From volume 44 on, Darwiniana follows “The Chicago Manual of Style” (2003), 15th edition, Chicago,
University of Chicago Press, for english texts; and X. Fuentes Arderiu, F. Antoja Ribó & M. J. Castiñeiras
Lacambra, “Manual de Estilo para la Redacción de Textos Científicos y Profesionales”,<http://www.ifcc.org/ria/docs/estilo2.pdf>, [Accessed: November 24, 2005], and “Manual de estilo de la
lengua española” (2000) by J. Martínez de Souza, Gijón, Ediciones Trea, for spanish texts.
Manuscripts are structured as follows: 1) title and authors; 2) resumen and abstract; 3) text; 4)
bibliography; 5) tables; 6) illustrations. The main stylistic norms for each part are briefly described below.For
more information, please contact the Editorial Board, or a recent issue of Darwiniana may be used as a model.
Title and authors
- The first page of the manuscript contains the following information: 1) title; 2) authors; 3) authors’ institutional address; 4) P.O. Box or e-mail of the author for correspondence; and 5) runnig title.
- Manuscript’s title is written with capitals without a full stop or period (genera, species and infraspecifics
names italicized). Generic and specific names of vascular plants go with the corresponding family name
(subfamily and tribe names according to each case) between brackets. Those of nonvascular plants go
with the division name between brackets. Avoid the use of authority for scientific names in the title.
- Author names are written with capitals along the same line. Use “&” to connect the last author with the
- Authors’ institutional address is consigned with reference marks only in the case of two or more authors
with different addresses. The e-mail address of the author for correspondence follows the institutional
address after a semicolon.
- The running title must not be longer than one line including author names.
Resumen and abstract
- The second page of the manuscript contains in separated paragraphs: 1) spanish abstract (resumen); 2)
spanish keywords (palabras clave); 3) english abstract; 4) english keywords. Keywords are arranged in
- A one-paragraph abstract and "resumen" (spanish abstract) precede the text. The abstract and "resumen" should be concise and include authors, year, title, brief statements about the paper’s intent, materials and
methods, results and significance of findings.
- Taxon authorities are not included in the abstract.
- No more than 8 keywords are recommended. They usually mark the subject, studied taxa (generic or
higher rank), and geographic area. Scientific names of species are not accepted as keywords.
- The contents of both abstract and “resumen” must be identical. The same requirement applies to the
- The following chapters are recommended: INTRODUCTION, MATERIAL AND METHODS,
RESULTS, DISCUSSION, CONCLUSIONS, ACKNOWLEDGMENTS, BIBLIOGRAPHY. This
scheme can be varied, for instance, in taxonomic papers.
- Up to two levels of subtitles are allowed within every chapter. The subtitle of the first level is aligned on
the left, with no full stop, and the paragraph begins in a new line. The subtitle of the second level is
aligned on the left, with a stop separating the subtitle from text in the same line.
- The chapter “Material and Methods” of non taxonomic papers should have detailed information of the vouchers used as reference material for the studied taxa. (See style in examined material of taxonomic
- Only names of genera, species and infraspecific categories are bolded (as titles) or italicized (in the text);
latin abreviations, such as sp. nov., comb. nov., var., sens. lat., non, ex, or names of subgenera and
sections are not bolded or italicized. Correct accents, umlauts, and other diacritical marks should be
included. Sentences do not begin with abreviations.
- Words or sentences used from their original language, if different from that of the text, are written
between quotation marks following their own spelling rules, for example: “Österreich”, “Geokarpie”, “in
vitro”. (Geographic names do not need quotation marks).
- Arabic numbers are recommended. Numbers at the begining of a sentence should be fully spelled.
- Units of measure and cardinal points have no full stop (period) except in. (inches), for example: cm, g,
ml, µm, or N, S, NE, SW.
- There is one space after each punctuation mark and also between numbers and its unit of meassure. For
instance: A. L. Cabrera but not A.L. Cabrera, 8 mm but not 8mm. Abbreviations of authors of scientific
names do not follow this rule, but the puntuation recommended by Authors of Plant Names (Brummit &
- Acronyms should be capitalized with no full stop, for example: FAA (formol, alcohol, acetic acid).
