Zamiaceae, a family of the ancient order Cycadales, is distributed throughout the tropical and subtropical regions of both the Old and New Worlds. Here, we present a systematic review of Zamiaceae with emphasis on Zamia species from South America. We aim to (a) establish the current knowledge, (b) identify research gaps, and (c) indicate directions for future studies, discussing ecology and conservation of South America species. The search recovered 508 papers, further classified into 11 research topics: taxonomy and systematics, morphology, biochemistry, genetics, phylogeography, population ecology, reproductive biology, ecological interactions, plant propagation, conservation, and reviews. The number of publications doubled in the 21st century, mostly focusing on genetics (n ¼ 60), taxonomy and systematics (n ¼ 52), morphology (n ¼ 36), ecological interactions (n ¼ 30), and an increasing interest in population ecology (n ¼ 29) and conservation (n ¼ 32). Studies are concentrated in North and Central America (54% of all studies) with just 6% (29) addressing South America species of Zamia. Overall, studies point out the key role of pollinators in promoting gene flow through pollen dispersal among populations of Zamiaceae. Therefore, investigate natural history, ecology, reproductive biology, genetic, and phylogeography, especially for South America species, are needed. Moreover, the implementation of in situ and ex situ collections and germplasm banks linked to botanical gardens are essential for the conservation and reestablishment of local populations of critically endangered Zamia species in South America. Concomitantly, we suggest studies modeling the distribution of Zamia species in future climate change scenarios.

“…Occurring from Florida, U.S.A. south to Bolivia, it is also the most broadly distributed genus in the New World. During the last decade there have been remarkable advances in our understanding of Zamia taxonomy, with 17 new species names or combinations published (Schutzman et al 2008, Taylor et al 2008, Calonje 2009, Lindstrom & Idarraga 2009, Acuña 2010, Calonje et al 2010, Calonje et al 2011, Pérez-Farrera et al 2012, Lindstrom et al 2013, Calonje et al 2018, Stevenson et al 2018 and multiple papers providing additional taxonomic and/or nomenclatural clarifications (Nicolalde-Morejón et al 2008, Lindstrom 2009, Nicolalde-Morejón et al 2009, Calonje et al 2010, Applequist 2012, Calonje et al 2015, Pérez-Farrera et al 2016, Ward 2016. Despite recent advances, Zamia populations occurring within the Amazon basin remain poorly understood, with the taxonomic circumscriptions of most accepted species remaining unclear, and the presence of several populations that potentially represent undescribed species.…”

Zamia brasiliensis Calonje & Segalla, a new subterranean-stemmed species of Zamia (Zamiaceae) from Mato Grosso and Rondônia, Brazil, is described and illustrated. It is compared to two morphologically similar species with adjacent geographic distributions: Z. boliviana from the Cerrado biome, and the Amazonian species Z. ulei. The new species shares unarmed petioles with Z. boliviana but is readily distinguishable by its much broader leaflets. Z. brasiliensis has leaflets somewhat resembling those of juvenile individuals of Z. ulei, but the latter species is easily differentiated by the presence of prickles on its petiole.

Taxonomic data is essential to advance the discovery and description of biodiversity, as well as the study of evolutionary processes. Emerging large-scale datasets and new methods of analysis have provided different approaches to describe biodiversity. Here, we present a review of the taxonomic history in Cycadales including an analysis of historical taxonomic concepts and approaches used for species delimitation. We examine the trends in the publication of new species following taxonomic works in books, journals and horticultural catalogues, monographic projects and floras where species treatments were published. In addition, we review the studies concerning species delimitations using the literature available in scientific journals appearing in the database ISI Web of Knowledge. The approaches used were discussed throughout all research focused on empirical and theoretical considerations in each study. We review the current state of the studies on causal processes that have given rise to the currently recognized diversity. The trend shows that taxonomic work on discovery and description of species has been intensive in the last 40 years culminating in 38.8% of binomials published. As a result, we consider the relevance of the monographs and floras for identification of species for other biological disciplines and the content of these contributions is compared and discussed. A total of six criteria (diagnosability, phenetic, phylogenetic, genotypic cluster, niche specialization and coalescent) were detected from the following three approaches to species delimitation within Cycadales: traditional, integrative taxonomy, and monophyletic. In all cases, the results from these species delimitations not only provided a taxonomic treatment or proposed a new species, but also supposedly clarified the other species involved as a result of the new taxonomic concept of the new species described. Most investigations of species delimitation used the traditional approach or a phenetic criteria. Finally, we discuss evolutionary studies on causal processes involved in cycad diversity. This is considered in the context of species delimitation as hypothesis testing for a successful evaluation of variation in both genetic and morphological understanding.
