Chromosome number determinations are reported for 22 species of Australian Restionaceae. The segregation of new species formerly included in Lepyrodia scariosa R.Br. sens. lat. has required the redetermination of voucher specimens and some previously reported counts apply to the newly segregated species. A recent DNA-based phylogeny is a basis for discussing these findings together with previously reported counts. In Restionaceae n = 12 appears plesiomorphic in Leptocarpoideae, while both n = 7 and n = 9 are found in Sporadanthoideae. © 2012 Royal Botanic Gardens and Domain Trust. Source

Ecdeiocolea rigens B.G.Briggs is described and illustrated, being the second species of its genus and third species recognised in Ecdeiocoleaceae. E. rigens is abundant on sand plains in a region north and east of Geraldton in the west of Western Australia. It occurs sympatrically, without evidence of intergradation, with the more widespread E. monostachya F. Muell. and is distinguished by its extensively rhizomatous habit, larger size and rigid culms. Brief comment is made on culm anatomy and DNA findings. A lectotype is selected for E. monostachya. © 2011 Royal Botanic Gardens and Domain Trust. Source
