AND Multiplication in Erythronium 313 



While it does not bloom it brings only one flower. It is called 

 Dentali by Apotheckers in Stiermarck." 



In Lobelius' Stirpium, Antwerp, 1576, there is a good cut on 

 page 64 of Erjtlironium with the brief description : " Erythroniinn 

 with colored flowers and unequal leaves." Satyrion Dens canimis, 

 Hennodactylus and Pscndohcrinodactylus are given as sjaionyms 

 used in different regions. " * * * Flowers either purple-red or 

 white, or purple and white mixed." 



Plunkenetius (Phytographia, 1692,3: 130). 

 ''Dens caninns, flowers yellow, Virginianus." * 

 Salmon's Herbal, 17 10. 



"Dogs tooth * * * the same as 'satyrion having red cortex 

 on the root,' in Dioscorides, lib. 3, ch. 144." Three color forms 

 are described having white, red and purple flowers respectively. 

 Roberto Morrison, of London, in his Plantarum Historia 

 Oxonienis, 171 5, page 343, says that the name " Dens canis is 

 from the shape of the oblong tuberous root imitating the figure of 

 a dog's tooth, the name is good." " It has a capsule of three dis- 

 tinct valves. * * * When the flower is red the leaves are red 

 spotted, when white the spots are milky." 



Gronovius (Flora Virginica, 1739, 151, ist edition). 

 '' Erytlwoniuni, leaves oval or oblong, glabrous, dark -spotted, 

 flowers yellow." t (Cited in Linnaeus Spec. PI. 1753, as var. /-, 

 under E. Deus-canis). 



Gronovius' Flore Virginia,' Lugdonum, 1762, 51 (2d edi- 

 tion), contains a description of our native species. " Erythroninm 

 with ovate oblong leaves, smooth, dark-spotted. Dens-caninus 

 agiiatalis, flower yellow, pendulous, leaves ovate-oblong, prostrate, 

 two upon a stalk, glabrous, dark -spotted. Blooming toward the 

 end of March." 



The reproduction by offshoots or runners, is mentioned in 

 Miller's Gardener's Dictionary, London, 1754, Vol. I., " Dens-canis 

 — Dog's tooth. * * * These plants are propagated by seeds, as 



* Virginia mis is italicized, as are authors cited on the same page, but here it may 

 be a typographical error for a reference to Virginia, since the European form has purple 

 or red flowers. 



fThis is probably the first description of the American species; especially in- 

 teresting, as it has the modern genus name. See previous note.
