Gypsum Ringstem: A Botanical Overview

This page provides an overview of the Gypsum Ringstem, scientifically known as Anulocaulis leiosolenus var. gypsogenus. This unique plant, adapted to gypsum-rich environments, presents interesting characteristics for plant enthusiasts.

Considerations for Pets

  • Ringstems are described as having "glutinous brown bands," which may be a consideration depending on a pet's behavior.

Considerations for Children

  • Ringstems are described as having "glutinous brown bands," which may be a consideration depending on a child's interaction with the plant.

Nomenclature and Taxonomy

  • Scientific Name: Anulocaulis leiosolenus (Torr.) Standl. var. gypsogenus (Waterf.) Spellenb. &amp T. Wooten
  • Common Names: Gypsum Ringstem, Gyp Ringstem, Pecos Gyp Ringstem, Southwestern Ringstem, Ringstem
  • Family: Nyctaginaceae
  • Synonyms: Anulocaulis leiosolenus var. gypsogenus (Waterfall) - this seems to be an earlier designation, before Spellenberg & Wooten.
  • Rank: Variety

Distribution and Habitat

  • The Gypsum Ringstem is often found in open gypsum outcrops, particularly those of the Yeso Formation with limestone cobble, at elevations around 1,350-1,450 meters (4,425-4,750 feet).
  • Geographic range is restricted to gypsum-rich soils along the Pecos River.
  • It is considered a gypsum endemic (gypsophile), meaning it's restricted to gypsum soils.
  • Specific locations include southern New Mexico and areas around Lake Mead.

Morphological Characteristics

  • Gypsum Ringstem is described as a Forb/herb and a perennial plant.
  • Ringstems are thickly-rooted.
  • The plant has perianth measuring 25-35.

Ecological Role

  • It is a gypsum endemic plant, adapted to survive in soils with high gypsum content.
  • Its presence can indicate specific soil compositions and environmental conditions.

Quirky Facts

  • The Sticky Ringstem, a related variety, has flowers that bloom at night.
  • Ringstems are known for having glutinous brown bands at their stem internodes.

Interactions with Other Organisms

  • The plant is known to interact with other gypsum-endemic species like Las Vegas bearpoppy.
  • A study mentions mesquite/acacia communities and their relationship to gypsum badlands where Sticky Ringstem thrives.
