These analyses divide the family into five primary monophyletic clades: apostasioid, cypripedioid, vanilloid, orchidoid, and epidendroid orchids, arranged in that order. These clades, with the exception of the vanilloids, essentially correspond to currently recognized subfamilies. A distinct subfamily, based upon tribe Vanilleae, is supported for Vanilla and its allies. The general tree topology is, for the most part, congruent with previously published hypotheses of intrafamilial relationships; however, there is no evidence supporting the previously recognized subfamilies Spiranthoideae, Neottioideae, or Vandoideae. Subfamily Spiranthoideae is embedded within a single clade containing members of Orchidoideae and sister to tribe Diurideae. Genera representing tribe Tropideae are placed within the epidendroid clade. Most traditional subtribal units are supported within each clade, but few tribes, as currently circumscribed, are monophyletic. Although powerful in assessing monophyly of clades within the family, in this case rbcL fails to provide strong support for the interrelationships of the subfamilies (i.e., along the spine of the tree). The cladograms presented here should serve as a standard to which future morphological and molecular studies can be compared.10aMolecular Phylogeny10aOrchidaceae1 aCameron, Kenneth, M1 aChase, Mark, W1 aWhitten, W., M.1 aKores, Paul1 aJarrell, David1 aAlbert, Victor1 aYukawa, Tomohisa1 aHills, Harold1 aGoldman, Douglas, H  uhttp://www.jstor.org/stable/265693802186nas a2200253   4500008004100000245008800041210006900129260001400198300001400212490000700226520144400233653002401677653001101701100002401712700001901736700002001755700001601775700001901791700001901810700002101829700001801850700002401868856004001892       1999                        eng d00aA Phylogenetic Analysis of the Orchidaceae: Evidence from rbcL Nucleotide Sequences0 aPhylogenetic Analysis of the Orchidaceae Evidence from rbcL Nucl  c1999/02//  a208 - 2240 v863 aCladistic parsimony analyses of rbcL nucleotide sequence data from 171 taxa representing nearly all tribes and subtribes of Orchidaccae are presented here.
