SUB-CLASS I. MONOCHLAMYDE^. 



The flowers have a simple, usually sepaloid, perianth, or it may 

 be absent ; they are commonly monosporangiate. 



It must not be assumed that all Dicotyledons with apetalous flowers belong 

 to this sub-class : on the contrary, many such plants must, in view of the 

 aggregate of their characters, be placed in the other sub-classes. The plants 

 included here are such as have flowers the perianth of which appears to be 

 primitively simple, and not such as have flowers the perianth of which seems 

 to Lave become simple by suppression (see p. 506).
