Flower/Fruit: Fl. Per.: May-July.
Type: Type: Zanskar, Ladak, W. Koelz 2926a (GH, isotype 2946b!)
Distribution: Distribution: Pakistan eastward to Ladak.
Comment/Acknowledgements: The gathering Bowes Lyon 789 from Chitral is tentatively placed here. It differs from Rochelia laxa in the shorter fruiting pedicels (2.5-3 mm long) and which is solitary or 2-3 branched from the base. In Rochelia laxa the fruiting pedioels are generally 3-8 mm long and stem branched from the base. The specimen also has a different indument.
