Character identification
The stems are square-cylindrical, ranging in length from 1 to 4 mm in diameter, with a purple or yellow-purple surface, longitudinal grooves, and pilosity. They are hard, fibro-carious, yellow-white, and white in the medullary canal. The leaves are often detached or broken, and the entire person is flattened into an oval or oval lanceola.
Basil
Shape, length 2.5 ~ 5cm, width 1 ~ 2.5cm, apex obtuse or pointed, base gradually narrow, irregular teeth or near the edge of the edge, both sides near hairless, below the gland points; petiole length of about 1.5cm, was micro Fluffy. Pseudoglobose inflorescences slightly hairy, corolla shed; bracts oblanceolate, calyx campanulate, yellow-brown, membranous, reticulate, externally pilose, inside surface throat pubescent. The placebo contains small nuts. After smashing, there is a strong aroma, spicy and cool feeling.
Thin stems and rootless plants are preferred.
Microscopic identification
Stem cross-section: square or lower cross-section is round. Epidermal cells 1 column, external stratum corneum, and see the epidermis or base residues. Corners under the epidermis with thick angular tissue. The vascular bundles are arranged in a ring. The bast phloem has bast fiber bundles on the outer side, intermittent loops, and fibrin cell wall wood. Formation layer continuously loops. The xylem was thick and thick at the corners; the cells of the secondary xylem were woody. Myelin width Lei.
Leaf epidermis: wavy curved wall of upper epidermal cells. The lower epidermis cells are similar to the epidermis, and there are stomata in the upper and lower epidermis, most of which are straight-axis. Non-glandular hair straight or curved, length 38 ~ 1560μm, tip apex, wall with a defect. There are two types of glandular hairs, one single cell in the stem, and 2 (or 1) cells in the head; the other is squamous glandular hairs, single cells in the pedicel, and often 4 cells in the head.
Very high sample collection and release volumes.Greatly improved the accuracy of the inspection . Patented polymer synthetics handle 4.The hidden danger of nasopharyngeal swab rupture is completely solved.iCleano swab is ideal for collecting large amount of samples and rapid elution of thespecimens. It instantly release the specimen into the transport medium, which is welladopted in the field of molecular genetics, forensics, clinical laboratories sectors etc.
