According to a label in SING the plant is (was?) cultivated by the Chinese in Singapore and exported to China, where it is used as a diuretic.


The habit is much like that of B. barbata, but the texture of the pericarp is quite different. The nut character is the most distinctive; sessile or stalked spikelets is also a good distinction, except in very small plants. The hairiness of the stem is variable.
