86 DIADELFHIA. HEXANDKIA. 



2, membranaceous, each bearing 3 anthers, 

 Capside siliquose, many-seeded. 



Caulescent, rarely stemless; leaves muUipartite, some- 

 times imperfectly bipinnate or biternate, the rachis notun- 

 frequently terminated by tendrils; flowers in terminal ra- 

 cemes; corolla witii 1 or'i2 calcaraie nectaries at the base. 



Species. 1. C. CiicuUaria. Obs. Calix unequal, 4- 

 leaved, leaves decussated, 2 of them linear and acumi- 

 nate, the 2 others appressed to the corolla, ovate, acumi- 

 nate. Petals 2, saccate at the base, limb hooded and re- 

 flected, filaments 6, distinct, 3 arising from each petal, 

 central filament calcarate at tlie base. Thalamus connate 

 above, partly panduriform, dorsally crested, hollow and 

 impervious, with rugose folds. Capsule lanceolate-ovate, 

 many-seeded. Stigma compressed, somewhat reniform. 

 Root a granulated'scaly bulb, a bulbous enlargement pro- 

 duced at the base of each leaf, finely spotted with red; 

 leaves radical, ternate, partitions subbiternately divided, 

 ultimate segments incisely toothed, roundish at the extre- 

 mity, with a short setaceous point; raceme secund, flow- 

 ers nodding, white with a yellowish limb; bractes obvallate, 

 short and acuminate. — Mr. Bosk i^roposed this plant as a 

 distinct genus under the name of JDichjtra. My. Pursh af- 

 terwards proposes another name intended to include the 

 first section of this genus with bicalcarate flowers; it does 

 not, however, prove to be natural, as there is almost a dif- 

 ferent structure in each individual; for instance, Cformosa 

 and C.fungosa accord with the genus in having 2 trianthe- 

 riferous filaments, notwithstanding this discrepancy, the 

 habit, of C.forjnosa and C. spectabilis is too similar to that 

 of C. Cucullaria ever to admit of any separation. 2./or- 

 r.wsa. o.tenuifoUa. Ph. A.fungosa. 



§11. Corolla unicalcarate. — 5. glmica. 6. aurea. 

 Siberia, Japan, and Europe afford most part of this ge- 

 nus of 25 species. 



488. FUMARIA. i. (Fumitory.) 



Cato 2 leaved. Corolla irregular; calcarate 

 at the base. Filaments 2, each bearing 3 an- 

 thers. Capsule valveless, 1 -ceiled, 1 -seeded. 



Habit similar to that of the preceding genus. 

 Species. 1. F. officinalis. Introduced.— A genus of 

 8 species, indigenous to Europe, Siberia, and Barbary.
