  Freudenstein, John V. and Elizabeth M. Harris.*   (Site not responding. Last check: 2007-11-02)
The anther is the source of several of the principal characters traditionally used for classification in Orchidaceae, particularly in Epidendroideae, where the greatest amount of variation is present.
An important question is whether the incumbent anther in Vanilloideae is distinguishable from that in Epidendroideae, as the shared possession of an incumbent anther is the key feature that unites the two groups, in disagreement with molecular patterns that suggest that they are not closely related.
The anther in the vandoid subset of Epidendroideae is shown to be truly incumbent, with the bending achieved by a redirection of growth in very early ontogenetic stages, as opposed to the inflexing of a nearly fully-formed anther, as in the remainder of Epidendroideae.

Trees from individual gene matrix analyses are generally congruent in terms of intersubfamilial and intertribal relationships, but vary in overall resolution, bootstrap support for particular clades, and especially for relationships among the genera of Epidendroideae.
Epidendroideae and most of its tribes are monophyletic.
The subfamily is sister to Orchidoideae (which includes the spiranthoid orchids); Cypripedioideae is sister to this pair of monandrous subfamilies.

Tribal level groups are apparent, and jackknife analysis indicates that while most of these groups are well supported, the relationships among them often are not.
This is particularly true among groups within Epidendroideae, where branch lengths are typically short.
This is the same pattern seen in other molecular and morphological data sets and is interpreted to reflect a rapid radiation of epidendroid groups.

Epidendroideae comprise approximately 80% of the species of Orchidaceae.
The subfamily includes much of the variation that is found in anther characters, traditionally the most important in orchid classification.
In order to resolve the relationships of the major clades at the base of the subfamily, which are confounded by short branch lengths that may reflect rapid radiation, additional focused sampling is needed.

 Higher-level orchid research
A primary objective was to see how much structure and character support were implied by morphology, and whether these data justified the elaborate classifications for the family that have been erected in the past.
Orchidoideae, when the southern hemisphere Diurideae are included and the spiranthoid groups are not, are paraphyletic however, since the spiranthoid groups have been derived from them.
Again, detailed study of development is expected to give a refined definition of character states for the Epidendroideae, where additional resolution is sorely needed.

 Project description   (Site not responding. Last check: 2007-11-02)
The use of a mitochondrial locus, the nad1b-c intron, was demonstrated across the family and this locus was used as a case study for examining indel coding.
These studies at lower taxonomic ranks are challenging a number of long-held ideas regarding evolution and classification of Orchidaceae at the species and genus levels, even though the overall picture of phylogenetic relationships within and among orchid subtribes, tribes, and even subfamilies remains unclear.
For example, Freudenstein and Williams have been funded by NSF to investigate relationships within the largest orchid subfamily, Epidendroideae, and continue to address this and related issues by increasing taxonomic sampling and data collection.

Vanilloideae lack both pollinia and viscidia, while both are present in Epidendroideae and Orchidoideae.
Indeed, although Orchidaceae are diverse, note that they are sister to the rest of Asparagales (6,850 species), and Asparagales are sister to commelinids, with some 22,750 species.
Indeed, support for branching along the spine of Epidendroideae is not strong (e.g.
