Growing environment is different, distribution range is different, leaves are different, plant height is different.

The light bamboo leaves like moist environment, shade tolerance, is irradiated by strong light is easy to grow poorly, mainly grows in the mountain slopes, woodland and roadside shade, bamboo leaves mainly grow in sunny, precipitation-rich tropical and subtropical areas, a few grow in the frigid and temperate zones.

The light bamboo leaf is a graminaceous perennial evergreen bamboo-like tree plant, mainly distributed in Jiangsu, Anhui, Zhejiang, Jiangxi, Fujian, Guangdong, Sichuan, Yunnan and other regions, the bamboo leaf is a graminaceous perennial herbaceous plant in Shandong, Henan and south of the Yangtze River Basin are distributed.

The stems and leaves of the light bamboo leaves are mixed together, the leaf blade is long lanceolate, the leaf blade has longitudinal veins growing longitudinally and horizontally, forming a rectangular network, the leaf blade of the bamboo leaves is narrowly lanceolate, the surface of the leaf blade is smooth, the back side of the leaf blade is rough, and the veins of the leaf blade are very prominent.

The plant of the light bamboo leaf is about 40-80 centimeters, the rootstock is slender and erect, and the root shows a fusiform shape, the plant of the bamboo leaf is about 40-100 centimeters in height, and grows a little taller than that of the light bamboo leaf, the rootstock is shortened inward, and the middle of the stem is hollow.
