HYDRANGEA FAMILY. Hydrangeaceac. 



white or cream-colored flowers; the calyx top-shaped, with 

 four or five lobes; the petals four or five; the stamens 

 twenty to forty, inserted on a disk; the ovary inferior, with 

 three to five styles; the capsule top-shaped, containing 

 many oblong seeds. These plants were named in honor 

 of King Ptolemy Philadelphia. They are often called 

 Mock- Orange, because the flowers often resemble orange- 

 blossoms. The commonest name, Syringa, is confusing, 

 because that is the generic name of the Lilac.

to twelve feet high, with smooth, pale, woody stems, dark- 

 green leaves, sometimes slightly toothed, very smooth and 

 shiny, and pretty flowers, in clusters at the ends of the 

 branches. They are each about an inch across, with four 

 or five, cream-white petals, rolled in the bud, and a golder 

 center, composed of numerous, bright-yellow stamens.
