<div type="discussion"><p>C. poensis is a little known species occurring in low mossy forest on the summit of G Pueh. In 19811 searched for it but without success; it seems likely that the two collections were made on the summit of a higher peak elsewhere in the G Pueh Range. From herbarium material it seems to be close to C. marginatus but is immediately distinguished by the grouped leaflets.</p></div>
