322 Yellow to Orange Flowers 



minal racemes. Fruit: pods didymous, variable, with large, strongly 

 inflated cavities, emarginate at base and summit. 



A most curious and interesting plant, which grows on 

 high rocky slopes and forms patches upon the ground by 

 means of its rosettes of pale green leaves and decumbent 

 stems. The little yellow flowers are cruciform and incon- 

 spicuous, and grow in clusters at the ends of the long 

 slender stalks which spring out from below the central 

 rosettes of leaves, while an irregular circle of outer leaves 

 grows beyond them again. It is the large inflated pods, 

 of a delicate gray-green hue, which give this plant its com- 

 mon name and constitute its greatest attraction. They are 

 really exquisitely quaint, and so unusual as to always attract 

 the notice of the passing traveller. The leaves are spatu- 

 late and small. The name Physaria is derived from the 

 Greek, signifying '' bellows," and refers to the inflated fruit.
