Taxonomic status: currently recognized as a distinct genus.

Gender: This genus name is currently treated as feminine.

Most recent taxonomic treatment adopted: Schneider, C.W. & Wynne, M.J. (2007). A synoptic review of the classification of red algal genera a half a century after Kylin's "Die Gattungen der Rhodophyceen". Botanica Marina 50: 197-249.

Description: Uniaxial, terete or distinctly flattened, unbranched or distichously, subdichotomously or proliferously branched to about four orders. Midrib and lateral veins sometimes evident. Margins of ultimate order of branches sometimes fimbriate. Rhizoids surrounding axial cell and four medially situated periaxial cells. Cortical cells subspherical to elliptical, progressively smaller toward cuticle. Secondary pit connections lacking. Pit plugs lacking cap layers.

Monoecious or dioecious. Carpogonium terminating a long, usually unbranched, distally recurved, adventitious filament with slightly enlarged distal cells. Connecting filaments issuing from fusion process, contacting a succession of differentiated auxiliary cells occurring near distal ends of separate, unbranched, percurrent, adventitious filaments. No gonimoblast fusion cell. Most cells of cystocarp maturing into relatively small carposporangia. Carpostome lacking. Spermatangia superficial, cut off by oblique walls. Tetrasporophyte heteromorphic, crustose, Haematocelis- or Cruoriopsis-like. Tetrasporangia small, irregularly cruciate to irregularly zonate, attached basally.

Comments: Farlowia spp. have been shown to have antiviral activity (Ehresmann et al., 1977; Hatch et al., 1979).

Restricted to the North Pacific: northern Japan; Kurile Islands; Prince William Sound, Alaska, to Baja California, Mexico.

Numbers of names and species: There are 5 species names in the database at present, of which 3 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

Names: ('C' indicates a name that is 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
Some 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 (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
