Montia linearis (Douglas) Greene View in CoL [ Montiaceae ]

Montia linearis is reported as new to the Indiana portion of the Flora of the Southeastern United States coverage area based on a collection made in 2022 (Dearborn County) by Scott Namestnik and Jason Larson. It was found growing abundantly in an agricultural field below stubble from the previous year. Scott Namestnik, Lindsay Namestnik and Cooper T. Namestnik collected the only other Indiana records of M. linearis in April and May 2019 in St. Joseph County ( Consortium of Midwest Herbaria 2023). Although this report from Dearborn County documents the only known occurrence of M. linearis in southern Indiana, it is expected that it will be found in agricultural fields and lawns elsewhere in the southern part of the state.

This branching ephemeral herbaceous plant with alternate, succulent leaves and flowers with five white petals subtended by sepals over 3 mm long is found as a native plant throughout much of the western fifth of North America; it has a scattered distribution as an introduction in the eastern part of the United States, being most common in the southeast ( Kartesz 2015; Weakley & Southeastern Flora Team 2022a). It is globally secure (G5) and secure in Canada (N5), but its status in the United States has not been determined (NNR). In Indiana M. linearis is being treated as introduced and thus it does not have a conservation status rank (SNA).
