68 THE JOURNAL OF BOTANY 
LYTHRUM RIVULARE Woop & Evans. 
By Dr. Emit Korune. 
In the Journal of Botany for 1901 (p. 172) is a cnoree of 
Lythrum rivulare Woo vans, compared with L. sagittefolium 
Son ese two species are said to be tetrandrous, but. L, sagitte- 
folium i is octandrous, and Sas my oa aha trimorphous flowers. It 
is not a Lythrum, but a Nesea. The two species ought to have been 
compared with the deseriptions of all the Neswas of the section 
Neneettat an contained in my monograph of the genus, and in 
subsequent papers published by me in different periodicals. Bight 
species belonging to the section 1 Walcarsasir um are known to-day, 
and may be disposed as follows
