Flowers

56-Perigynous insertion

[FMP-field: image]

In the genus Rosa, flowers have a deep hypanthium, with many carpels, free (not fused with the hypanthium) and distinct (apocarpous gynoecium). Each of these carpels has a superior ovary, enclosed in the hypanthium. Here again, the insertion is perigynous. The styles protrude through the opening in the top of the hypanthium. NOTE: Look carefully! While it might appear that the ovaries are adnate to the hypanthim, they are actually FREE inside the sack-like hypanthium.
