We seldom see them at Mt. Takao. The stalk is pillar-shaped and upright, and is divided at the upper part into. They grow in the shade and the shape of the leaf looks like the one of Cryptotaenia japonica, which is why they are named.

There are some such clusters. 5 flower petals face inward, and a male stamen projects long outward from the inside while a female stamen is split into 2 at the top. The leaf is twice ternate compound leaf consisting of 3 leaves as one on the 3-split branched top. The leaf has a long stalk and the leaves grow alternative on the stalk. Lobules are elliptically-shaped about 2 to 10 cm long (Shoyo: each one that is leaf-shaped and leaf like one consisting of more than a few leaves) and has a rough sawtooth at the edge (sawtooth: Kyoshi, serrated edges like a saw-serrated edges at the tip of a leaf).
