Cladium brevipaniculatum (KÜK.) KÜK. is said to differ from 'C. tenax' (wrongly accepted by KÜKENTHAL as the correct name for C. gunnii) by the more robust, 1-leaved stems, the shorter and narrower panicle, and the appressed uppermost glume. In the New Guinea collections I have seen the stems are very variable in width and 1-2-leaved; the uppermost glume is at first erect, finally spreading.
