6. Gisekia Linnaeus, Mant. Pl. 2: 554, 562 (as Gisechia). 1771.

[For Paul Dietrich Giseke, 1741-1796, German professor, botanist, and pupil of Linnaeus]

Herbs, annual. Leaves opposite or appearing whorled. Inflorescences axillary, compound dichasia, appearing umbelliform. Flowers: sepals 5; stamens 5; carpels 5, free; ovaries 5, each 1-loculed; style and stigma 1 per carpel; stigma terminal. Fruits: group of thin-walled, lenticular achenes. Seed 1 per carpel.

Species ca. 5 (1 in the flora): North America, Eurasia, Africa.

Described as "debatably phytolaccaceous" by G. K. Rogers (1985), Gisekia has been referred also to Aizoaceae, Molluginaceae, and even Portulacaceae---and, perhaps the best solution, to its own family, Gisekiaceae.

The generic name is sometimes misspelled as "Giesekia."
