“…Cleomaceae, the cosmopolitan sister family to the Brassicaceae, is well-supported by both morphological and molecular data (Hall & al., 2002;Hall, 2008;Iltis & al., 2011). Previous studies have elucidated our broad understanding of the phylogenetic relationships within the family (Hall & al., 2002;Sánchez-Acebo, 2005;Hall, 2008;Inda & al., 2008;Feodorova & al., 2010;Iltis & al., 2011;Riser & al., 2013;Patchell & al., 2014;Barrett & al., 2017). The more comprehensive phylogenetic studies (Feodorova & al., 2010;Patchell & al., 2014;Barrett & al., 2017) demonstrated that the generic boundaries in Cleomaceae are problematic, and a taxonomic revision of generic concepts was necessary.…”

The family Cleomaceae is represented in the Neotropics by nine native lineages, with some of them currently recognized as distinct genera and others in need of clear delimitation. We present here a new phylogenetic hypothesis for the New World Cleomaceae with a more comprehensive sampling, including samples of 62 species with emphasis on Tarenaya and based on nrDNA ITS and cpDNA matK and ndhF. Six clades are supported: (1) a new clade comprising Cleome tenuis and Physostemon humilis; and five other previously identified clades: (2) the Dactylaena clade, including the monophyletic Dactylaena and the paraphyletic Physostemon and Mitostylis; (3) the Andean clade, comprising Andinocleome and Podandrogyne; (4) the Melidiscus clade; (5) the Cleoserrata clade, and (6) the Tarenaya clade; the last three corresponding to genera with the same name. The lineage comprising C. tenuis and P. humilis is strongly supported by morphological and molecular datasets, and a new genus, named Iltisiella, comprising these species is proposed here. Tarenaya is clearly demonstrated to be a monophyletic genus, corroborating previous analyses. We identify four subclades in its topology, and the relationships among the species in each subclade revealed to be moderately to strongly resolved. Furthermore, we conducted a historical biogeographical analysis of the New World Cleomaceae on time-calibrated trees, and our results suggest an Oligocene origin at least 35.02 Mya with a MRCA distributed in Mesoamerica and the Northern Andes. For Tarenaya, our results suggest a Miocene origin at least 17 Mya, with the most recent common ancestor in the Chacoan and Atlantic Forest geographic areas.

“…The recognition of Cleome as a paraphyletic genus (Hall et al 2002;Sanchez-Acebo 2005;Hall 2008;Inda et al 2008;Feodorova et al 2010, Patchell et al 2014 has led to the deconstruction of Cleome s.l., and consequently multiple genera have been segregated and reorganized (Iltis & Cochrane 2007;Roalson et al 2015;Thulin & Roalson 2017;Barrett et al 2017;Roalson & Hall 2017;Soares Neto et al 2017), including Tarenaya (Iltis & Cochrane 2007). This taxonomic reorganization was based on morphology, chromosome number, and phylogenetic relationships, and specific nomenclatural recombinations were made for Flora of North America (Iltis & Cochrane 2007) and Flora Mesoamericana .…”

“…The Tarenaya clade is defined by an easily recognized synapomorphy: a pair of spines at the base of the petioles (stipular spines) and is well supported in all phylogenetic studies of the family (Hall et al 2002;Sanchez-Acebo 2005;Hall 2008;Inda et al 2008;Feodorova et al 2010, Patchell et al 2014Barrett et al 2017). Not all of the presumed species of Tarenaya have been sampled for molecular phylogenetic studies, but based on those sampled to date, and on the stipular spine synapomorphy, Tarenaya comprises 37 species.…”

Tarenaya clade includes 37 species based on phylogenetic relationships and on the stipular spine synapomorphy, however only 10 species thought to belong to the genus have had names established in Tarenaya. Besides the two new species are being described, we present 25 new combinations for the species and refine the typification of 13 species. Ten lectotypes and three neotypes are designated here. One generic synonym is also typified.

PremiseCleomaceae is an important model clade for studies of evolutionary processes including genome evolution, floral form diversification, and photosynthetic pathway evolution. Diversification and divergence patterns in Cleomaceae remain tangled as research has been restricted by its worldwide distribution, limited genetic sampling and species coverage, and a lack of definitive fossil calibration points.MethodsWe used target sequence capture and the Angiosperms353 probe set to perform a phylogenetic study of Cleomaceae. We estimated divergence times and biogeographic analyses to explore the origin and diversification of the family. Seed morphology across extant taxa was documented with multifocal image‐stacking techniques and morphological characters were extracted, analyzed, and compared to fossil records.ResultsWe recovered a well‐supported and resolved phylogenetic tree of Cleomaceae generic relationships that includes 236 (~86%) species. We identified 11 principal clades and confidently placed Cleomella as sister to the rest of the family. Our analyses suggested that Cleomaceae and Brassicaceae diverged ~56 mya, and Cleomaceae began to diversify ~53 mya in the Palearctic and Africa. Multiple transatlantic disjunct distributions were identified. Seeds were imaged from 218 (~80%) species in the family and compared to all known fossil species.ConclusionsOur results represent the most comprehensive phylogenetic study of Cleomaceae to date. We identified transatlantic disjunctions and proposed explanations for these patterns, most likely either long‐distance dispersals or contractions in latitudinal distributions caused by climate change over geological timescales. We found that seed morphology varied considerably but mostly mirrored generic relationships.
