class monaxdria. — Containing two orders. 
ORDER MONOGYNIA. 
Ill this country wc have very few examples of plants of this 
class: the Hippuris an aquatic plant is sometimes found in stag-* 
nant water ; it is the most simple of all perfect* flowers, having 
neither calyx nor corolla, and but 1 stamen, 1 pistil, and 1 seed. 
The germ in maturing, hardens into a naked seed without any 
kind of appendages. The genus Hippuris contains but one spe- 
cies. It belongs to the natural order Inundatae, signifying grow- 
ing in water. 
The Salicornia or Samphire is found in salt marshes near the 
sea coast ; it grows also at the Onondaga salt-springs.f In 
Europe it is collected in large quantities, dried in the sun and 
then burnt ; the ashes are collected and used in the manufac- 
ture of soda. 
Shakspeare speaks of this plant in describing the precipice of 
Dover, which overhangs the sea. 
“ How fearful, 
And dizzy ’tis to cast one’s eyes so low 1 
Half way down, 
Hangs one that gathers Samphire : dreadful trade !” 
Although the plants of this class are so very limited in north- 
ern countries, some of the most valuable vegetable productions 
of the tropical regions are found here ; as the Arrow root so 
useful tq the sick as a nutritious substance ; the Turmeric re- 
* Although so destitute of other organs, it is called perfect because it has 
stamens and pistils,
