Comments

Taxonomy
There is considerable disagreement as to the proper classification of the species and subordinate taxa of leafy spurge.

The Plant List36 identifies one variety and two subspecies, including Euphorbia esula subsp. tommasiniana.

GRIN38 lists two subspecies, including Euphorbia esula subsp. tommasiniana, and a subspecies-level hybrid (nothosubsp).

USDA PLANTS3 lists two subspecies, the nominate subspecies and Euphorbia esula var. uralensis.

ITIS37, the first authority I look to for taxonomic nomenclature, considers all subspecies and varieties invalid synonyms of Euphorbia esula.

The Minnesota DNR (MNTaxa28) is not a taxonomic authority but its opinion matters to Minnesotans who research native plants. MNTaxa lists Euphorbia esula with no subspecies but it also lists Euphorbia virgata (Russian leafy spurge).

Chadde62 lists only Euphorbia virgata (leafy spurge).

By the way, am I the only one that finds the Tree of Life31 project virtually unusable? No species search? Really? This is on a site whose "goal is to contain a page with pictures, text, and other information for every species and for each group of organisms, living or extinct."
