DRABA. 
number of short golden-headed stems; but the broad leaves have 
that edging of stiff white bristles which assigns it at once to the 
section Aeizopsis. 
D. globifera, from the rocks of Ararat, makes a quite dense tuft, 
composed of rosettes like little balls of wool, with the leaves bristled 
at their edges and a trifle bearded at their points. The golden-yellow 
flowers are as in D. olympica, but slightly smaller. 
D. Haynaldii. See under D. aeizoon. 
D. hispanica has its name under false pretences, for Spain is not 
its centre, but merely its one pied a terre in Europe. The species 
ranges from Atlas and all along North Africa, at last effecting a lodge- 
ment on the hills of Southern Spain, where, however, it is abundant 
both on calcareous and non-calcareous formations. It is a magnificent 
species, the type out of which D. Dedeana has evolved an independent 
existence. But D. hispanica is much larger—a woody-rooted mass 
of rosettes, stout and shining, pale bright-green with long-pointed 
fringed leaves, the inner ones standing up and the outer spreading 
upon the column of bygone relics. The stems are stout and many, 
about 2 inches high, or less at the time they are carrying their golden 
flowers on pedicels of which the lower are so long that the blossoms 
seem to be borne in an almost flat head or umbel. 
D. Hoppeana, Reish. (D. Zahlbriickneri, Sauter) of the high Alps, 
is like a minute form of D. aeizoeides. But it may be known by its 
preference for non-calcareous soils, and most especially for not con- 
fining itself to rock, as D. aeizoeides almost invariably does, but 
always occupying the bare places and open earth-pans of the heights, 
in which situations it is a most familiar foe to all who have ever been 
there. For it is not a species of any charm, minute and tight in its 
tuft, rather minute and greenish-lemony in the effect of its little 
flowers on their scantily-furnished head. 
D. hystrix is an obscure swollen-podded plant from Afghanistan, 
horrid with the spiny remnant of its dead leaves, while the living ones, 
besides the bristle-teeth at their edge, are all clothed in spreading white 
hairs. 
D. imbricata is a tight mass quite like an Aretian Androsace, to be 
met with in stony places high in the Western Caucasus. It is very 
dense and very very wee; the very wee leaves being very tightly 
packed into very wee rosettes, on which, almost stemless—(but what 
stem there is being quite hairless)—appear heads of some five blossoms, 
intensely golden-yellow, succeeded by bulging fat pods. It is rather 
like D. rigida var. bryoeides, but still more minute, and of the most 
especial charm.
