SAXIFRAGA. 



8. NeU niana is a dense tuffet from Arctic America, with tho

' — The history of this preposterous name is probably 



. as follows. A handsome hybrid Euaeizoon appeared, being 



clearly the result of -S'. Cotyltdon with, probably, 8. Hostii, but, as was 



jidata. Now S. ligulata is a Himalayan Bergenia, 



and what more easy than for catalogues to confuse S. Ungulata with 



Accordingly, the supposed result of S. Ungulata was 



: -rred to the responsibility of S. ligidata, and, to supply it with 



local coluur. was giv I habitation and a name, from a part of 



the world where no Euae;z_>< >n Saxifrage exists (the whole group being 



confined to Europe and the far North, with an extension of 8. aeizoon 



by th I ;s into America). In cultivation the hybrid is a 



tall grower, stalwart and free, with varying characters suggesting 



7 and S. Hostii, no less than S. Cotyledon. The white fi< 

 are less heavily freckled with red than in the best forms of 8. 

 abiana. which is merely an improved version of this. 

 «S'. nervosa, VilL, is a dwarf form of 8. exarata, q.v. In gardens 

 the name is often used for little Mossies of the Hypnoeides group. 



: se native, and our only Boraphila. High up in the 

 country, Snowdon, and Scotland, it makes dark tight rosettes of 

 very thick and leathery sombre obovate leaves, wavy and scalloped 

 at their edge ; in the middle comes up a naked little stem of 3 inches 

 or so, bearing a huddled head of small white stars. It grows easily. 

 but, apart from its interest as a native alpine, has no conspicuous 

 ity or charm. 



S. nootkana stands near S. stellaris in the Boraphila group. It is 



■lalled S. 8teUar%6 Brunoniana, and also 8. leucanthemifolia 



Branoniana. Ail three species, together with the Himalayan 8. 



9a, may be held to be comparatively recent developments of a 



common original, probably arising in Northern Asia. The essential 



oddity of S. nootkana is that while the main branches on the sprays 



end in a perfect flower, the lateral ones always bear only red bulbils 



that drop off and propagate the plant. 8. strigosa has the same habit, 



and it occasionally appears even in 8. stellaris.

comes in the neighbourhood of S. diversifolia. It is a

 . nodding spires of pale-yellow blossoms, whose calyct
