Seed coat morphology of Aizoaceae–Sesuvioideae, Gisekiaceae and Molluginaceae and its systematic significance

“…The detection of betalains in Gisekia L. reflects its close affinities to Phytolaccaceae, a placement also supported by rbc L/ mat K data (Cuénoud et al ., 2002). As a result, Gisekia can be separated from non-pigmented genera ( Limeum L.) and the other genera of Molluginaceae containing only anthocyanins (Mabry, Behnke & Eifert, 1976;Takhtajan, 1980;Brown & Varadarajan, 1985). Some authors treated Gisekia as a tribe (Gisekieae) in Aizoaceae (Müller, 1909;Pax & Hoffmann, 1934).…”

Conspectus of Aizoaceae, Gisekiaceae and Molluginaceae of Egypt and the Sudan

“…pseudopaniculata JEFFREY, but as it was not possible to distinguish two groups in the material, the concept of HOSNY (2000) is adopted here. The elevation of Gisekia to family rank was first suggested by NAKAI (1942), but for a long time, the position of Gisekia remained a matter of debate and Gisekia was sometimes associated with the Molluginaceae (e.g., HUTCHIN-SON 1959;ECKARDT 1964;HOFMANN 1973;TÄCKHOLM 1974), the Aizoaceae (MÜLLER 1908;PAX & HOFMANN 1934;TÄCKHOLM 1956), or the Phytolaccaceae (HEIMERL 1889;MABRY et al 1976;TAKHTAJAN 1980;BROWN & VARADARAJAN 1985). From the first family, Gisekia differs in having betalains , from the second in lacking bladder cell idioblasts, and from the third in the possession of seemingly lateral cymes.…”
