Gigantochloa pseudoarundinacea, commonly known as west java pipe, is a large tropical clumping bamboo species native to Southeast Asia, particularly Indonesia and Malaysia. This bamboo is known for its tall, robust culms, which can reach heights of 7 to 30 meters and diameters of up to 13 cm, making it one of the largest species within the Gigantochloa genus.
The culms are typically green to yellowish-green, with smooth surfaces and thick walls, offering excellent strength and durability. These qualities make G. pseudoarundinacea a valuable resource for traditional and modern construction, water pipes, furniture, household utensils, chopsticks, toothpicks, edible shoot and charcoal
 
This species thrives in tropical lowland climates with ample rainfall and well-drained soils. Its fast growth and dense clumping nature make it suitable for soil stabilization, erosion control, and use in agroforestry systems. Due to its economic and ecological value, Gigantochloa pseudoarundinacea is widely cultivated across Southeast Asia as a multi-purpose bamboo.
