SHORT NOTES. 
Frora or Lancasuire. — We are pleased to learn that an i 
portant gap in our local Floras i is likely to be filled up before aca: 
Mr. J. C. Melvill has undertaken to collect material for a Flora of 
Lancashire, and will be glad to receive lists or other information 
from those aft with the botany of any part of the county. 
Ne or PoTaMoGETon. oa ‘Scottish Naturalist’ for 
July contains the following description 
‘‘ Potamogeton pusillus L., var. Sturrock kit A. Bennett.—Stem 
) 2 in. lo 
much branched, 18 in. to 8 ft. long; leaves 0 long, 
broad, with the secondary veins indistinct. " Stipules 4 in,, 
blunt. Peduncles 1 in. to 24 in. lon ike } in., very sparingly 
ng; spl 
flowered ; fas io thick. A very elegant subspecies of pusillus L., 
with somewhat the habit of obtusifolius M.& K. Quite distinct 
from arifthing seen from Europe or N. America” (p. 28). 
** Potamogeton Seek Lis; a? rigidus A. Bennett.—Plant rigid, 
fragile, leaves rigid, o 24 in. Tou acuminate, strongly 
1-nerved, with two Sainte nerves in eke of syn leaves; stipules 
long, eget peduncles 1 in. long; spike } in. long ; fruit slightly 
smaller than in typical pusillus, ind less oitintee 4 the back. 
A eealener form of suntas, gathered by Dr. Trail from the 
Loch of Stennis, Orkney, August, 1876. It has much the aspect 
of P. rutilus Wolfgang, but differs by its elongated internodes, 
broader leaves, stipules, and fruit”’ (p. 25). 
Potyroprum Dryopreris anp P. Ropsrtianum iw Bu 
June the Rev. A. Robertson ae Mr. ae were botanising in 
South Oxfordshire, and in a small spinney on the borders of the 
county gathered some acai ns of the oak ies. As they were 
not certain as to the exact rao it was found in, being unprovided 
an ordnance an I went over to Princes Risborough and 
walked to Chinnor, and after some time found the fern in a sm 
spinney, locally known as Bollard’s Wood, which actually forms the 
border of the county, the wood being just in B eur Ei amshire. The 
fern i is plentiful, but restricted to a small space, and is achat 
with L. spinulosa and L. dilatata. It is apparently absent from the 
tkez neighbouring woe. Tunley Wood, Pyrola minor and Hordeum 
sylvaticum plentifully o urring. P. Robertianum is given for Bucks 
in ‘ Top. Bot., on the aithority of a specimen seen by Mr. Britten ; 
but the above is the only record of Dryopteris for Central and 
Southern England, the Ph stations being West Gloucester and 
Staffordshire —G. C. Dru 
Ss a pendant to Mr. Dies’ s note, it may be worth while to 
give details as to the single instance known of the occurrence of 
m in Buckinghamshire. About 1863 Mr. H. Ullyett 
(now of Folkestone) pon two specimens in King’s Wood, close to 
Hazlemere, a village near High Wycombe. ar most careful 
search on his part, an iF vabpea tilly on mine, failed to discover 
another specimen ; nor have I heard of its morals been found there
