SAXIFRAGA. 



Group XVI. Trachyphyllum. — This group is characterised by 

 close tumbled masses of narrow, stiff, glossy and often spinulous 

 little leaves, packed upon the wandering shoots, from which 

 stand up the stems of yellow or white blossom. Its best type 

 is 8. aspera. and any open culture suits the section so long as 

 the plants are not kept too dry and baked. (Summer.) 



Group XVII. Tridadylites. — Little flimsy annuals for the most 

 part., typified by our own S. tridadylites. (Spring.) 



With so much preface, an indication of its group will supply general 

 directions for each kind's culture, except in all such cases as need 

 special treatment. 



S. aconiiifolia stands half a yard high and is only Boykinia, q.v. 



S. adenophora, Boiss.=£. androsacea, q.v. 



S. adscendens. L.. is little more than a larger 5. tridadylites, not 

 quite so bronzed and blushing. It can only be grown from seed, 

 which it scatters freely. There is a variety S. a. Blavii. with 

 broader leaves on the little stems, and several flowers on each of 

 the branches. 



8. Aegilops. See under S. umbrosa. 



S. aeizoeidoeides (Micq.. 1865). — This ridiculous name stands for 

 a very doubtful find, recorded from the top of Mont Perdu, with 

 the usual leaves of S. aeizoeides, but toothed petals of white. 



S. aeizoeides is quite the finest of the Trachyphyllum group, and 

 almost the best of the race for any cool soil in a rather moist but quite 

 open Bonny and well-drained place, where it makes its matted masses 

 of fleshy bright -green foliage as freely as it does by every alpine stream, 

 and as freely sends up, but rather earlier in the summer, its many 

 stems of 4 or 5 inches, carrying many red-spotted stars of clear yellow, 

 with orange anthers and central disk of the ovaries, maturing to a 

 darker shade. It is a common plant, no less, in the alpine marshes of 

 Scotland and Northern England, and has developed also a saxatile 

 form that flowers much later in the summer. This is 8. aei. autumnalis 

 (the original S. autumnalis, L.). whose rather richer and more brilliant 

 blossoms may be seen, for instance, in the stark limestone cliffs on the 

 Western face of Ingleborough in late August. There is also a rich 

 striking form sometimes sent out as S. atrorubens, in which the flowers 

 are of a violent brownish blood-colour, deepening to more fiery tones 

 in their later stages ; as well as a most beautiful form with blossoms 

 of very brilliant and strong clear orange. This I have only once seen, 

 and, as a rule. 8. aeizoeides may be said hardly to vary, except into 

 the Atrorubent form ; for many years will show vou nianv miles of
