Summary

Did you know?

Golden club really has a split personality when it comes to habitats. It occurs in two very different wetland habitats in New York; in freshwater intertidal mud flats and marshes and also in the peat moss of a few shrub bogs. This is the only species in the genus and, unlike the related jack-in-the-pulpit, this genus has only a Jack and no pulpit! The starch in the rhizomes and seeds is edible once it is boiled (Mabberley 1987).

State Ranking Justification

There are 13 existing populations but only two of these are in Sphagnum bogs and not in freshwater tidal areas. About half of the populations are in good to excellent condition. There are seven historical records from Long Island that are probably extirpated.

Short-term Trends

Short-term trends are good as existing populations have not seen a decline over the last 20 years.

Long-term Trends

There has been a decline in populations on Long Island as the area has been developed but most of the historical records from the 20th-century continue to exist today along with some new discoveries.

Conservation and Management

Threats

Hudson river populations are threatened by the spread of Phragmites and water chestnut and by the erosive power of boat wakes. Some bog populations may be threatened by too much visitation.

Conservation Strategies and Management Practices

Establish sufficient buffers around populations to preserve the undisturbed aspect and hydrology of their habitat.

Research Needs

Research is needed to determine why some populations occur in the completely different habitat of Sphagnum bogs while most of the populations occur in freshwater tidal areas of the Hudson River. Habitat parameters should also be determined for the bog populations to understand why this species does not occur in similar habitat in other areas of the state.

Habitat

Habitat

Most known existing sites for Golden Club in New York State are freshwater tidal marshes, swamps, and mudflats. However this species is also found in other quite different Sphagnum-dominated habitats in the state (and elsewhere), such as bogs, poor fens, and coastal plain ponds. Golden Club apparently is tolerant of a wide range of acidity and exposure to light, though all of the sites it is known from are habitats of still, shallow water (New York Natural Heritage Program 2007). Sandy, muddy or peaty shores and shallow water (Fernald 1970). Swamps and shallow water, especially on the coastal plain (Gleason & Cronquist 1991).

Associated Ecological Communities

  • Coastal plain pond* (guide)
    The aquatic community of the permanently flooded portion of a coastal plain pond with seasonally, and annually fluctuating water levels. These are shallow, groundwater-fed ponds that occur in kettle-holes or shallow depressions in the outwash plains south of the terminal moraines of Long Island, and New England. A series of coastal plain ponds are often hydrologically connected, either by groundwater, or sometimes by surface flow in a small coastal plain stream. * probable association but not confirmed.
  • Freshwater intertidal mudflats (guide)
    A sparsely vegetated community characterized by low rosette-leaved aquatics. This community occurs on exposed intertidal mudflats where the water is fresh (salinity less than 0.5 ppt). This community is best developed where mudflats are nearly level so that broad expanses are exposed at low tide. The plants are completely submerged in 0.9 to 1.2 m (3 to 4 ft) of water at high tide and they are usually coated with mud.
  • Freshwater intertidal shore (guide)
    A community of the intertidal gravelly or rocky shores of freshwater tidal rivers and creeks, sometimes occurring at the base of cliffs. The vegetation may be very sparse.
  • Freshwater tidal creek* (guide)
    The aquatic community of a shallow, tidally flooded freshwater creek with submerged areas averaging less than 2 m (6 ft) deep at low tide. * probable association but not confirmed.
  • Freshwater tidal marsh (guide)
    A marsh community that occurs in shallow bays, shoals, and at the mouth of tributaries of large tidal river systems, where the water is usually fresh (salinity less than 0.5 ppt), and less than 2 m (6 ft) deep at high tide. Typically there are two zones in a freshwater tidal marsh: a low-elevation area dominated by short, broadleaf emergents bordering mudflats or open water, and a slightly higher-elevation area dominated by tall grass-like plants.
  • Inland poor fen (guide)
    A wetland fed by acidic water from springs and seeps. Plant remains in these fens do not decompose rapidly and thus the plants in these fens usually grow on older, undecomposed plant parts of mostly sphagnum mosses.

Range

New York State Distribution

Most of the currently extant populations of Golden Club are located in the freshwater tidal areas of the Hudson River, but there are also known extant populations in central New York, and north-central Long Island, and many historical populations from inland within the Hudson Valley and the Long Island and New York City areas.

Global Distribution

Golden Club reaches its northern limit in New York and Massachusetts, and is found mainly along the coast south to Florida and west to Texas, but also inland to Tennessee, Kentucky, West Virginia, and Pennsylvania.

Identification Comments

General Description

Orontium aquaticum is a perennial, rooted aquatic plant growing from stout rhizomes. It has spreading (sometimes reclining or floating), strap-like (6-20 cm long and a third as wide), basal leaves only, these are also parallel-veined. The many bright yellow flowers are borne on the upper portion (2-5 cm) of a single fleshy, erect white stalk (the spadix) 20-40 cm tall.

Similar Species

Orontium aquaticum looks like nothing else in our state.

Best Time to See

Golden Club flowers from mid-April through June, with vegetative leaves and fruits persisting until first frost.
