Thirty three species of Eriocaulon are recognized in this generic revision for Australia. Eriocaulon carsonii F.Muell, is recognized with 3 subspecies. The identity of E. pallidum R.Br. remains uncertain and this species is treated as 'Incertae Sedis' . A conservative approach to species recognition has been adopted and a number of forms are discussed under E. athertonense G.J.Leach, E. australe R.Br., E. cinereum R.Br., E. depressum R.Br. ex Sm., E. nanum R.Br., E. patericola G.J.Leach and E. pygmaeum Sol. ex Sm. The new species E. fenshamii and E. wolseleyi are described. Lectotypifications are provided for Electrosperma australasicum F.Muell., Eriocaulon ciliiflorum F.Muell., E. concretum F.Muell., E. nanum R.Br., E. nigricans R.Br., E. smithii R.Br., E. spectabile F.Muell. and E. willdenovianum Moldenke. The genus is found in all mainland States and Territories of Australia but is best represented in the tropics and sub-tropics. Species with extra-Australian distributions are E. australe, E. cinereum, E. depressum, E. setaceum L., E. truncatum Buch.-Ham. ex Mart., E. willdenovianum and E. zollingerianum Koernicke. A key to the Australian species, descriptions and distribution maps are provided. Seed coat ornamentation is an important diagnostic and identification character and SEM images are provided for each species.

The genus Leiothrix (Eriocaulaceae) is restricted to South America, where most species occur in the Espinhaço mountain chain in Brazil. Seed ornamentation has a distinctive origin in the family and in most species of Leiothrix the seed coat has a striated pattern. The objective of this study was to evaluate the morphological aspects of seeds of Leiothrix as well as the post‐seminal development. Leiothrix seeds are elliptical or oval, the seed coat has a primary sculpture of isodiametric or hexagonal cells with concave periclinal walls and straight or sinuose anticlinal walls. Most species also have a secondary sculpture, which forms the striate ornamentation and this may be continuous or discontinuous with isolated, connected or cruciform annular striae. A comparative table of seed characters shows that most of them corroborate the current circumscription of the subgenera of Leiothrix. The seed coat striae expand with wetting and may help in seed imbibition during germination. Leiothrix seeds show a high germination rate and the post‐seminal development pattern is similar to that described for other species of Eriocaulaceae.
