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- 
Sera 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 
Carritre,t who suggests its possible generic separability 
from Yucca, show that it then occurred further in gardens 
as Y. Parmentieri { and Y. Japonica. 
It has alsobeen grown as Dasylirion aloefolium,§ and the 
complication of its nomenclature is increased by the addi- 
tion of the genus Joezlia of Roezl (not of Regel) as 
synonymous with Y. jilifera,|| and this name and Lilia 
(sometimes also spelled Lilium) have been somewhat cur- 
rent in gardens and horticultural papers] for Y. Parmen- 
tieri, under which name, as stated above, Y. filifera has 
been cultivated, though Lilia regia, Lilium regium, Roez- 
lia regia, and Ff. bulbifera of gardens are properly syn- 
onymous with the real Y. Parmentieri, which is also known 
as Y.argyrophylla, Y. Toneliana, and Y. Pringlei, and
