SAXIFRAGA. 



declares, a prior synonym for S. thessalica and S. porophyUa too, 

 thru it will have i<> embrace also the spine-leaved grey species 

 with the bells smaller and of darker purple, in closer spikes than the 

 loose blanched spires and ample claret-coloured fluffy bells associated 

 with the broad-leaved forms. Hitherto the name of 8. porophyUa 

 has been associated with the spine-leaved plant called also S. thessalica 

 and S. Bcrtoloni, rather than with the broad-leaved, big-belled species, 

 which is 8. media, and the true 8. porophyUa, and probably also the 

 true S. Fedcrici Augusti. For fuller notes on the tangle, see under 

 S. Bertoloni. 



S. x Portae offers yet another form of the hybrid between S. in- 

 cruskUa and 8. aeizoon, with close-set, attractive rosettes of narrow 

 Leaves widening towards the tip, where they also have a saw-edge of 

 sharp toothing. The stems are short, hairy and glandular, often tinged 

 with rod, and bearing the same stodgy little ugly creamy flowers in 

 which the group is so fertile. 



S. primuloeides. See under S. umbrosa. 



S. Probynii, a false name for the minor form of S. cochlearis, q.v. 



S. Prostii = S. pedatifida, q.v. 



S. pseudo-Kotschyi is the due name of the plant described earlier 

 under S. " Kotschyi " of gardens, q.v. 



S. pseudo-sancta, Janka, comes quite close to S. juniper if olia, from 

 which it is impossible to distinguish it (except by its greater and more 

 universal healthiness), so long as there are only the dense mats of 

 fine dark spiny shoots to judge by. The flowers, however, are wholly 

 different, though carried on exactly the same stems ; for they are 

 both larger and brighter, with oval three-nerved petals of rich yellow, 

 emerging clearly from a very baggy green calyx, fluffy with glands, 

 and with sepals much inflated and of light yellowish -green. So that 

 these little greenery-gallery clusters mako far more of an effect on 

 their many little 2-inch stems in early spring, than do the dowdinesses 

 of S. juniper if olia. This species often serves in gardens for S. sancta. 



8. pulvinaris is a form of 8. pedemontana. q.v. 



8. punctata is a North-Asiatic Boraphila, with tufts of long- 

 stalked kidney-shaped leaves, broadly toothed. The stem branches 

 only at the top into few-flowered sprays, the blossoms being white 

 stars with a large purple ovary in the centre. 



8. x pungens is a hybrid between 8. marginata and S. juniper if olia ; 

 the result gives small cushioned tufts of packed and tiny dark-green 

 rosettes of the Marginata type, but minutely liny and so closely over- 

 lapping thai hardly more than their tips are visible. They are not 

 blunt, however, but with a minute firm point. The stoms are 2 inches
