large, and obtusé. The flowers and fruits are disposed as in 
X, strumarium ; but the fruits are generally solitary ; they are 
half an inch long, nearly cylindrical obtuse, with the two beaks 
scarcely perceptible arid bent in, covered with short, thick and 
rough-thorns, rather soft, and not uncinate. The whole plant 
has a peculiar smell, not unpleasant, somewhat between the 
camphorate and gravulent odour, but weaker than in Conysa@ 
camphorata, &c. 
History. ‘This plant grows of Long-Island, near the sea- 
shore and marshes. I have found it common near Bath, on the 
downs, and in New-J ersey, near Bergen and Powles-Hook, on 
the margin of marshy meadows. According to Dr. Muhlen- 
berg, it grows also in Pennsylvania; Messrs. Torrey and Le- 
conte found it on the Island of New-York; and by Morison 
and Decandolle’s account, it is found as far north as Canada. 
It blossoms in August and September, but the fruit remains on 
the plant till the severe frosts of December. 
Observations. ‘This species differs from the X. macrocarpon 
of Decandolle, by having smaller fruits, without horns, and 
Whose thorns are neither hooked nor hispid ; by not having an 
angular stem, but a round, spotted one, and by its leaves being 
broader, and not serrate, &c. Nearly all those differences exist 
between itand the X. orientale of Asia, which has not yet been 
isolated from the X. macrocarpon. The X, edrinatum differs 
from this by having oval fruits, with aggregated, echinate, and 
heoked thorns; and the X. strumarium, by having cordate hir- 
Sute leaves, the fruits aggregated, with hooked thorns and horn- 
ed tops. The X. spinosum, and X. frulicoswm, are so totally 
different that they need not be compared.
