Therefore, though 3-carpelled ones are most common, 4—5 

 carpelled individuals are also to be seen. Some of the flowers 

 reminded me, by their forms, why Thunberg should have de- 

 clared their close resemblance to Aconitum Lycoctonum. The 

 form and number of root-stocks, the dissection of leaves, the 

 number of flowers on raceme, the magnitude of flowers, the 

 height of hood, the shape of nectary, the number of carpels, 

 hairs on carpels, all these particulars seem to have no definite 

 rules of co-variation ; but the earlier flowers are larger and 

 have more frequently numerous pistils than the later ones.
