فلور استرالیا: جنس‌های گنتیانیال، جلد ۲۸

Volume 28 describes the order Gentianales, which in Australia comprises four families: Loganiaceae, Gentianaceae, Apocynaceae and Asclepiadaceae. Descriptions are provided for 62 genera and 326 species in these families. Loganiaceae are a mainly tropical and subtropical family. In Australia there are 9 genera and 100 species but the majority of species are found in 2 genera, Logania (33 species) and Mitrasacme (48 species). Two newly described genera, segregated from Mitrasacme, are included in this treatment. The Australian Gentianaceae consist of 8 genera and 31 species. The montane taxa have until recently been included in Gentianella, but here they are distributed between Gentiana and Chionogentias. Apocynaceae are a pantropical family, with 22 genera and 87 species in Australia. The family contains a large number of ornamental species that are extensively cultivated in tropical and subtropical regions. Many species have toxic fruit and foliage, and some species are important as a source of alkaloids in medical research. Asclepiadaceae are also pantropical. They are perhaps best known for their very specialised floral structure, and many, including Hoya, Asclepias and Dischidia, are grown as horticultural subjects. Australia has 23 genera and 98 species. This volume covers 4 families, 62 genera and 326 species. 40 new taxa are described, including 2 new genera in Loganiaceae - Schizacme Dunlop and Phyllangium Dunlop, as well as many new combinations and lectotypifications.
