Caption: Papillae on the lower surface of a rose flower petal (Rosa sp.). Papillae are projections from epidermal cells and in the rose they are conical in shape. The lower petal surface has smaller sized papillae than the upper surface. The lower surface of the rose petal contains some stomates for gas exchange (not seen in this image). Rose flower petals are soft to the touch due to the numerous and tightly packed papillae. The rose flower is the most common and widely cultivated garden flower in the world. It is appreciated for its fragrance and beauty since ancient times. Rose oil (attar of rose) is the steam-extracted essential oil from rose flowers that has been used in perfumes for centuries. Rose water, made from the rose oil, is widely used in Asian and Middle Eastern cuisine. Rose hips are occasionally made into jam / jelly, brewed for tea or used for their high Vitamin C content.
