What is the name of this herb vine?

This is Sedum emarginatum Migo (Latin name: Sedum emarginatum Migo), alias: slate, September cold, immortal, slate returning to the sun, sparrow returning to the sun, rock plate, Sedum of Sedum. The lower part of the stem node lies flat on the ground or underground, and adventitious roots are born on the node; The upper part is upright, lavender and slightly quadrangular; The top of the blade is round and concave; The branches and leaves are as dense as carpets, and the flowers are small and yellow, which are planted on the branches. The flowering period is May-June, and the fruiting period is June. Some leaves are purplish red when overwintering outdoors. Drought-tolerant, like semi-cloudy environment. Yunnan, Sichuan, Hubei, Hunan, Jiangxi, Anhui, Zhejiang, Jiangsu, Gansu, Shaanxi, Fujian and other places. Born at an altitude of 600- 1800 meters on a shady hillside. The whole plant can clear away heat and toxic materials, dissipate blood stasis and reduce swelling, and treat traumatic injury, heat furuncle, sore poison and other diseases.

morphological character

Perennial herbs. Slender stem height 10- 15 cm. The leaves are opposite, spoon-shaped obovate to broadly ovoid, with a length of 1-2 cm and a width of 5- 10 mm, with a rounded top, slightly notched base and short spacing.

Inflorescence cymose, terminal, 3-6 mm wide, with many flowers and usually 3 branches; Flowers sessile; Sepals 5, lanceolate to oblong, 2-5 mm long and 0.7-2 mm wide, with obtuse apex; Short base distance; 5 petals, yellow, linear-lanceolate to lanceolate, 6-8mm long and1.5-2mm wide; 5 scales, oblong, 0.6 mm long, obtuse, 5 carpels, oblong, 4-5 mm long, and connate at the base. Clam is slightly forked, and its ventral surface has shallow cystic uplift; The seeds are small and brown. The flowering period is May-June, and the fruiting period is June.

Leaf morphology

The stomata of Sedum lineatum leaves are scattered individually or gathered in groups, and the epidermal cells are rectangular or irregular, and the cells are closely combined without gaps. The stomata are ovoid and ovoid, with outer arch cover 1-2 layers, smooth, wrinkled or wavy horny membrane, and waxed paper grains.

Stem morphology

The stem consists of epidermis, cortex and vascular column. The phloem is located outside the xylem, and there are many different cells in the tissue. The cells in its stem all contain brownish-yellow substances.

Root morphology

It consists of cork layer, cortex and vascular bundle from outside to inside, and has no pulp. Root cells contain a lot of starch granules and brownish-yellow substances.

Pollen morphology

The three-dimensional shape is nearly spherical or rectangular. The cell morphology and contents of pollen will change regularly at each development stage. The original nectar in phloem is stored in nectar-producing tissues in the form of starch granules, hydrolyzed into nectar during nectar secretion, and oozed from stomata and epidermal cells.

component content

The content of quercetin in Sedum alfredii by HPLC was 3.6- 18μg/ml, the average recovery was 100.65%, and the RSD was 2.02%. The isorhamnetin was 1.06-5.30μg/ml, the average recovery was 10 1.99%, and the RSD was 4.95%. The content of flavonoids in its leaves is extremely high, and the extraction rate of 20% times is 14. 1%. Because it contains alkaloids, sitosterol, flavonoids, Sedum alfredii heptylose, fructose, sucrose and organic acids, Sedum alfredii has a good effect on improving coronary circulation. The content of K is 298.94μg/ml, which is helpful to prevent and treat hypertension. Sedum dentatum is a kind of zinc hyperaccumulator, which makes it have strong tolerance, absorption and accumulation ability to high content of zinc in soil, and provides a new germplasm resource for solving zinc pollution in soil.

Growth characteristics

It is a perennial creeping succulent herb. Cold-tolerant, like semi-shady environment, flowering in April-May, bearing fruit in June-July. Some leaves are purplish red when overwintering outdoors.

Habitat distribution

Born at an altitude of 600- 1800 meters on a shady hillside. Location: Yunnan, Sichuan, Hubei, Hunan, Jiangxi, Anhui, Zhejiang, Jiangsu, Gansu, Shaanxi, Fujian and other places.
