Brasenia peitaia. Canada io Florida and Eastern Texas, 
ern Himalayas, Japan (jide Planchon), Eastern Australia. The 
only known species of the genus. ‘The other genus of this 
group, Cubomba, was once thought to furnish another case of 
great disjunction ; the original species inhabiting Cayenne and 
Brazil being long supposed to be identical with the species of 
the Southern United States. The latter I distinguished twenty 
years ago, Nae. by the form of the floating leaves, under the 
name of C. Carolinianu; but I should not be surprised if it 
were eventually reunited to C. aquatica.

as a pean species, having the impression that it was SUup- 
to have been wrongly introduced into the Flora of Great 
ritain. Hooker and Arnott, however, still retain it, although 
marking it as extinct. If it was really found indigenous in Seot- 
land, then it is (as Prof. Tuckerman has aptly remarked to me) an 
exact counterpart to Carex fulva, which was first detected in this 
country, and once gathered in Massachusetts, but never found
