Y. FILAMENTOSA var. GRANDIFLORA (Baker). Acaulis foliis 80—40 
dense rosulatis anguste lanceolatis 18—21 poll. longis 18—21 
lin. latis arundinaceo-coriaceis glauco-viridibus apice haud 
pungentibus nullis recurvatis marginibus copiose filiferis, peri- 
anthu albi oblongo-campanulati 23—38 poll. longi segmentis 
omnibus oblongo-lanceolatis, filamentis puberulis apice incras- 
satis uncinatis ovario ampulleformi equilongis, stigmatibus

A native of the Southern United States. 
Acaulescent, quite hardy in England. Leaves narrow-lanceolate, 
thirty to forty in a dense rosette, eighteen to twenty-one inches 
long, eighteen to twenty-one lines broad above the middle, nar- 
rowed to half an inch above the base, similar in texture, point 
and edge, to those of the type, very glaucous when young. Panicle 
laxer than in the type, when well developed reaching four or five 
feet in length by a foot and a half in breadth. Perianth similar 
in colour to that of the type, two and a half to three inches deep ; 
both rows of segments oblong-lanceolate, narrowed gradually from 
below the middle to an acute point, the outer ones ten to twelve 
lines broad. Filaments and ovary as in the type, but the stigmas 
considerably longer in proportion. 
The handsomest form of the jilamentosa group.

flowers; 4, stamens and pistil: all natural size. 5, pistil; 6, stamen; 
8, horizontal section of ovary: all magnified.—J. G. B. 
This variety of Yucca jilamentosa appears distinct from the 
usual form, being larger in all its parts, and producing a 
handsome effect. I have had it in cultivation for several years, 
and received it as Yucca filamentosa. Its history is unknown to 
me. For treatment see observations on culture, &c., Tab. 313.
