and cosmetics, medicinal uses (phytotherapy) and gastronomic.
• There is a huge variety of cultivars (over 30 000) from various hybridizations, and each year new

tall, sometimes reaching 20 m climbing over other plants. They have semi-ligneous stems, usually
erect (sometimes crawling), some rough and flaky texture, with notable epidermal formations of
various shapes, persistent and well developed (stingers).
• The leaves may be evergreen or deciduous, stalked and imparipinnadas with between 5-9 serrated
leaflets and basal stipules. Often the presence of attached glands on margins, fragrant or not.
• The flowers, which emerge in racemose inflorescences, forming curds are generally aromatic,
complete and hermaphrodites; regular, radially symmetrical (actinomorphic). The perianth is well
developed. The prominent floral hypanthium or receptacle urn-shaped (concave thalamus and
deep). The calyx is dialisépalo, 5 part green. The sepals may be simple, or sometimes in complex
with stylized side lobulations. Dialipétala Corolla, symmetrical, consisting of five regular petals (or
multiples of 5), sometimes notched, and various bright colors, also white. The corolla is usually
"double" or "full" by transformation of stamens into petals, mostly in the cultivars. Androceo
comprises spirally arranged numerous stamens (several whorl), usually in a multiple number of
petals (5x). Apocárpico gynoecium (composed of several separate pistils). Nectarios present, which
attracts pollinating insects to favor predominantly entomophilous. Perigina (ovary middle),
numerous carpels uniovulados (one ovule per carpel) and each carpel produces an achene.
• The fruit of the flower is known as cinorrodon infrutescencia or hip, a "fruit" composed of multiple
small nuts (poliaquenio) separated and enclosed in a fleshy receptacle (hypanthium) and bright
color when ripe.

richest plant sources of this vitamin. It also contains vitamins A,
