All available phylogenetic evidence indicates that the rattan genus Calamus, the largest of all palm (Arecaceae) genera, is non-monophyletic and that the four remaining genera of subtribe Calaminae (Calameae: Calamoideae), Ceratolobus, Daemonorops, Pogonotium and Retispatha, are nested within it. This issue has not yet been adequately addressed in palm classifications, with recent authors preferring to wait for further phylogenetic evidence before revising the limits of the genera. Here, an alternative solution is proposed that is both pragmatic and phylogenetically robust. An expanded Calamus is recognised into which Ceratolobus, Daemonorops, Pogonotium and Retispatha are subsumed. This broad generic concept, which includes ca. 520 species, has practical advantages as it is more clearly defined by morphological and anatomical characters, and resolves potential biases introduced to recent eco-evolutionary research on palms by the non-monophyly of critical genera. Future phylogenetic research may yet provide an alternative means of delimiting these genera, but the broad sense Calamus proposed here is a justifiable alternative that can be adopted immediately. Nomenclatural synopses transferring currently accepted species of Ceratolobus, Daemonorops and Pogonotium to Calamus are provided, including 70 new combinations and 12 replacement names.

A synthesis of the present knowledge of the Spanish Peritelini is presented. Two new genera are separated from Peritelus auctt.: Euplister (type species: Peritelus susanae Seidlitz, 1866) and Pseudoperitelus (type species: Peritelus globulicollis Seidlitz, 1862). Thirteen new species are described from Spain: Meira gerundana, M. medae, M. tarraconensis, Pseudomeira baetica, P. eremita, P. lepida, Euplister andalusicus, E. frater, E. megalophthalmus, E. mimus, E. moroderi, E. trifolii, E. velazquezi. New combinations are: Euplister susanae (Seidlitz, 1866), E. hybridus (Seidlitz, 1871), E. setabensis (Hustache, 1921), E. magnicollis (Desbrochers, 1896), E. coniceps (Desbrochers, 1897), Pseudoperitelus senex (Boheman, 1834), P. globulicollis (Seidlitz, 1871), P. espanoli (Roudier, 1958) and P. lopezi (Hoffmann, 1961), and one new synonym is proposed: Simo cremieri (Boheman, 1842) = Peritelus maroccanus Pic, 1920, syn. n. One genus, Meira Jacquelin du Val, 1853, and two species, Gymnomorphus nigrans (Fairmaire, 1862) and Meirella florentina (Stierlin, 1884), are newly recorded from Spain, bringing the total number of Peritelini known from Iberia to ten genera and thirtysix species. Diagnoses, detailed descriptions and data on distribution and ecology, mostly unpublished, are provided for each species, and a catalogue, identification keys, distribution maps and figures of key anatomical characters are added for the Iberian species. Caenopsis Bach, 1854 is excluded from Peritelini and confirmed as belonging in Trachyphloeini.

Salacia comprises 200 species throughout the tropical countries. In Sri Lanka, five species of this genus S. chinensis, S. diandra, S. oblonga, S. reticulata and S. acuminatissima are recorded that are considered as the synonyms under S. diandra by Wadhwa in 1996 during the revision of genus. These species are very much similar in vegetative morphology and their flowering is irregular and rare. Due to these reasons, their proper identification and determination are difficult and identification of new combinations of taxonomic characters is necessary. A multivariate analysis was conducted for 98 distinct populations using 20 vegetative and 43 leaf anatomical characters including PCA, PCO, CA, SIMPER and correlation analysis. The results support the recognition of four phenetic groups, which corresponds to species S. chinensis, S. reticulata, S. oblonga and S. diandra. S. acuminatissima that was recognized by Kostermans (1992) was not supported by the analysis and formed a cluster together with S. diandra with no support as a separate cluster. The study failed to recognize any distinct vegetative characters to define these taxa but propose a combination of vegetative or leaf anatomical characters and also highlights the necessity of molecular data to supplement the vegetative and leaf anatomical data to resolve the ambiguity between the S. acuminatissima and S. diandra.

A new classification for subtribe Pterostylidinae (Orchidaceae) is formally described in which there is one genus, Pterostylis R.Br., two subgenera and 10 sections. Five new combinations are made for this classification at the ranks of subgenus and section, viz. Pt. subg. Oligochaetochilus (Szlach.) Janes & Duretto, Pt. sect. Parviflorae (Benth.) Janes & Duretto, Pt. sect. Pharochilum (D.L.Jones & M.A.Clem.) Janes & Duretto, Pt. sect. Stamnorchis (D.L.Jones & M.A.Clem.) Janes & Duretto and Pt. sect. Urochilus (D.L.Jones & M.A.Clem.) Janes & Duretto. Pt. ser. Parviflorae Benth. is lectotypified. To complete the revision, seven new species-level combinations are made for two species from Western Australia, one from New South Wales and four from Queensland, viz. Pt. anaclasta (D.L.Jones) Janes & Duretto, Pt. extranea (D.L.Jones) Janes & Duretto, Pt. pearsonii (D.L.Jones) Janes & Duretto, Pt. pedina (D.L.Jones) Janes & Duretto, Pt. sinuata (D.L.Jones) Janes & Duretto, Pt. timothyi (D.L.Jones) Janes & Duretto and Pt. thulia (D.L.Jones) Janes & Duretto.

