1. Origin of Name:

The genus "Coryphantha" comes from Greek roots—"koryne," meaning "club" or "club-shaped," and "phanes," meaning "showing" or "appearing," referring to the tubercles or protrusions on the cactus. The species name "elephantidens" is derived from Latin, meaning "elephant teeth," describing the plant’s large, tooth-like tubercles that resemble elephant tusks. The cultivar name "Tanshi Zougemaru" is a specific horticultural variety cultivated for its distinctive appearance, often named by cactus enthusiasts or breeders to honor particular traits or origins. This cultivar’s name emphasizes its beauty and uniqueness in cultivated collections.

2. Origin of Plant:

Coryphantha elephantidens cv. Tanshi Zougemaru is a cultivated variety, selectively bred or produced in horticultural collections, often originating from Japan or other regions focused on unique cactus cultivars. While the species is native to Mexico, this particular cultivar was developed for its striking appearance and ornamental appeal, showcasing plant breeding efforts to enhance specific traits.

3. Description:

This cultivar features a compact, globular form typical of Coryphantha, but its most striking trait is its large, prominent, ivory-colored, tooth-like tubercles that resemble tiny elephant tusks. The surface is usually a pale green or bluish-green, with tubercles arranged in a symmetrical pattern around the body.
