 sons. Langsi.ie, Glasg., Dr. Brown. Abundantly on. the road near 

 Drumpellier, Glasg., Hopk. Common about Dumfries, Mr.ArnoLl. 

 Fl. July. O. 



Ten to twelve inches high. Stems solitary, branched above. Lower 

 leaves almost spathulate, all slightly pubescent, as well as the ra- 

 cemes and pedicels. 



4. L. fihhim [Imny Field Pepperivrirl), pouch ovate emargi- 

 iiate winged glabrous, style nearly half as long as the pouch, 

 cauline leaves sagittate toothed. E. B. t. 1803 {Thlaspi 

 hirtiwi) .

 F/. June. 1/. {^ , Hopk.) 



Six to eight inches high. Stems many from one root. Much resem- 

 bling tiie last, but whiter with the more abundant pubescence. 

 Stem and racemes hairy. Pod with, constanllt/ , a much longer style, 

 and in all my specimens not only free from scales_, but from hairi- 

 ness too. 



7. COCHLEARIA. 



1. C. officinalis {common Scitrvy- grass), pouch globose," radi- 

 cal leaves petiolate cordato-reniform entire or sinuated, cau- 

 line ones sessile oblong sinuated. Light/, p. 342, and p. 344 

 (C grcenlandica). E. B. /. 351, and t. 2403 (C. groen- 

 hmdica). 



Haij. Rocks and muddy places by the sea-coast, as well as upon the 

 elevated mountains. F'l. May. © . 



Varying in height from six inches to a foot or more, much branched, 

 especially the base. Leaves succulent, more or less entire, those 

 of the stem semiamplexicaul with their generally toothed base. 

 Flowers white. — I can see no difterence whatever in the C. grcenlan- 

 dica ; for the sinuated and toothed or entire leaves are extremely 

 variable marks, and such as no reliance can be placed upon. 



2. C. anglica {Englislt Scurvy -grass), pouch elliptical, radical 

 leaves petiolate cordate entire, cauline ones mostly sessile ob- 

 long more or less toothed near the base. Liehtf. p. 341. E. 

 J5./.552. 5 J i^ 



Hab. Rocks of Inch Columb (Icolmkill), Sibbald. Fl. May. 0. 



Smaller than the last and larger than the following, to which I think 

 it appi-oaches too near. In some of the lower cauline leaves the two 

 teeth near the base form a complete delta j and the pouch is very 

 similar.
