20 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
invariably grows near the edge of the loch, in comparatively shallow 
water. The specimens gathered in 1878 were growing in water less 
than one foot deep, in 1879 about two feet. I have seen type hetero- 
phyllus in deeper water at Coldingham Loch, Berwick. P. pralongus 
and P. crispus, both of which occur in Cauldshiels Loch, prefer the 
deeper parts, as neither are visible from the side, but very long 
specimens of both are frequently washed ashore.” 
Potamogeion pralongus , Wulf.? Plentiful in the canal at Navan, 
County Meath, growing with C Enanthe fluviatilis , Colem, 15th Sep- 
tember, 1879. Sent by Mr. Charles Bailey. Not recorded for district 
5 in Cybele Hibernica. Professor Babington writes: “I much doubt 
this, the tips of the leaves are quite different. Is it not detipiensV' This 
is the locality where Mr. Bailey collected P. decipiens , Nolte, as 
recorded in Ex. Club Report for 1879, p. 15. In the River Boyne, 
which runs parallel with the canal at this point, occurs the P. Lonchitis , 
Tucker., but he failed to collect any, as the river was in flood; never- 
theless, green plants were found drifted on to the overhanging bushes. 
Potamogeton mucronatus , Schrad. Mr. W. H. Beeby sends this 
species from the Great Pond, Gatton Park, Surrey, 4th August, 1879. 
Dr. Boswell says it is a good sample of the plant, if it had not been 
without fruit. 
Potamogeton pedinatus , L. Mr. W. B. Waterfall sends this 
from brackish ponds and ditches, Shirehampton Marshes, Bristol, 
West Gloucestershire, 4th August, 1879. Dr. Boswell and Mr. T. R. 
Archer Briggs name it var. scoparius. 
Ruppia spiralis, Hartm. Dr. R. L. Baker sends a supply from 
Walton-on-the-Naze, Essex, June, 1879. Mr. J. Groves sends typical 
specimens from a saltmarsh ditch near Newton, Isle of Wight, 17th 
September, 1879. Professor Babington thinks the plants from both 
stations “are spiralis , i.e., marina , L.” 
Alisma PI ant ago, Linn., b. lanceolatum. From the margin of a 
stream, Ashley Down, Bristol, West Gloucestershire, July, 1879. 
Sent by Mr. W. B. Waterfall. Kew specimens were noticed in the 
Exchange Club Report, 1868, p. 15. 
Spiranthes as tin al is, Rich. Mr. A. Bennett sends this from 
near Lyndhurst, on the Christchurch road, but not the original locality; 
collected by Mr. D. Marquand, August, 1879. See Exchange Club 
Report, 1872-4, p. 42. 
Allium Ampeloprasum , L. var. b., bulbiferum. Sent by Mr. Jas. 
Cunnack from Poltesco, near the Lizard, August, 1879. The station 
seems to be the same as that recorded in the E. C. Report, 1872-4, 
p. 42, but as many of the specimens had heads with projecting 
pedicels, selected examples, with this character, were submitted to 
Prof. Babington and Dr. Boswell. Prof. Babington writes : — “ I 
consider this to be Allium Babingtonii , which seems to me, as it did 
to Mr. Borrer, quite a distinct species. I have had it and A. 
Ampeloprasum in cultivation for . many years. I have only seen 
A. Ampeloprasum with head bulbs from Guernsey : no A. Ampeloprasum 
at all from Cornwall.” Dr. Boswell would also name the plant 
submitted to him Babingtonii. 
Luzula pilosa , Willd., b. Borreri , Woods. Sent by Rev. 
Augustin Ley from the woods Wyndcliff, Monmouthshire, 25th June,
