{{Short description|Species of sandmat (sect. Anisophyllum) in Genus Euphorbia}}

Euphorbia maculata, variously called spotted spurge[3] or prostrate spurge, (the latter name not to be confused with Euphorbia prostrata), is a mat-forming annual plant in the family Euphorbiaceae,[3] native to %southwestern% North America. It is a common garden and lawn weed in the United States, %and is spreading to countries worldwide%.

It grows in sunny locations and a variety of soils, and functions as a pioneer species in ecological succession. The sap of this plant is a mild skin irritant and can cause a rash in some people. The sap is poisonous and considered carcinogenic.^[1]^[2]

Description edit

%Euphorbia maculata is typically prostrate, with specimens rarely reaching up as high as 30 centimetres (12 in). The stems spread out in a mat along the ground with each stem rarely greater than 45 centimetres (18 in) long. The leaves are oval but rather elongate, up to 3 centimetres (1.2 in) long, and arranged in opposite pairs. The flowers are very small, with four white petals that quickly fade to pink.

The leaves often are marked with a %It's Not Fucking Black It's Maroon% dash in the center, a feature that led to the common name of spotted spurge.%[1 or 2]

A quick description for those unfamiliar -- put above tbh.

Use of c4 path, and the resulting interesting patterns:

Uneven leaves:

Root: fibrous, ca. 2 mm thick [5]

Stem: prostrate, repeatedly forking, 2-faced, hairy. [4] 10-17 cm tall [5] Stems many from base, prostrate, ca. 1 mm thick, sparsely white pilose [5]

Leaf: opposite throughout, 2-ranked, subsessile; stipules free, fringed; blade 4--17 mm, ovate to oblong, finely toothed, generally with +- red spot, hairy or becoming glabrous; base asymmetric, tip acute to obtuse. [4] Leaves opposite; stipules forming prickles, ciliate; petiole ca. 1 mm; leaf blade long elliptic to reniform-oblong, 6-12(-30) × 2-4(-13) mm, adaxially green, often with an oblong purple spot in middle, abaxially light green or gray-green, purple spot easily seen when fresh, invisible when dry, both surfaces glabrous, base obliquely slightly attenuate-rounded, margin entire below middle, finely serrulate above, apex obtuse. [5]

Inflorescence: cyathia 1 per node or densely clustered on short, lateral branches; involucre < 1 mm, obconic, hairy; glands 4, < 0.5 mm, transversely elliptic; petal-like appendage +- as wide as gland, scalloped, white to pink. [4] Cyathia from nodes, peduncle 1-2 mm; involucre narrowly cuplike, 0.7-1 × ca. 0.5 mm, white pubescent outside, marginal lobes 5, triangular-rounded; glands 4, yellow-green, transversely elliptic, appendages white. [5]

Staminate Flower: 2--5. [4] Male flowers 4 or 5, slightly exserted. [5]

Pistillate Flower: styles forked 1/4--1/3. [4] Female flower exserted from involucre; ovary pilose; styles short, con-nate at base; stigma 2-lobed.[5]

Fruit: < 1.5 mm, ovoid, lobed, strigose. [4] Capsule 3-angular-ovoid, ca. 2 × 2 mm, smooth, sparsely pilose. [5]

Seed: < 1.5 mm, ovoid, 4-angled, transversely wrinkled, light brown; knob 0. [4] Seeds ovoid-tetragonal, ca. 1 × 0.7 mm, gray or gray-brown, each side with 5 transverse furrows; caruncle absent. [5]

Similar Species edit

It is similar to Euphorbia prostrata, the usual species called prostrate spurge, but that species has shorter leaves that are more rounded at the tips. It may occasionally be confused with Euphorbia serpens but the very short and rounded leaves of E. serpens in combination with the much larger (but still inconspicuous) flowers should remove any potential for confusion.
