water Gate) and about Sandown, in abundance,"' Mr. W. D. Snooke 

 in Fl. Vect. !!! 



Lemna minor. In almost every ditch, pool or plash of stagnant 

 water, whether clear or otherwise, throughout the county and Isle of 

 Wight. 



Lemna polyrhiza. In clear, stagnant water of pools and ditches, 

 &c. Abundant in marsh-ditches between Yarbridge and Yaverland, as 

 well as in other parts of Sandown Level. Ditches in Easton Marsh, 

 Freshwater Gate. Near Petersfield, and common probably through- 

 out the county. 



Lemna gibbet. In standing water; rare? In a small pond near 

 Yafford farm, Isle of Wight, with L. minor, Oct. 1845. I found it 

 some years ago in a ditch near Lymington, with Hydrodictyon irtri- 

 culatum. Mantling a pool close to Chapel farm, Oakhanger, near 

 Selborne, Sept. 1848. Probably not uncommon in the county. 



The following list of Hampshire Potamogetons falls, I am con- 

 vinced, considerably short of the actual number existing in the county. 

 In the Isle of Wight their amount, like that of other aquatic plants, 

 is extremely limited, and the opportunities have hitherto been few of 

 extending my acquaintance with the species of the mainland. 



Potamogeton natans. In ponds, ditches and slow streams ; fre- 

 quent. 



Potamogetun oblongus. In wet ditches, on bogs, and marshy spots 

 or plashes on heaths and commons ; frequent, I think, in the Tsle of 

 Wight, and perhaps equally so over the whole county. On Lake and 

 Blackpan Commons. Bog at Cockleton, near W. Cowes, &c. 



Potamogeton plantaginens. In similar places with the last; rare? 

 It has not occurred to me in the Isle of Wight. Titcbfield Common, 

 in profusion, Mr. W. L. Notcutt ! 



Potamogeton lucens. In ponds and ditches ; probably common 

 throughout the county. Marsh-ditches at Sandown. Pond at Holy 

 Water, Wolmer Forest! 



Potamogeton perfoliatus. Ponds, lakes, streams, &c. ; rare ? Not 

 found in the Isle of Wight, nor have I myself yet seen Hampshire 

 specimens. " A very common species in Surrey and the neighbour- 

 ing parts of Hants," Mr. W. W. Reeves (in litt. 1848). 



Potamogeton crispus. In ditches, pools, &c. ; common probably 

 throughout the county. Abundant in the marsh-ditches at Easton, 

 Freshwater Gate, and in those at Sandown. Pond at the brick-kiln, 

 Bembridge, Dr. T. Bell Salter. 



Potamogeton pusillus. In ditches and other stagnant water, either
