This is an indicative distribution map of the present distribution of the species based on best available knowledge. See map caveat for more information.
Bertya calycina is a branched shrub, growing to 4 metres high (Halford & Henderson 2002).
This species is confined to the Warrego district of south-western Queensland. It occurs at the south-western extremity of the Chesterton Range north-east of Morven and has a known distributional range of about 12 km (BRI; Halford & Henderson 2002).
In 2002, there was one known population consisting of about 20-30 plants, in a designated State Forest (Halford & Henderson 2002).
Bertya sp. Winneba (D.Jermyn 31) was formally named as Bertya calycina in 2002 (Halford & Henderson 2002).
Bertya calycina seems most closely related to Bertya glandulosa but differs in its white rather than pale rusty coloured hairs, linear leaves with shorter petioles, and its female flowers with concave rather than convex calyx lobes. It also resembles some forms of Bertya pedicellata but is distinguished by its shorter and narrower leaves with shorter petioles, and its densely hairy rather than glabrous or sparsely hairy ovary (Halford & Henderson 2002).
Bertya calycina grows among sandstone outcrops in mallee woodland communities on shallow reddish sandy to sandy loam soils on lower slopes and in gullies around a low sandstone plateau (BRI; Halford & Henderson 2002). Associated with Ironbark/Bloodwood woodland with Acacia spp. intermixed or Eucalyptus bakeri mallee woodland (BRI).
Flowers have been recorded in August, September, October and November, with fruiting in August (BRI; Halford & Henderson 2002). Plants are monoecious (having male and female flowers on the same plant) or dioecious (having male and female flowers on different plants) ( Halford & Henderson 2002).
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.
