  abstract  = {Sansevieria pfennigii, which to date has been a doubtful species, is confirmed as extant by a recent collection from the Lindi Region in southern Tanzania. The original description of the species, which is based on herbarium material only, is here emended based on additional observations recorded from living plants, including fruits that were previously unknown. Sansevieria pfennigii distinguishes from S. canaliculata, to which it was repeatedly assigned, by its capitate instead of elongate inflorescence, rough rather than smooth leaves, non-pungent instead of pungent leaf tips, dull green leaf colour, more delicate overall appearance, alongside other traits. The difference in inflorescence architecture indicates that these species belong to different groups within Sansevieria and are not closely related; the closest relatives of S. pfennigii are probably S. fischeri and S. stuckyi. Sansevieria pfennigii occurs on well-drained soil in forests, close to S. canaliculata populations. According to the extent of the population seen and the species' overall rarity, it is tentatively assessed as critically endangered.},

  abstract  = {Recent molecular phylogenetic reconstruction of the monocot Hypoxidaceae implies that the genus Curculigo is non-monophyletic. Curculigo seychellensis occurs on the Seychelles islands and is part of an isolated though geographically well-defined clade. However, Curculigo seychellensis differs in a wide range of character-states from other species of Curculigo and from the genus Hypoxidia, representing the sister clade of C. seychellensis. Therefore, we here propose a new-though monotypic-genus, endemic to the Seychelles: Friedmannia. A detailed reasoning combined with a whole set of new data is presented. A neotype for the genus and the species is designated here.},

  abstract  = {Phylogenetic relationships of the monocot family Hypoxidaceae (Asparagales), which occurs mainly in the Southern Hemisphere, were reconstructed using four plastid DNA regions (rbcL, trnL intron, trnL-F intergenic spacer, and trnS-G intergenic spacer) for 56 ingroup taxa including all currently accepted genera and seven species of the closely related families Asteliaceae, Blandfordiaceae, and Lanariaceae. Data were analyzed by applying parsimony, maximum likelihood and Bayesian methods. The intergenic spacer trnS-G - only rarely used in monocot research - contributed a substantial number of potentially parsimony informative characters. Hypoxidaceae consist of three well-supported major clades, but their interrelationships remain unresolved. Our data indicate that in the Pauridia clade one long-distance dispersal event occurred from southern Africa to Australia. Long-distance dispersal scenarios may also be likely for the current distribution of Hypoxis, which occurs on four continents. In the Curculigo clade, the present distribution of Curculigo s.s. on four continents could support a Gondwanan origin, but the level of divergence is too low for this hypothesis to be likely. The main clades correspond well with some floral characters, habit and palynological data, whereas chromosomal data exhibit plasticity and probably result from polyploidization and subsequent dysploidy and/or aneuploidy. Evolutionary flexibility is also suggested by the number of reported pollination syndromes: melittophily, myophily, sapromyophily, and cantharophily. Based on our phylogenetic results, we suggest cautious nomenclatural reorganization to generate monophyly at the generic level.},
