species
This is an auxiliary template for use in ((Speciesbox)) (and perhaps others). It has no direct use. Its purpose in that context is to select a specific epithet from the first of the three possible parameters which contain it.
Examples of usage, assuming that it is used from a page whose name is "Quercus robur":
((select species|robur|Quercus robur|((PAGENAMEBASE)) ))
=> robur
((select species||Quercus robur|((PAGENAMEBASE)) ))
=> robur
((select species|||((PAGENAMEBASE)) ))
=> robur
Typically in ((Speciesbox)) it will be used in the following way, to select the first non-empty string obtained from the value of the species
parameter, the value of specific epithet of the taxon
parameter and the value of the specific epithet of the page name.
((select species|(({species|))|(({taxon|))}|((PAGENAMEBASE)) ))
