Braun-Blanquet, J. (1932). Plant Sociology: The Study of Plant Communities. Translated, revised, and edited by G. D. Fuller and H. S. Conard. McGraw-Hill, New York. — The foundational statement of the phytosociological method, and the route by which the two-way table entered the English-language literature.

Vegetatio 23: 255–277. https://doi.org/10.1007/BF02326664 — The method coenosr reconstructs, one of the earliest programs to automate Braun-Blanquet tablework. COENOS (1991) was the same authors’ DOS realization of this method.

Mueller-Dombois, D. & Ellenberg, H. (1974). Aims and Methods of Vegetation Ecology. John Wiley & Sons, New York. — The standard reference for the Braun-Blanquet method in English. Its account of the Ceska & Roemer algorithm — “a successive alternation of rules I and II” producing “a fairly close approximation of the hand-derived original” — fixed the description coenosr was built to. The bundled ELLEN example is Ellenberg’s own Arrhenatheretum relevé data.

Bruelheide, H. & Flintrop, T. (1994). Arranging phytosociological tables by species–relevé groups. Journal of Vegetation Science 5: 311–316. — The published density-block search at the heart of form_groups(), explicitly in the Ceska & Roemer lineage, and the source that distinguishes the “outside criterion” COENOS adds.
