TL;DR: It is found that although useful for improving phylogenetic resolution in the family and providing some species-level insights, plastome sequences only partially improve species discrimination, and this reinforces the need for large-scale nuclear data to improve discrimination among closely related species.

TL;DR: The authors' analysis shows Microlicia s.s. to be paraphyletic with Chaetostoma, Lavoisiera, Stenodon and Trembleya nested in it, and proposes the inclusion of these four genera in a broadly circumscribed Microlicieae, and provides new combinations and names for their species.

TL;DR: This study uses cultivated asparagus as a model to illustrate the concept of identifying crop wild phylorelatives (CWPs) (i.e. CWRs that can breed with the crop) by integrating previous cross-compatibility knowledge and CWR classifications into a phylogenetic framework reconstructed using available sequence data.

TL;DR: It is found that Paepalanthus and 16 of its 28 infrageneric categories are not monophyletic, as well as the closely related genus Actinocephalus, and several new relationships in Eriocaulaceae are revealed.

TL;DR: A species complex in Epidendrum, a mega-diverse Neotropical orchid genus, that is formed by the 11 Brazilian species of the E. difforme group is analysed, indicating that it will be necessary to reassess many of the species complexes in the genus using a similar multidisciplinary perspective to evaluate the number of taxa that should be recognized.

TL;DR: Analysis of plastome and nuclear genomes with comprehensive sampling of Themeda and Heteropogon demonstrate that neither genus is monophyletic as currently circumscribed and establish a foundation for studying the history of these ecologically significant widespread grasses and the ecosystems they form.

TL;DR: Nine newly sequenced plastomes for nine Liliaceae genera have been combined with previously published plastome data for this family, providing a total of 86 complete plastid genome sequences covering all 15 currently recognized genera for analyses.

TL;DR: The first phylogenetic hypothesis for Abildgaardieae is provided using targeted sequencing data obtained with the Angiosperms353 enrichment panel for 50 species and the genus Ab Bildgaardia is recognized, supported by morphological data.

TL;DR: Phyllocladus with fully developed phylloclades have been in place since at least the early Cenozoic and represent one of the adaptations for increasing functional photosynthetic area that are present in Podocarpaceae.

TL;DR: It is concluded that L. simplex is native to both Madagascar and South Africa, probably with a single colonization event from Africa to Madagascar followed by pre-human diversification of L.simplex populations in Madagascar.

TL;DR: This work inferred a nearly complete phylogenetic reconstruction of Croton section Cleodora based on DNA sequences of nuclear ITS and five plastid regions, and estimated divergence times and reconstructed ancestral ranges using Bayesian methods.

TL;DR: A comprehensive study of reproductive organs of three Thismia spp.

TL;DR: The maintenance of Brachyotum as a genus segregated from the recently reinstated Chaetogastra is proposed, indicating that subclades have a strong relationship with geographical distribution.

TL;DR: The results suggest that whole genome duplications are one of the key mechanisms, alone or together with hybridization, governing the diversification of L. suffruticosum s.l. and geographical overlap and high cytogenetic diversity suggest multiple origins of the polyploids.

TL;DR: Using a morphological cladistic approach based on 51 morphological and anatomical characters, it is confirmed the position of Leptagrostis schimperiana and showed that Piptophyllum welwitschii is also a member of Crinipedeae.

TL;DR: The suggested revised delimitation of the Rhabdoweisiaceae family comprises Camptodontium, three subaquatic species currently classified in Blindia (Seligeriaceae), and Glyphomitrium and Eucamptodon perichaetialis (the type species of the genus, previously referred to Dicnemonaceae).

TL;DR: A list of taxonomically important fruit anatomical characters is compiled, which includes 15 characters and 79 character states that can characterize genera or groups of closely related genera.

TL;DR: This work reconstructed a robust phylogenetic backbone of Rhodiola using 23 plastomes representing all subgenera and sections in previous taxonomic treatments and inferred the spatio-temporal pattern of diversification of the genus, demonstrating that plastome data could significantly improve phylogenetic resolution in plant groups resulting from recent radiations.

TL;DR: The results show five clades in Microgramma that do not corroborate any previously proposed infrageneric classification system, and several morphological traits appear to be homoplastic, including leaf dimorphism.

TL;DR: The diversity and development of archegonia, the female reproductive organs of land-plant gametophytes, are reviewed, suggesting that the fully exposed condition is derived and synapomorphic for setaphytes (mosses and liverworts), and developmental genetic bases of archegonium diversity in land plants remain to be understood.

TL;DR: It is found that stamen morphology and plant identity explain variation in their natural frequency, and pollen release induced by vibrating stamens at their natural frequencies might only play a role in a subset of buzz pollination interactions.

TL;DR: Subtle shifts in proportional growth lead to a high diversification of ovaries in core Caryophyllales and the establishment of predictable developmental trends, which clearly represent apomorphic tendencies.

TL;DR: It is demonstrated that diversification rates are similar in morphologically homogeneous and diverse clades and in herbaceous and woody lineages and that wood anatomy in Herbaceous andWoody species does not differ considerably regardless of their continental or insular origin, but it is affected by stem architecture and plant reproductive strategy.

TL;DR: KNOX gene families remained small (maximally five genes) in the representatives of bryophytes, lycopods and ferns examined thus far; however, they expanded to some extent in gymnosperms and, independently and much more strongly, in angiosperms.

TL;DR: The results suggest that reciprocity affects the function of distyly; however, floral traits such as stigmatic lobe length and the pollination environment can also influence the rates of legitimate pollen.

TL;DR: The results of this study showed that populations growing on limestone in the Albanian Alps in northern Albania and southern Montenegro are divergent and should be recognized as a new species, Ranunculus bertisceus Kuzmanović, D.Lakušić, Frajman & Schönsw.
