蔓 is a bound form that appears in compounds related to climbing vines and creeping plants, such as 藤蔓 (téng màn) and 蔓草 (màn cǎo). However, note that the pinyin given here is mán, which in standard Mandarin is the reading for 蔓菁 (mán jing, 'turnip'), not for the vine meaning. The gloss 'climbing vines' is correct for the màn reading, so this row has a tone mismatch. As a bound form, 蔓 never stands alone; it must be used inside a longer word.
