than it does Brasenia. Further than this, the name Brasenia anti- 
qua was preoccupied at the time of its adoption by Dawson, a fact 
in regard to which he was apparently in ignorance (see Brasenta 
antiqua Newberry, desc. in Proc. U. S. Nat. Mus. 5: 514 (1882); 
undistributed plates, Cret. and Tert. Floras, p/. 68, fig. 7) and as 
Newberry’s specimen, consisting of stems and fruit only, is from 
the eocene tertiary, there -is little likelihood that the two are 
referable to the same species. 
Under the circumstances I would propose that Dawson’s plant 
be renamed, in accordance with recently adopted rules of nomen- 
clature, as follows: Nelumbo Dawsoni — Brasenia antiqua Dawson 
(1885), not Brasenia antigua Newberry (1882). 
By this means Dawson’s name may still be retained in connec- 
tion with the plant which he unwittingly described under a name 
already preoccupied. 
Finally, it may perhaps not be amiss to call attention to the 
Seographical distribution of the living species. Only two are re- 
cognized, viz.: NV. nucifera Gaertn., ranging from the Caspian Sea 
to Japan and thence southward to Australia, and WV. /utea (Willd.) 
Pers., ranging from Kansas and Missouri to Lake Erie and thence 
southward to the West Indies. It is another example of the sim- 
ilarity between the floras of Eastern Asia and Eastern North - 
America which has so often attracted the attention of those who