The validity of the generic concept of Babingtonia Lindl. adopted by Bean (1997a) is tested in the light of molecular and morphological data. Molecular analyses support recognition of segregate genera, none of which is closely related to the type of the genus, Babingtonia camphorosmae, a western Australian species. Two genera, Sannantha and Kardomia, are described as new and a third genus, Harmogia, resurrected from synonymy; new combinations are provided in the new genera. A fourth group, consisting of ‘Babingtonia’ behrii and its allies, appears distinct but, as a predominantly southern group, with numerous western Australian representatives, is not treated further.

Generic Concept

AbstractA broad generic concept is adopted for Catillaria, and the following new combinations made: C. aphana (Nyl.) Coppins, C. modesta (Müll. Arg) Coppins (the basionym, Lecidea modesta Müll. Arg., being lectotypified), C. picila (Massal.) Coppins, and C. scotinodes (Nyl.) Coppins. Lecidea botryiza Nyl. ex Stirton is added to the synonymy of Micarea lutulata. Catillaria rhypodiza is transferred to Halecania, and a new, sorediate, corticolous species of that genus, H. viridescens Coppins & P. James, is described.

The generic delimitation of Polygonum Linnaeus (1753: 359) has been controversial, and interpreted differently by various authors, especially in the past (Meisner 1826, Gross 1913, Tzvelev 1987). Several morphological and anatomical characters, such as in pollen (Hedberg 1946), vegetative parts (Haraldson, 1978), flower (Ronse Decraene & Akeroyd 1988), and fruit (Ronse Decraene et al. 2000), have been considered in subdividing the heterogeneous genus Polygonum into a number of smaller groups, which was also supported by recent molecular studies (Sanchez et al. 2009, Sanchez et al. 2011, Schuster et al. 2011). Genera and tribes in the buckwheat family have been redefined (Sanchez et al. 2011) and Persicaria(Linnaeus 1753: 360) Miller (1754), which is formerly and popularly treated as synonym of Polygonum in tribe Polygoneae, has been placed in the redefined tribe Persicarieae (Sanchez et al. 2011). Many combinations were already proposed to accommodate these generic changes, but six Polygonum species in the Flora of China (Li et al. 2003), have not been transferred and the new combinations in Persicaria are still necessary. Information on the types (five holotypes and one lectotype here designated) and morphological notes are also provided.

Purpose Many tourism destinations are now facing the problem of overtourism, and destination management organisations (DMOs) are in search of an effective and sustainable solution. With this as a foundation, the purpose of this study is to identify factors causing overtourism at popular tourism destinations and to propose an alternative solution to overcome this phenomenon. Design/methodology/approach The research design is based on an inductive and a deductive approach. The paper draws its conclusion from secondary and tertiary data (literature review and online research). Findings The study shows that Trexit (tourism exit) is not a sustainable solution to overtourism and that an alternative strategy may be adopted to tackle this phenomenon. The overall outcome shows that if sociological factors, business factors, technological and economic factors are addressed, the effect of overtourism may be managed and controlled. Practical implications The findings of this piece of research refer to a Just-in-Time strategy for managing overtourism. The findings could be useful to practitioners, as the study proposes an alternative means to overcome overtourism and manage destinations without affecting visitor flow and profitability. Originality/value This research fulfils an existing research gap, as it proposes an alternative solution to tackle overtourism. The proposed model also helps to provide a broader insight of the dynamics surrounding overtourism at tourism destinations. In so doing, it advances the existing body of knowledge by providing new inputs to a topic that has not been discussed, namely, Trexit or tourism exit.

The taxonomic status of Metrosideros queenslandica, and related species from New Guinea, is reassessed on the basis of fundamental morphological and anatomical characters and these species are found to be more closely allied to Tristanin sens. str. than to Metrosideros sens. lat. The current classification of this group of species as Metrosideros subg. Mearnsia sect. Adnatae J. W. Dawson is rejected and a new genus, Thaleropia, is described and the new combinations T. queeirslandica, T. iteophylla and T. hypargyrea made.
