Kitten Tails (Besseya bullii)


Life history

Species overview

Kitten Tails (Besseya bullii), a State Threatened plant, is found commonly in small woodland openings, or near bluff edges. Blooming occurs late May through late June; fruiting occurs late June through late August. The optimal identification period for this species is late May through late August.

Synonyms: Gymnandra bullii, Synthyris bullii, Wulfenia bullii

Identification

  • Distinguishing characteristics: Basal leaves long-petioled, egg-shaped, palmately veined, with toothed margins; flowers small, yellow, born in a tall, erect spike.
  • Flower characteristics: Flowers small, yellow and born at the top of a 5 to 15 cm long spike.
  • Fruit characteristics: 4 to 7 mm long and covered with very small, course, stiff hairs.
  • Leaf characteristics: Basal leaves toothed, palmately veined, egg-shaped, 6 to 12 cm long with long petioles; leaves further up the stem alternate, egg-shaped or oblong, 1 to 2 cm long with no petioles.

Phenology

  • Blooming phenology: late May through late June
  • Fruiting phenology: late June through late August
  • Optimum time to identify: late May through late August

Habitats and landscapes

The Natural Heritage Inventory has developed scores indicating the degree to which each of Wisconsin's rare plant species is associated with a particular natural community or ecological landscape. This information is similar to that found in the Wildlife Action Plan for animals. As this is a work in progress, we welcome your suggestions and feedback.

General habitat information

  • Habitat description: Found commonly in small woodland openings, or near bluff edges.
  • Soils: Sandy soils.

Natural communities

This table lists the natural communities that are associated with Kitten Tails. Scores for natural community associations are: "significant" association (score=3), "moderate association" (score=2) or the species can be present but is only weakly associated with the community (score=1).

Ecological landscapes

This table lists the ecological landscape association scores for Kitten Tails. The scores (3=High, 2=Moderate, 1=Low, 0=None) also correspond to the map.

Species guidance

The Endangered Resources Program has developed avoidance measures and management guidelines for plants on the Natural Heritage Working List. These are a work in progress, and we welcome your suggestions and feedback. Sources used in developing this information can be found here.

Avoidance measures

These are specific actions designed to avoid "take" (mortality) of this species.

  • Avoid known individual plant locations and conduct operations elsewhere when they are least likely to cause damage. Ideally, this would involve frozen, snow-covered ground. However, in areas of the state where frozen conditions are unreliable, very dry soils late in the growing season might be the best available alternative. Consult with a biologist, if needed.
  • Avoid broadcast spraying of herbicides; use care with spot spraying.

Management guidance

Management guidelines are additional considerations that may help maintain or enhance habitat for this species

  • Maintain and restore open habitat through selective clearing and brushing.
  • Prescribed burns and/or brushing may be beneficial (dependent on local site conditions).

Kittentails (WI Threatened) is more common in Wisconsin than any other place in the world, and it's more common in the southern Kettle Moraine region of the Southeast Glacial Plains than anywhere else in Wisconsin.
