Estheria minuta

By L. RICHARDSON, P.G.S. 
URINGr the past ten years (1891-1901) several 
anthers have recorded the organic associations of 
Esther ia minuta var. Brodieana. At Pylle Hill the late 
Edward Wilson, E.Gr.S., found that Estherian in his bed 
“ 1 ” associated with Naiadita and two species of Dar- 
ivinula ; but it is in the immediate subjacent shales that 
the remains of the Lycopodiacean are most abundantd Mr. 
W. H. Wickes^ records a similar association at a section in 
New Clifton, but here with the addition of marine lamelli- 
branchs. Miss I. B. J. Sollas described — on the authority 
of Prof. J. Phillips — the plant Naiadita as being in associa- 
tion with the same Estherian at Wainlode and Garden 
Cliffs. In the discussion which followed the reading of this 
communication, it was observed that it would be of interest 
to know whether this plant grew in fresh or salt water.
