The Compleat Botanica contains a checklist of genus names, species epithets, sub-species and varieties. The overwhelming majority of these names are for vascular plants: angiosperms, gymnosperms, spore bearing ferns and their allies.   ......................................

Families exhibit common characteristics that in a subjective sense group them together.   ......................................

The official taxonomic naming convention for families is that they end with -aceae. Only a few exceptions have survived.   ......................................

Inter-generic hybrids are formally identified with a cross symbol prefixing their name.   ......................................

Sometimes the full genus, species, and variety is not known for a specimen.   ......................................
