TL;DR: A phylogenetic hypothesis is generated for 68 Commelinaceae that partially tests previous morphological, taxonomic classifications and finds Callisia to be polyphyletic, consistent with some previous molecular phylogenetic studies, and Tradescantia, Gibasis, Cyanotis, Commelina, and Murdannia, to be monophyletic.
Abstract: The Commelinaceae are a pantropical family of monocotyledonous herbs. Previous phylogenies in Commelinaceae have emphasized sampling among genera. We extended this previous work by sampling multiple species within some of the largest genera of Commelinaceae (especially Commelina and Tradescantia , and also including Callisia , Cyanotis, Gibasis, and Murdannia ), and by sequencing non- coding regions both of the nuclear ribosomal DNA region, 5S NTS, and the chloroplast region, trnL-trnF . We generated a phylogenetic hypoth- esis for 68 Commelinaceae that partially tests previous morphological, taxonomic classifications. We found little evidence for conflict between nuclear and chloroplast regions for Tradescantia , Murdannia , and Callisia , and some evidence for conflict between the two regions for Commelina , though conflicting regions of the phylogeny were only weakly supported by bootstrap analyses. We found subtribe Tradescantieae to be para- phyletic, consistent with an rbcL study, though with a different topology than that produced by rbcL . In addition, subtribe Commelineae was monophyletic with strong support. We found Callisia to be polyphyletic, consistent with some previous molecular phylogenetic studies, and we found Tradescantia , Gibasis , Cyanotis , Commelina , and Murdannia , to be monophyletic. The molecular phylogenies presented here generally supported previous taxonomic classifications. Keywords—Callisia , Commelina , cpDNA , Murdannia , nrDNA , Tradescantia .

TL;DR: The flowers of Tradescantia virginiana, TradesCantia ohioensis, and Callisia navicularis are polysymmetric and comprised of three sepals, three petals, six stamens in two whorls of three, and three connate carpels.
Abstract: The flowers of Tradescantia virginiana, Tradescantia ohioensis, and Callisia navicularis are polysymmetric and comprised of three sepals, three petals, six stamens in two whorls of three, and three connate carpels. Tradescantia and Callisia, as represented in this study, could be distinguished by the relative sizes and shapes of their floral apices. The apex of C. navicularis, for the duration of organ initiation, was considerably smaller and more convex than in either species of Tradescantia. In all three species, the sepals arise, in succession, first. The petals arise next in rapid succession in both Tradescantia species and in very rapid succession or more or less simultaneously in C. navicularis. The carpels arise last in very rapid succession and their connation is evident soon after their initiation. The inner (antepetalous) stamens appear simultaneously with the petals in C. navicularis, and, as with the petals, it is not always clear that these stamens arise sequentially rather than simultaneousl...

TL;DR: The ethanolic extract of Callisia fragrans aerial parts showed a significant strong in vivo anti-inflammatory and in vitro antioxidant activities with a high in vivo gastrointestinal safety profile and a very low in vitro cytotoxicity on peripheral blood mononuclear cells (PBMCs) with an IC50 > 1000 μg/ml.
