Stems bluegreen, glaucous but above more greenish, soft below the inflorescence but fairly hard in the middle, 2,5mm wide. Sheats abaxial goldenbrown. Striations about 48, a bit distinct. Stomata superficial. Pith interrupted with large holes. Inflorescence diffuse but flowers a bit clustered with only erect flowering branches. Tepals with broad hyaline margins. Capsules longer than the tepals.

Stems bluegreen, ±soft, 3,5mm wide. Striations about 65, a bit distinct. Stomata superficial. Pith interrupted with large holes. Inflorescence diffuse with only erect flowering branches! Tepals with broad hyaline margins. Capsules longer than the tepals.

It may be this species. But I dare not exclude Juncus aridicole, which has been found here more. @karenwilsonau Can you take a look at this plant and say whether Juncus aridicola can be ruled out? We found more species from Australia and New Zealand, so this one would be a new one for the list.

Stems bright green, not glaucous, shining, soft, >2mm diam. Pith with large lacunae more septa-like. Stomates superficial. Striations thin, about 51. Capsules a bit wider than Juncus edgariae. Herbarium material collected for Naturalis. @karenwilsonau can you confirm this one?

Juncus 60cm tall with green and hard stems (difficult to compress), not glaucous, about 2,5mm diam. or a bit more. Striations conspicuous, not crowded, about 45 or a bit more than 50. Stomates superficial. Pith interrupted with small lacunae. Upper cataphylls short max. 10cm and loose, yellow brown distally, darkbrown to base. Inflorescence condensed, normally with one head. Lower bract not dilated beneath the inflorescence. All tepals with broad membrenous margins. Stamens 3. Capsules triseptate, equalling perianth. Herbarium material collected for Naturalis.

Different from two species that occur here as well. From Juncus edgariae, which has normally thinner stems, multi-headed inflorescence and narrower trilocular capsules. Different from Juncus procerus, which is more robust with longer cataphylls and thicker and softer stems with more crowded striations and larger lacunae.

On the last few pics. left Juncus astreptus and right Juncus edgariae in compare.

It has been confirmed that a lot of wool has also been imported from Tasmania in the past in the Vesder valley.

Culms green, more than 3mm wide. Pith interrupted with large laccunae. Striations crowded with deeply sunken stomata . Cataphylls yellow distally. Inflorenscence diffuus. Photo under the binoc shows the sunken stomata. Plant from the wool processing industry.

Stems grey-green, soft, 4-5mm wide. Ribs crowded, quite noticeable. Pith interrupted. Inflorescence diffuse, flexuous. Capsules longer than petals.

Juncus aridicola.

Galls were found on plants of Olearia axillaris. The wasp shown in one photo is a parasitic wasp and not the gall midge.
See https://www.biodiversitylibrary.org/page/41319561#page/71/mode/1up for description of the species.

See the following observations for details of the parasitic wasps that emerged from these galls:

In a boggy creek line at c. 730m elevation, not common. Matches photos I have of Carex disticha which have been confirmed with a specimen by Sydney RBG herbarium. Looks a bit like C. appressa but culms are spread along a rhizome, not clumped and inflorescence is shorter.
