ELEMENTS OF STRUCTURAL BOTANY. 



'Fig. 52). They are inserted on a disk which crowns the 

 ovary, as are also the five stamens, which are hence said 

 to be epigynous. In the centre of the flower are two short 

 styles projecting above the disk, and a vertical section 

 through the ovary (Fig. 53) shows it to be two-celled, with 

 a single seed suspended from the top of each cell. 



WATER-PARSNIP. 



59. The Water-Parsnip is a type of the large Order 

 Umbelliferce, which is well marked by the following 

 characters : 



1. The flowers are clustered in umbels, and these are 



generally compound. 



2. The calyx is perfectly adherent to the ovary, so that 



almost none of it projects above. 



3. The petals and stamens (Jive each) are epigynous. 



4. The ovary is two-celled, and is surmounted by two 



styles. At maturity the pistil separates into two 

 dry carpels.
