Original publication and holotype designation: Weber-van Bosse, A. (1904). Note sur deux algues de l'Archipel Malaisien. Recueil des Travaux Botaniques Néerlandais 1: 96-105, 2 figs.

Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Díaz-Tapia, P., Pasella, M.M., Verbruggen, H. & Maggs, C.A. (2019). Morphological evolution and classification of the red algal order Ceramiales inferred using plastid phylogenomics. Molecular Phylogenetics and Evolution 137: 76-85, fig. 3.

Description: Thallus decumbent, sympodially developed and bilaterally to dorsiventrally organized, alternately producing from every 2 or 3 cells short spine-like or longer indeterminate branches which below the apex are displaced to distichous positions. Indeterminate axes compressed and appearing winged in lower portions due to the overlap of spine-like branches on the margins. Short adventitious branches developing dorsally in the axils of some lateral branches, some of these becoming fertile. Axial cells surrounded by 4 periaxials which are quickly corticated cells by short descending rhizoidal filaments, collectively forming a thick cortex.

Fertile branches upright and radially developed. Procarps produced on short lateral branches of upright axes, consisting of a 4-celled carpogonial branch and 2 sterile groups of cells borne on the supporting cell. Carposporophytes surrounded by extensive pericarps and producing terminal carposporangia. Two tetrahedral sporangia produced in several successive segments on short lateral branches of upright axes forming short, sessile stichidia.

Numbers of names and species: There are 2 species names in the database at present, of which 2 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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.

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.
