TL;DR: In this article, the authors present an up-to-date checklist of the vascular plants of Texas, which includes crops, persistent perennials, and naturalized plants and encompasses over 1,000 changes to the previous (Hatch, 1990) checklist.
Abstract: Everyone with a professional interest in the flora of Texas will welcome this up-to-date checklist of the vascular plants. This comprehensive list also includes crops, persistent perennials, and naturalized plants and encompasses over 1,000 changes to the previous (Hatch, 1990) checklist. The authors have arranged this checklist phylogenetically by classes following the Cronquist system. Several features make this checklist especially useful. Chief among them is the relative synonymy (name history). An extensive index makes current classification and correct nomenclature readily accessible, while the botanical bibliography is the most extensive ever compiled for Texas. The authors also note which plants have been listed as threatened or endangered by the Texas Organization of Endangered Species, which are designated as Federal Noxious Weeds, and which have been chosen as state tree, flower, fruit, etc. by the Texas Legislature.

TL;DR: MatK genes are fast evolving highly variant regions of plant chloroplast DNA that can serve as potential biomarkers for DNA barcoding and also in generating primers for angiosperms with identification of unique motif regions.
Abstract: The Nymphaeales (waterlilly and relatives) lineage has diverged as the second branch of basal angiosperms and comprises of two families: Cabombaceae and Nymphaceae. The classification of Nymphaeales and phylogeny within the flowering plants are quite intriguing as several systems (Thorne system, Dahlgren system, Cronquist system, Takhtajan system and APG III system (Angiosperm Phylogeny Group III system) have attempted to redefine the Nymphaeales taxonomy. There have been also fossil records consisting especially of seeds, pollen, stems, leaves and flowers as early as the lower Cretaceous. Here we present an in silico study of the order Nymphaeales taking maturaseK (matK) and internal transcribed spacer (ITS2) as biomarkers for phylogeny reconstruction (using character-based methods and Bayesian approach) and identification of motifs for DNA barcoding.

TL;DR: This book aims to give a summation of present day knowledge on the flora of China, and in writing it the authors consulted numerous research papers, many of which were published only in the Chinese language.
Abstract: This is a syllabus of the flora of China, one of the richest warm temperate regions of the world. It contains a brief systematic account, following the Englerian system, of all the major groups of seed plants classified under 49 orders and 223 families. Within each order, a list of families, an account of the diagnostic characters, and a key to the families (if there is more than one) are included. Within each family, a simple description, a short note on the distribution, a synoptic key to the Chinese genera, and plants of special interest are also mentioned. Two appendices comprising a list of orders and families arranged according to the A. Cronquist system and a key to these families are also included. This book aims to give a summation of present day knowledge on the flora of China. In writing it the authors consulted numerous research papers, many of which were published only in the Chinese language.
