Asclepias viridis is a species of milkweed, a plant in the dogbane family known by the common names green milkweed, green antelopehorn and spider milkweed.(1) (2) The Latin word viridis means green. The plant is native to the midwestern, south central and southeastern United States, as well as to the southeastern portion of the western United States. A. viridis is a perennial forb with alternately arranged leaves. The inflorescence is an umbel of white flowers with purplish centers. Its root system is a taproot, like that of butterfly weed (A. tuberosa). A. viridis grows on many types of soil. It is common in overgrazed pasture land and roadsides.

09Environmental DNA3 detections
Where the DNA of Asclepias viridis was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
