in shape, and the whole plant in color, as it is sometimes quite 

 green, and at others red. The calyx is not turned back so 

 much as in the last, and the petals are ovate in form and not 

 heart-shaped, as in the Common Sorrel.

WATER PLANTAIN. ALISMA. 



Plate 4, fig. 16. 

 COMMON WATER PLANTAIN. Alisma plantago. 



A delicate, upright, water plant, which bears all its leaves upon 

 long stalks, and rising from the root. Seldom more than one 

 flowering stem to a plant, and this throws off on the upper part 

 whirls of three or four branches, each furnished with a scale, 

 where it joins the main stem, and ending in a little whirl of 

 three or four stalked flowers, formed of three curiously-wrinkled 

 pink petals. Calyx of three leaves. Seeds several, joined 

 together in a ring. 

 O. S. Floating Water Plantain, and Less Water Plantain. 



CLASS 7. HEPTANDRIA. 



(Containing Plants with Seven Stamens.) 



But one native of Britain belongs to this class, called the 

 Winter Green, a very rare plant in England, and one by no 

 means constant in having seven stamens ; in truth, the number 

 seven is very unusual in the parts of plants. The Horse- 

 Chesnut belongs to this class, and so does the snow-white Calla, 

 and the lurid mottled Dragons ; but besides these there are 

 scarcely any foreign plants of interest.
