Hesperostipa spartea, formerly Stipa spartea, is a species of grass known by the common names porcupine grass, western porcupine grass, short-awn porcupine grass, porcupine needlegrass, and big needlegrass. It is native to North America, where it is widespread from British Columbia to Ontario in Canada and through the central and Great Lakes regions of the United States. It is a bunchgrass species in the genus Hesperostipa.
Distribution
Hesperostipa spartea is native to the Great Plains and Canadian Prairies of North America. It is also found in grasslands of the Rocky Mountains in Western Canada and the Western United States.
This grass is common and is a dominant grass in various prairie and grassland ecosystems in the Great Plains. In Alberta it is codominant with rough fescue on the grasslands. In other areas it may be codominant with little bluestem. It may be a pioneer species or a climax species, occurring in all stages of ecological succession. It thrives on poor soils and it can invade disturbed habitat such as gopher mounds.
Begin with the source’s own compact description: “Hesperostipa spartea” is species of plant. The dossier treats that line as a proposition to test through Hesperostipa, spartea 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 Jun 29, 2025. The linked authority identifier is Q3134721. None of the 0 selected statements returned an explicit reference.
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.
