Bertya ernestiana is a branched shrub growing to 1.5 m high (Halford & Henderson 2002).

This species is known only from Mt Ernest, within Mt Barney National Park, in the Moreton district of south-eastern Queensland (BRI; Halford & Henderson 2002). The population is estimated to number a few hundred plants (D.Halford 2001, pers. comm.).

Bertya sp. Mt Ernest (G.Leiper AQ 507685) was formally named as Bertya ernestiana in 2002 (Halford & Henderson 2002).

It is most closely related to Bertya pedicellata but differs in its smaller stature (1.5 m rather than up to 6 m high), its glabrous rather than stellate-hairy stems, and its calyx lobes being less than, rather than exceeding, half the length of the capsule. Bertya ernestiana also appears never to have more than one flower per inflorescence, whereas Bertya pedicellata sometimes has two (Halford & Henderson 2002).

This species grows on skeletal sandy loam soils derived from rhyolite on steep rocky slopes and rock pavements in heath or open eucalypt forest with heath understorey (BRI; Halford & Henderson 2002).

Flowers and fruits have been recorded in April, July and September (BRI; Halford & Henderson 2002). Plants are monoecious (having male and female flowers on the same plant) (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.
