Subfamily Euphorbioideae[edit | edit source]

Tribe Euphorbieae[edit | edit source]

Euphorbia[edit | edit source]

Two subgenera of Euphorbia (commonly known as spurge) can be found in New York.

Euphorbia subg. Chamaesyce[edit | edit source]
Subgenus Chamaesyce contains North American spurges or sandmats, many of which are treated in a separate Chamaesyce genus by some sources. Recent phylogenic studies, however, have shown the Chamaesyce genus to be embedded within Euphorbia.[1]

The name Chamaesyce is from the Greek chamai (meaning "on the ground") and skyon (meaning "fig," as in Ficus). A common pronunciation of Chamaesyce, according to Botanary is kam-ay-SY-kee.[2]

  1. ↑ The New York Flora Atlas states: "Steinmann and Porter (2002) provide strong evidence that the segregate genus Chamaesyce is nested within Euphorbia. Therefore we recognize Euphorbia in a broad sense including Chamaesyce."
  2. ↑ Dave's Garden. Botanary: Chamaesyce

Euphorbia subg. Esula[edit | edit source]

Subgenus Esula contains non-native spurges, a few of which are considered highly invasive in New York.

Euphorbia subg. Esula sect. Esula[edit | edit source]
Euphorbia cyparissias
Section Esula contains two highly invasive and prohibited species, though which two is a little confusing. New York State law (as of 2021) lists Euphorbia cyparissias (cypress spurge) and Euphorbia esula (leafy spurge) as prohibited invasive species.[1]. NYNHP lists those two species with Ecological Invasiveness Ranks of High and NY State Tier 4.[2] However Flora of North America claims that the invasive leafy spurge previously known in North America as Euphorbia esula is actually Euphorbia virgata and that Euphorbia esula is in fact a relatively rare non-invasive introduction to North America.[3] The New York Flora Atlas has subsequently moved all New York State Euphorbia esula records to Euphorbia virgata and listed Euphorbia esula as excluded.[4]
