The last one is Spiranthes sinensis var. amoena, which is commonly known as the Chinese Spiranthes. It is said that it is a species of orchid occurring in much of eastern Asia, west to the Himalayas, south and east to New Zealand, and north to Siberia.
The flowers are arranged in a helix around the spike 20cm high, and flower sequentially. This is why it is called "neji-bana" (meaning screw flower ネジバナ) in Japan.
