= Rose

A <rose> is a <flowering plant> of <Rosa>, within <Rosaceae>. The term also refers to its <flower>. <Roses> are typically shrubs or climbing plants, and many cultivated forms have a <hybrid (biology)> origin and are selected for floral traits. Their flowers have a characteristic cup-shaped <hypanthium>, with numerous \x[stamens]{magic} around the rim and many separate <carpels> inside.<Rosa in New South Wales Flora Online>[genus description and cultivated hybrids]{ref}

After successful reproduction, the <hypanthium> can enlarge into a <rose hip>. The small dry <fruits> enclosed within it are <achenes>; the fleshy outer structure is not one giant <seed> or a single enlarged <ovary (botany)>. Cutting a mature hip lengthwise and locating the individual <achenes> provides a direct anatomical comparison with a <strawberry>, whose <achenes> sit outside its fleshy <receptacle (botany)>.<Rosa in New South Wales Flora Online>[achenes enclosed within the swollen hypanthium]{ref}

This comparison explains a useful feature of <Rosaceae>: related plants can produce conspicuously different edible or seed-bearing structures by enlarging different tissues and arranging their <carpels> differently. The family relationship is consequently richer than resemblance between petals alone.
