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
