TL;DR: A survey of flavonoids in the leaves of 81 species of the Zingiberales showed that, while most of the major classes of Flavonoid are represented in the order, only two families, the Zediberaceae and Marantaceae are rich in these constituents.

TL;DR: Based on phylogeny it is concluded that Africa, in spite of being much poorer in species, is the most likely ancestral area of Marantaceae.

TL;DR: It is suggested, that each group has its closest affinities with Old World genera and that this indicates that the diversification of the marantaceous stock was far–reaching already before the Old and the New World became effectively isolated.
Abstract: The delimitation of the neotropical genera of the Marantaceae has been revised, using evidence mainly from the morphology of inflorescences and flowers. It is concluded that the generic concepts of Schumann in “Das Pflanzenreich”, often questioned by 20th century American authors, are essentially sound, but that his grouping of the genera into two tribes is quite artificial. Main deviations from the treatment of Schumann are the rearrangement of the genera, somewhat different stress on diagnostic characters and a much narrower concept of the genus Myrosma. A new genus, Koernickanthe is proposed for the long known species Maranta orbiculata (Koern.) Schum. The genera are arranged into informal groups and the groups and genera recognized are: Maranta group (Maranta L., Monophyllanthe Schum.), Myrosma group (Myrosma L. f., Saranthe (Regel et Koern.) Eichl., Hylaeanthe Jonker et Jonker, Ctenanthe Eichl., Stromanthe Sond.), Calathea group (Calathea G. F. W. Meyer, lschnosiphon Koern., Pleiostachya Schum.), Monotagma group (Monotagma Schum., Koernickanthe gen. nov.) and Thalia“group”(Thalia L.). It is suggested, that each group has its closest affinities with Old World genera and that this indicates that the diversification of the marantaceous stock was far–reaching already before the Old and the New World became effectively isolated. It is further suggested that the early diversification of the family took place in Africa, the flora of which, although poor in species, is morphologically very diverse. Two new combinations are made, viz. Stromanthe stromanthoides (Macbr.) Anderss. and Koernickanthe orbiculata (Koern.) Anderss.

TL;DR: The results of the chemical composition analysis show that sagu rhizome have more total carbohydrate content and less crude proteins, fat, and fiber than zulu rhizomes.
Abstract: In this study a comparison between the chemical composition and physical characteristics of sagu (Canna edulis Kerr) and zulu (Maranta sp.) rhizomes was made. The rheological properties and morphometric characteristics of starches isolated from both modified underground stems were also compared. Sagu rhizomes are bigger than those of zulu. Their external appearance resembles that of yam. The zulu rhizomes yield larger quantities of edible pulps because of the lower percent of peel. The results of the chemical composition analysis show that sagu rhizomes have more total carbohydrate content and less crude proteins, fat, and fiber than zulu rhizomes. Keywords: Sagu rhizomes; zulu rhizomes; Canna rhizomes; Maranta rhizomes; starch; SEM observation

TL;DR: Calathea is recircumscribed in a narrow sense and Sanblasia is placed in synonymy and the genus Goeppertia is resurrected and redefined to include all members of the second Calathea clade.
Abstract: Calathea, with an estimated 285 species, is the largest genus of Marantaceae and an important component of Neotropical herbaceous diversity. The genus is also of high importance for horticulture as species are cultivated for their showy, patterned leaves. Previous molecular phylogenetic studies indicated that the genus is polyphyletic, but have not provided a basis for redefining generic limits due to incomplete taxon sampling. To address this problem we analyzed DNA sequence data from three plastid markers (matK with flanking 30 trnK intron, trnL intron and trnL-trnF intergenic spacer) and one nuclear marker (ITS) under a maximum parsimony criterion for a large and representative taxon sample covering all previously proposed infrageneric entities, and representing the full range of morphological variation known in the genus. Our results confirm that Calathea is polyphyletic. One clade, including subgenus Calathea ,t heC. lanicaulis group, and the genus Sanblasia, is sister to a clade formed by Ischnosiphon and Pleiostachya .T he genusMonotagma is placed as sister to this clade. The remaining species form a second strongly supported clade as sister to a clade containing these other genera. Based on these findings Calathea is recircumscribed in a narrow sense and Sanblasia is placed in synonymy. The genus Goeppertia is resurrected and redefined to include all members of the second Calathea clade. Morphological characters defining each genus are provided. A total of 246 new combinations are made. Keywords—Goeppertia, ITS, matK, maximum parsimony, Sanblasia, trnL-F region. Marantaceae, with approximately 550 species, is the sec- ond largest family in the Zingiberales. The family is particu- larly diverse in the Neotropics where it is represented by an estimated 450 species. Phylogenetic studies at the family level (Andersson and Chase 2001; Prince and Kress 2006a) have shown Neotropical diversity to primarily involve two large groups: the Maranta clade with nine genera and ca. 70 species is concentrated in southeastern Brazil; and the Calathea clade with five genera and ca. 370 species is distrib- uted throughout the Neotropics but with highest diversity in northwestern South America. Within the Calathea clade, Calathea G. Mey. is by far the largest genus with an esti- mated 300 species (Andersson 1998). Govaerts and Kennedy (2012) list 285 accepted names. These numbers clearly make Calathea the largest genus in the family. The genus is also important for horticulture as indoor plants and in tropical garden landscaping due to their variegated leaves with spots or bands of white, orange, or red, and often bright purple underside. Several species have been used as model organisms for studies of reproductive ecology, plant phys- iology, and demography (e.g. Kennedy 1978; Horvitz and Schemske 2002; Clasen-Bockhoff and Heller 2008; Matlaga and Sternberg, 2009; Swenson 2009; Maron et al. 2010).
