Source-derived summary

Phacelia crenulata is a species of flowering plant in the waterleaf family, Hydrophyllaceae. Its common names include notch-leaf scorpion-weed, notch-leaved phacelia, cleftleaf wildheliotrope, and heliotrope phacelia. Phacelia crenulata has an antitropical distribution, a type of disjunct distribution where a species exists at comparable latitudes on opposite sides of the equator, but not at the tropics. In North America, it is native to the southwestern United States as far east as Colorado and New Mexico, and Baja California and Sonora in Mexico. In South America, it is native to southern Peru, western Bolivia, and northern Chile.

Editorial summary

The public source identifies “Phacelia crenulata” as species of plant. This brief keeps that definition visible, then builds a research path around Phacelia, crenulata and Species.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 95-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Phacelia, crenulata and Species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Phacelia crenulata”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.

Evidence profile

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 Sep 18, 2026.

Critical limits

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.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
