Renziana Vol. 4
Joining previous issues of Renziana covering Paphiopedilum, Phalaenopsis, and Vanda, the current issue focuses on everything Cattleya – morphology, classification as the result of DNA sequence data, distribution, biogeography, ecology, conservation, pollination, breeding, and cultivation. The primary author for this issue is the widely acknowledged expert on Laeliinae and especially Cattleya, Cássio van den Berg. He recounts the taxonomic history of the genus and explains the rationale for lumping Sophronitis and Brazilian Laelia species into Cattleya as series of C. subgenus Cattleya section Crispae. He reminds us that Robert L. Dressler argued for the same reclassification 25 years ago ...

Genera Orchidacearum Volume 3
Genera Orchidacearum is the first monograph of the world's orchid genera that reflects their long evolutionary history and reveals relationships based on genealogical descent and the most up-to-date DNA data.

Phylogenomic Discordance in Plant Systematics
Phylogenetics often uncovers contradicting hypotheses regarding the relationships within the same group of organisms, a phenomenon known since the beginning of the molecular systematics era. While, historically, single marker-based analyses produced discordance, nowadays entire cellular genomes or portions of the same genomic compartment conflict with others or the rest, respectively. In contrast to the beginning of the molecular systematics era, when adding markers and taxa offered a way out of systematic errors, genome inference-based incongruences cannot be addressed and explained easily. Disagreeing phylogenomic hypotheses might originate from various evolutionary processes, including but not limited to hybridization or incomplete lineage sorting, thereby leading to gene tree-versus species tree-associated discrepancies. Today, this can be expanded to genome discordance, where phylogenomic signals of organellar genomes (plastid, mitochondrial) and the nuclear genome disagree due to intrinsically different coalescent paths or phenomena like organelle capture.
The Book of Orchids
One of every seven flowering plants on earth is an orchid. Some are stunningly over the top; others almost inconspicuous. The Orchidaceae is the second most widely geographically distributed family, after the grasses, yet remains one of the least understood. This book will profile 600 species, representing the remarkable and unexpected diversity and complexity in the taxonomy and phylogeny of these beguiling plants, and the extraordinary means they have evolved in order to ensure the attraction of pollinators. Each species entry includes life-size photographs to capture botanical detail, as well as information on distribution, peak flowering period, and unique attributes--both natural and cultural. The result is a work which will attract and allure, much as the orchids themselves do.
Sunflowers, Magnolia Trees & Other Flowering Plants
Discusses a variety of flowering plants and trees, describing their physical characteristics, life cycle, and products made from plants.
