Ii8 White to Green and Brown Flowers 



WILLOW-LEAVED DOCK 



Rumex salicifolius. Buckwheat Family 



Stems: erect, ascending or spreading, simple or branched, grooved. 

 Leaves: lanceolate, acute at. both ends. Flowers: in dense clusters. 

 Fruit: the faces of the achenes concave, smooth, shining, winged. 



A large coarse plant growing several feet high, with a 

 strongly grooved stem, huge long-shaped bluish-green leaves 

 that are pointed at both ends, and panicles of green flowers 

 set in loose whorls near the apex of the stalks. These flow- 

 ers have no petals, but only a green six-parted calyx, the 

 three outer divisions of which remain unchanged in fruit, 

 while the three inner sepals develop into wings. The fruit 

 is dark red. 



Rumex Acetosa, or Common Sorrel, is a much smaller 

 plant, and has arrow-shaped leaves, and green flowers tinged 

 with red, which deepen in colour to a purple-red as the 

 season advances. The leaves and juicy stems are slightly 

 acid, and the root is very astringent, yielding an excellent 

 red dye. This is an introduced plant. 



Rumex Acetosella, or Field Sorrel, has a creeping root- 

 stock, and halberd-shaped leaves which are pointed at the 

 apex. The green flowers are tiny and grow in a loose 

 raceme. This plant flourishes in the poorest soil, and to- 

 wards the end of the summer turns a rich red colour. This 

 is an introduced plant. 



ALPINE BISTORT 



Polygonum viz'iparum. Buckwheat Family 



Stems: slender, simple. Leaves: ovate, subcordate, attenuate at 

 base; cauline leaves lanceolate. Flowers: raceme narrowly cylindric, 

 densely flowered, bearing a number of ovoid-conic bulblets at base.
