Lupinus rivularis
species of plant
Lupinus rivularis is a species of lupine known by the common name riverbank lupine native to North America. It is also commonly known as river lupine, streambank lupine, and stream lupine.
Distribution
Lupinus rivularis is found in western North America, from southern British Columbia to northern California. Specifically, it is native to California, Oregon, Washington, and British Columbia. It mainly exists from coastal habitat in places such as both Olympic and Redwood National Parks, and at Point Reyes National Seashore. Its development in these regions is driven by its preference for sandy, well-drained, and low nitrogenous soils, along with precipitation levels between 20 and 100 inches. Additionally, this species observes optimal growth in environments with full sunlight. Riverbank lupine is able to well establish a population where there is reduced competition, making it an excellent pioneer species for disturbed environments.
Description
This is a robust, erect perennial herb or subshrub growing up to about a meter tall. The long taproot enables its growth in dry soil environments that are typical of disturbed botanical environments.
Begin with the source’s own compact description: “Lupinus rivularis” is species of plant. The dossier treats that line as a proposition to test through Lupinus, rivularis and species, not as a finished interpretation.
Why this record matters
The phrase “species of plant” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 Jul 28, 2026. The linked authority identifier is Q4118449. The Library of Congress control number is sh2017002950. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
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.
