superantia, stylo breviora, stigma crassum. This 
very remarkable plant is only known by Ruiz's 
specimen in Mr. Lambert’s Herbarium. It is the 
only one-flowered Hymenocallis known, and in 
other respects it approximates to the Pancratium 
of the Eastern Continent ; so that, from the mere 
examination of the dry specimen, I do not feel 
quite confident of its genus. It is barely possible, 
though not probable, that the Asiatic form of 
Pancratium may manifest itself on the heights of 
Quito. The two-flowered Hym. rotata is the species 
most nearly allied to it, though very inferior in the 
size of its cup. I much lament the impossibility 
of obtaining any knowledge of its fruit, and I wish 
to call the attention of collectors to this plant, and 
especially to its seeds. I am at a loss to imagine 
how it could have been supposed in Germany that 
this plant was allied to Urceolina pendula : it is 
very remote from it indeed. — Leaves 13 inches, 
attenuated at both ends, -|ths wide; scape 7 inches, 
one-flowered ; germen sessile, f long ; tube 4f, 
limb 3f , cup 2 inches long, perhaps 2^ wide ; fila- 
ments about -|ths longer than the cup, shorter than 
the style; stigma thick.

Maximilian mentions a white Amaryllis on the 
banks of the Rio Grande, which is probably this 
plant, which has a scape from 2 to 4 feet high, and 
15 or 20 sweet flowers. No Crinum is known to 
inhabit America with a scape bearing so many 
flowers. 
Choretis. — Filaments attached to the upper part of 
the anther in a prominent callosity ; anthers recurved 
at top and bottom. — Seeds short, oblong, i. e. inter- 
mediate in form between those of Hymenocallis and 
Ismene, shorter than the former, but not round, as in
