and which is not inappropriate to this form, where the pedicels 

 are as long as the axis of the fruiting raceme, except that, in 

 the cultivated and some wild specimens, the raceme elongates 

 in fruit to the length of three or four inches, as in the sue 

 ceeding.

 Summit of hills, in large patches, on stony soil, New Braun- 

 fels. March, in flower. Accords entirely with the original 

 specimens. What Scheele has taken for this species is evi- 

 dently V. recurvata, at least in part. 



327. V. Lindheimeri (sp. nov.) : radice crassa perenni ; 

 caulibus decumbentibus foliosis cinereis ; foliis oblongis ar- 

 gute sinuato- vel laciniato-dentatis imis lyrato-pinnatifidis pube 

 implexa appressissima (e pagina superiore sero subdecidua) 

 argenteo-incanis ; racemo fructifero elongato ; silicula ovoideo- 

 globosa glaberrima stipite plus duplo stylo subduplo longiore ; 

 seminibus immarginatis. — Black, stiff prairie soil on the lower 

 Guadaloupe, east of Victoria. February, in flower and fruit. 

 — This appears to be a truly perennial species, and is remark- 

 able for its strongly toothed leaves, as well as for the matted, 

 extremely fine and close-pressed, silvery pubescence which 

 clothes them. The upper surface of the older leaves, how- 

 ever, is merely cinereous with minute and rather sparse 

 stellar down. Petals apparently light yellow, three or four 

 lines long. 



328. V. bensiflora (sp. nov.) : annua v. biennis, pube 

 stellata laxa cinerea ; caulibus adscendentibus usque ad flores 

 foliosis ; foliis oblongo-spathulatis vel oblanceolatis basi atten- 

 uatis saepius repando-denticulatis, radicalibus integris; race- 

 mo etiam fructifero denso multifloro, pedicellis erectiusculis ; 

 silicula estipitata subdepresso-globosa glaberrima stylo bre-
