Y. rLacorpa (Haworth, Pl. Suc. Suppl. p. 84). Acaulis, foliis 20— 
80 dense rosulatis anguste lanceolatis arundinaceo-coriaceis 
viridibus junioribus glauco tinctis 18—21 poll, longis 15—18 
lin. latis planiusculis apice haud pungentibus marginibus 
copiose filiferis exterioribus cite recurvatis, perianthii late 
campanulati 18—21 lin. longi segmentis oblongis, filamentis 
puberulis apice incrassatis uncinatis ovario ampulleformi 
sequilongis, stigmatibus ligulatis apice emarginatis ovario 
duplo brevioribus.—Bot. Reg. t. 1895. Kunth, Enum. iv. 272. 
A native of the Southern United States. 
Acaulescent, quite hardy in England. Leaves twenty to thirty 
in a dense rosette, lanceolate, eighteen to twenty-one inches long, 
fifteen to eighteen lines broad above the middle, narrowed 
gradually to half an inch broad above the base, thinner in 
texture than those of filamentosa, slightly glaucous when young, 
the face flattened except near the non-pungent point, the edge 
detaching copious gray threads, many of the outer ones becoming 
abruptly decurved, so that the rosette has an irregular untidy 
appearance. Scape many times exceeding the leaves. Panicle 
oblong-lanceolate, a yard long, not very close. Perianth eighteen 
to twenty-one lines long, cream-coloured, tinged with green 
towards the base, broader than deep when expanded; both sets 
of segments oblong, the inner ones nine to ten lines broad. Fila- 
ments nine to ten lines long, curved and thickened at the point, 
equalling the flask-shaped ovary. Stigmas ligulate, emarginate 
at the tip, half as long as the ovary. 
In a broad sense both this and the preceding are evidently 
only varieties of filamentosa. 
Tas. 323.—1, whole plant, reduced. 2, leaf; 3, branch with flower; 
4, stamens and pistil: all natural size.—J. G. B.
