Spec. Char., $c. Spiny; spines branched, spreading, striated, glabrous. 

 Leaves simple, very few, oblong, somewhat silky. Flowers glabrous, upon 

 short pedicels, in groups disposed somewhat racernosely ; the keel as long 

 as the standard. Legume containing 2 4 seeds. (Dec. Prod., ii. p. 148.) 

 A native of the south of Europe and in Barbary, in arid places, producing 

 its yellow flowers from March to April. It was' cultivated by Parkinson in 

 1040, and forms a spiny shrub, almost leafless, when the shoots are full 

 grown. This species is commonly thought to be the Scorpius of Theo- 

 phrasttlfl. Parkinson says it is so covered by thorns as to be quite inac- 

 cessible; from which it would appear to be a desirable plant for low hedges 

 in suitable situations. In British gardens, it is occasionally met with as a 

 curious shrub, and in conservatories in old collections.
