Tin- natural order of this plant is uncertain. It has a ringent 

 corolla, termite leaves, a simple bristly pubescence, and is be- 

 sprinkled with resinous dots. 



113. Hexandria : In this order, are placed those 

 diadelphous plants which bear flowers with six stamens. 



There are only two genera of this order; viz. saraca, and fu- 

 maria or fumitory, of which last, some British species are very 

 common. 



114. Octandria: Comprehending such plants of the 

 class, as have flowers with eight stamens. 



The extensive genus polygala or milk-wort, and a few others, 

 compose the order in question. The polygala vulgaris or common 

 milk-wort, is a frequent, but very beautiful little plant. 



115. Decandria : This order brings together nume- 

 rous genera of plants characterized with the features of 

 the class, and here arranged because their flowers have 

 ten stamens. 



This, as we have observed is a copious order, and the species 

 belonging to a number of its genera, are very numerous. The most 

 common genera of plants we can mention, are the broom, furze, rest- 

 harrow, kidney-vetch, lupine, kidney-bean, pea, bitter-vetch, vetch, 

 lathyrns, tare, chick-pea, milk-vetch, dhalia, trefoil, bird's-foot- 

 trefoil, and many others. Among these and other genera, we find 

 numerous well-known species, such as the petty-whin, scarlet 

 runner, sweet-pea, tanpier-pea, everlast.ing-pea, santfoin, lentil, 

 laburnum, wild-liquorice, melilot, Dutch clover, and common clover.
