State Protection
Threatened
Listed as Threatened by New York State: likely to become Endangered in the foreseeable future. For animals, taking, importation, transportation, or possession is prohibited, except under license or permit. For plants, removal or damage without the consent of the landowner is prohibited.
Federal Protection
Not Listed
State Conservation Status Rank
S2
Imperiled in New York - Very vulnerable to disappearing from New York due to rarity or other factors; typically 6 to 20 populations or locations in New York, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines.
Global Conservation Status Rank
G4?
Apparently Secure globally (most likely) - Conservation status is uncertain, but most likely uncommon in the world but not rare; usually widespread, but may be rare in some parts of its range; possibly some cause for long-term concern due to declines or other factors. More information is needed to assign a firm conservation status.

Summary

Did you know?

This plant was named for 19th-century Prussian botanist and pharmacist Wilhelm Stuwe (Haddock 2010).

State Ranking Justification

There are nine existing populations but only three of them are large. There are 25 historical occurrences, mostly in Nassau and Suffolk counties on Long Island but many of these have probably been extirpated.

Conservation and Management

Threats

The succession of the open grassland habitat to more woody plants is a threat.

Conservation Strategies and Management Practices

The open habitat needs to be maintained in an open canopied state but the plants should not be disturbed during the growing season.

Research Needs

There are no research needs known at this time.

Habitat

Habitat

In New York it grows mainly in disturbed openings dominated by grasses and wildflowers within pitch pine scrub oak barrens, pitch pine oak woods and coastal oak hickory woods. It can often be along trails or roadsides within these woodlands (New York Natural Heritage Program 2012). Dry upland woods and barrens (Gleason and Cronquist 1991).

Associated Ecological Communities

  • Pitch pine-heath barrens (guide)
    A shrub-savanna community that occurs on well-drained, sandy or rocky soils. The most abundant tree is pitch pine and the shrublayer is dominated by heath shrubs.
  • Pitch pine-oak forest (guide)
    A mixed forest that typically occurs on well-drained, sandy soils of glacial outwash plains or moraines; it also occurs on thin, rocky soils of ridgetops. The dominant trees are pitch pine mixed with one or more of the following oaks: scarlet oak, white oak, red oak, or black oak.
  • Pitch pine-oak-heath woodland (guide)
    A pine barrens community that occurs on well-drained, infertile, sandy soils. The structure of this community is intermediate between a shrub-savanna and a woodland. Pitch pine and white oak are the most abundant trees.
  • Pitch pine-scrub oak barrens (guide)
    A shrub-savanna community that occurs on well-drained, sandy soils that have developed on sand dunes, glacial till, and outwash plains.

Range

New York State Distribution

The largest number of populations occur on Long Island and Staten Island where it is currently known from Staten Island and Suffolk County on Long Island. There are historical records north along the Hudson Valley to Washington County and one record in the Southern Tier in Tioga County. There is also an unconfirmed report from Erie County.

Global Distribution

This is a plant of the southeastern and central US. It extends to the states of the Northeast where it is rare except in the southern New England states of Massachusetts, Rhode Island, and Connecticut.

Identification Comments

General Description

Velvety bush-clover is a perennial that grows erect as either a simple stem or a stem branched towards the top. It grows to about 1 meter tall and the stem is covered with soft hairs that stand out. The leaves are on short petioles and have 3 elliptic leaflets. The largest leaflets are 1.5-3.5 cm long, hairy above and densely velvety below. The purple flowers are in dense racemes in the upper axles of the leaves on peduncles that are shorter than the leaves. The flowers are 6-8 mm long. The upper two sepals-lobes are not joined together or only slightly joined at the base. The fruit is densely hairy (Gleason and Cronquist 1991).

Identifying Characteristics

Distinguishing characteristics: leaves wooly or velvety with spreading hairs, beneath; calyx lobes 1.7-3.5 mm, the 2 uppermost connate less than half their length and not extending to the middle of the fruit, fruit velvety. Best life stage for ID: in fruit. Characteristics needed to ID: leaves and fruit.

Best Life Stage for Proper Identification

The best time to identify this plant is when it is in flower or fruit.

Similar Species

Lespedeza virginica and Lespedeza intermedia are closely related and much more common but the undersides of their leaves are not densely velvety but only with long hairs that are appressed to the leaves. The upper two sepals-lobes are joined together at least half of their length. Their fruits are somewhat hairy but not densely hairy (Gleason and Cronquist 1991).

Best Time to See

The plants flower beginning in August. Fruits develop in September and are visible through October.
