458 THE VEGETABLE WORLD. 
The SaxtFRAGACE®, derived from saxum, “a stone,” and f/rango, 
“T break,” from their supposed virtues as a specificin calculus, are 
characterised by a calyx free or united to the ovary and divided 
into five segments, a corolla of five petals, ten stamens, awl- 
shaped filaments, and roundish anthers. Of the species twenty- 
four are British, most of them true rock plants, many of them 
old favourites, as S. wmbrosa (London Pride, None so Pretty, and 
other popular synonyms), usually made an edging plant in old 
cottage gardens. They also abound in North America, and Pro- 
fessor Martins found them with other old favourites on the rocky 
declivities of North Cape. The Canonacex are of frequent occur- 
rence in Australia, beyond the tropics, and at the Cape of Good 
ope. Cunonia capensis is in great request for its timber, which 
is called Red Alder, or Rood Els. The Hydrangeas are met with 
in Northern India, Japan, and North America.
