Manuscripts will be submitted continuously in a single document to the email actabotanicacubana@gmail.com. The texts must be sent on Letter size pages, double spaced, Arial font size 11 points, justified paragraphs and without indentation, and 2.0 cm margins. Fonts in italics (italic) should be limited to terms in Latin (scientific names and Latin expressions), or in languages other than the text. Each contribution must be preceded by a title (in Spanish and English), author data, short title, summary/abstract and keywords/key words. Next, the sections that correspond to each type of work will be presented and the headings of these sessions will be written in sustained capital letters, centered and in bold (for example, INTRODUCTION, MATERIALS AND METHODS), if they include sub-headings they will be written in bold in high and low and left-justified with no trailing period. All pages, except the first, will be with page numbering in the lower right corner.
