Abstract: In this revision, three species are recognised. A discussion is made on merging the genus Polysolenia into Leptomischus. Indopolysolenia burmanica Deb et Rout is reduced to a synonum of Leptomischus primuloides Drake.  A key to species is given below: l. Flowers larger, with corollas more than 2cm long.   2.Stipules 3-fid or torn;  Leaves narrowly lanceolate;  stigmas with 2 short obtuse   lobes  ......................................................  1.L. wallichii   2.Stipules entire;  leaves obovate to elliptic;  stigmas with 2 slender elongate lobes   .........................................................  2. L. primuloides 1.Flowers smaller, with corollas 6-6.5mm long;  stigmas with 2 lanceolate lobes ..........................................................  3. L. parviflorus
