A Botanical defcription of the PopoPHYLLUM DrpHyL- 
LUM of Linneus, in a Letter to CHARLES PETER 
Tuunserc,M. D. Knight of the Order of Wafa, Pro- 
Seffor of Medicine and Botany in the Univerfity of Up/al, 
ere, CC. 
DEAR SIR, 
Read May  N the time of Tournefort, and for many years 
18, 1792. after his death, the Anapodophyllion of this 
great botanift was confidered as a genus of which there 
was known but one fpecies, viz. the Anapodophyllon Cana- 
denfe Morini. When the name of this plant was after- 
wards altered, by Linnzus, to that of Podophylium, he 
denominated the fpecies, which had been previoutly defcrib- 
ed by Tournefort, by Catefby, by Mentzelius, and by fome 
other botanifts, pe/tatum, from the target-fhape of the 
leaves. 
In the firft edition of the Speczes Plantarum, thisis the 
only fpecies of Podophyllum which we find mentioned, or 
defcribed. In the fecond edition, which was publifhed in 
1762, we find another {pecies, under the name of diphyl- 
lum, The two plants now ftand oppofed to each other, in 
the following concife characters: viz. 
1. PoDOPHYLLUM peltatum foliis peltatis palmatis, and 
2. PopopHyLLuM diphyllum foliis binatis, femicordatis. 
Thefe charaéters have been preferved in all the fubfequent 
editions of the Species Plantarum and SyftemaVegetabilium 
that I have feen.
