Phylogenetics

This study expands our previous work on subtribes Maxillariinae, Oncidiinae, Zygopetalinae, and Stanhopeinae.


Phylogenetic trees for tribe Maxillarieae (= synonym Cymbidieae) and subtribes Maxillariinae, Oncidiinae, and Zygopetalinae are available here along with a non-phylogenetic visualization of the genera of Orchidaceae arranged by subtribe. The generic visualization is presented with FreeMind software, which has specific hardware and software requirements. FreeMind has worked on all of the Windows machines we have tried it on with Windows 7 with Internet Explorer and Firefox, on Macintosh with Safari and Chrome but not with Internet Explorer (Apple stopped supporting Internet Explorer some time ago), and on Linux machines running Ubuntu. If it does not run on your computer, please let me know, stating the browser and operating system you are using.

This is a taxonomically, not phylogenetically, arranged visualization of all the genera of the Orchidaceae, following Genera Orchidacearum, published by Oxford University Press [except for tribe Vandeae (subtribes Adrorhizinae, Aeridinae, Agrostophyllinae, Angraecinae, and Polystachyinae) and tribe Dendrobieae (Bulbophyllum, Dendrobium), coming mid-2013, if all goes according to plan]. For the present, I follow Dressler, 1993, in listing the genera of tribes Vandeae and Dendrobieae and their subtribes. If you click on the red arrow to the left or right of the generic name, it should (slowly, it takes a few seconds for the window to open) show a photo of a representative species of that genus, or a link to a specimen, at least for most Oncidiinae, most Maxillariinae, most Stanhopeinae, all Coeliopsidinae, some Zygopetalinae, as well as scattered genera from other groups.

Genera Orchidacearum uses tribe Cymbidieae to include Maxillarieae and they make a good case for it - it was already used in the key to tribes.


FreeMind Visualization of Genera of Orchidaceae



This will take you to the FreeMind depiction of the family, where you can click to expand any group. It takes a few seconds for the image to load. If you want to search for a particular genus, there is a small box in the upper left hand corner where you can type the name of the genus and it will take you directly to that generic name. Unfortunately, if you type Orchis (or any smilar grouping of letters that is part of another generic name) it will take you to the first occurence of that string of letters, in this case to Erythrorchis, then by using Find Next in the EDIT menu to each subsequent grouping of those letters, until you finally get to Orchis. Or you can just hit the ENTER key over and over to get to Orchis.

The current thinking on phylogenetics of subtribe Maxillariinae is best shown on the web site MAXILLARIINAE and the best phylogenetics of subtribe Oncidiinae are given in the cladograms listed at the bottom of this page.

MAXILLARIEAE - phylogenetic chart and discussion. Click on the PHYLOGENETICS link and scroll down and see our discussion of PHYLOGENETICS OF SUBTRIBE MAXILLARIINAE.

ONCIDIINAE - phylogenetic chart and discussion. This is actually a part of the Maxillarieae page, so don't let the top header confuse you. This was developed before the current web site and is somewhat out of date now. See the cladograms listed at the bottom of this page for the latest results.

ZYGOPETALINAE - phylogenetic chart and discussion. This is actually a part of the Maxillarieae page, so don't let the top header confuse you. This was developed before the current web site and is somewhat out of date now.

More links to phylogenetic works will be added as they are ready.

GENERA OF ORCHIDACEAE ARRANGED BY SUBTRIBE - this is a taxonomically, not phylogenetically, arranged visualization of all the genera of the Orchidaceae, following Genera Orchidacearum, published by Oxford University Press [except for tribe Vandeae (subtribes Adrorhizinae, Aeridinae, Agrostophyllinae, Angraecinae, and Polystachyinae) and tribe Dendrobieae (Bulbophyllum, Dendrobium), coming mid-2013, if all goes according to plan]. For the present, I follow Dressler, 1993, in listing the genera of these tribes (Vandeae and Dendrobieae) and their subtribes. If you click on the red arrow to the left or right of the generic name, it should (slowly, it takes a few seconds for the window to open) show a representative species of that genus, or a link to a specimen, at least for most Oncidiinae, most Maxillariinae, most Stanhopeinae, all Coeliopsidinae, some Zygopetalinae, as well as scattered genera from other groups.
