A new subspecies and two new combinations are proposed in Onagraceae. Ludwigia glandulosa Walter subsp. brachycarpa C.-I Peng, subsp. nov. is morphologically distinct from the typical subspecies, with smaller capsules and leaves, different seed coat, and a restricted distribution. Epilobium sect. Pachydium (Fischer & C. A. Meyer) Hoch & K. Gandhi, comb. nov. refers to a distinctive group of species formerly known as Boisduvalia Spach and as Epilobium sect. Boisduvalia (Spach) Hoch & P. H. Raven. And Chamaenerion speciosum (Decaisne) Hoch & K. Gandhi, comb. nov. is proposed for a distinctive Himalayan species originally described in Epilobium.
