NOTES ON THE FLORA OF SUSSEX. 267 
doubt. The notes are headed “ ascertained " and ‘ doubtful” Sussex 
plants; and he observes under this, * The habitat, sandy coast about 
Thorney Islands, is doubtful," and Borrer says it was never found in 
the county. 
? Populus alba, L. Old trees occasionally met with in woods, but 
perhaps always planted. 
alix alba, L. It is doubtful whether the true alba is a native. 
? 8. Helix, L. “ Steyning, planted?" Herb. Borrer, is all I know 
about it. ' 
? S. acuminata, L. I know no station for this, perhaps only found 
in the willow-beds. 
? S. pentandra, L. May be expunged, I think, without any doubt. 
? Orchis fusca, Jacq. Another of Smith's “ doubtful" Sussex 
plants. 
? Fritillaria meleagris, L. Said to have been found in a meadow 
north of the church at Hurstpierpont, but it has not been found there 
of late, nor in any other part of the county. 
Colchicum autumnale, L. Not marked from Sussex in Watson’s 
SuppL, but in Borrer’s manuscript notes is the following station :— 
“In a meadow by Clay Lane, Storrington West Down; since lost.” 
Potamogeton filiformis. Watson gives this without a doubt, but the 
true P. filiformis of Nolte has not been found in the county; and P. 
peclinatus must have been the segregate species intended. 
? P. zosterifolius, Schum. ; (P) P. heterophyllus, Schreb., and (?) P. 
plantagineus, Ducr., are reported from the county, but on very 
questionable authority; and the late Mr. Borrer, in the * Phytologist ’ 
for 1854, expressed strong doubts as to their having been found. 
No well authenticated and particularized stations are on record, 
*Ruppia rostellata, Koch. I have this from East Sussex, and 
in Borrer's herbarium is a specimen from Ford in the western divi- 
sion, 
? Acorus Calamus, L. ‘In a pond on Duncton Common, probably 
planted,” Herb. Borrer; and I have seen it in a pond in Arundel 
Park, where it was doubtlessly planted also. 
* Agrostis Spica-venti, L. Southwick, Borrer’s manuscript notes ; 
and I have found it in cornfields about Clayton, ete. 
* Festuca arundinacea, Schreb. Found in many places near the sea. 
? Polypodium Dryopteris, L. No other record beside Moore’s 
“ Near Danny ” has reached me, and that Mr. Borrer doubted.
