Description:
Description and Variation: Euphorbia oblongata is a perennial herb, reaching to about three feet tall, from a woody rootstock. Several stems, often hairy when young, arise from a central crown. The leaf arrangement is alternate. The oblong leaves are glabrous (smooth and hairless) with finely toothed margins. Eggleaf spurge is monoecious, with male and female flowers on the same plant. The inflorescence is a cyathium, found in clusters. The glandular bracts below the cyathium are yellow, ovate, and rounded at the base. The whorl of leaves below the flowers are yellowish and oblong and they appear in May, depending on the site. The fruit is a three-lobed capsule. The seed is olive-brown, smooth and shiny. (Hickman 1993; Turner 1995).

• Mechanical: When mechanically cut after flower production, eggleaf spurge will produce a new set of flowering shoots (Turner 1995). Pulling is not a control option. Because of the large tap root, it must be dug out for effective control (Personal conversation with San Juan County coordinator).
• Biological: None known.
• Herbicide: None known. Refer to the State Noxious Weed Control Board site
