ABSTRACT Recent studies have demonstrated that conflict is common among gene trees in phylogenomic studies, and that less than one percent of genes may ultimately drive species tree inference in supermatrix analyses. Here, we examined two datasets where supermatrix and coalescent-based species trees conflict. We identified two highly influential “outlier” genes in each dataset. When removed from each dataset, the inferred supermatrix trees matched the topologies obtained from coalescent analyses. We also demonstrate that, while the outlier genes in the vertebrate dataset have been shown in a previous study to be the result of errors in orthology detection, the outlier genes from a plant dataset did not exhibit any obvious systematic error and therefore may be the result of some biological process yet to be determined.

    New Cultivars Keywords: Pinguicula ‘Riva’, Drosera binata ‘Ghost’, Nepenthes ampullaria ‘Black Widow’, Nepenthes ampullaria ‘Caramel Candy Stripe’, Nepenthes ampullaria ‘Lime Delight’, Nepenthes ampullaria ‘Chocolate Delight’, Nepenthes ampullaria ‘Cherry Delight’, Nepenthes ampullaria ‘Bronze Delight’. Pinguicula ‘Riva’ Submitted: 22 February 2018 The parents of Pinguicula ‘Riva’ (Fig. 1) are P. agnata (with scented flowers) × P. gigantea (to the best of my knowledge; the second parent may have been a P. gigantea × P. emarginata). This cross was done and the resulting seed germinated in late 2013 by me in San Francisco, California. This particular plant made its specialness apparent after about 2 years of growth under lights when it began flowering. The flower is approximately 2 cm wide by 2.5 cm long and is white with a bright yellow center which is surrounded by a flaring purple ring. The petals are 1 cm long, 7-9 mm wide, slightly ruffled, and the top 2 petals have irregular slightly serrated upper margins. The spur is 12 mm long, green and straight. The flower stalk is 18-20 cm long. And, the flower is scented, quite heavily in warmer conditions. The flower does not produce pollen or seed so it is sterile. The leaves of the plant are nice as well, ranging from 4-5.5 cm long and about 3 cm wide. The leaf shape is oblong egg-shaped with the rounded end distal from the central growth point. The color of the leaves ranges from pale green with burgundy tinting and margins to muted burgundy with green undertones. The margins of the leaf are slightly upturned.

    Technical Refereed Contribution Several pygmy Sundew species possess catapult-flypaper traps with repetitive function, indicating a possible evolutionary change into aquatic snap traps similar to Aldrovanda Siegfried R. H. Hartmeyer and Irmgard Hartmeyer • Weil am Rhein • Germany • s.hartmeyer@ t-online.de • www.hartmeyer.de Keywords: Drosera, pygmy Sundew, Aldrovanda, Dionaea, Droseraceae, Collembola, carnivorous plant, catapult-flypaper trap, snap trap, snap-tentacle, functional morphology, phylogeny. Abstract: Approximately 50 species of pygmy Sundews (genus Drosera, section Bryastrum) occur in the South of Australia and one each in New Zealand (D. pygmaea) and Venezuela (D. meristo- caulis). They grow mainly as small stemless rosettes possessing minute trapping leaves of 1-2 mm diameter with prominent marginal tentacles, or have elongated erect stems. The caulescent species possess only mucus-producing tentacles that are most effective in capturing small flying insects. The acaulescent species in contrast are specialized on crawling prey (Verbeek & Boasson 1993) and have developed mucus-free snap-tentacles (Fig. 1), able to bend surprisingly rapidly towards the leaf center. They lift prey like, e.g. springtails (Collembola) from the ground and carry it with a 180°-movement from the periphery of the plant onto the sticky leaf. Our examinations brought to light that several small species of section Bryastrum are able to catapult small animals even within fractions of a second. If the whole leaf is touched, several or even all marginal tentacles perform such bending movements simultaneously. We documented this behavior on video, featured on our film “Catapults in Pygmyland” on YouTube (www.youtube.com/watch?v=5k7GYGibdjM). Our results prove that more than only one species in the genus Drosera possess rapidly moving catapult-flypaper traps and that the examined pygmy catapults show a further specialization and function repeatedly (in contrast to the one-shot snap tentacles of D.

This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups.

    Drosera regia Stephens Nigel Hewitt-Cooper • The Homestead • Glastonbury Road • West Pennard • Somerset, BA6 8NN • UK • [email protected] Keywords: Cultivation: Drosera regia Much has been written about this interesting species of sundew over the years, both in the popu- lar literature and indeed on-line in more recent times. Much of what is written would serve to dis- courage the average hobbyist from attempting cultivation, and as a result until surprisingly recently Drosera regia was scarcely seen. The truth however, is that this plant is generally easy to grow suc- cessfully, and once established is a long lived perennial which can attain huge dimensions. Although it is becoming commoner in peoples collections, it remains exceedingly rare in the wild, with one of the smallest and most endangered natural ranges of any Drosera species. It is found in a single remote valley at Bainskloof, near Cape Town in South Africa at an altitude of 600-900 m, where it exists as two separate colonies, one of which could possibly already be extinct (pers. comm.) It has been suggested that the two colonies differ by one having slightly broader leaves. Here they are found growing amongst dense grasses which make them somewhat difficult to find, and indeed they compete with the surrounding vegetation by producing their sword-shaped lanceolate leaves up to 50 cm in length–the largest of any Drosera. At their bases the leaves can be up to 2 cm wide, gradually tapering to a point at their apex, with many large tentacles up to 4 mm in length, each topped with a generous droplet of mucilage found on the upper surface of the leaf, facing inwards toward the growth point (see Fig.

Barrett 1National Herbarium of New South Wales, Royal Botanic Gardens and Domain Trust, Mrs Macquaries Road, Sydney, NSW 2000, Australia. 2Department of Biological Science, University of Queensland, St Lucia, Qld 4076, Australia Author for correspondence: [email protected] Abstract Across tropical northern Australia 14 Drosera species are recognised within the D. petiolaris complex. The complex is placed in section Lasiocephala; a group of perennial sundews mostly characterised by an indumentum of white hairs upon the petiole. Here we describe a new species for the complex, D. stipularis Baleeiro, R.W.Jobson & R.L.Barrett, which is known only from white-sand habitats on Cape York Peninsula, Queensland. The new species is allied to D. petiolaris R.Br. ex DC. and D. lanata K.Kondo. Introduction Drosera petiolaris R.Br. ex DC. was first collected at Endeavour River, Queensland (Banks and Solander s.n., BM) and was described by Robert Brown (in de Candolle 1824). The type specimen was evidently collected very late in the season, and has little fertile material present. The species was later found to be part of a morphologically variable complex distributed across northern Australia and Papua New Guinea.

Introduction It has long been known that the genus Drosera, together with the family (Droseraceae) and the order containing it, Nepenthales (¼ “non-core Caryophyllales” sensu APG III, 2009), are characterized by the frequent presence of acetogenic naphthoquinones (Hegnauer, 1969, 1990; Schlauer, 1997). This is in contrast to Caryophyllales (“core Caryophyllales”), in which Nepenthales are frequently included (APG III, 2009; Chase and Reveal, 2009), but that are devoid of these metabolites and that frequently contain betalains instead.
