Y. enstrouta (Hort.) Breviter caulescens, foliis 35—40 densis 
anguste lanceolatis 2—23 pedes longis medio 15—18 lin. latis 
glauco-viridibus facie prorsus concayvis apice pungentibus 
nullis recurvatis marginibus integris brunneo-lineatis, peri- 
anthii globoso-campanulati 18—21 lin. longi segmentis ob- 
longis dorso purpureo tinctis duplo longioribus quam latis, 
filamentis puberulis apice incrassatis uncinatis ovario ampul-

Probably a native of Mexico. 
Not hardy in the South of England. Stem a foot below the 
leaves in the specimen drawn, much swollen at the base. Leaves 
thirty-five to forty, spread over about a foot of the stem, narrow- 
lanceolate, reaching two to two and a half feet long, fifteen to 
eighteen lines broad at the middle, narrowed gradually upwards 
to a brown pungent point, and downwards to half an inch above 
the dilated base, pale glaucous-green, similar to those of gloriosa 
in texture, the face more or less concave throughout, not at all 
plicate, the edge entire, marked with a distinct brown line. Scape 
rather shorter than the leaves. Panicle oblong-lanceolate, two 
feet long, the lower pedicels fifteen to eighteen lines long. 
Perianth globoso-campanulate, cream-white, faintly tinged on 
the outside with red, eighteen to twenty-one lines long; both 
the imner and outer divisions oblong, about half as broad as 
long. Filaments ten to eleven lines long, puberulent, hooked 
and thickened at the apex, equalling the flask-shaped ovary. 
Stigmas ligulate, emarginate at the apex, one-third as long as 
the ovary.
