Treasures of Mt. Takao

Mt Takao is located at the borderline of warm-temperature zone and cool-temperature zone and various plants from both zones grow. There are a lot of naturally grown plants and their visitors can enjoy seasonal flowers. Over 1,500 kinds of plants are confirmed which is relevant to the number of kinds naturally grow in England. Also, over 60 kinds of plants are first found in Mt. Takao such as Takao Sumire (V. yezoensis f. discolor) and Takao Higodai (Saussurea sinuatoides).

Cephalanthera erecta
Cephalanthera erecta Orchidaceae
They are perennial plant that grows in the sunny copse of mountain districts and hills (perennial plant takes several years to grow). They are rare species we seldom see at Mt. Takao. While Cephalanthera falcate bears yellow flowers, their flowers are white. This is why they are named Cephalanthera erecta. The flower is about 1.5 to 2 cm in diameter. 5 to 10 flowers bloom on the top of stalk and most of the flower petals are half-open. They have 3 flower petals and 3 calyxes and there is yellow ‘costa’ (Ryukisenn) inside of the centered flower petal. The leaf looks like bamboo grass, is about 3 to 8 cm long and 1 to 2.5 cm wide, 5 to 6 leaves grow alternate as if they are wrapping the stalk. In the case of very similar Cephalanthera longibracteata, bract leaf (Houyou: transformed leaf at the root of flower stalk) just below the flower grow higher than flowers. On the contrary, in the case of Cephalanthera erecta, the bract leaf is short. This is a good point to distinguish one from another.
