The generic name before us is compounded of 
Greek words, signifying four-angled pod, see No. 
375. Siliquosus, alludes to the seed vessel forming 
a siliqua ; that is, a long dry pod, having the seeds 
attached alternately to each stem which unites the 
valves or sides of the pod. Stocks, and other spe- 
cies of cheiranthus, are familiar examples. The 
legume, on the contrary, as our common pea, has 
them attached to one seam only. These are botani- 
cal distinctions which cannot have escaped the notice 
of even the careless observer. 
The stems of this plant spread frbm the root, on 
the surface of the soil, whilst the extreme ends of 
the shoots and lateral branches are raised from four 
to six inches high ; producing their yellow flowers 
through several successive weeks, which are succeed- 
ed by singularly- formed four-angled pods. It is 
nicely suited for ornamenting the lapidium, or stone 
border ; where the plant, reclining on stones and spar, 
is shown to the greatest advantage. 
Plant it in a dry situation. Divide in spring only, 
when it begins to vegetate. Sow seeds in April, in 
rich soil, and a warm situation.
