PREMISE OF THE STUDY Palaeotropic Derris-like taxa (family Fabaceae, tribe Millettieae) comprise 6-9 genera. They are well known as important sources of rotenone toxin, which are used as organic insecticide and fish poison. However, their phylogenetic relationships and classification are still problematic due to insufficient sampling and high morphological variability. METHODS Fifty species o...
Thismia Griffith (1844: 221) usually grows among leaf litter in shady wet forests and comprises 47 small mycoheterotrophic species (Chiang & Hsieh 2011, Mancinelli et al. 2012). Individual plants live underground through most of the year, only emerging briefly to flower and fruit after periods of heavy rain (Ho et al. 2009). Although several species have been described in temperate regions, Thi...
Haemosporidian parasites are widely distributed and common parasites of birds, and the application of molecular techniques has revealed remarkable diversity among their lineages. Four haemosporidian genera infect avian hosts (Plasmodium, Haemoproteus, Leucocytozoon and Fallisia), and Haemoproteus is split into two sub-genera based on morphological evidence and phylogenetic support for two diver...
The leaf-mining moth genus Philodoria Walsingham (Lepidoptera: Gracillariidae) is composed of 30 described species, all of which are endemic to the Hawaiian Islands. Philodoria is known to feed on 10 families of endemic Hawaiian host plants, with several species recorded only from threatened or endangered hosts. Beyond their dependence on these plants, little is known of their evolutionary hist...
Summary Werneria Kunth (Compositae: Senecioneae: Senecioninae) was effectively lectotypified by Rockhausen based on rigida . Two later lectotypifications have apparently been made, firstly (presumably Cabrera) W. graminifolia and secondly Funk) nubigena , yet the Index Nominum Genericorum website has no type stated. In removing to then newly recognised Xenophylllum Funk moved Rockhausen’s there...
