A new species of Pseudoblepharispermum (Asteraceae, Plucheeae) from NE Somalia. Candollea 75: 183–188. In English, English abstract. A new species of the genus Pseudoblepharispermum Lebrun & Stork (Asteraceae), up to now including Pseudoblepharispermum bremeri Lebrun & Stork and Pseudoblepharispermum mudugense Beentje & D.J.N. Hind, is described from two herbarium specimens housed at FT, collected in 1954 near the Indian Ocean coast of Bari Region, NE Somalia. These specimens formed an unidentified remaining part of a collection given to FT by the Italian geologists G. Merla, A. Azzaroli and V. Fois, who had led a geologic expedition in the former Migiurtinia (current Bari Region) on behalf of an Italian oil company. The new species Pseudoblepharispermum tuddense Baldesi & Pignotti is more similar to Pseudoblepharispermum bremeri from S Ethiopia than to Pseudoblepharispermum mudugense from central Somalia. Close examinations of macro- and micro-characters were carried out for the new species and compared with the features of Pseudoblepharispermum bremeri. Diagnostic characters are listed to support the taxonomic distinction between the new species and Pseudoblepharispermum bremeri.

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":null,"pages":null},"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}
