A bowl of water by the river.

Leaves like lotus leaves, single stem, round leaves, shaped like a small bowl, with serrated edges and small white flowers; Dew and rain are often hung on the leaves, which can quench thirst and collect medicine. This medicine was originally dug in the forest on the high hillside by the river, so it was named. Because its rhizome is yellowish brown and each node has a pit, it is also called "Golden Whip Seven" and "Vol Seven".

A stroke by Wang Wen

Because its inflorescence is shaped like a thick brush, it is said that Zhou Wenwang used it as a pen to write poems, draw pictures and read official documents after passing through Shennongjia, hence the name. Because this plant is a parasitic plant, it often grows in the roots of other plants, so it is also called "borrowing children from mothers".

Seven leaves and a flower.

Seven leaves and one flower, also called schefflera, is a different plant. Its biggest feature is that a flower emerges from a circle of whorled leaves, which is not unusual. Unusually, the shape of this flower is very similar to its leaves. It can be divided into two parts, outer flower and inner flower. The flowers outside are very similar to leaves, there are about six, and there are about eight flowers inside, which can be seen at a glance.

As for the whorled leaves with seven leaves and one flower, must they be composed of seven leaves? The answer is no, and six leaves are also common.
