Anthophyta - Wikipedia
网页The anthophytes are a paraphyletic grouping of plant taxa bearing flower-like reproductive structures. The group, once thought to be a clade, [1] contained the angiosperms – the extant flowering plants, such as roses and grasses – as well as the Gnetales and the extinct Bennettitales. [1]

网页2008年6月28日 · Analyses of morphological and molecular data reveal a revised “anthophyte clade” consisting of the fossils glossopterids, Pentoxylon, Bennettitales, and Caytonia as sister to angiosperms. Molecular estimates of the age of crown group angiosperms have converged on 140–180 million years ago (Ma), older than the oldest fossils (132 Ma ...

网页2007年12月20日 · The ‘anthophyte theory’, the dominant concept of the 1980s and 1990s, has been eclipsed; Gnetales, previously thought to be closest to the angiosperms, are related instead to other extant ...

网页2009年4月3日 · In the mid-1980s, Peter Crane, now at the University of Chicago in Illinois, proposed a solution, the anthophyte hypothesis. Using several lines of evidence and noting that both Bennettitales and Gnetales organize their male and female organs together in what could be construed as a preflower, he considered them, along with angiosperms, as ...
网页The resulting group (Bennettitales, Gnetales and angio sperms, plus Pentoxylon in some analyses) has been termed the 'anthophytes', to emphasize their shared possession of flower like reproductive...
