Callitriche deflexa A. Braun ex Hegelm. was once recorded as an uncertain species in the first edition of the Flora of Taiwan, but was subsequently eliminated from the flora of Taiwan. Recently, it was found in northern Taiwan and can be easily distinguished from other members of the genus Callitriche in Taiwan by its schizocarp with a pedicel up to 4 mm long and usually being longer than the leaves. This paper provides a morphological description, distribution, photographs, and line-drawing to aid its field identification.
