is not a native of Portugal, but of Siberia, according to the 

 Linnean herbarium. See Schrad. new. journ. bot. p. 183. If 

 the plant should prove distinct, it is undoubtedly referrible to 

 the genus Omphalodes.

/fuo-ose-fruited Hound's-tongue. PI. 



Cult. All the species are coarse growing plants, but the 

 flowers of some of them are very pretty. They are of the 

 most easy culture, growing in any soil or situation. They are 

 generally increased by seed, which should be sown in spring in 

 the open border. The greater number of the species are 

 biennial, and none are perhaps truly perennial.
