3. Draba. 

 5. ly. alpina. 



There are three varieties of this plant which deserve notice, 

 although differing principally in their size and degree of pu- 

 bescence. 



1 . major ; glabriuscula, foliis biuncialibus (siccitate reticulatis) 

 marginibus hie illic evidentissime dentatis. 



A large and very beautiful state of D. alpina, with very few 

 hairs on any part of the plant : its scape more than 3 inches 

 high, and, as well as the pedicels, quite glabrous. Calija; 

 very slightly hairy. Corymbs almost an inch in diameter, 

 of a deep bright yellow. 



2. intermedia ; pilosa, foliis pollicaribus (nee reticulatis) inte- 

 gris vel rarissime obsoletissime dentatis. 



Marginal hairs of the leaves long and simple ; those of the disc, 

 as well as of the scape, much branched : hairs few on the 

 calyx. Corymbs smaller than those of the first variety, and 

 the flowers generally paler. 



3. nana ; valde pilosa, nana. 



Leaves scarcely half an inch high ; scape about an inch, and, 



as well as the calyx, very hairy. 

 Inhabits the mountains of Lapland and Norway, and the 



arctic regions of America. West coast of East Greenland 



(Greville).
