  • drag the background to reposition the tree
  • drag a node to ‘re-shape’ the tree presentation
  • click on a node to expand the next clade
  • hover over a ‘leaf node’ to show the families within that order


  • Zoom — into or away from parts of the tree
  • Rotate — move the tree clockwise or anti-clockwise
  • Locality — number of nodes shown around the current node
  • Back — navigate back to previous cladogram (if any)


It helps to do three things when using the Phylogeny Browser:

  1. resize the browser window to occupy the full height and half the width of your screen
  2. use the browser window scroll bar to position the java applet fully in the window
  3. select the Locality drop-down button and move the slider to the right 2 or 3 steps. (The focus of the tree doesn't change until a node is selected.)

Hovering over named nodes is finnicky and needs a slow and steady hand. A dialog box will be displayed listing the families within that order — the active names are WA families and when clicked on will load a new browser window with FloraBase data. Likewise the three icons linking to external resources.

Move and resize this new window to occupy the other half of the screen. Subsequent queries will pop up in that window.
