I found confusion between the two on our site. So decided to go through the descriptions from Flora of Pakistan <http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=124629>, to find out the difference between the two: *Persicaria longiseta <http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=242100101>* (De Bruyn) Kitagawa <http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=242100101>: Ascending-erect, 15-60 cm high, glabrous, branched from base or above, annual herb. Stem brownish or reddish brown, glabrous, canaliculate. Leaves 2.5-12 x 0.75-3.5 cm, lanceolate-elliptic, acuminate, hairy, entire, with a rounded or cordate base, petiole 2-7 mm long. Ochrea 8-20 mm long, ovate, tubular, setose or ciliate, cilia almost equalling the ochreae or longer. *Inflorescence very laxly flowered, interrupted 0.8-4.0 cm long, terminal-axillary raceme. *Flowers up to 2.0 mm across, pedicel 1.0 mm long. Ochreolae 1.0-3.0 mm long, setose or ciliate, cilia 1.0-4.0 mm long. Tepals 5, biseriate, unequal, red, pink or whitish, ovate-obovate, obtuse. Stamens 5-8, filaments long. Ovary trigonous, rounded, with 3 styles, styles free above, fused below. Nuts trigonous, shining, black. Fl. Per.: May-August. GBIF specimens <https://www.gbif.org/occurrence/gallery?taxon_key=4034537>- one <https://www.gbif.org/occurrence/3307449840>, two <https://www.gbif.org/occurrence/3301793131>, three <https://www.gbif.org/occurrence/3456012293>
*Persicaria pubescens <http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=242100106>* (Blume) Hara <http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=242100106>: Very similar to Persicaria hydropiper (L.) Spach <http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=242100096> but usually much taller and with longer and larger leaves, up to 15 cm long, ochreae strigose, 10-15 mm long with much longer 8-10 mm long cilia. *Spikes up to 15 cm long, filiform, which are rather drooping, extremely slender and much interrupted. *Ochreolae glabrous-glandular with ciliate mouth. Perianth ± gland-dotted. Stamens always 8. Nuts trigonous. Fl. Per.: June-August. GBIF specimens <https://www.gbif.org/occurrence/gallery?taxon_key=4033392>- one <https://www.gbif.org/occurrence/2234732796>, two <https://www.gbif.org/occurrence/3399080555>, three <https://www.gbif.org/occurrence/3456505608> I think we can differentiate clearly based on the* size and slender and drooping nature of the inflorescence*. -- With regards, J.M.Garg -- You received this message because you are subscribed to the Google Groups "efloraofindia" group.
