EPHEMERUM STELLATUM IN BRITAIN. 
By W. E. Nicuotson. 
(Puate 442.) 
E sandy clay soil in the neighbourhood of Crowborough, in 
the north of the county of Sussex, is particularly rich in Ephemera, 
and I have already gathered there Z. serratum Hpe. in abun 
with the var. angustifolia Bry. Hur., EF. sessile Rab, and the var. 
brevifolium Schp., and Nanomitrium (Hphemerum) tenerum Lindb. 
a 
Li. sessile var. brevifolium, but examination with a lens showed that 
less. 
, Kent, mounted in a micro-slide with a form of 
fi. serratum, with which it was growing, without exhibiting any 
at my disposal, s much struck by the apparent resemblance of 
my plant to . stellatum Philib., as described by Boulay (Muscinées 
de la France, , an r. Dixon, to whom I sent specimens, 
8 * 
which he was good enough to examine and compare with the 
original material. His report was that my plant differed but little 
panulate, as in the late Prof. Philibert’s plant. have found, 
however, that in the smaller barren stems of the Crowborough 
plant the leaves are quite as stellate in arrangement as in the 
stems which Mons. Husnot sent me; and, with regard to the 
calyptra, that when uninjured it is campanulate, and the cucullate 
appearance noticed by Mons. Husnot was no doubt due to the fact 
that the mounted stems which I had sent him had been subjected 
to considerable pressure, which had split the calyptra on one side, 
living it a cucullate appearance. : ec) 
he following diagnosis is practically a translation of the original 
one given by the late Prof. Philibert in La Revue Bryologique for 
1879, p. 68 :—
