Lepidium montanum is a species of flowering plant in the mustard family known by the common names mountain pepperweed, mountain peppergrass, mountain pepperwort, and mountain pepperplant. It is native to western North America from Oregon to Montana to northern Mexico, where it can be found in a number of habitats, often on salty or gravelly soils. There are several varieties, many of which are difficult to distinguish.
Description
This is a short, spreading, shrublike biennial herb producing a rounded form up to about 40 centimeters tall and greater in width. The leaves near the base of the plant are up to 15 centimeters long and are divided into several toothed lobes; those further up on the stem are shorter and often undivided. The plant flowers abundantly in rounded to cylindrical inflorescences a few centimeters wide. Each small flower has white to cream-colored petals about 2 millimeters long and two to six stamens. The fruit is an oval-shaped capsule a few millimeters long.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Lepidium montanum”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 9, 2026. The linked authority identifier is Q2716718. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1838.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
