SAXIFRAGA. 



843 



leaves densely set in cushioned masses. The 

 yellow flowers appear in summer, and are 

 arranged in spikes on a leafy stem. S. jnni- 

 perina thrives in moist, sandy, firm soil, and is 

 well worthy of a place in the rock-garden. 

 Caucasus. Seed and careful division. 



S. lantoscana. One of the finest of the 

 incrusted-leaved section. Though similar to 



broadly obovate leaves, bearing flowers in 

 small cymose panicles. The flowers are 

 white, with a rosy tint towards the margin of 

 the petals and crimson anthers. Its early 

 growth renders it tender, and repeated injury 

 is fatal. It should therefore have shelter and 

 a little shade. The varieties rubra and 

 speciosa, particularly the latter, are finer than 



Saxifraga longifolia. 



the pyramidal variety of S. cotyledon, it is 

 smaller, its leaves narrower and more crowded, 

 whilst its slightly drooping flower-spike is 

 more densely furnished with flowers. It is 

 easily grown in a fully-exposed position in well- 

 drained gritty soil. It remains long in flower, 

 and is one of the best of alpine plants. S. lin- 

 gulata comes very near this, and indeed 

 S. lantoscana is now classed as a form of it. 

 S. ligulata (Nepaul Rockfoil). This has 



the type, and thysanoides bears pale flowers. 

 S. ligulata may be associated with others of 

 the Megasea section. 



S. longifolia. This Pyrenean plant has 

 single rosettes often 6, 7, and 8 in. in dia- 

 meter. Its greyish leathery leaves are beauti- 

 fully dotted with white on the margins, and 

 in early summer it pushes up fox-brushlike 

 columns of white flowers from I to 2 ft. long, 

 the stems covered with short, stiff, gland-tipped
