FLOWERS OF ROCKS, WALLS, ETC. 



The flowers are large and conspicuous, sweet-scented and attractive 

 to insects, and the stigma is provided with spreading lobes to assist 

 insects to alight upon it and cause cross-pollination. There are 2 

 honey-glands at the base of the 2 stamens. 



The seeds are dispersed by the wind or the plant's own mechanism. 

 The seeds are flattened, and this assists in their dispersal by the wind 

 when the pod has opened or dehisced lengthwise. 



The Wallflower is largely a rock plant or saxicolous, and grows on 



a variety of rocks gran-

 It is also a sand plant,