- Bibliographic references in the text are as follows: (Gamundí, 1960), (Gamundí, 1960: 135), according to
Gamundí (1960), Jones & Smith (1970) or Naranjo et al. (1982) when authors are more than three.
- Every table and figure must be cited in the text with the following style: (Table 2), (Fig. 3C), (Fig. 2C-E,
H), (Figs. ·B and 4C-G).
- Try to avoid footnotes in the text. When necessary, use arabics numbers for footnotes in the text and
small letters for footnotes in tables.
- The acknowledgements are written in only one paragraph, and they should mention people who provided
some kind of academic or technical support or collaboration, as well as the organizations that provided
economical support for the research. Personal names are cited without their academic degree.
Text of taxonomic treatments
- New taxa must be illustrated, particularly their diagnostic characters. A discussion about their
relationships with closest taxa, a key and a map with their geographical distribution are also obligatory
- Taxon authorities should be abbreviated according to Authors of Plant Names (Brummit & Powell, 1992)
with with the initial letter capitalized. They are omitted from both title and captions. They are cited only
once, when scientific names appear in the text for the first time or, if it is not that case, in the material
listed in Material and Methods.
- Books should be abbreviated according to Taxonomic Literature, edition 2, with the initial letter
- Herbaria should be abbreviated according to Holmgren et al., 1990, Index Herbariorum, edition 8.
- Vernacular plant names should be written as proper nouns, between quotation marks and separated by
- Taxon binomial authors formally cited in the text are fully spelled, for example: Linnaeus instead of L.,
Humboldt, Bonpland & Kunth instead of H.B.K.
- Illustrations should be cited for known taxa contained in the treatment, especially when the paper does
not include any figure of these taxa.
- When relevant, nomina nuda, misapplied names and superfluous names are included in the discussion
following the description (under “Observation” subtitle of the corresponding species), but are not part of
the formal synonymy.
- Genera and plant scientific names names are numbered and arranged alphabetically, within every family
and genus. Taxa below the species rank are identified with small letters.
- Taxonomic information of scientific names of species is arranged in one paragraph per name, according
to the following example and punctuation marks:
Panicum hirticaule J. Presl, Reliq. haenk. 1: 308. 1830. P. polygamun Sw. var. hirticaule (J. Presl) E.
Fourn. Mexic. pl. 2: 28.1886. P. capillare L. var. hirticaule (J. Presl) Gould, Madroño 10: 94. 1949.
TYPE: México. Guerrero: Acapulco, Haenke s.n. (holotype PR, not seen; isotypes MO-1837663!, US-
80698 not seen). Fig. 2.
Panicum capillare L. var. miliaceum Vasey, Contr. U.S. Natl. Herb. 1: 28. 1890, hom. illeg. Panicum
sonorum Beal, Grasses N. Amer. 2: 130. 1896. Panicum hirticaule J. Presl var. miliaceum (Vasey)
Beetle, Phytologia 47: 381. 1981. TYPE: México. Sonora: Lerdo, 1889, Palmer 947 (holotype US-
2903025; isotype SI!).
- According to each case, these chapters follow taxonomic treatments: DUBIOUS NAMES AND
EXCLUDED TAXA (before ACKNOWLEDGMENTS); INDEX OF SCIENTIFIC AND POPULAR
NAMES, INDEX OF COLLECTORS (after BIBLIOGRAPHY).
- Keys should be dichotomous, left-aligned without indentations. Each dilemma should finish with a full
stop. Avoid too extensive dilemmas. Keys should be checked carefully for consistency with the
- Specimens are cited in the text in alphabetical order according to the example:
Specimens examined (or Representative specimens examined)

- If many specimens were examined, those cited in the text are limited to one collection by geographical
area (department, province, state, etc). Long lists of specimens examined can be placed following the
Bibliography. They are arranged alphabetically by collector, including collection number followed by the
number of the taxon in text (between brackets).
- Information on reproductive status (fl or fr) is highly recommended.
- The bibliography should be arranged alphabetically by author(s). Two or more papers of the same
author(s) should be arranged chronologically. For instance:
