Definition
Cochemiea thomasii is a taxonomic name referring to a species of cactus in the family Cactaceae.
Overview
The genus Cochemiea comprises terrestrial, stem‑succulent cacti primarily distributed in arid and semi‑arid regions of Mexico and the southwestern United States. Species assigned to this genus are generally small, globular to short‑columnar, and possess characteristic tubercles, spines, and often conspicuous flowers. The exact geographic range, habitat preferences, and conservation status of Cochemiea thomasii have not been fully documented in widely accessible scientific literature.
Etymology / Origin
The specific epithet thomasii is a patronym, conventionally formed to honor an individual bearing the name Thomas (or a similar variant) who is presumed to have been associated with the plant’s discovery, collection, or description. The genus name Cochemiea derives from a combination of Greek roots referring to “shell” (kokho meaning “shell”) and “moss” (chēmeia), reflecting aspects of the plant’s morphology as interpreted by the authors who erected the genus.
Characteristics
While detailed morphological data for Cochemiea thomasii are not presently available in major botanical references, typical traits of Cochemiea species include:
- Growth form: Small, solitary or clumping stems, usually globular to slightly elongated.
- Stem surface: Covered with tubercles bearing areoles from which spines arise.
- Spines: Variable in number, length, and coloration; often arranged in a radial and central pattern.
- Flowers: Usually produced near the stem apex; funnel‑shaped, often yellow, pink, or white, opening during the day.
- Fruit: Fleshy, berry‑like, containing numerous seeds.
Accurate information about the specific size, spine arrangement, flower color, phenology, and ecological requirements of C. thomasii is not confirmed.
