Carnivorous Plant Newsletter V44 N4 December 2015
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. -

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. -

Nejprve především morfologie, anatomie a fyziologie jejich pastí, v posledních desetiletích jsou však terčem intenzivního výzkumu i jejich genomy. Ačkoli se masožravé rostliny vyvinuly nezávisle v různých kládech krytosemenných rostlin, je evoluce masožravosti obecně podmíněná především nedostatkem živin za současného dostatku vody a světla. Několik nezávislých kládů tak sdílí obecně definované podmínky, které mohou ovlivňovat i vlastnosti jejich genomů, což z masožravých rostlin dělá zajímavou skupinu pro různé srovnávací analýzy. -
Phylogeny of the Sundews, <I>Drosera</I> (Droseraceae

PHYLOGENY OF THE SUNDEWS, DROSERA (DROSERACEAE), BASED ON CHLOROPLAST RBCL AND NUCLEAR 18S RIBOSOMAL DNA SEQUENCES1 FERNANDO RIVADAVIA,2,3 KATSUHIKO KONDO,4 MASAHIRO KATO,3 AND MITSUYASU HASEBE2,5,6 2National Institute for Basic Biology, Okazaki 444-8585, Japan; 3Department of Biological Sciences, Graduate School of Science, University of Tokyo, Tokyo 113-0033, Japan; 4Laboratory of Plant Chromosome and Gene Stock, Faculty of Science, Hiroshima University, Higashi-Hiroshima 739-8526, Japan; and 5Department of Molecular Biomechanics, School of Life Science, The Graduate University for Advanced Studies, Okazaki 444-8585, Japan The sundew genus Drosera consists of carnivorous plants with active ¯ypaper traps and includes nearly 150 species distributed mainly in Australia, Africa, and South America, with some Northern Hemisphere species. In addition to confused intrageneric clas- si®cation of Drosera, the intergeneric relationships among the Drosera and two other genera in the Droseraceae with snap traps, Dionaea and Aldrovanda, are problematic. We conducted phylogenetic analyses of DNA sequences of the chloroplast rbcL gene for 59 species of Drosera, covering all sections except one. These analyses revealed that ®ve of 11 sections, including three monotypic sections, are polyphyletic. Combined rbcL and 18S rDNA sequence data were used to infer phylogenetic relationships among Drosera, Dionaea, and Aldrovanda. This analysis revealed that all Drosera species form a clade sister to a clade including Dionaea and Aldrovanda, suggesting that the snap traps of Aldrovanda and Dionaea are homologous despite their morphological differences. MacClade reconstructions indicated that multiple episodes of aneuploidy occurred in a clade that includes mainly Australian species, while the chromosome numbers in the other clades are not as variable. -

Only two different chloroplast haplotypes among 15 A. vesiculosa accessions Available online 5 December 2009 from Africa, Australia, Europe, and Japan were found, generally distinguishing European and non- European plants, with two exceptions. Genetic variation observed in A. vesiculosa appears to be even Keywords: lower than in other aquatic species with a similar world-wide distribution. A recent bottleneck followed Aldrovanda vesiculosa by long-distance dispersal by water birds or low mutation rates could be responsible for the observed Droseraceae Genetic variation genetic uniformity. Estimation of genetic distances based on six chloroplast intergenic regions led to the Mitochondrial and chloroplast marker conclusion that the chloroplast genome of A. -

Drosera Pauciflora – the Queen of the Sundews
Technical Refereed Contribution Drosera pauciflora – the queen of the sundews Robert Gibson • 5 Kristen Close • Cardiff Heights • NSW 2285 • Australia • robert.gibson@ environment.nsw.gov.au Drosera pauciflora Banks ex DC is a flat-rosetted sundew endemic to the Western Cape of South Africa which produces flowers up to 6 cm diameter that are the largest in the genus (Obermeyer 1970). These magnificent flowers make Drosera pauciflora an apt queenly partner to the king sun- dew, Drosera regia. Drosera pauciflora is perhaps better known from plants in cultivation than in the wild, to help rectify this I present information from field and herbarium studies to give this species more context. Drosera pauciflora (Fig. 1) has been described by Obermeyer (1970: p. 196) to which I add the following details: The lower surface of the leaf have three to five raised longitudinal veins that are most conspicuous in the basal half of the leaf. Two small filiform stipules to 3 mm long are present on either side of the lowermost edge of the leaf. Plants can produce a second scape in spring under favorable conditions that extend the growing season, and flowers have either white or pink – purple petals. Each style segment is bifurcated near its apex into the stigma which comprises a fan-shaped array of about 20 filiform to narrowly obcuneate segments (Fig. 1(a, b)). In cultivation the flowers do not set seed when self-pollinated but will set seed when crossed with other clones of D. pauci- flora, or even some forms of the closely-related D.
