Chiloscyphus parapilistipulus (Lophocoleaceae), a new species of liverwort from New Caledonia, with the typification of Lophocolea pilistipula. Candollea 75: 285–289. In English, English abstract. During a review of Lophocoleaceae types housed in G in the context of research on the liverworts of New Caledonia, a set of three specimens collected by Louise Le Rat in 1909 that were filed as types of Lophocolea pilistipula Steph. (≡ Chiloscyphus pilistipulus (Steph.) J.J. Engel & R.M. Schust.) turned out to be heterogeneous: the one originating from Île des Pins is fertile and corresponds to the protologue as well as Stephani's illustration of this taxon. This original material is designated here as lectotype of Lophocolea pilistipula. The two other specimens in G collected on Mount Dogny are sterile and exhibit some morphological differences from the designated lectotype material, namely the plants are large, with wider stems that have larger and broader leaves with smooth rather than crenulate margins, and that lack trigones. A new fertile collection from Mount Dogny was identified as belonging to Chiloscyphus Corda and is conspecific with the material collected from Mount Dogny over a century earlier. A new species, Chiloscyphus parapilistipulus Thouvenot, is described. It closely resembles Lophocolea pilistipula but differs from it by its larger size, smooth leaf margins, the dioicous sexuality and the ventro-lateral position of the gynoecia at the apex of short leafless branches.

New combinations for two species in the genus Synima (Sapindaceae, Cupanieae) from Queensland (Australia). Candollea 75: 241–244. In English, English abstract. Synima Radlk. is a small genus of Sapindaceae distributed in Australia, Indonesia (Moluccas and Western New Guinea) and Papua New Guinea with three species currently accepted. The genus can be recognized by its crested scales on the petals, a pericarp that dries thin and wrinkled, and the seed which has a fleshy, yellow-orange sarcotesta that is either small and basal or ± enclosing the seed. Previous taxonomic studies expressed doubts regarding the generic placement of two species belonging to the genus Sarcotoechia Radlk.: Sarcotoechia serrata S.T. Reynolds and Sarcotoechia heterophylla S.T. Reynolds. A phylogenetic framework has shown that Sarcotoechia is paraphyletic and Sarcotoechia serrata is sister to Synima. Further morphological evidence (e.g., crested petals) support the transfer of the latter two species to Synima and the new combinations are proposed here: Synima heterophylla (S.T. Reynolds) Callm. & Buerki and Synima serrata (S.T. Reynolds) Callm. & Buerki. A key to all species of Synima is presented.

New species of Memecylon (Melastomataceae) from Madagascar: treasures of the TEF Herbarium. Candollea 75: 219–239. In English, English and French abstracts. Memecylon L. (Melastomataceae, Olisbeoideae) is a widespread paleotropical genus of forest shrubs and small trees, and is one of the ten most species-rich genera of woody plants in Madagascar. In a previous treatment, Jacques-Félix recognized 78 species of Memecylon on the island, of which all are endemic and most are known from just one or two sites. The present work describes and illustrates nine new species of Memecylon from Madagascar (including Memecylon complanatum R.D. Stone, Memecylon convergens R.D. Stone, Memecylon fofifa R.D. Stone, Memecylon longipetiolatum R.D. Stone, Memecylon paraxenum R.D. Stone, Memecylon potamicum R.D. Stone, Memecylon pseudogaleatum R.D. Stone, Memecylon subchartaceum R.D. Stone, and Memecylon unguiculare R.D. Stone), based mainly on material received on loan from the FO.FI.FA Herbarium (TEF). The conservation status of each species is provisionally assessed in accordance with the IUCN Red List Categories and Criteria. Given the extensive anthropogenic deforestation of Madagascar, one must consider the possibility that Memecylon complanatum, Memecylon paraxenum, and Memecylon pseudogaleatum are already extinct since these three species have not been recollected within the last 50–60 years. Work is ongoing towards a comprehensive taxonomic revision of Memecylon in Madagascar.","PeriodicalId":55276,"journal":{"name":"Candollea","volume":"75 1","pages":"219 - 239"},"PeriodicalIF":0.6,"publicationDate":"2020-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42803908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Importance and characteristics of the Cyrno-continental taxa, and analysis of their absence outside Corsica. Candollea 75: 291–310. In French, English and French abstracts. Corsica contains a flora present on the European continent but absent from all the other large Mediterranean islands (Balearic Islands, Cyprus, Crete, Sardinia and Sicily). The study analyzes all the taxa of this flora called here Cyrno-continental and represented by 258 taxa (12 % of the native flora). Its characteristics (biological, biogeographical and chorological types, vegetation belts and habitats) are analyzed here and appear to be very different from those of the total native flora. This flora directly depends on the geographical characteristics of Corsica distinct from those of the other islands (latitude, reliefs, temperate vegetation belts in altitude) because 59.8 % of these taxa find their limits of distribution in Corsica. Some of them have found a postglacial refuge in Corsica, others have been able to establish themselves thanks to the great wealth of its habitats, notably humid. Others have limited distribution areas that have not allowed them to colonize other islands. Expansion capabilities, environmental change and chance also play a role in some cases.","PeriodicalId":55276,"journal":{"name":"Candollea","volume":"75 1","pages":"291 - 310"},"PeriodicalIF":0.6,"publicationDate":"2020-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47133357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two new genera of Sapindaceae (Cupanieae) from the southern Pacific: Lepidocupania and Neoarytera. Candollea 75: 269–284. In English, English abstract. Phylogenetic analyses of the family Sapindaceae inferred from nuclear and plastid sequence data have revealed a high level of para- and polyphyly at the subfamilial, tribal, and generic levels. A phylogenetic study focusing on taxa in the southern Pacific belonging to tribe Cupanieae has shown that the two most species-rich genera, Arytera Blume and Cupaniopsis Radlk., are polyphyletic. This study aims to clarify generic limits among the taxa currently placed in these two genera by identifying morphological features that support monophyletic groups suitable for recognition at the generic level. Specimens deposited in major herbaria holding material of these taxa were examined to complement extensive field observations. Careful consideration of morphological features in light of previous taxonomic treatments and the results of phylogenetic analyses enabled us to propose a re-aligned generic framework for Cupanieae in which two new genera are described to accommodate species previously placed in Arytera and Cupaniopsis: viz., Lepidocupania Buerki, Callm., Munzinger & Lowry (21 species) and Neoarytera Callm., Buerki, Munzinger & Lowry (4 species). A total of 25 new combinations are made, lectotypes are designated for nine names (two first step and seven second-step), and one new synonym is established. A key to the newly circumscribed genera Arytera and Cupaniopsis, along with allied genera, is provided, accompanied by information on the distribution and ecology of each species.
