ERODIUM. 
and are white—but smaller than in HZ. chrysanthum, and smaller still 
than in ZL. absinthoeides. (From the Alps of Cilicia and Caria.) 
Group IV.—PETRAEA 
Flower-scape always springing straight from the stock: no true or 
branching stem at all; leaves gashed to the base on each side as in 
the last growp, but always with a secondary little lobe between 
the main strips. A group of small dainty treasures. 
E. cheilanthifolium (E. trichomanefolium, Boiss.), which is found 
in the mountains of Southern Spain and Morocco, is the same in habit 
as these last four, but may be known by being densely wrapped in 
hoary-grey down. (EH. trichomanefolium is evidently what usually 
passes for this in cultivation.) There is also a precious dwarf variety, 
E. ch. valentinum, which forms into perfectly tight mounded tufts 
barely half-an inch high, of compressed leaves especially velvety with 
thick grey down. (High Alps of Valentia, Pico de Penagolosa, Sierra 
de Javalambre, &c.) 
E. Choulletianum is a more remote and doubtful species from Oum 
Settasini, Algiers—the same in habit as LH. macradenum, but with the 
finely-feathered foliage vested on both surfaces in dense pressed-down 
short hairs. The flowers are reported violet and equal-petalled. 
E. macradenum differs in the first place in being wholly green and 
smooth, glandless and bald—except sometimes for a few spreading hairs. 
The leaves have the same finely ferny design, but here the pink 
blossoms with their pointed-oval petals have the two upper ones 
smaller than the rest, and freaked with a most dainty black blotch of 
radiating darkness which gives each delicate-veined pale flower a 
most ingenious and fascinating expression of innocent worldliness. 
(From the high limestones of the Pyrenees.) 
E. petraewm.—Two- to six-inch stems, weakly ascending, and 
carrying, on fairy-fine foot-stalks, two or four spotless pale flowers 
with equal petals veined with deeper pink. The leaves spring only 
from the base and are very numerous, with stalks about half again 
as long as themselves, softly hairy. They themselves are more or 
less hairy and downy on each face, with a toothed lobule between 
each of the main lobes, which are narrow-oblong and lobed again. 
(From the high limestone rocks of the Upper Pyrenees, Narbonne, 
Montpelier, &c.) This whole Section, in fact, stands 
throughout as the upper-alpine development of the 
last, Gdwarfer accordingly, and without true stem.
