  • This scrambling annual or perennial herb is best identified during its main flowering period, January to April, as flood events may cause loss of above ground parts in winter. However, the species’ distinctive leaf sheaths means that it can be identified in the absence of flowers.
  • In Tasmania, Persicaria subsessilis occurs in Launceston and on the Ringarooma River in rocky (dolerite) river margins, where it co-occurs with the more frequent Persicaria hydropiper (green waterpepper); disturbed Melaleuca ericifolia (coast paperbark) swamp forest and lagoon margins; Cyperus lucidus (leafy flatsedge) sedgeland with the allied Persicaria praetermissa (arrow waterpepper) prominent; and within openings in riparian scrub on alluvium.

Permit: A permit is required under the Tasmanian Threatened Species Protection Act 1995 to 'take' (which includes kill, injure, catch, damage, destroy and collect), keep, trade in or process any specimen or products of a listed species. Additional permits may also be required under other Acts or regulations to take, disturb or interfere with any form of wildlife or its products, (e.g. dens, nests, bones). This may also depend on the tenure of the land and other agreements relating to its management. ​​​​​
