also by offsets from the old roots. * * * The offsets, which 

 these plants produce but sparingly, should be taken off at the 

 time that the old roots are transplanted, * * * toward the latter 

 end of May." 



Linnaeus cites descriptions from a number of the early bota- 

 nists, giving them as synonyms of his E. Dcns-canis, or as varieties 

 of it. Thus Dodonaeus (Stirpium historiae pemptades, 1616, 203) 

 gives " Dens caninus' which Linnaeus regards as synonymous with 

 Evythroniuni Dcns-canis, as is also " Dcns-canis with broad and 

 rotund leaves," of Bauhinus (Pinax, Basiliae, 1671). But " Dens- 

 canis with narrow and elongated leaves," of the same author is 

 regarded as variety ^ under E. Dens-canis, and Gronovius's descrip- 

 tion given in a preceding paragraph, is ranked as variety y in Spe- 

 cies Plantarum, 1753. 



Among names used or proposed for use as non-Latin designa- 

 tions of ErytJironiuin, Trout Lily and Fawn Lily, have been sug- 

 gested by John Burroughs in Riverby, on account of the spotted 

 leaves, and because of the alert position which the two leaves 

 often assume. Spring Lily has been proposed, on account of its 

 early flowering, and the lily-shaped blossom. But as a colloquial 

 name, " Roosters " is the least suggestive of the plant meant. 

 This name is used in central New York, among the children 

 especially, because of the custom of " fighting roosters " with the 

 nodding flowers or buds, as is done with violets in New Jersey.
