Source-derived summary

Agrostis exarata is a species of grass known by the common names spike bentgrass, spike bent, Pacific bentgrass, and spike redtop. It is native to western North America from Texas to the Aleutian Islands.

Description

This is a common perennial grass reaching one to three feet in height with long, thin, flat leaves each with a ligule of 2–4 millimetres (0.079–0.157 in).

The tuft inflorescence may be up to 30 centimetres (12 in) long and is usually dense with tiny spikelets. It reproduces mainly by seed, but it can also spread via rhizome. This bunchgrass occurs in many plant communities in varied climates. It is considered good forage for livestock.

Editorial summary

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

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 110-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 Agrostis, exarata 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 “Agrostis exarata”, 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 Jun 29, 2025. The linked authority identifier is Q4694276. None of the 0 selected statements returned an explicit reference.

Critical limits

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.

How to read it
