much-branched, the young branches angular or sulcate. Leaves vertically 

 ilattened but thick and rigid, linear or lanceolate, usually falcate, with pun- 

 gent or rarely almost callous points, | to 1 in. long, the edges thickened, 

 usually naiTowed towards the base. Flowers small, usually clustered on a 

 very short peduncle, with minute bracts. Pedicels slender, 1 to 2 in. lon^. 

 Calyx scarcely 1 line long, the turbinate base very short, the teeth small, the 

 2 upper ones veiy obtuse or truncate. Petals more than twice as long as the 

 calyx, the keel much incurved, almost rostrate. Filaments slender. Pod 5
