Field Guide to Searsia

We have a rudimentary field guide. Anyone wanting to help with getting it useful is welcome.


What is needed?

  • Tidy up scientific name display;
  • Add in some diagnostics in the text
  • Create a table of feature x species that we can add in to use as a key.

Anyone keen.

Leaf venation in Searsia

Leaflet venation

(from Moffett)
In the description of the taxa, the following terms, after Hickey (1973), are used to describe the various forms of pinnate venation of the leaflets:


secondary veins terminating at the margin.

  • Simple: all of the secondary veins and their branches terminating at the margin.
  • Semi-: secondaries branching just within the margin, one of the branches terminating at the margin, the other joining the superadjacent secondary.
  • Mixed: some of the secondaries terminating at the margin and an approximately equal number of (usually inter-vening) secondaries otherwise.


secondary veins not terminating at the margin.

  • Brochidodromous: secondaries joined together in a series of prominent arches.
  • Reticulodromous: secondaries losing their identity towards the leaf margin by repeated branching into a vein reticulum.
  • Kladodromous: secondaries freely ramified toward the margin.


all but the primary vein absent, rudimentary or concealed within the coriaceous mesophyll.
