morphological character

Pitaya is a perennial climbing succulent plant. Rootless lateral roots of plants are widely distributed in shallow soil layers, with many aerial roots and can climb and grow. The root is dark green, stout, 7 meters long, 3 sides are flat and wavy, and the thickness is 10- 12 cm. Climbing roots grow on stem nodes, which can climb on other plants. Most ribs are 3, and there are small thorns in the depression of each stem node.

Because of its long-term growth in tropical desert areas, its leaves have degenerated, and its photosynthetic function is borne by its stems. Inside the stem is a large number of parenchyma cells filled with viscous liquid, which is beneficial to absorb as much water as possible in rainy season.
