Prior to the publication of this volume, the Lejeuneaceae subfamily Ptychantoideae of Australia has been very poorly documented in the hepaticological literature, with some of the earliest work on the group being notable for its uncritical nature. This volume documents 30 species of Ptychanthoideae in Australia, 21 of them not previously reported from the continent. Keys are provided to all genera and species, and descriptions and illustrations are given for most taxa.
Barbara Thiers is the Patricia K. Holmgren Director of the William and Lynda Steere Herbarium. She is responsible for overseeing the Garden's 7.3 million collections of algae, bryophytes, fungi and vascular plants and the approximately 30 staff members who manage these collections. The Steere Herbarium is the largest in the Western Hemisphere, and among the four largest in the world. The subject of her research is the Hepaticae. In particular, she is interested in the systematics and morphology of the largest family of Hepaticae, the Lejeuneaceae. This family is primarily tropical in distribution, and its members can be found growing, often profusely, on the bark and sometimes on living leaves of trees in tropical rainforests. Her studies of these small but beautiful plants have taken her to Australia, Colombia, Dominican Republic, Ecuador, French Guiana, Papua New Guinea, Puerto Rico and Venezuela.
