Original publication and holotype designation: Montagne, J.F.C. (1842). Algae. In: Histoire physique, politique et naturelle de l'Ile de Cuba. Botanique-plantes cellulaires. (De La Sagra, R. Eds), pp. 1-104. Paris:

Description: Thallus dorsiventral, with prostrate and erect indeterminate axes bearing simple or branched determinate laterals usually at regular intervals; apices occasionally straight, but usually curved to circinate. Attachment by rhizoidal haptera terminal on special branches ('cladohaptera') or clustered on peripheral cells ('peripherohaptera'). Axes with 4–9 pericentral cells, each dividing transversely into 2 tiers, corticate or not. Branching exogenous, rarely endogenous. Trichoblasts absent. Spermatangia superficial on corticated polysiphonous determinate laterals with or without a sterile tip. Procarps 1–4 per segment on polysiphonous determinate branches, each procarp with a single sterile group and a (3–) 4- celled carpogonial branch. Carposporophyte with a short branched gonimoblast bearing clavate terminal carposporangia. Cystocarps subterminal, ovoid to subspherical; pericarp with 6–14 longitudinal filaments, corticated. Tetrasporangia tetrahedrally divided, whorled, borne in stichidia on determinate laterals, up to 25 segments long; fertile segments with 4 or 5 pericentral cells and tetrasporangia, each protected by 2 or 3 cover cells that are often subdivided [after Womersley (2003: 362)].

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
