FUMARIACE.-E. 37 



closer texture, and they generally prefer a position slightly 

 shady. They are beautiful ornaments of rockwork. 



C. "bulbosa, syns. C. solida and Fumaria solida {Bulbous C. ) 

 — The roots are tuberous, as indicated in the specific name ; the 

 stems are unbranched, and the leaves much divided in the 

 ternate manner. Flowers pale purple or pink, in terminal 

 compa.ct racemes, appearing in February or later, according as 

 the season is mild or severe, and lasting a couple of months. 

 Height 9 inches. Native of Europe generally, and has been 

 naturalised in a few places in Britain. J\lay be cultivated in 

 the open border or on rockwork, and is valuable for introduc- 

 ing into shady dry banks, and with a handful or two of soil 

 will luxuriate among the debris of old ruins. 



0. lutea ( Yellow C.) — It is doubtful whether this is a true 

 perennial, but as it reproduces itself abundantly by seed, the 

 question is of less importance to the purposes for which it is 

 best adapted — those of adorning ruins and old walls, and dry 

 open woods and banks ; and it certainly is more durable than 

 most biennial plants. It belongs to the fibrous-rooted section, 

 and produces branching angular stems clothed with ternately- 

 divided leaves, the stems and branches teniiinating in short 

 loose racemes of yellow flowers. Height about i^^ or 2 feet 

 •in rich light soil, but much more dwarf when growing in dry 

 gravelly or stony places. Flowers in spring and throughout 

 the summer. Native of Europe generally, and of several parts 

 of England. 



C. nobilis {Noble C.) — This is perhaps the finest of the group, 

 and is certainly a very choice and beautiful plant. It requires 

 rather more generous treatment than most others of its relatives, 

 luxuriating best in partial shade on rockwork, with a tolerable 

 depth of soil of a rich but porous gritty nature. Iti)elongs to 

 the tuberous-rooted division, and produces erect unbranched 

 stems, much-divided pale-green leaves, and dense racemes of 

 bright yellow flowers. Flowers in May and June. Height 

 about 9 inches or i foot. Native of Siberia. 



C. tuberosa {Tuberous C.) is near in character to bulbosa, 

 but has darker purple flowers. It is valuable for similar pur- 

 poses, and the white-flowered variety, C. t. albiflora, is an in- 

 dispensable companion to it in any position : it is synonymous 

 v>'ith Fumaria cava albiflora. Flowers same time as bulbosa, and 

 about the same in height. Native of Europe. 



Dielytra is not so numerous in species as the preceding, 

 but all are perennial plants adapted to a variety of purposes of 

 embellishment. They grace any position in which they may 

 be placed j and while they are at home in sunny exposures,
