Lophocereus schottii
species of plant
Lophocereus schottii, the senita cactus, is a species of cactus from southern Arizona and north-western Mexico, particularly Baja California and Sonora.
Description
Lophocereus schottii grows tree-shaped to shrub-like with yellow-green, more or less upright shoots, which often develop into thickets with more than 100 shoots. It reaches heights of 1 to 3 meters and shoot diameters of 5 to 10 cm (2.0 to 3.9 in). A tribe is rarely formed. There are 4 to 13 clearly defined ribs. The 1 to 3 strong, gray central spines are 1 to 3 cm (0.39 to 1.18 in) long. The 3 to 5 marginal spines are gray and 0.5 to 1.5 cm (0.20 to 0.59 in) long. The terminal pseudocephalium consists of bristly, flexible, gray spines. It occasionally grows to be more than 100 cm (39 in) long.
The funnel-shaped flowers appear laterally from the pseudocephalium and open at night.

Why this record matters
“Lophocereus schottii” is worth following because a concise public description often conceals a longer documentary argument. Here, Lophocereus, schottii and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 4, 2026. The linked authority identifier is Q15320987. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
