North Hants, but not quite so luxuriant as the Twickenham 
plants, or as some of those plants. In turn, the Hants examples 
were more luxuriant in growth than specimens of so-labelled erecta, 
received from other counties ; and hardly separable from these last 
by any character other than that of size or vigour in growth. 
Dr. Syme would distinguish Hudson’s erecta from Babington’s 
deltoidea by the leaves “ wedge-shaped at the base, with the cusps 
ascending”. But Professor Babington’s figure of his prostrata 
(placed under deltoidea by Dr. Syme) shews us nearly such a leaf 
as described in the words quoted. Further observation of the living 
plants would thus seem to be needed.

63. PoLyGonacEsz. - 
Polygonum (amphibium) terrestre, Auct. ; 
Provinces all? More frequent than the aquatic form. 
Syn. 933. A state, rather than a variety; and yet so unlike the 
typical or floating form of the plant, that it would assuredly have 
been considered quite a distinct species, if it had been brought 
into herbaria from distant countries only. ‘In this instance, the 
more frequent state cannot well be held the typical one; and 
perhaps it becomes the more frequent only because the surface of 
our lands so much exceeds the surface of our waters. The ter- 
restrial stems are often flowerless.

from the type form “ even as a sub-species”; Eng. bot. vil. 77.

where about the neighbourhood of London; Dr. Boswell Syme, in 
Eng. bot. viii. 75. Not known to me.
