The current taxonomic concepts based on morphology are confusing and are sometimes based on misidentification or lack of information about the type material. We describe the morphological diversity and infer relationships using molecular phylogenetics. The five petals in all Halgania species are blue to violet (rarely white). The yellow or yellow-purple anthers are connected into a cone surrounding the single style. Differences among the species are mainly found in the indumentum of the plants, the leaf margin (i.e. degree of serration), the sepals (being either of equal or of unequal size) and the length of the beak-like anther appendages. A phylogenetic tree mainly based on ITS sequences retrieves three highly supported groups. The H. andromedifolia clade uniquely has sepals of unequal size, and the H. anagalloides clade exhibits dolabriform trichomes. The remaining taxa (constituting the H. littoralis clade) lack such diagnostic morphological traits, but are reliably retrieved as sister group to the H. anagalloides clade. As a first step towards the taxonomic revision of Halgania, we have compiled a nomenclatural list of all validly published names (at the species level and below), provide information about herbarium deposition of original material and discuss the current use of the names.1 aHolstein, Norbert1 aGottschling, Marc  uhttp://www.publish.csiro.au/paper/SB1701702196nas a2200181   4500008004100000022001400041245012500055210006900180300000900249490000800258520156100266653002201827653002401849653002601873100002201899700002201921856007101943       2018                        eng d  a0367-253000aFlowers of Halgania (Ehretiaceae, Boraginales) are set up for being buzzed and the role of intertwining anther trichomes0 aFlowers of Halgania Ehretiaceae Boraginales are set up for being  a7-150 v2403 aFlowers that release their powdery pollen by being vibrated through buzzing are morphologically diverse and have evolved many times independently. Most prominently, buzz-pollination is known from Solanum (Solanaceae) defining the “solanoid” flower type by Knut Fægri. The flowers of buzz-pollinated, Australian Halgania resemble the actinomorphic Solanum floral architecture: The plants have a yellow anther cone with an apical pore, protruding from a widely funnel-shaped to rotate, blue to violet corolla. However, Fægri rejected the solanoid flower type for some of the Halgania species due to a contracted inflorescence, a funnel-shaped corolla or an ostensible lack of a female stage. Using light and scanning electron microscopy, we investigated traits referring to the floral architecture of Halgania and compared the flowers of different species. In all investigated species the anthers of the cone are connected via long, intertwined trichomes (denoted “capillinection”) both between the individual anthers and in the central stylar channel. The anther opening is functionally reduced to an apical pore by 1) capillinection and spatial compression of the thecal walls, leaving only small apical slits and 2) by anther appendages that unify the ten slits to a single pore. Halgania flowers are morphologically similar to each other and are buzz-pollinated. We conclude that they are all structurally and functionally matching the flowers of tomato, Solanum lycopersicum, and thus the concept of solanoid flowers as defined by Knut Fægri.10aFloral sonication10aPollinator guidance10aVibratile pollination1 aHolstein, Norbert1 aGottschling, Marc  uhttp://www.sciencedirect.com/science/article/pii/S0367253017334047
