Ancient book names: Wahua, Xiangtiancao, Tianwangtieta grass, belonging to the genus Lithocarpus of Crassulaceae, are perennial Carex plants, which are widely distributed in the sunny slopes of deep mountains and also grow in the gaps between rocks and ancient roofs, and are drought-resistant and cold-resistant. In early spring, the snow melts, and bulbs are like cones of pine trees in the mountains. As the temperature gets warmer, the scales crack like tiles, showing a lotus shape. The stem in the middle of the sphere is 30-40 cm high, and long spikes are arranged around the stem, which looks like a pine tree from a distance, hence the name. Bulb leaves are fleshy, thick pulp, oblong scales, sharp apex, smooth surface, purplish leaves without obvious taproots and well-developed fibrous roots. The petals are divided into five pieces, white, reddish or white, with ten stamens and five pistils. The flowering period is more than two months.
Before and after Duanyang Festival, bulbs grew to the size of thumb, so it was interesting to pick them one by one and plant them in small pots on the balcony. In particular, it is very chic to tie it up with thread and hang it naked indoors, grow into a U-shape and decorate the room. Scale epidermis contains wax, which can prevent water evaporation. In the season of drought and water shortage, the water stored in fish scales is used for the normal growth of stems and leaves until the water supply is completed and the ball withers to complete its growth cycle. Scaly stems and leaves of Pinus elliottii can be used medicinally. Take it in August and September and dry it. Indications: dry mouth pain, bloody dysentery, hemostasis, Shui Gu, etc.
