Borreria shandongensis F. Z. Li & X. D. Chen; Diodella teres (Walter) Small; Spermacoce shandongensis (F. Z. Li & X. D. Chen) Govaerts.
Herbs, annual, erect, to 30[-50] cm tall; stems somewhat flattened to slightly [or sharply] 4-angled, pilosulous [and/or pilose to glabrescent]. Leaves sessile; blade drying papery, linear-lanceolate, [8-]20-40 × [1-]3-5[-7] mm, both surfaces hispidulous, base obtuse [to rounded or subcordate], margin weakly [to strongly] revolute, apex acute to acuminate; secondary veins indistinct; stipule sheaths truncate, 1-2.5 mm, pilosulous to glabrescent, with 5-9 setae 1-7 mm. Flowers 1[-3] per axil or 1[-6] per node; bracts reduced. Calyx pilosulous to glabrescent; ovary portion obovoid, 0.5-0.8 mm; limb deeply lobed; lobes lanceolate, ca. 1 mm, pilosulous to glabrescent. Corolla pink [to pale purple or blue], funnelform, hispidulous to glabrescent outside; tube [1.5-]4[-7] mm, glabrescent inside; lobes elliptic-oblong, 0.5-2 mm. Fruit obovoid, [1.5-]3-3.5 mm, papery to bony, hispid to hispidulous, separating into 2 mericarps each with a Y-shaped sulcus on adaxial surface; seeds ca. 2.5 mm, yellowish brown when dry, longitudinally 1-grooved. Fl. and fr. Aug-Sep.
Disturbed, often degraded open ground. S Fujian (Jinmen), Shandong (Qingdao) [native to Antilles and North and South America; adventive in N Africa, Japan, Korea, and Madagascar].
Diodia teres has not been widely reported previously from Asia, but it is known from Japan (Honshu, 18 Oct 1995, S. Tsuagaru & G. Murata 22898, MO!) at a similar latitude to its occurrence in China and probably should be expected elsewhere.Diodia teres has not been widely reported previously from Asia, but it is known from Japan (Honshu, 18 Oct 1995, S.
