A revision is made of the lichen family Thelotremataceae in Dominica, based on previously published records by Elliott and on collections by the author. The family comprises 48 species in 4 genera, Leptotrema, Ocellularia, Phaeotrema, and Thelotrema. The following 15 species are described as new: Ocellularia antillensis, O. conglomerata, O. dominicana, O. maculata, O. mordenii, O. nigropuncta, O. rimosa, O. sorediata, Phaeotrema aggregatum, P. obscurum, Thelotrema confusum, T. dominicanum, T. papillosum, T. tenue, and Leptotrema deceptum. Three new combinations, Ocellularia fecunda (Vainio) Hale, Phaeotrema disciforme (Leighton) Hale, and Leptotrema occultum (Eschweiler) Hale, are also made. Morphological characters are reviewed and the chemistry of each species is presented in detail. The family is exceptionally well developed in mature rain forest.
The genus Boerhavia is discussed, its infrageneric classification is reviewed, and four sub-genera are recognized. Distinctions of two Linnaean species, B. diffusa and B. repens are clarified. Boerhavia mutabilis R. Brown and B. pubescens R. Brown are typified. The Boerhavia repens group is discussed and delimited, as is B. rubicunda and several similar species. Boerhavia repens var. maris-indici, B. albiflora, B. crispifolia, and B. herbstii are described as new. A curious abnormal form of B. crispifolia is also described and discussed.
This book will present information on Pantanal vegetation including an updated checklist of flora, useful plants, ecological aspects and some topics never published for this region, such as lichens. It aims to be a reference for researchers, graduate and undergraduate students as well as stakeholders and decision makers interested in the flora and vegetation of one of the world’s largest tropical wetlands.
