BRIT Press books have been published since 1987 under the series title Sida, Botanical Miscellany (ISSN 0883-1475). They are devoted to a comprehensive study of one topic, ranging from floras to systematic monographs to botanical histories, and provide a greater depth of coverage for larger, key topics. They are published irregularly and have ranged from 40 to 1640 pages. BRIT Press books may be published in English or Spanish, with abstracts in both languages. Maps and line drawings are useful, with color used appropriately.
