Source-derived summary

Deschampsia antarctica, the Antarctic hair grass, is one of two vascular flowering plants native to Antarctica, the other being Colobanthus quitensis (Antarctic pearlwort).

It is usually less than a half a foot in diameter.

Habitat and ecology

In Antarctica, the plant can be found forming low clumps in wet, protected habitats.

Deschampsia antarctica mainly occurs on the South Orkney Islands, the South Shetland Islands, and along the western Antarctic Peninsula. Deschampsia antartica distribution largely depends on the area's nutrient supply of the soil and its water distribution. Deschampsia antarctica has been recorded by the Guinness Book of World Records as the southernmost flowering plant. In 1981, a specimen was found on the Antarctic Peninsula's Refuge Islands at a latitude of 68°21′S.

Climate change

Since 2009, both D. antarctica and C. quitensis have been spreading rapidly, which studies suggest has been the result of rising air temperatures and a reduction in the number of fur seals.

Reproduction

The plant is capable of reproducing sexually through self-pollination or outcrossing, and asexually through vegetative spread. Pollination with other plants usually occurs via the wind. Self-pollination usually occurs through cleistogamy, a type of self-pollination that occurs within non-opening flowers.

Editorial summary

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

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—1981, 2009—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Deschampsia, antarctica 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 “Deschampsia antarctica”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q426089. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1981 and 2009.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
