Scientific name: Baloskion longipes

Common name: Dense Cord-rush

Conventionally accepted as Baloskion longipes (CHAH 2010).

The Dense Cord-rush is an erect perennial sedge with culms (flowering stems) growing up to 150 cm long arising from a compact rhizome (underground stem) (Meney & Pate 1999). Culms are narrow, 2–2.5 mm in diameter, and circular in cross section with 6–25 flowering spikelets produced on slender stalks (pedicels) up to 60 mm long towards the top of the culm, but not overly crowded. The flowering glumes (modified leaves or bracts) surrounding each flowering spikelet stalk are pointed, 4–6 mm long and closely pressed towards the apex (top) (Meney & Pate 1999; NSW OEH 2012b; Plantnet 2012).

Male and female flowers are borne on separate plants (dioecious) with male spikelets ovate (egg shaped), 4–8 mm long and with six tepals (modified flower petal) whilst female spikelets are ovate to elliptic in shape, 8.5–9.3 mm long with four tepals (Meney & Pate 1999; NSW OEH 2012b; Plantnet 2012).

The Dense Cord-rush is endemic to NSW where it is known from the Blue Mountains National Park (NP) 81 km west of Sydney; Kanangra-Boyd NP 100 km west of Sydney; in Hanging Rock Swamp at Penrose State Forest approximately 9 km west of Bundanoon; at The Vines in Morton NP west of Nowra; at the summit of The Pass, on the Braidwood-Nelligen Road; and the Clyde Mountain and Ballalaba areas south of Braidwood (NSW OEH 2012b).

No quantative data on population size is known, however, all populations of the species are recorded as 'small' (NSW OEH 2012b).

The Dense Cord-rush is known from Blue Mountains NP, Kanangra-Boyd NP, Morton NP and Penrose State Forest (NSW OEH 2012b).

The Dense Cord-rush grows in seasonally inundated peat, sandy wetland swamps (Meney & Pate 1999) or depressions in sandy alluvium (Harden 1993), sometimes growing with Sphagnum Moss (Sphagnum spp.) (NSW OEH 2012b). It also occurs in swales within tall forest and in Black Gum (Eucalyptus aggregata) woodland (NSW OEH 2012b).

The distribution of this species overlaps with the Temperate Highland Peat Swamps on Sandstone EPBC Act-listed endangered ecological community (DSEWPaC 2012u)

Little is known of the biology of the Dense Cord-rush other than it flowers in summer with seed maturation occurring 6–8 months later (Meney & Pate 1999). The species can resprout after fire (Meney & Pate 1999) and new shoots are produced from underground stems (rhizomes) (NSW OEH 2012b).

The main identified threats to the Dense Cord-rush include (ANRA 2009; NSW OEH 2012b):

  • road works and weed spraying, particularly for the Clyde Mountain and Ballalaba populations due to their close proximity to roads
  • the Pig (Sus scrofa) rooting for food, directly damaging the species and surrounding habitat.

Potential threats to the species are grazing pressure; fragmentation and loss of habitat; and alteration to hydrology and run-off into the swamp habitat (ANRA 2009; NSW OEH 2012b).

The NSW Office of the Environment and Heritage (2012b) identify the following priority actions to assist in protection of the Dense Cord-rush:

  • Inform local and state government and the Rural Fire Service staff about populations adjoining roads and tracks to ensure that plants are considered when roadworks and fire suppression activities are planned.
  • Mark sites and potential habitat onto maps used for planning road work.
  • Ensure runoff from sites above population is controlled.
  • Erect signs to alert management staff to the presence of populations.

Management documents relevant to Baloskion longipes are at the start of the profile. Other relevant documents include the Kanangra-Boyd National Park Plan of Management (NSW NPWS 2001u), Morton National Park Plan of Management (NSW NPWS 2001a), Blue Mountains National Park Plan of Management (NSW NPWS 2001v) and Blue Mountains National Park draft Pest Management Strategy (NSW NPWS 2007c).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
