DRABA. 
D. algida, from the tops of Altai, has hairy stems and leaves that are 
oval-oblong and smooth above, but hairy below and fringed. 
D. alpina ranges all round the Arctic Circle, and then, by way of 
Korea, down through the mountains of China into the Himalaya, 
which it densely occupies, a neat and useful mass of soft oval- 
pointed rather large leaves, from which rise many stems of 4 inches or 
less, carrying heads of yellow blossom hardly big enough to justify 
the lax look of the leafage below—at least not after the brilliant and 
concise beauties that we inspected in the more noble earlier section. 
D. calycosa makes a dense clump in the crevices of Argaeus in 
Cappadocia. It is remarkable for keeping its calyx'even after the 
valves have fallen from the pod (D. rosularis, Boiss.). There is a 
variety, D. c. Aucheri, of larger size. 
D. cappadocica has much the charm and the habit of D. acaulis, 
but the stems are taller, and the hairs that clothe the plant are split. 
D, elegans is an obscure name, representing a species with golden- 
orange blooms, that makes small mats of rather stiffish foliage, arranged 
scantily in rosettes, and rough to the touch. (Cilician Taurus, &c.) 
D. incompta, from Western Tibet, &c., is a minute downy tuffet 
with shoots of about half an inch, and naked little stems ending in a 
bunch of leaves, and composing a rather loose mat. The variety 
D. i. persica is larger. 
D. mollissima and all its beauty may be imagined when we hear 
that it is like a silky-velvety version of Androsace cylindrica, with 
golden flowers-in heads at the top of minute stems. (Western 
Caucasus, &c.) 
D. ochroleuca has leaves hairy all over. The stems are huddled 
and low, with pale-yellow flowers, lengthening afterwards. (Summits 
of the Altai.) 
D. polytricha is D. Reuteri (Boiss. and Huet.), and a little treasurable 
mass of 3 inches wide, in the manner of D. acaulis, forming neat dense 
clumps in columns on the piles of dead leaves that never fall. The 
leaves are minute, very narrow-oblong, and the whole growth is 
clothed in simple white hairs; the ample yellow petals are much 
blunted at their end. (From alpine rocks of Turkish Armenia, &c.) 
D. repens, a quite green species emitting leafy runners long and lax. 
The foliage is narrow-oblong and pointed, untoothed, and decked with 
a little close sparse down. (From the grassy alps of Caucasus, &c.) 
D. rosularis. See under D. calycosa. 
D. tridentata is loose and rambling as D. repens, with the scanty 
leafage of the rosettes cut in two or three teeth on either side. 
The leaves are also obovate, roughish, and shortly downy.
