Plantago cordata Troy Weldy
Family: Plantain Family (Plantaginaceae)

State Protection: Rare
listed species have: 1) 20 to 35 extant sites, or 2) 3,000 to 5,000 individuals statewide.

Federal Protection: Not Listed

State Rarity Rank: S3
A State Rarity Rank of S3 means: This plant is rare in New York (typically 21-50 populations, limited number of individuals, or limited range).

Global Rarity Rank: G4
A Global Rarity Rank of G4 means: This species is apparently secure globally (typically with more than 100+ populations), though it may be quite rare in parts of its range, especially at the periphery.

Did you know?
New York has more populations of this plant than any other state. It was only known from the tidal marshes along the Hudson River until the 1990s when a population was found along a stream in western New York. During river flooding and high tides, these plants may be submerged completely for long periods of time. The specific name refers to its heart-shaped leaves.

State Ranking Justification [-]
There are nearly 30 known populations and sub-populations scattered along the freshwater tidal areas of the Hudson River, with a few disjunct populations in western New York. Many of these populations have fewer than 40 individuals, but at least three have more than 1,000 plants. There are some threats associated with this plant, but none are expected to have immediate or severe impacts. New York and Missouri share the greatest responsibility in ensuring the long-term protection of this unique Plantago.
