Difference in shape

The first is the difference between their stems. The stem of the first plant is thick, usually in the shape of a rod or spindle, grows about 25 to 40 cm, and shrinks into a thinner cylindrical shape at the bottom. The stem of the second plant is either upright or oblique. It is generally cylindrical and does not branch. Its length is 12 to 46 cm. This difference is not easy to observe

The second difference is about their petals. The petals of the former are nearly round, about 1.5 to 2 cm long and about 1.1 to 1.5 cm wide. The petals of the latter are smaller, about 1.4cm long and about 1.2cm wide, with a slight difference. There is also the lip flap. The first one is golden yellow, showing a round diamond, while the second one is semicircular triangular

Another is the obvious color difference. The sepals and petals of the first kind are light yellow, while the sepals and petals of the second kind are white. We can observe this from the picture. However, there is another color difference that is difficult to see. It is the stamen column. The first color is orange, while the second is light yellow, but their length is the same

Difference in distribution altitude

The two plants are distributed in the same countries, but there are no small differences in altitude. The first kind is usually distributed in the forest with an altitude of 420 meters to 1 kilometer, while the second kind of plant has a higher altitude, about 1100 to 1800 meters. In other words, if you go climbing, you may encounter the first plant first, and then climb up, and then you may encounter the second plant. Is it interesting
