THE YUCCEAE. 105 



in connection with these provisional species he mentions the 

 Thurber material as representing still another, but without 

 giving it a name. 



Both the Gregg and Thurber specimens in 1873 were 

 unmistakably referred to his Y. baccata australis by Dr. 

 Engelmann, who suggests as possible synonyms the group 

 of provisional species of Baker and the undescribed Y. fili- 

 fera of gardens. 



In 1876, one of the plants raised from Roezl's Mexican 

 seed flowered near Hyeres, France, and was figured under 

 its garden name, Y. filifera, by Chabaud, who adds 

 Y. albospica* (which appears in large part to be Y. con- 

 stricta) and Y. canaliculata (which is properly a form of 

 Y. Treculeana) as synonyms. Accompanying notes by 

 Carriere,t who suggests its possible generic separability 

 from Yucca, show that it then occurred further in garden* 

 as Y. Parmentieri \ and Y. Japonica. 



It has also been grown as Dasylirion aloefolium^ and the 

 complication of its nomenclature is increased by the addi- 

 tion of the genus Roezlia of Roezl (not of Regel) as 

 synonymous with Y. Jilifera,\\ and this name and Lilies 

 (sometimes also spelled Liliurn) have been somewhat cur- 

 rent in gardens and horticultural papersU for Y. Parmen- 

 tieri , under which name, as stated above, Y. filifera has 

 been cultivated, though Lilia regia, Lilium regium, Roez- 

 lia regia, and R. bulbifera of gardens are properly syn- 

 onymous with the real Y. Parmentieri, which is also known 

 as Y. argyropTiylla, Y. Toneliana, and Y. Pringlei, and
