3 rare bamboo species in Vietnam are in danger of extinction!
Among nearly 200 bamboo species in Vietnam, there are bamboo species that are extremely rare and are at risk of extinction. Here are 3 rare bamboo species listed in the Red Book of Vietnam.
Black bamboo (Phyllostachys nigra)
Black bamboo grows in mountainous areas above 1,300 m, near streams and places with high humidity. In Vietnam, black bamboo is abundant in Sapa (Lao Cai).
Black bamboo has a purple or black purple body, glossy. The underground stem is scattered, and the average diameter is 1.5 cm. Gas body hollow, straight cylinder, diameter 2-4 cm, height 6-7 m.
Oval-shaped black bamboo leaves are 8-12 cm long and 1-1.2 cm wide. Leaf tip pointed, tail oblong. Black bamboo leaves are often used as medicine.
Phyllostachys aurea (Phyllostachys aurea)
In Vietnam, Truc Hoa Long is only distributed in Bac Kan.
This species of bamboo is 5–12 m tall, and 2–5 cm in diameter. The distance between the nodes is 15–30 cm.
Bamboo transformed into a dragon is characterized by the fact that the segments near the base shorten and swell, crisscrossing each other, and looking like a flying dragon.
The dragon-shaped bamboo in Vietnam has a very narrow distribution, mainly in a few areas in the northern mountainous region, is in danger of extinction, and is in dire need of preserving its genetic resources.
Square bamboo (Chimonobambusa quadrangularis)
This species has a small, square, or nearly square body. The lower nodes often have roots that turn into short spines.
Square bamboo has scattered bamboo stems, 3 – 8 m high, 1 – 5 cm wide, thick walls, rough bark. The nodes at the base have prickly pneumatophores.
Bamboo leaves are square and oblong, 8 – 20 cm long, 1 – 2 cm wide, pointed tip. The body is thin, the sheath is triangular. The outside of the body is covered with many hairs, especially at the head and edges.
Like dragon-shaped bamboo, square bamboo is only distributed in Bac Kan
