 Comments
       
  Comment: The recognition of Halophila johnsonii as a species remains controversial. Data in a recent paper by Short, Moore, and Peyton (2010) indicate that H. johnsonii Eisman (TSN 502870) is not clearly distinguishable from H. ovalis (R. Br.) Hook. f. (TSN 38959). Other recent papers using molecular techniques have also failed to clearly differentiate the species. Robert Haynes (2013, pers. comm.) who authored the treatment for the group in Flora of North America Vol. 22 (2000), which included the taxon as a distinct species, now concurs that H. johnsonii falls within H. ovalis. but notes that more research is needed to clarify relationships within this species complex, especially in the clade that includes H. ovalis, H. hawaiiana and the populations previously referred to as H. johnsonii
