9979 The only species. — Fumaria fungosa, Hort. 
and Miscellaneous Particulars. 
1503. Cysticapnos. From xvrn, a bladder, and xecTtvos, fumitory. A genus divided from Fumaria on account 
of its bladdery fruit. 
15C4. Diclytra. So named by Borckhausen, a German botanist, on account of the two spurs or pouches of the 
flower. Handsome herbaceous plants, frequently cultivated among choice collections of rare flowers. Their 
roots are impatient of cold and wet, and should therefore be planted in a warm dry border well exposed to 
the southern sun. 
1505. Adlumia. A name unexplained by its author, M. Rafinesque Schmalz. A tall climbing annual plant 
of little beauty in its flowers, but covering a large space in the course of a summer.
