Abstract


Schizostachyum cambodianum is a new species of woody bamboo from the Cardamom Mountains in Cambodia. It is instantly recognized by a very large suborbicular projection at the base of the culm sheath. The only other bamboos which are known to consistently show such similar suborbicular projections are the Chinese species Schizostachyum hainanense, S. auriculatum, and S. dumetorum. In these species, however, the projections are less than one cm wide, whereas in S. cambodianum, it is particularly impressive, developing to about 3 cm wide. S. cambodianum can further be distinguished from its Chinese relatives by forming lax clumps due to its long-necked rhizomes and largely glabrous culm sheaths with only scattered pale hairs.
