NCBI Nucleotide Sequences
As of 2 June 2009, nucleotide sequence data are available at http://www.ncbi.nlm.nih.gov/Genbank for 10 samples identified as Phyllospadix. Taxonomic identifications of these samples to genus (or species) levels unaccompanied by explicit indication of voucher specimens may not be verifiable on morphological/anatomical grounds and consequently be of little or no taxonomic value, as noted by Harvey et al. 2009.
Numbers of names and species: There are 5 species names in the database at present, of which 5 have been flagged as currently accepted taxonomically.
Names: ('C' indicates a name that is currently accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Contributors
Many of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,
organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America
and intended to be published in CD format.
The descriptions are being continually updated, however, and each current contributor is identified above.
The PSA and AlgaeBase warmly acknowledge the generosity of all past and present
contributors and of Dr Parker.
