Systematics and Evolution

摘要: John Ray in his Historia Plantarum (1686–1704) was the first botanist to recognize cotyledon number as a useful means of subdividing flowering plants (Bancroft 1914). Although Linnaeus Philosophia Botanica (1751) did not explicitly mention this distinction between monocotyledons and dicotyledons, it taken up by all later botanists. In most angiosperm classifications from Jussieu (1789) Engler Prantl (1887–89), were arranged position intermediate nonangiosperms indicating lower level organization for than dicotyledons. However, with spread phylogenetic thinking, ranalean origin suggested (e.g., Bessey 1893), Wettstein’s (1901–1907) textbook acknowledge derived treating them after
