XL HOUND'S-TONGUE. CYNOaLOSSUM. 



Stout, erect biennials, clothed with rough hairs, which are, however, 

 more appressedand hoary than inmost Boragineous plants ; with long, 

 narrow leaves, and rather small, blue or purplish-red flowers, in simple 

 or forked, one-sided racemes. Calyx deeply 5-cleft. Corolla with a 

 short tube, closed at the mouth by prominent scales, and a spreading, 

 5-lobed, regular limb. Nuts rather large, depressed, attached laterally 

 to the base of the style, and covered with short, hooked prickles, so as 

 to make them very adhesive burs. 



A European and Asiatic genus, rather numerous in species, especially 

 if considered as including the little blue-flowered Omphalodes and the 

 white-flowered C. linifolium. These two species, formerly frequent 

 in our flower-gardens, are however sometimes distinguished with some 

 others as a genus by the nuts, which instead of being muricated all 

 over, have a raised, more or less toothed border. 

 Leaves hoary with rather soft appressed hairs. Flowers dull
