The ring of an orchid.
The rings of orchids, Chunlan and Jianlan have petiole rings, which are located within the range of 1-4cm from the orchid bulbs, showing annular protuberances, the dividing line between petioles and leaves, and leaves wilting and breaking from the ring. The appearance of petiole ring also indicates that the seedling is about to grow.
Orchid leaves often fall off in a certain part of the base, which is often composed of several layers of parenchyma cells separated between the leaf and the leaf base (petiole), called "joint" (petiole ring). In a variety of domestic epiphytic orchids, the joint of the leaf is particularly obvious. There are also "petiole rings" before the leaves fall off, and "petiole marks" after the leaves fall off; the orchid boundary is commonly known as "false rings".
