dc.description	Postmetamorphic rays in Heliaster and Labidiaster originate in four `quadrants' between the five primary rays, and not normally in the madreporic interradius. The rays originate in one of two very definite sequences depending on the species. H. kubiniji and H. multiradiatus share one sequence, whereas H. canopus, H. helianthus and Labidiaster share the other sequence. Pycnopodia, Rathbunaster, Heliaster and Labidiaster add rays at far greater sizes and in a manner that is distinctive from other multiradiate starfish, possibly indicating a new taxonomic unit
