ACHILLEA. 
A. x Kellereri, however, is a really beautiful creation, one of the 
few fine hybrids of a race in which the species, especially in the high- 
alpine groups, interbreed with a freedom that results in a confusion 
of strains as dingy as their parents. A. Kellereri may well be an 
ornament to the choicest rock-garden—a mass of long, finely-cut 
leaves that suggest an Aspleniwm viride that has gone grey in a frost, 
and fine white flowers, ample and clear,an improvement on Clavennae’s, 
carried on loose heads at the top of 6-inch stems. Of much the same 
attractiveness are A. Jaborneggii, of similar habit, but with leaves 
perfectly green; A. macedonica of gardens, a doubtful species, in 
habit like Parrya Menziesti, in neat rosettes, but possibly belonging 
to A. serbica, which is really a false name of Anthemis aeizoon ; 
A. Morisii, like a tiny, depressed child of A. Jaborneggii ; A. Obristit, 
after the style of Huteri, rambling about the face of the ground on 
long weak trunks, each tipped with a rosette of oval leaves, deeply 
gashed into six or eight rather pointed lobes. 
A. pyrenaica, from the highest grass-banks and earth-pans in 
the Pyrenees of Catalonia, is a fine species, with pitted leaves deeply 
saw-toothed, and uprising stems, from 6 to 10 inches, clad in a few 
leaves, and carrying flowers larger than those of Ptarmica in a loose 
scant cluster. 
A. rupestris, however, though reduced unfairly to a mere variety 
of comparatively dingy A. Herba-rota by Fiori and Paoletti, remains 
far and away the most beautiful and valuable of the Achilleas for 
the rock-garden, now that the race has been stripped of the brilliant 
plume which it long unjustly claimed for its own clan, and which has 
now at last, though not in catalogues, been allowed to rejoin its own 
family as Anthemis aeizoon. A.rupestris belongs to South Europe, and 
is quite dwarf, with tiny leafy rosettes, perfectly green, more or less 
glandular, and perfectly smooth at the hem, without toothing or gash 
or scallop—at least in the lowest leaves of the rosette, for the inner 
ones often have a little irregular gashing at their base. The plant 
spreads readily into a neat mat, and sends up numerous 6-inch stems, 
carrying loose heads of ample pure white flowers with whitish eye.. © 
A. serbica is simply yet another false name by which Achillea 
still tries to claim the beauty of Anthemis aeizoon, q.v. 
A. sericea is a rank Milfoil after the style of our own Yarrow, but 
with wide heads of mustardy yellow, from the Balkans. 
A. tomentosa is, however, the best of this section, a comparatively 
neat little thing, with the usual fine foliage, densely downy to the 
point of being woolly. The habit is that of a dwarf and tidy Yarrow 
—such a Yarrow as would not dishonour an edging—but the broad
