ERYSIMUM. 
E. caespitosum comes from Northern Persia, and forms most fas- 
cinating dense grey cushions, almost shrubby, with stems of some 
4 to 6 inches carrying heads of immense lemon-gold flowers as in 
E. helveticum. There is also a variety of this called H. c. brachy- 
carpum. 
E. canescens, from Southern Europe, is only about 2 inches taller, 
with stars of similar colour. 
E. comatum has very long and very narrow greyish leaves, splayed 
out in a wide and most elegant rosette ; the 10-inch spike comes up 
in the middle, and does not do it so much honour, for the flowers, 
though large, are thin and floppety, alike in texture and arrangement ; 
while their tone is rather a starved-looking lemon-yellow than the 
fervent orange that pictures sometimes present. (Balkan States.) 
E. deflecum is a most tiny plant from the Kongra Lama Pass, some 
15,000 feet up on the Roof of the World. Its hoary little leaves are 
only about half an inch long, and its twigs bend down to hug the 
inhospitable ground, and there end in smallish blossoms of ochre- 
yellow. 
E. dubium, Suter, is the valid name of £. ochroleucum. 
EH. elbrusense, on its eponymous mountain, mimics Alyssum 
montanum in golden heads, from a densely hoary tuft of quite narrow 
foliage. 
[H. filiforme. See under F. linifolium.] 
EH. gelidum is like the last in habit and blossom and stems of 
only an inch or two in stature, with flowers of the same orange-gold. 
But here the hoary leaves are oblong spoon-shaped, and the lower 
ones have longish footstalks of their own. There is a variety, 
E. g. Kotschy, which is even more minute and close and dwarf and 
delightful. 
HE. helveticum is usually taken as a mere stunted variety of 
HE. longifolium. It occurs on the warm slopes in open places here 
and there, in tufts of narrow grey-green leaves, and then heads of 
large clear-yellow blossom on stems of some 8 inches or so, beset with 
foliage. 
Hi. Hookeri will be found treated under its less correct name of 
Cheiranthus Griffithii. 
E. Kotschyanum has huddled dense tufts of especially narrow pale- 
green leaves running to a point, and toothed or often rolled over at 
the edge ; from this rise stems of a few inches, carrying a few splendid 
blooms of orange-yellow in a loose head. From the high screes of 
Asia Minor in Lycia, Caria, Pisidia, &c. There is a tighter-tufted 
alpine form still, H. K. rwpicola, not more than 2 or 3 inches in the
