Petiole ring is the difference between them, which is obvious. In fact, Chunlan has this kind of thing, while Huilan has nothing
The number of leaves is also very different, the former leaves are very rough, very wide and long. The latter is more smooth, narrower and shorter than the former. The number of spring orchid leaves is only about four or five, while the number of Whelan leaves is more, at least seven, and up to fifteen.
Huilan's veins are actually very distinctive. If we look at the flowers facing the light, we can develop them to have very dense veins, which are still transparent. The number is about seven to nine. The back of Whelan's leaf has a raised edge, and if it is facing the light, it will have a translucent edge.
The flowers of Chunlan are relatively few. Generally, there is only one flower on a sword. When there are more flowers, there will be two. The number of Whelan is much more. Generally, there are many flowers in a sword, probably between six and twelve. Generally speaking, this is the orchid with the largest amount of flowers. Of course, it's still the orchid in China, not all the flowers, and its flower pole is relatively thick.
Flowering time, the former is generally in February and March, the latter is from March to May. All in all, there are still many differences between them, so if you want to identify it carefully, it is OK
