This does the job, but is really really slow...

[c:\temp]type test.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<Genus>
<Species>
         <Specie href="Pf000362.htm">A. ampliceps</Specie>
         <Specie href="Pf000363.htm">A. bivenosa</Specie>
</Species>
<Synonyms> A. ampliceps makes with A. bivenosa a
      complex which also includes A. ligulata, A. salicina and A.
      sclerosperma although the latter three are morphologically quite
      different from the former two and also quite distinct from one
another.
</Synonyms>
</Genus>

Hope this helps you to come up with a better solution - or just to prove
that you can write faster stylesheets than I can
