OBSERVATIONS ON ZAMIA INTEGRIFOLIA. 23 
have served in Florida, (particularly Dr. Abadie,) who 
have not only communicated to me information, but have also 
supplied me with specimens. To these gentlemen was the fe- 
culent substance not only familiar, as it afforded them an arti- 
cle of food, but also the plant from which it was procured. 
The plant from which Florida Arrow Root is derived is the 
Zamia integrifolia of botanists; a plant which for a long 
time has been known and described. Under the name of Zamia 
pumila,we find it noticed in the " Species Plantarum," of Lin- 
naeus; in the "Species Plantarum," by Willdenow, however, it 
is described by the title of Z. integrifolia, witti the citation of 
Z. pumila as a synonym. Willdenow refers to the Hortus 
kewensis of tfliton, who appears to have drawn up his ac- 
count of it from living specimens, as it w T as introduced by 
John Ellis, Esq., in 1768, and cultivated in the hot houses of 
England. In Curtis 7 Botanical Magazine for 1816, there 
is given a description and figure of the plant; the female 
alone is there represented. In the same work is also present- 
ed the figure of another species, the Z. media, which would 
apppear to be hardly worthy of any other distinction than as 
a variety. The representation of the plant, however, had 
previously appeared in the "Icones" of Jaquin. 
From Endlicher's " Genera plant arum" which is now 
regarded of the highest authority, we have obtained the fol- 
lowing generic description.
