which are placed between the edges of the valves, and 

 bear the seeds on short stalks. 



Jussieu doubted whether the spongy cellular body, in which 

 the seeds are sunk, were really a partition ; but the mem- 

 branous, likewise cellular, indubitable partitions of G. vio- 

 laceum^ prove the true nature of that body, and he was 

 too judicious to separate this last-mentioned species ge- 

 nerically from the rest. Prof. Hooker having examined 

 only one species, G. luteum, was led by Jussieu into a mis- 

 take, and found fault with Gaertner's figure of G. phceni- 

 ceum^ which is peculiarly excellent and correct. 



Annual or biennial herbs, mostly glaucous, with yellow fetid 

 juice. Leaves more or less pinnatifid and subdivided ; 

 the upper ones sessile. Flox<oers solitary, stalked, lateral 

 or terminal, yellow, scarlet, or violet, very handsome.

Biennial. July, August. 



Root spindle-shaped. Plant very glaucous. Stems spreading, 2 

 or 3 feet long, round, branched, leafy, smooth. Radical leaves 

 numerous, stalked, a span long, pinnatifid, lyrate, lobed, cut, 

 hairy, lasting through the winter ; stem-leaves sessile, less rough, 

 short, broad, lobed, and cut, clasping the stem with their heart- 

 shaped base. Flower-stalks]nterd\ and terminal, smooth, scarcely 

 so long as the calyx, which is rough with short hairs, falling off 

 as the flower opens. Petals 1 \ inch long, of a golden yellow, 

 certainly answering rather to the latin word Jlavus than to lu- 

 teus, but the latter appellation has been most generally adopted. 

 Pud nearly a foot long, curved, roughish with minute tubercles, 

 never hairy, rarely quite smooth. The.spongy substance of the 

 partition is united with the lateral receptacles, by which indeed it 

 is formed, and this union is )>ermanent. The surface of the 

 seeds, in every species, is curiously cellular.
