“…In most other conifers the ovules are borne axillary on cone scales (Hart, 1987;Price, 1990;Chaw et al, 1993, and references therein). Because of this distinction, the yew family was historically excluded from the Coniferales, notably by Sahni (1920) and Florin (1948Florin ( , 1951, and was placed in its own order, Taxales. However, proembryogeny (Doyle, 1963;Singh, 1978;Dogra, 1980), chemical (Heagnauer, 1988), morphological (Hart, 1987), and molecular (Raubeson and Jansen, 1992;Chase et al, 1993;Chaw et al, 1997;Stefanovic et al, 1998) data accumulated later did not provide evidence favoring Sahni or Florin's treatment. Due to the efficacy of taxane compounds in anticancer therapies, taxads have been experiencing a research renaissance.…”
