Polygonaceae of the island Iki.

By

Kiichi Ohki.

Iki is an island located between Tsusima and Kiusiu. It is considered, equally as the Tsusima, to be the relic of former conti- nent which connected Corea and Japan. No botanist had ever touched this island, though the picturesque landscape of it is renowned among the inhabitants of North-Kiusiu. I have landed on the island last August and collected a lot of plants, especially caring for the Poly- gonaceous plants. The followings are the Polygones found there. I have shown my paper to Prof. NAKAI who was kind enough as to have given many important corrections to it.

XII often caused the misunderstandings of the real subject. Polygonumsagittatuln grows in Western Siberia and the Baical-regions. It is slender unbranched herb with small aculeae on the angles of stem and the basal portion of the Costa. Petioles have only one row of small aculeas. MEISSNER,MAXIMOWICz, KORSCHINSKY and others put much weight on the size of the plant and the colour of the seeds to distinguish PolygonurnSieboldi from P. sagittatuln. But the aculea is more noticeable. The petioles of P. Sieboldi have always 3 rows of aculeas (however imperfect). The aculeas of stem are more rigid and long. The meagre form called var. ftaludosa (KowARovin Acta Horti Petropolitani XXII. p. 132) represents similar form of the real P. sagittatum, yet the aculeas are invariable. The American plant, Polygonurn sagittatuln var. arericanum MEISSNERin de CANDOLLE,Prodronms XIV. p. 132 has longer acicular aculeae on the stems and petioles ; the leaves have acicular hairs along the margine ; the involucral bracts have needle-point. It should be distinguished from both P. sagittatuln and P. Sieboldii as a distinct species Persicaria amerieana OHKI. One more species is found in Japan which flowers from May to June. Messers. T. MAKINOand T. NAKAItook this for P. sagittatuln, but it differs from that by the diffusely branched stem, long-petioled leaves and invalid distant aculeae. It is Persicaria aestiva OHKI, sp. nov. Syn.
