On the whole the resemblance between the structure 

 of the Marsh-Marigold and that of the Hepatica and 

 Buttercup is sufficiently great to justify us in placing it in

26. Having now made yourselves familiar with the 

 different parts of these three plants, you are to write out 

 a tabular description of them according to the following 

 form ; and, in like manner, whenever you examine a new 

 plant, do not consider your work done until you have 

 written out such a description of it.

In the form the term cohesion relates to the union of 

 like parts ; for example, of sepals with sepals, or petals 

 with petals ; while the term adhesion relates to the union 

 of unlike parts ; for example, of stamens with corolla, or 

 ovary with calyx. Neither cohesion nor adhesion takes 

 place in any of the three flowers we have examined, and 

 accordingly, under these headings in our schedule we 

 write down the terms polysepalous, polypetalous, &c., to 

 indicate this fact.
