 in rings one above another, as mothenvort, catnip. 



2. Raceme. Having the florets on short pedicels, ar- 

 ranged along a general peduncle, as currants. 



3. Panicle. Having some of the pedicels, along the gen- 

 eral peduncle of the raceme, divided, as in oats.

 elongated general receptacle, as wheat, mullein, &c.

 place like the braces of an umbrella, bearing florets on 

 their -extremities, as carrot, dill, fennel, &c.

 ral flower-stems spring from one centre, but differs in 

 having those steins irregularly subdivided, as clder,&c.
