Flora of Hants. 
Potamogeton fiabellatus , Bab. River Wey, Guildford, Surrey. I 
send further specimens from the old locality. I have not seen an 
original specimen, or one confirmed by Prof. Babington, but this has 
always been accepted by Mr. Arthur Bennett ; at least he has made 
no objection to the name. — W. H, Beeby. “ I am far from sure of 
this being correct.” — C. C. Babington. 
Zannichellia macrosiemon. Pond, Redheugh, Gateshead, Durham,

account of this interesting plant, of which Mr. Bailey sends a large 
series of well-dried specimens, see “Journal of Botany,” 1884, p. 
305-333, where it is described under the name of N grami?iea, Delile, 
var. Delilei, Magnus. A reprint of Mr. Bailey’s paper was sent to

same locality by Dr. Fraser as L. albida. 
Juncus lamprocarpus x acutijlorus. Bog, Hedge Court, Millpond, 
Surrey, September 9th, 1883. See Report for 1882. Since sending 
to the Club, I have sent further specimens to Dr. Buchenau, calling 
his attention to the uniform sterility of the plant; he replies (22nd 
August, 1884,) “From the form of the perianth, and from your 
observations, probably = J. acutiflora x lanipro carpus. Interesting, 
as hybrids are rare in this order.” — W. H. Beeby. 
J. biglumis , L., Cam Chreag, Mid. Perth, August 21st, 1883. — 
W. R. Linton. Mr. Linton’s specimens must have been partly 
J triglumis , as Mr. Beeby writes that the one he received was the 
latter.
