Somewhat 3-nerved. &. H. Native of Siberia about Irkoutsk. 
A smooth herb, very much like Z. tinctòria, but smaller in all its

Cuneated, pubescent, narrowed at the base, somewhat spatulate 
at the top and blunt, 4 times as long as broad, twice the length 
of the pedicels, which are obconical at the top. ¢.H. Native 
of exposed situations on the sea-shore in Provence, and on the 
Sea-shore at Fanar, not far from the Bosphorus. Allied to 
I. orientale on the one side, and to J. tinctoria var. y hirsùta on 
the other. Leaves with acute auricles.

ing rock- work or the front of flower-borders, as they flower very 
early. They may be either increased by cuttings or seeds, the 
former will root freely under a hand-glass. ‘The annual and 
biennial kinds are only cultivated in botanic gardens, but as the 
latter flower very early in the season, they are worth introducing 
into flower-borders. They only require to be sown in the open 
ground, where they are intended to remain or they may be trans- 
planted. A dry light soil suits them best, as in wet land they 
are very apt to damp off in the winter,
