- Comments
- A native of Asia, Murdannia nudiflora was discovered new to Virginia in 2025, occurring as a lawn weed in two different urban areas. The species is now present in the tropical and warm temperate regions of the Americas. The Virginia populations are the northernmost known in North America and among the northernmost known in the world. Flowers are only open for several hours in early to mid afternoon, so this species blends in well with neighboring lawn grasses and is likely more widespread than the map indicates. This annual seemingly spreads readily via lawn equipment and will likely become an occasional nuisance weed in suburban lawns as it has in much of the southeastern United States.
- Habitat
- The Henrico occurrence grows in a frequently maintained, irrigated lawn adjacent to a suburban stormwater retention pond in the Twin Hickory neighborhood of northwest Henrico County. The James City County population grows among other lawn weeds like Torenia crustacea, Hydrocotyle sibthorpioides, Phyllanthus urinaria ssp. urinaria, and Cyperus brevifolioides.
