Roses, also known as thorns, thorns and smiles. It belongs to Rosaceae, deciduous shrub. The plants are clustered and the stems are tendrils and spiny. Leaves alternate, odd pinnate compound leaves. Flowers have five colors: red, white, yellow, purple and black. Most of them are red, and Huang Qiangwei is the top grade, which is fragrant in late spring and early summer. Wild roses are single petals.
Wild roses are native to Asia and Europe and are widely distributed. It is cultivated all over China, often with hedges as the frame and bamboo as the screen. In Rosaceae, it is juxtaposed with rose and Chinese rose. Rosa davurica has high economic value, from which aromatic oil and essence can be extracted. The seeds and roots of wild roses can also be used as medicine.
Rose, rose and rose are all sister flowers of Rosaceae, so their shapes are very similar and easy to be confused. Here, we compare their characteristics. It is much easier to distinguish the "three sisters" in this way.
Both roses and roses have upright branches (of course, a few roses are creeping), and the stems of roses are very low, while roses are light, dry and strong. Rose plants are tall, but the stems are light and long, and the branches crawl or climb.
The stems of Chinese rose and Chinese rose are larger and generally have hooks, saving 3 or 4 thorns every time; The new branches of Chinese rose are purplish red; The stems of roses are covered with dense villi and needle-like spines, and the stems are black. The leaflets of Chinese rose flowers are generally 3-5, and the leaves are flat and smooth; Roses have 5-9 leaflets, with toothed leaves and flat but pilose leaves; There are also 5-9 rose leaflets, but the lower leaves are wrinkled, the back of the leaves is white with small thorns, the whole leaves are thick and the veins are sunken.
Generally speaking, Chinese rose is a single flower, but there are also several clustered flowers, generally 1-3, with a flower diameter of about 5 cm or more and a long flower stalk, which is unbeaten in the rose season, so it is called "Moon Red", "Rose" and "Catharanthus roseus". Rosa multiflora usually has 6-7 flowers, which are cone-shaped corymbose inflorescences, born at the top of branches, with a flower diameter of about 3 cm, and only bloom once a year. Roses are solitary or clustered 1-3 flowers with short stalks, similar to wild roses, and only bloom once in summer, but the fragrance of roses is much stronger than that of roses and roses.
In addition, the sepals of rose and rose do not fall off after flowering, but the sepals of rose will fall off; Rose and its fruit are spherical, and rose is oblate.
Rose and rose are sister flowers of different species belonging to the same family. Their similarities are: both belong to Rosaceae; Deciduous or semi-deciduous shrub with erect or climbing stems, usually spiny; Leaves alternate, odd pinnately compound, with stipules; Flowers solitary or corymbose; Sepals and single petals are five each, and double petals are the majority; There are many stamens, and most pistils are enclosed in pot-shaped receptacle, which is fleshy after maturity and contains most or a few achenes. The similarity in appearance and form often confuses the two. Many people confuse roses with fragrant China roses. In fact, there are great differences between different species.
Rose and rose are both roses in English, and they are both Rosaceae plants, and their genetic relationship is relatively close. The main differences between rose and rose are as follows:
(1) Rose leaves are few, with 3-5 leaves and 5-9 leaves.
(2) There are fewer thorns in the rose, but more thorns in the rose.
(3) The leaves of roses are full of light, but the leaves of roses are dim.
(4) Chinese rose flowers are large and colorful; Roses are smaller and usually pink. The second kind of rose is slightly larger, but flat and disc-shaped, which is easy to distinguish from roses.
