Description

Tetratheca juncea has a sprawling habit with stems, usually leafless, between 30 and 60 cm long. Stems usually have 2 to 3 narrow wings which can distinguish the plant from other Tetratheca species. Its four petalled flowers face downward and vary from white to pink to dark purple in colour.[1]

Tetratheca juncea reproduces by spreading underground stems up to 50 cm or sexually, however this requires pollination by insects.[1]

Distribution and habitat

It is found largely in the grassy groundcover of low open forest/woodland with a mixed shrub understorey. This plant prefers cooler southerly aspects and well-drained soils, thus often occurring on ridges.

The vulnerable status of T. juncea reflects its confinement to a small area in the northern part of the Sydney Basin bioregion and the southern part of the North Coast bioregion.[3] Within that area, however, the plant is quite plentiful.[4] Larger populations are considered especially important for the conservation of this species.[1]

gollark: > youll get into contact with the same number of people at the store regardless of whos out doing something elseBut a different number of them will have COVID-19 and might be able to infect you.
gollark: I guess if you could hibernate somehow...
gollark: Sadly, humans just don't have the surface area.
gollark: And you are less likely to be infected there if you have fewer people going out for nonessential reasons.
