Uncertain and excluded species 



Echeveria discolor L.de Smet ; Morren, Belg. Hortic. 24 : 159. 1874. Said to be Mex- 

 ican, but it cannot be determined from the brief description. 



Echeveria farinulenta Lemaire, 111. Hortic. 11 : . sub pi. 392. 1864. {E. farinosa 

 Lemaire loc. cit. 10 : Misc. 83. 1863 : not Lindl. 1849.) Perhaps a species of Dudleya. 



Echeveria Funki I,.de Smet; De Vos, Belg. Hortic. 27: 169. 1877. Cannot be deter- 

 mined from the description. 



Echeveria sohrina A. Berger, Gartenflora 53: 206. 1904. Known to us only from the 

 discription . 



Echeveria spathulifolia I^.de Smet; Morren, Belg. Hortic. 24: 167. 1874. Probably 

 not an Echeveria. 



A large number of hybrid Echeverias have been produced in gardens, and described 

 under binomials, and many unpublished garden names for other species or hybrids exist.
