SAXIFRAGA. 



blunter, with quite short (hardly any) purplish stems, carrying from 

 one to three dull-white flowers, always erect in hud. 



8. calyciflora, Boiss. and Rout., is the far better and .more ex- 

 pressive, but unfortunately subsequent and ten years younger, name 

 of 8. media, Gouan, q.v. 



8. Camposii has nothing whatever to do with the glorious garden 

 hybrid 8. x Wallacei which sometimes pretends to bear it. The 

 true species is a neat cushioned Mossy, an extremely rare and fine 

 mass, almost wholly hairless and fairly sticky, with the leaves three- 

 lobed, and the two side-lobes again cloven, and each gash ending in a 

 point. The stems are stout, carrying dense clusters of chalk-white 

 flowers ; and the plant may always be known by the fact that theso 

 scapes are slightly winged — that is, with a little leafy line or rim running 

 down along them. 



S. canaliculata is a much more beautiful Mossy from the limestone 

 Alps of Calabria, up to the snow level. It forms wide aromatic cushions 

 of deep dark lucent-green foliage, fleshy and sticky. The branches 

 are woody from the base, and the rosettes packed at their ends, with 

 very long and deeply-grooved stems to the leaves, which are cut into 

 three lobes, and then the two laterals gashed again, and perhaps 

 again, all the lobes being firm and quite narrow and pointed, deeply 

 grooved like the petioles, which characteristic will always distinguish 

 the plant whose name it has earned. These broad and shining hassocks 

 send up abundant erect trusses of large white flowers. 



8. Candelabrum is a Chinese monocarpic novelty of rather tender 

 nature, with tender green leaves arranged in a most lovely wide 

 rosette of fine foliage. The flowers are unfortunately tarnished in 

 their brightness by the conspicuous narrow segments of the calyx, 

 standing out between the petals. 



8. capitata seems likely to be a hybrid between 8. aquatica and 

 the much smaller 8. ajugaefolia, whose name it is sometimes made to 

 bear in gardens. It is by now a fixed species, occasionally seeding, 

 " though rarely in cultivation," but varies greatly, either towards the 

 one parent or the" other. Some hold it, though, a mere form of 

 8. aquatica, q.v., and in gardens it is identical with 8. aq. aprica, 

 while it belongs in nature to districts where 8. ajugaefolia is unknown. 



8. carinthiaca. See under 8. aeizoon, of which it is a local form. 



8. carniolica. See under 8. aeizoon, of which it is a local form. 



8. caroliniana. See 8. pennsylvanica. 



8. cartilaginea, Willd., in all probability only a form of 8. aeizoon, 

 is treated in its place here because it is always made in catalogues 

 a synonym of lovely S. Kolenatiana, Regel — though the true species
