Much-branched diffuse annual or short-lived perennial, stems to 30 cm long, reddish, papillose all over and often pilose with scattered hairs on older stems, at length woody basally, arising from often a woody tap root; leaves opposite, subsessile (in S.Aust.), oblong-obovate, to 8 x 4.4 mm (2-4.5 x 1-2.5 mm in S.Aust.), obtuse, asymmetrical at the base, entire or minutely serrulate at the summit, green, glaucous (in S.Aust.) and minutely and densely papillose on both sides; stipules filiformly fringed, exceeding the petiole, pink to white.

cyathia on peduncles to 0.5 mm long, red (in S.Aust.), single in upper axils or terminal on very short branchlets, supported by 2 terminal raylet-leaves which exceed the cyathia; involucre turbinate, c. 1 mm long, red, minutely but densely papillose; glands 4, reniform, 0.2-0.5 mm long, red, rarely with crenate appendages of long or short teeth, usually with appendages reduced to a circular rim c. 0.1 mm wide or absent; styles filiform, deeply divided, ascending, red (in S.Aust.).

Taxonomic notes: Shows similarities with E. drummondii and when the papillae (on stems, fruits and seeds) are very fine these 2 species are indistinguishable. The papillae are visible under magnification only and they are more obvious in the NW and NE regions but further south in FR and EA regions they become very fine and unrecognisable, E. inappendiculata is, perhaps only a variant of E. drummondii.
