66 ENGLISH BOTANY. 
Kent, Essex, Cambridge, Suffolk, &c., but apparently less abundant 
in the north, although Mr. Norman first noticed it at Seaham in 
Durham. I have not seen Irish specimens, but have found it at North 
Berwick and Haddington. 
England, Scotland. Annual. Late Summer, Autumn. 
Stems 3 inches to 1 foot long, usually prostrate, and with very 
short internodes. The leaves, especially at the extremity of the 
branches, are quite crowded together, the longest not more than $ inch 
long, and frequently smaller. Flowers not more than ,'; inch long, 
green, with the segments white, tinged with green. The nut tapers 
more gradually than in the two preceding forms, but it is quite 
probable that its peculiarities are merely the consequence of the cir- 
cumstances of its growth. 
FORM IV.—Polygonum (aviculare) microspermum. Jord. 
P. microspermum, Jord. Bor. Fl. du Centr. de la Fr. Vol. II. p. 560, Norm. Le. 
p. 142. 
Stem slender, prostrate; the branches spreading or ascending. 
Leaves oblong or strapshaped-oblanccolate, about as long as the inter- 
nodes. Ochrew very short, brown, silvery white and at length 
laciniate at the apex. Perianth indistinctly veined, red, rarely white, 
very small. Nut rather longer than the perianth, dark chestnut, quite 
opaque. 
In sandy places. Apparently rare. Mr. Norman records it from 
Stockton-on-Tees, Durham; Mr. J. G. Baker has found it at Hartley 
in Northumberland; and I have specimens from the Rey. W. W. 
Newbould, labelled from “ Jersey,” and from Mr. H. C. Watson, col- 
lected between Weybridge town and railway station. 
England. Annual. Late Summer, Autumn. 
Stems very slender. Leaves } to $ inch long. Flowers solitary or 
in pairs. Perianth little more than 4), inch long, with the point of 
the nut projecting slightly beyond it. The nut itself not above 
=}; inch long, dark coloured, and very dim. 
As I have not seen this form alive, 1 am unable to say what colour 
its foliage may be, and I have seen too few specimens to venture to 
give any opinion as to its claims to be considered a subspecies, though 
its very small flowers and nuts may perhaps entitle it to be considered 
distinct from the other forms of P. aviculare.
