An annotated plant checklist of the transboundary volcanic Mt Elgon, East Africa.

Mt Elgon is an ancient transboundary volcanic mountain found at the Kenya-Uganda boarder possessing high plant diversity. This study documents an updated checklist of the mountain's vascular plants obtained through random-walk field excursions and retrieval of herbarium specimen tracing back to 1900. We compiled 1709 species from 673 genera in 131 families.

The Lichen Genus (Lobariaceae, Peltigerales) in East African Montane Ecosystems.

The lichen flora of Africa is still poorly known. In many parts of the tropics, recent studies utilizing DNA methods have revealed extraordinary diversity among various groups of lichenized fungi, including the genus . In this study, East African species and their ecology are reviewed using the genetic barcoding marker nuITS and morphological characters.

A New Cryptic Lineage in Parmeliaceae (Ascomycota) with Pharmacological Properties.

We used molecular data to address species delimitation in a species complex of the parmelioid genus and compare the pharmacological properties of the two clades identified. We used HPLC_DAD_MS chromatography to identify and quantify the secondary substances and used a concatenated data set of three ribosomal markers to infer phylogenetic relationships. Some historical herbarium specimens were also examined.

Complete Chloroplast Genomes of (China) and (Africa) (Velloziaceae): Comparative Genomics and Phylogenomic Placement.

P.C. Kao is a Chinese endemic monotypic genus, whereas .

Diversity of (Collemataceae, Ascomycota) in East African Montane Ecosystems.

Tropical mountains and especially their forests are hot spots of biodiversity threatened by human population pressure and climate change. The diversity of lichens in tropical Africa is especially poorly known. Here we use the mtSSU and nuITS molecular markers together with morphology and ecology to assess (Peltigerales, Ascomycota) diversity in the tropical mountains of Taita Hills and Mt.

Initial Complete Chloroplast Genomes of (Rosaceae): Comparative Analysis and Phylogenetic Relationships.

The genus L., known for its medicinal and ornamental value, is widely distributed in the Holarctic regions with a few species found in Asia and Africa. Delimitation of species within is difficult due to hybridization, autonomous apomixes, and polyploidy, necessitating efficient molecular-based characterization.

An annotated checklist of the vascular plants of Aberdare Ranges Forest, a part of Eastern Afromontane Biodiversity Hotspot.

The Aberdare Ranges Forest, located in the Central highlands of Kenya, is an isolated volcanic mountain in the East African Rift Valley with unique flora. Despite its refugial importance to rare and endemic plant species, the diversity of plants in the Aberdare Ranges Forest remains poorly understood. The checklist presented here is a collation of data obtained from multiple floristic surveys and from herbarium specimen collections from the forest.

Circumscription of the genus Lepra, a recently resurrected genus to accommodate the "Variolaria"-group of Pertusaria sensu lato (Pertusariales, Ascomycota).

Pertusarialean lichens include more than 300 species belonging to several independent phylogenetic lineages. Only some of these phylogenetic clades have been comprehensively sampled for molecular data, and formally described as genera. Here we present a taxonomic treatment of a group of pertusarialean lichens formerly known as "Pertusaria amara-group", "Monomurata-group", or "Variolaria-group", which includes widespread and well-known taxa such as P.

Evolution of complex symbiotic relationships in a morphologically derived family of lichen-forming fungi.

We studied the evolutionary history of the Parmeliaceae (Lecanoromycetes, Ascomycota), one of the largest families of lichen-forming fungi with complex and variable morphologies, also including several lichenicolous fungi. We assembled a six-locus data set including nuclear, mitochondrial and low-copy protein-coding genes from 293 operational taxonomic units (OTUs). The lichenicolous lifestyle originated independently three times in lichenized ancestors within Parmeliaceae, and a new generic name is introduced for one of these fungi.
