[ ] the original morphology
1freyn cinquefoil herb perennial is herbaceous, tall 8-25cm. There are runners or not obvious. Root branching, clusters. Stems slender, erect or ascending, puberulous. Basal leaves palmate leaves with petiole is long three,4-30cm; stipules membranous, brown, sparsely villous outside; leaflets oblong, ovate or elliptic, apex acute or obtuse, base cuneate or broadly cuneate, margin serrate most acute, both surfaces sparsely pilose along veins below tiled, dense; cauline leaves 1-2, leaflets and basal leaves are similar, only the petiole is short, lobes serrated edge reduction; stipules herbaceous, a notch shape incised, sparsely villous. Flowers bisexual; corymbose cymes terminal; flower diameter of 0.8-1cm; sepals 5, triangular ovate, apex acuminate, epicalyx segments 5, lanceolate, apex acuminate, and sepals subequal, tiled pilose outside; petals 5, oblong to obovate, apex emarginate or rounded, pale yellow; style subterminal, the upper base of the coarse, fine. Mature achenes ovoid,0.5-1mm diameter, surface have significant veins. Flower, month of fruit period 3-6.
2of the trefoil trefoil cinquefoil Potentilla and main differences: the variants of stems and petioles densely pilose. Both sides were carried out leaflets pilose or micro development pilose, especially along veins dense, leaflets rhombic ovate or broadly ovate, margin with obtuse serrate, stalk or runners on the stipules ovate, entire, extremely dilute apex2 crack, flowers, month of fruit period 4-5.

[ character ]
Character identification of trefoil anserina roots spindle-shaped, cylindrical or dumbbell shaped, slightly curved, some resembles a bee abdominal, length 1.5-4cm, diameter 0.5-1.2cm, surface grey brown or yellow brown, rough, wrinkled and raised root marks and fibrous root, the petiole residues, pilose. Qualitative hard, not easy to break, section granular, brown or dark brown, the color depth, in the expansion of microscopically small white crystalline. Gas micro, bitter and astringent, micro with cool feeling.
Microscopic identification of rhizome transverse: cork for the more than 10columns of cells, pale yellow. Cortical stenosis,4-10columns of cells. Phloem sieve group easy to see. Cambium ring. Xylem several or more than 10groups. Ray wide. The pith is developed. The parenchyma cells contain starch grains, some contain calcium oxalate crystals.
Root transection: cork for the rows of cells. Cortical stenosis: endothelial layer is special, has 2 floors, which has two spaced layers of parenchyma cells, Casparian dots evident. The pericycle of 1rows parenchyma cells. Phloem is wider, visible screen groups. Cambium was ring. Xylem is less, be radially arranged. The pith of small. The parenchyma cells contain starch grains and calcium oxalate crystal.
Characteristics of rhizome yellowish brown powder: powder. Many starch grains, single round, the diameter of 3-17μ m, umbilic point, crack shape or a bird shape, layer is not obvious; compound grain by2-4particle composition. A scalariform and reticulate vessel diameter is 7-30μ M. Calcium oxalate crystal diameter is20-30 μM. In addition, a cork cell and non wood parenchyma cells.
[ ] identification
Physicochemical identification, take the coarse powder1g, plus ethanol reflux for 15min,20ml, filtration, the filtrate for the following test: (1) to obtain filtrate1ml, plus sodium nitrate little, adding sulfuric acid solution of about 1ml, marked in red.
(2) the1ml filtrate, plus 1% ferric chloride ethanol liquid1-2 drops of solution, blue green.
(3) with4ml filtrate, the evaporating dish steaming, adding acetic anhydride1ml dissolved, along the evaporating dish wall add 1 drops of concentrated sulfuric acid, to purple-red, later changed to green.
