What Kind of Flowers Are These?

 Last week, while visiting my sister in California, she received a beautiful flower arrangement from one of the daughters of her late friend.

 

They are very pretty and sit in a vase on her dining room table.

She is very grateful for the floral gift.  

 

The only problem is neither of us know what kind of flowers they are.

CAN ANY FLOWER-LOVER OUT THERE TELL WHAT KIND OF FLOWERS THESE ARE?
