INTRODUCTION TO SOTANY.

Class VI.—HEXANDRIA.Plants whose flowers contain six stamens, as may be seen in theLilium, Lily, and many other such-like beautiful flowers, constitutebis class.

It may be noticed that the fifteenth class is composed of plantswhose flowers have the same number of stamens, but of differentlengths ; therefore a reference should be made to the characters of it,in which are laid down such rules as, with a little attention,will enableevery person to distinguish the one from the other *.

Class VII.—HEPTANDRIA.The seventh class is composed of such plants as have in their flowersseven stamens. The Horse Chesnut (JEsculus) and the Winter Green(Tricntalis) are of this class. And it may be remarked that it containsfewer plants than any other; indeed, the latter is the only one indige-nous to this country.

Class VIII.—OCTANDRIA.Plants whose Sowers contain eight stamens constitute this class;examples of which are to be seen in the Epilobium, Willow Herb.Class IX.—ENNEANDRIA.The ninth class is distinguished by its flowers bearing nine stamens.These cannot be easily mistaken. The Flowering Rush (Butomus) isthe only instance afforded in the British Flora. The Rhubarb (K/jram)affords a good example of this Class.

Class X.—DECANDRIA.

The tenth class contains plants with ten stamens, which are mostlydistinguished by the regularly formed corolla. They are easily di-stinguished. The Pink (Dianthus) is one.

Class XI.—DODECANDRIA.

The eleventh class consists of plants having flowers with from twelveto nineteen stamens: for example, Euphorbia, Spurge.
