Acaulescent, quite hardy in England. Leaves thirty to forty 
in a dense rosette, narrow-lanceolate, reaching twelve to fifteen 
inches long, twelve to fifteen lines broad above the middle, 
permanently glaucous-green, similar to those of jilamentosa in 
texture, the face slightly concave throughout, all straight, the 
point not pungent, the edge slightly filiferous. Scape exceeding 
the leaves. Panicle oblong-lanceolate, two feet long, moderately 
close, with densely pubescent rachis and branches. Perianth 
eighteen to twenty-one lines deep, cream-coloured, tinged with 
green towards the base, broader than deep when expanded; both 
rows of segments oblong, the inner ones an inch broad. Pilaments

One of the smaller stemless species of Yucca, long since intro- 
duced to this country, but not often met with. After flowering 
the plant seems much exhausted, and the portion which flowers 
dies, generally leaving side shoots, which require two or more 
years before they have strength to produce flower-spikes. The 
figure is from a fine plant grown in the Castle Garden, Reigate.
