Box 2732, Kent Town, South Australia 5071 E-mail: [email protected] b 13 Park Road, Bulli, New South Wales 2516 E-mail: [email protected] Abstract Increased collections from the Hibbertia-rich vicinity of Sydney, New South Wales, prompted a survey of rarer species to publicise the need for more information ahead of the rapid urban spread. Many of these species were previously misunderstood or are listed as rare and endangered. Thirteen new taxa (in bold) are described and discussed in context with the following seventeen taxa within seven different species groups: 1. H. acicularis group: H. woronorana Toelken; 2.

Phylogeny, Biogeography, and Morphological Ancestral Character Reconstruction in the Mediterranean Genus Fumana (Cistaceae)

Received 9 July 2018; Accepted 22 December 2019; Article first published online 31 December 2019 Abstract Fumana is a diverse genus of the Cistaceae family, consisting of 21 currently accepted species. In this study, nuclear (ITS) and plastid (matK, trnT‐L) molecular markers were used to reconstruct the phylogeny and to estimate divergence times, including 19 species of Fumana. Phylogenetic analyses (Bayesian Inference, Maximum Parsimony and Maximum Likelihood) confirmed the monophyly of Fumana and did not support the infrageneric divisions previously established. The results support four main clades that group species that differ in vegetative and reproductive characters. Given the impossibility to define morphological characters common to all species within the clades, our proposal is to reject infrageneric divisions. Molecular dating and ancestral area analyses provide evidence for a Miocene diversification of the genus in the north‐western Mediterranean. Ancestral state reconstructions revealed ancestral character states for some traits related to xeric and arid habitats, suggesting a preadaptation to the Mediterranean climate. -

Mucilage Secretion: an Adaptive Mechanism to Reduce Seed Removal by Soil Erosion?
bs_bs_banner Biological Journal of the Linnean Society, 2014, 111, 241–251. With 2 figures Mucilage secretion: an adaptive mechanism to reduce seed removal by soil erosion? MEIKE ENGELBRECHT*, ESTHER BOCHET and PATRICIO GARCÍA-FAYOS Centro de Investigaciones sobre Desertificación (CIDE) – (CSIC-UV-GV), Carretera Moncada – Náquera, Km 4.5, Apartado Oficial, 46113 Moncada, Valencia, Spain Received 12 July 2013; revised 13 September 2013; accepted for publication 13 September 2013 Diaspores of many plant species inhabiting open vegetation in semi-arid environments secrete mucilage after wetting (myxospermy) that glues the diaspores to the ground and prevents movement when the mucilage dries. In the present study, we test whether mucilage secretion can be considered as a selective response to soil erosion in plant species inhabiting semi-arid environments. We relate the amount and type of mucilage secretion by seeds of Helianthemum violaceum and Fumana ericifolia (Cistaceae) to the number of raindrop impacts needed to remove these seeds after gluing them with their own mucilage to the ground and also the time that these seeds resist water run-off without detaching. We also compare the amount of seed mucilage production by plants growing in habitats without erosion and plants affected by severe erosion by fitting mixed effect models. Our results show an important phenotypic variation in the amount of mucilage secretion in both species, although it is suggested that the effect of mucilage secretion in the rate of seed removal by erosion is species- and mechanism-dependent. For F. ericifolia, the amount of mucilage secreted by the seeds is directly proportional to their resistance to raindrop impacts and is positively related to the intensity of the erosive processes that the plants experience. -

Pollen tube growth rates (PTGRs) of angiosperms are exceptionally rapid, a pattern 25 attributed to more effective haploid selection under stronger pollen competition. Paradoxically, 26 whole genome duplication (WGD) has been common in angiosperms but rare in gymnosperms. -
