“…The origins of Visceae have been controversialeither being considered of Laurasian (Barlow, 1983b) or Gondwanan origin (Vidal-Russell & Nickrent, 2008). A more recent study by Maul & al. (2019) reconstructed the biogeographic history of Viscum L. and related genera (including Korthalsella).…”

“…Like Korthalsella, Viscum has a complex biogeographic history. The genus originated in Africa, but dispersed to Australia, Asia, and Europe at different times during its evolutionary history (Maul & al., 2019). Most of these events correlate with known migratory bird patterns, although some (e.g., to Australia) do not.…”

“…For two individuals (K175 and K181), only one new sequence was generated. Molecular phylogenetic studies of Santalales indicate that Korthalsella is most closely related to Ginalloa , a small Indomalayan genus with five species (Nickrent & Soltis, ; Der & Nickrent, ; Mathiasen & al., ; Nickrent & al., ; but see also Maul & al., ). A further 42 sequences were downloaded from GenBank (Molvray & al., ; Papadopulos & al., ) (Appendix ) or taken from our recent study of Korthalsella in New Zealand (Sultan & al., ), for a total of 106 sequences analysed phylogenetically (53 in each of the plastid and ITS datasets).…”

Korthalsella (Santalaceae, tribe Visceae) mistletoes are hemiparasitic plants that are widespread on islands and continental regions around the Indian and Pacific Oceans. In this study, we add key taxa to a previously generated dataset to produce a more inclusive phylogenetic analysis of the genus. The resulting nuclear ITS and plastid trnL‐F phylogenies reveal that the historical sectional classifications based on morphology are not supported. Instead, it appears that widespread morphological parallelism has occurred throughout Korthalsella. Geographical distribution seems to be a better indicator of phylogenetic relatedness as species found in the same geographic region, island or island group generally are more closely related to one another than species sharing similar morphological characters in other areas. We find greater support for recognition of species as local endemics rather than wide‐ranging taxa. Given these results, taxonomic changes that recognise previously described taxa are proposed, but other changes will require further study of broadly distributed taxa.

PREMISE OF THE STUDY:The sandalwood order (Santalales) includes members that present a diverse array of inflorescence types, some of which are unique among angiosperms. This diversity presents not only interpretational challenges but also opportunities to test fundamental concepts in plant morphology. Here we used modern phylogenetic approaches to address the evolution of inflorescences in the sandalwood order. METHODS:Phylogenetic analyses of two nuclear and three chloroplast genes were conducted on representatives of 146 of the 163 genera in the order. A matrix was constructed that scored nine characters dealing with inflorescences. One character, "trios", that encompasses any grouping of three flowers (i.e., both dichasia and triads) was optimized on samples of the posterior distribution of trees from the Bayesian analysis using BayesTraits. Three nodes were examined: the most recent common ancestors of (A) all ingroup members, (B) Loranthaceae, and (C) Opiliaceae, Santalaceae s.l., and Viscaceae. KEY RESULTS:The phylogenetic analysis resulted in many fully resolved nodes across Santalales with strong support for 18 clades previously named as families. The trios character was not supported for nodes A and C, whereas it was supported for node B where this partial inflorescence type is best described as a triad. CONCLUSIONS: Essentially every major inflorescence type can be found in Santalales; however, the dichasium, a type of partial inflorescence, is rarely seen and is not plesiomorphic for the order. In the family Erythropalaceae, inflorescences are mostly in small, axillary fascicles or cymes. Successive families show both cymose and racemose types and compound systems (e.g., thyrses). Inflorescences in Amphorogynaceae and Viscaceae are not dichasial and in general are difficult to compare to "standard" inflorescences.

Parasites on parasites: hyper‐, epi‐, and autoparasitism among flowering plants

All living organisms engage in parasitic relations, as either parasites or hosts, and these interactions play an essential role in biological evolution and the functioning of the biosphere (Combes, 2001). Even among photosynthetic organisms, parasitic interactions are often established by both algae and land plants (Oborník, 2019). The most widespread form of parasitism among plants is characterized by the ability to develop a specialized organ called the haustorium (Kuijt, 1969). This organ differentiates the species commonly referred to as parasitic flowering plants from other non-autotrophic plants that require fungal hosts or partners to fulfill their nutritional needs (Feild and Brodribb, 2005; Merckx et al., 2009). Usually developed soon after germination, the haustorium enables attachment AJB REVIEWS
