NATURAL HISTORY OF PLANTS. 



Hence the flower is made irregular by the unilateral projection. 1 

 The ovary contains one or more ovules, 2 and the one- or many- 



Corydalis bullosa.

seeded fruit opens as in Dicentra. The seeds have an arillary crest. 3 

 Some seventy species 4 of this genus have been described, erect or 



1 When, as occasionally happens, the opposite 

 flower assumes a similar form, the flower Ik comes 

 accidentally regular, like that of a Dicentra. 

 This we have found the case in whole inflo- 

 rescences of C. cava. [See Gode., Mem. sur les 

 Fumariacees a Fleurs Irregvlieres et stir les 

 Causes de leur Irregtdarite, in Ann. Sc. Nat., 

 ser. 5, ii. 272. See also, on the androeeum of 

 Fitmariacece, Caruel, in Bull. Soc. Bot. de F, ., 

 xiv. 228 ; and on the general symmetry of the 

 flowers in this group, Eichl., in Flora (1865), 

 433, 449, 497, 513, 529, 545, in Mart. Fl. Bras., 

 Papav., 323, t. 68; — Buchen., in Flora (1866), 

 39.] — Pater {Organog., 227, t. 49, 50) has also 

 studied the symmetry of the parts by following 

 ■up their development. 



2 They have two coats. 



3 Resulting from the excessive development of 

 a little group of cells near the base of the raphe, 

 on the opposite side of the hilum to the micro- 

 pyle ; it has often been termed a strophiole. In 

 this genus the seeds have often an enormous 

 albumen at the time the fruit dehisce-*, without 

 any embryo. This developes ulteriorly in certain 

 species, just as in Eratithis.
