 X E. TETRAGONO - PARviFLORUM, F. Schultz. E. iceissenhurgense, F. 

 Schultz, in Pollichia (1861% 106. E. adnafum xpariiflorum, Haussk. Mon. 

 Epilob. 105. Near Sunningwell in 1893. The E. parvijlorum parentage 

 is very marked, while the influence oi E. tetragonum is shown in the 

 toothing of the leaves, in the slightly decumbent limb of some of the 

 leaves, and in the lined stem. Another hybrid, in which the influence 

 of E. teiragonxmi is more apparent, occurred near Uffington in 1889. 

 Another plant from the same locality was fairly intermediate ; see an 

 interesting note by my friend, the Rev. E. S. Marshall, in Joiim. 

 Bot. (1891) 7.
