the far finer 8. aaneta. The 1 1 perifolia may always be known 



by the fact that its bruised leaves emit a strong smell of Juniper. The 

 spee'es forms flat masses i ily spiny dark-green tufts that are 



apt to die away brown in patches ; and the flowers appear in huddled 

 heads on green stems in early spring, but after those of 8. aancta. They 



quite inferior, the narrow yellow petals hardly emerging from the 

 inflated, shaggy dark-green calyx ; the bloom seems almost to be petal- 

 less, and to consist only of the stamens, which are very long and stick 

 far out in a golden spray. It clings to vertical cliffs throughout 

 the alpine regions of the Caucasus, passing into a minute and tight- 

 packed high -alpine variety. 8. j. Imchyphylla, from great elevations 

 in the E ide of the range.

*S'. x KeUereri (Sundermann, 1012). is another new and still rare 

 hybrid of the Engleria group. 



8. x kestoniensis is a small and lovely early-blooming cross-bred 

 Kabsehia, suggesting both S. Burseriana and 8. marginata. It grows 

 readily in an open choice place, making neat tuffets of small rosettes, 

 with rounded little grey silver-edged leaves. The flower-stems are 

 about 3 inches high, tall for the plant ; and the flowers, carried 

 in a loose head, are nobly ample and of the most brilliant white, ap- 

 pearing almost before any other of the race except , s '. Baneriana 

 magna, yet never appearing to feel the ravages of rime or rav, i 



8. x kewensis is a secondary hybrid between the " pink ''' 8. B 

 ana called " Iroingii" there raised, and 8. Federici-Augu-sti, Bias. 

 Of this it has the foliage and the six lime-pits along each leaf ; but the 

 cushioned habit is that of .S'. Burseriana, whose influence lingers also in 

 the larger flowers of dim lilac pallor. • : to the centre. It 



should be as good a grower as its two parents in similar conditions. 



8. x Kocl.il is a high-alpine hybrid between .V. biflora and S. oppo+iti- 

 folia. It has a loose and almost rampant habit, with flowers notably 

 large and brilliant on the tumbkd heaps. It answers well, if imper- 

 manently, to cool-moraine treatment. 



8. Kolenatiana, Kegel, is a very different proposition from the 

 comparatively coarse 8. cartUaginea, Willd. It has broad pointed

 leaflets, and ending in a branched -pre of which each spray car;
