retained for the garden one seed only has germinated, so that 
the species is probably of extreme rarity. It is a handsomer 
looking plant than Garrya elliptica, with oval laurel-like 
leaves, which are covered with down on the under side. 
According to Mr. Hartweg it grows on the mountains in the 
northern provinces of Mexico. He found it near Guanaxuato 
a shrub from fifteen to eighteen feet high ; but at Anganguco 
it formed a tree with a trunk two feet in diameter.

A small stemless plant, with tuberous roots like those of 
the common Arum, purple-stalked pedate leaves, and a pink 
or purple spathe from five to six inches long. It will pro- 
bably form a greenhouse herbaceous plant. Mr. Hartweg 
found it in shady woods near Morelia flowering in July, and 
sent it to the Horticultural Society, with whom it has been 
raised.

There is a good figure of this plant in the Floral Cabinet, 
Vol. 2. p. 51, and an interesting account of its peculiar habits 
at p. 47 of the same volume, from which it appears that the 
species lives in the deep muddy swamps in the neighbourhood 
of Mobile, which it studs with its beautiful snow-white starry 
blossoms, and perfumes with its fragrance, at a time when, 
from the softness of the mud such places are unvisited except 
by the most adventurous travellers. It is stated that the 
bulbs frequently lie imbedded two feet in the mud, so that 
the entire plant is full four feet high, and the collector, in 
his efforts to obtain the bulbs was frequently sunk above 
his middle in this unpleasant bath. In the summer months, 
when such swamps become hard, the plant dies down and dis- 
appears, its very site being covered with other vegetation. 
It is much to be regretted that in publishing an account 
of this fine plant the authors of the work in which it ap- 
peared should have stated it to be new, and named it Zsmene 
Knighti; a double error being thus committed, the plant not 
belonging to the genus Ismene; but to Hymenocallis, and not 
being a new species, but one long since published in Messrs. 
Loddiges’ Botanical Cabinet, t. 19, and in the Botanical 
Magazine, t. 827, under the name of Pancratium rotatum, by 
which it is well known in collections. These are the new
