  • Dictyosperma olgae Regel & Schmalh.
  • Nasturtium officinale var. olgae (Regel & Schmalh.) Busch
  • Nasturtium uniseriatum Howard & Manton
  • Pirea olgae Dur.
  • Rorippa microphyllum (Boenn. ex Reichb.) Hyl. ex Love & Love

    Differs from Nasturtium officinale R. Br. only by its narrow, linear fruit and seed characters as mentioned in the key. This has 2n=64 (while Nasturtium officinale has 2n=32), apparently an allotetraploid of Nasturtium officinale.

    Leaves and stem turn purplish in autumn. Siliquae 15-22 mm long, usually 1 mm broad., slender on up to 20 mm long pedicels, spreading; valves smooth glabrous; seeds uniseriate, c. 0.8 mm long, with c. 100 polygonal depressions on each face.

    Fl. Per.: April July.

    Syntypes: Germany: Gegend von Leipzig bei Abtnaundorf Reichenbach ; Rothenfelde, Boenninghausen..

    Distribution: Europe, C. and W. Asia, Africa and America.

    This species is confined to the N.W.F.P. area, while the previous one is present almost throughout Pakistan. Sterile hybrid between the 2 species may also be found. Hedge (l.c. 215) records it from Kohat: Lamond 1565 (E); Rech.f. 30228 (W).
