Ismene Salis. ex Herb. An Appendix 45. 1821.
ISMENE.
Foliis annuis, semine rotundiore, tubo plus minus curvato, corona longiore,
filamentis brevioribus, superioribus tribus in coronam cernuis, tribus inferio-
ribus conniventibus et implexis, ab Hymenocallide discreta. Species.
. 1. Amancaes. Bot. Mag. 1224. Pancratium.
. 2. Calathinum. Bot. Reg. 215.
. 3. Nutans. Bot. Mag. 1561. P. Narcissiflorum. Jacquin.
Distinguished from Hymenocallis by annual leaves, rounder seeds, tube
more or less curved, longer cup, shorter filaments, of which the upper three
are bent downwards into the cup, and the lowest three conniving and cross-
ing each other. Species. * 1. Amancaes. - 2. Calathinum. - * 3. Nutans.-
Culture, &c. The only difference between the cultivation of Ismene and Hy-
menocallis, is, that the bulbs of Ismene require to be completely dry during
the winter, and will certainly perish if watered during the season of rest.
Amancaes was separated from Pancratium by Mr. Salisbury (Hort. Trans.),
under the name Ismene, without any statement of the point in which it dif-
fered. Nutans agrees with Amancaes in the curvature of the tube; Calathi-
num, which in foliage is closely allied to Amancaes, has the tube much
straighter, but a little bent. The seeds of Amancaes, ripened at Mr. Grif-
fin's, burst the capsule, as those of Hymenocallis generally do, but they
were rounder and smoother, and, if I recollect right, the scape was erect
and not bent to ground, like that of Himenocallis. The seed of Nutans,
represented by Jacquin, agrees in form with that of Amancaes. The cup of
Ismene is not prolonged beyond the insertion of the filaments, as in Liriope,
except in the intervals.
