Diclytra is compounded of the two Greek words, 
Dis, twice; and elytron, a sheath. The word 
is applied to this genus in allusion to the two 
sheaths, or protuberances, of the base of the corolla. 
Eximia, from the Latin, signifying choice, or select. 
The genus Fumaria, as originally established, 
included not only the plants which it now compre- 
hends, but also those of Corydalis, Diclytra, and 
two or three minor genera ; indeed the whole of the 
natural order, Fumariaceae, depended on it. The 
generic name, Diclytra, explicitly distinguishes its 
own species from most others of the Fumariaceae, 
in consequence of these having but one spur, or 
prominence at the base, in lieu of two. 
This is a desirable herbaceous plant for the flower 
border, not in reference to its blossoms alone, but 
also from its compact and neat foliage. Its flower- 
ing stems vary considerably in comparison with its 
leaves. They are taller as the season advances. 
A dry situation is usually thought best for it, but 
we have it in a light soil and rather moist situation, 
where it grows with exuberance. We prefer divid- 
ing it in spring.
