132 ON SEEDLINGS 



No. 5. Triternate, with the terminal lobe of the primary divisions 

 bi- or trifid. 



No. 6. Triternate with many of the larger lobes more or less cut. 



No. 7. Triternate, and much cut. (Nos. 6 and 7 in fig. 154 have 

 been cut off.) 



Ultimate leaves large, triternately multisect ; ultimate segments 

 ovate, cuspidate ; terminal ones obovate, cuspidate. 



Corydalis lutea, DC. (fig. 155). 



Hypocotyl erect, terete, glabrous, reddish, about 1 cm. long. 

 Cotyledons ovate or lanceolate-elliptic, acute, petiolate, gla- 

 brous, pale green, often mottled with red ; lamina sharply decurved, 

 6.5 mm. long, 3 mm. broad ; petiole terete, glabrous, subdilated at 

 the base, 7*5 mm. long. 



Stem herbaceous, short, stout, producing 

 flowering branches. 



Leaves simple, ultimately bi-ternatisect, 

 radical and cauline, alternate, exstipulate, petio- 

 late, glabrous, pale glaucous-green ; petioles 

 obtusely trigonous, or flattened above and sub- 

 carinate beneath, especially towards the base, 

 dilated and semi-amplexicaul at the base, gla- 

 brous. 



No. 1. Ternatisect ; terminal segment 

 rotund, trinerved, trifid ; lateral segments 

 rotund, entire or tridentate. 

 No. 2. Similar. 

 Ultimate leaves bi- to tri-ternatisect ; ter- 

 minal segment of each primary division cuneate, trifid, with obtuse, 

 mucronate teeth ; other segments oval or elliptic, entire or bi- to 

 tri-dentate or -fid, obtuse and mucronate at the tips. 



In C. nobilis the cotyledons are oval, oblong, obtuse, and 

 minutely emarginate. 



Fumaria Vaillantii, Lois. 



Hypocotyl erect, striated, glabrous, 10 mm. long, reddish. 



Cotyledons linear, acute, tapering to the base, entire, light green, 

 glabrous, indistinctly one-veined. 



Stem with primary internodes scarcely developed. 



Leaves multisect, petiolate, glabrous ; 1st leaf less divided than 

 succeeding leaves, cauline, alternate ; segments mostly trilobed, 

 the lobes being again bi- to tri-lobed ; lobes linear-lanceolate or 

 linear-oblong, acute.
