Description
It has tree-shaped columnar trunks that grow slowly to 12 feet (3.7 m) and may reach 20 feet (6.1 m) in height, rarely branching. Stems are 3 to 4 inches (7.6 to 10.2 centimetres) in diameter, with ribs 4 to 7 in (10 to 18 cm). Its central spine is about 3⁄8 inch (0.95 cm) in diameter with five to 9 radials and slightly yellowish in color. The five to nine marginal spines are 2 to 4 millimeters long. The large areoles on it later merge. The flowering areoles located near the shoot tips are covered with numerous bristles up to 2 centimeters long.
The funnel-shaped, reddish flowers are 3 to 4 centimeters long. Their pericarpel and floral tube are covered with scales that carry wool and bristles in their axils.

Why this record matters
“Marginatocereus marginatus” is worth following because a concise public description often conceals a longer documentary argument. Here, Marginatocereus, marginatus and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Feb 11, 2026. The linked authority identifier is Q15330247. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
