178 DISCOVERY OF EUPHORBIA PALUSTRIS .IN SUSSEX. 
It has been gathered also in the south of Scandinavia, but by the 
northern botanists is regarded as a variety only. Fries (Summa, p 
243) writes respecting it as follows: —“ Quamvis hee charactere foliorum 
admodum notabili polleat et statione in limo, seepe ad spicam usque 
inundata, florendique tempore serotino multis speciebus insignior 
videatur, tamen in loco natali, sensim magis magisque sicco, formis 
intermediis ind. montanam (i. e. flexuosa) ita directe abit ut nullibi 
transitus magis — Fries includes it in his ‘ Herbarium Nor- 
male,’ part 2. n. 73. Anderson figures it in his * Graminez Scan- 
dinaviz,’ plate 1s. tab. 143, and expresses entirely the same opinion 
of its relation to A. flexuosa. The accompanying drawing is made 
from one of Don's specimens. 
GOMPHONEMA IN CONJUGATION. 
Dr. Henry Carter informs Dr. Gray, that he has for several years, in 
the beginning of May, found Gomphonema in conjugation in a parti- 
cular spot at Budleigh Salterton, Devon, but that he cannot discover 
the adventitious sheaths upon the new frustules which are so evident 
under similar circumstances in Navicule, etc. 
DISCOVERY OF EUPHORBIA PALUSTRIS IN SUSSEX. 
In a walk with Mr. J. Edwards, of Ditchling, about four years ago, 
he pointed out to me what I then took to be a form of E. amyg- 
daloides; but in looking over my plants this spring, my attention was 
again attracted to it, and having some doubts of the correctuess of my 
original determination, I showed it to Mr. Baker, who recognized it 
as being Æ. palustris, which has hitherto only been found in the neigh- 
bourhood of Bath. It was found growing with E. amygdaloides, in a 
wood called Blackbrook, in the parish of Westmeston.
