than vertically. Yet the Flowers and Seeds themfelves 
are perfectly the fame as in the other. This fecond 
Kind grows plentifully on the high rocky Grounds 
about Campecby, where I gathered it in Perfection in 
the Beginning of November , 1730. 
I cannot guefs why Father Plumier has called this 
a monopetalous Plant , for that which he calls the 
Pet alum , and I the Placenta , is of a green Colour, 
and (which is of more Confequence) fuftains the 
Seeds when ripe, and never envelops the Organs of 
Generation when young •, fo that I think it can by no 
Means be called a Petalum, nor even properly a Ca- 
lix, and therefore I have given it the Name of Placen- 
ta, whofe Office it certainly performs. • 
I have not been able to obferve exaCtly the Structure 
of the Organs of Generation, becaufe of their excef- 
five Smallnefs; but they appear to the naked Eye as 
they are reprefented in the Figures I have given of 
them, and in Plum. N.G. Tab. 8. Th t Dor ft eni a 
Sphondy'lii folio Dentarhe radice, of Plumier , difv 
fers from both of mine ; for in his Drawings done 
by Order of the late King of France , whereof I have 
feen a Copy in the Collection of the late Dr. Sberard , 
the Leaves are reprefented ferrated, the Placenta qua- 
drangular, and the Roots confifting of feveral Knobs 
tied together Lengthways^ From which laft Particu- 
lar, lam perfwaded that the Root of that Species is 
the Drakena Radix, mentioned by Clu/ius in his 
Exoticks , pag. 83.
