Status in China Critically Endangered (CR)

Description:

Shrubby running bamboos; culms erect, 1.5-2 m tall, 5-6 mm in diameter; internodes terete, 15-20 cm long, smooth and glabrous. Branches usually solitary at each node. Culm leaves persistent; sheaths tightly culm-clasping, minute hairy abaxially when young, glabrescent, subtruncate at apex, margin densely ciliate; auricles lacking; ligules 1-1.5 mm high; blades erect, lanceolate, hispidulous on both surfaces when young. Foliage leaves: sheaths puberulous when young; auricles lacking; ligules 1-1.5 mm high; blades ovate-lanceolate to oblong-lanceolate, 12-30 cm long, 2.5-5.5 cm wide, shortly pubescent toward base beneath, reticulate veinlets conspicuous.

Distribution:

The species is endemic to Hong Kong and only one small population exists in Fo Tan.

Habitat and Ecology:

In forests.

Discovered in 1938 from Sha Tin Tsuen in ravines on moist clay, this species is endemic to Hong Kong; but up till now, no flowering specimen is available, therefore its systematic position is still unclear and is thus of special botanical interest. The locality of its occurrence is very close to a village, so it is susceptible to human activities. AFCD had conducted ex-situ conservation and has been trying to propagate it artificially.
