THE SAXIFRAGE FAMILY. 



radical leaves on long stalks, deeply 3- 

 or 5-lobed. Flowering stems weak, only 

 2 or 3 inches long, with very few small 

 leaves, and 1 to 3 flowers, like those of 

 the drooping S. 9 but much smaller, the 

 petals scarcely exceeding the calyx. 



A high alpine or Arctic species, with 

 nearly the same geographical range as 

 the drooping S. 9 but usually not so 

 scarce. In Britain, it occurs sparingly 

 near the summit of Ben Lawers and Ben 

 Nevis, and more abundantly on Loch- 

 ia. August.
