Abstract: The Sino ̄Vietnamese limestone karsts show specially high levels of plant diversity among Indo ̄China florasꎬ
and also are biodiversity hotspots in the worldꎬ and many new species or genera of Gesneriaceae have been found there
recently. The genus Litostigma Y. G. Weiꎬ F. Wen & M. Möller (Gesneriaceae) was reported firstly from limestone areas
of southwestern China in 2010ꎬ included two speciesꎬ namely Litostigma coriaceifolium Y. G. Weiꎬ F. Wen & M. Möller
(Typus generis) from southwestern Guizhouꎬ and Litostigma crystallinum Y. M. Shui & W. H. Chen from southeastern
Yunnan. We fortunately found Litostigma crystallinum from Ha Giangꎬ northern Vietnamꎬ and reported here to sufficient ̄
ly know the diversity of Gesneriaceae in Vietnam. The description of Litostigma crystallinum was supplemented base on
the collections from Ha Giangꎬ northern Vietnamꎬ and the habitat photos were also provided. The discovery of Litostigma
crystallinum from northern Vietnam demonstrates the closely floristic relationship between northern Vietnam and southern
China once again. The new localities are also very important for the conservation of Litostigma crystallinum.
