Carex firma
species of plant
Carex firma is a species of sedge that grows in the mountains of southern and central Europe.
Description
Carex firma forms thick cushions. Its leaves are up to 8 centimetres (3.1 in) long in normal conditions (up to 10 cm or 4 in in moist, sheltered localities), dark green and stiff. The stems are up to 20 cm (7.9 in) tall (exceptionally 30 cm or 12 in), but always at least twice as long as the leaves.
Ecology
In synecology, Carex firma is a characteristic part of the "Caricetum firmae" (also called "Firmetum"), which is an important community in the alpine zone over calcareous rock.
Carex firma can survive temperatures as low as −50 °C (−58 °F).
Taxonomy
Carex firma was first described by Nicolaus Thomas Host in 1797, in his work Synopsis Plantarum in Austria provinciisque adjacentibus sponte crescentium.
The public source identifies “Carex firma” as species of plant. This brief keeps that definition visible, then builds a research path around Carex, firma and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Carex firma”, 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 14, 2025. The linked authority identifier is Q1443970. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1797.
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.
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.
