摘要：

Gracilaria chilensis Bird, McLachlan et Oliveira from Chile and G. sordida Nelson from New Zealand have been compared with respect to reproductive anatomy, chromosome number, interfertility, and organellar DNA restriction profiles. No differences were found in reproductive anatomy, which in these species is distinguished by deep textorii-type spermatangial conceptacles and prominent tubular nutritive cells directed only to the floor of the cystocarp. The species share a chromosome number of n = 24 and are readily interfertile. Electrophoretic profiles of organellar DNA digested with four different restriction endonucleases were virtually identical between the species except for bands that represented accompanying plasmids. However, previous research has indicated that the four plasmid bands in G. chilensis and the single one in G. sordida have a common origin. On these grounds G. chilensis and G. sordida are deemed to conspecific, with the former name having priority.
