Although not a man who attracted much attention as
a theorizer, Rydberg was an energetic field biologist and meticulous (if
somewhat radical) taxonomist whose efforts made him perhaps the foremost
expert on Rocky Mountain and Great Plains floras. These days his most
cited works are his Flora of the Rocky Mountains and Adjacent Plains
and Flora of the Prairies and Plains of Central North America,
but he also produced several other memorable "floras," as well as numerous
reports and taxonomic reviews--in all, in fact, he is reputed to have
described some seventeen hundred new species. For his later works Rydberg
contributed all his own illustrations.
