rosulate leaves, spreading out like rays, and by the long slender 
erect scapes, bearing asecund raceme of small flowers,” but con- 
spicuous by their deep purple colour. M. Planchon, in his 
admirable monograph above quoted, enumerates no less than 
eighty-eight species of this smgular genus, which has its repre- 
sentatives in almost every temperate and warm country through- 
out the world. We have cultivated this species very successfully 
for several years in a warm greenhouse.
