Vascular bundles outside the tough type, phloem is narrow, 5 to 8 columns of cells, thin-walled, containing starch grains, sometimes visible small calcium oxalate crystal; formation layer is not obvious, wood ray width 5 to 8 columns of cells, scattered fibers Bundles; There are many fibers around the catheter, and there are a few irregular cells.

(9) Calcium oxalate has less square crystals, which are oblate, oblong, or thin-columnar, with a diameter of 8 to 30 μm and a length of up to 50 μm.
(10) The starch granules are sparse, single-grained spherical, with a diameter of 3 to 10 μm, and the stratification is not obvious.
2. Loranthaceae
Stem (4mm in diameter) cross section: more than 10 rows of cells in the cork layer and brown cells in the outer cork cells. Epidermal cells sometimes remain. The cortex is narrow, about 4 to 7 rows of cells containing brown matter and starch granules. The number of stone cells is numerous, and it forms a ring zone with the buckwheat fiber bundles. The phloem is narrow and there are stony cells or stone cell clusters in the ray. The formation of layers within the beam is obvious. Narrow wooden rays, 1 to 5 rows of cells. The catheters are in a single row or 2 to 3 clusters surrounded by a large number of wood fibers and wood parenchyma cells. There is a group of stone cells in the pith, and parenchyma cells contain starch grains and brown substances. The stone cell contains calcium oxalate cubes or brown substances.

Leaf cross-section: the upper and lower epidermis are all stomata, cells are small, rectangular. The upper surface of the epidermis has one epithelium under the skin; the upper part of the palisade tissue is composed of 3 to 4 rows of cells with longer cells; the lower one is composed of 2 to 3 rows of cells with short cells arranged neatly and tightly; the middle is sponge tissue with loose arrangement inside. Contains small round calcium oxalate clusters, and small oxalic acid crystals scattered, occasionally stone fine
