4a. Persicaria lapathifolia var. lapathifolia

Polygonum lapathifolium L., Sp. Pl. 360. 1753; Hook. f., Fl. Brit. Ind. 5: 35. 1886 p.p.; D.A.Webb & Chater in Tutin et al., Fl. Europ. 1: 79. 1964; Coode & Cullen in P.H.Davis, Fl. Turk. 2: 273. 1967; Rech.f. & Schiman-Czeika in Rech.f., Fl. Iran. 56: 57. 1968 p.p.; R. R. Stewart, Ann. Cat. Vasc. Pl. W. Pak. & Kashm. 207. 1972; Bhopal & Chaudhri in Pak. Syst. 1(2): 76. 1977 (p.p.); Polygonum tomentosum Schrank, Baier. Fl. 1: 669. 1789; Polygonum hassanabdalicum Chaudhri in Pak. Syst. 3(1): 28. 1987 syn. nov.

Fl. Per.: June-September.

Type: Described from France, Hb. Linn. 510/6 (LINN).

Distribution: Europe, N.W.Africa, S.W.Asia.

Though the ochreae are eciliate but few finely ciliate forms are also met which offer difficulties in identification. Finely ciliate forms resemble Persicaria maculosa. However, P. maculosa can readily be distinguished by its bright red flowers, eglandular leaves and peduncle.

The type specimen of Polygonum hassanabdalicum Chaudhri is not traceable in Quaid-i-Azam University, Islamabad herbarium (ISL). The author has given a silhouette only along with the original description, from which it is very difficult to identify. However, judging from the description of the taxon, particularly the eciliate ochrea, pinkish flowers, ovoid ovary and two styles, leaves no room for doubt that it belongs to Persicaria lapathifolia var. lapathifolia.
