A name (Eremogone loisiae) is provided for those plants from northern Utah and southeastern Idaho that have gone under the misapplied name Eremogone kingii subsp. uintahensis. Eremogone loisiae, named in honor of Lois A. Arnow, is distinguished from E. kingii by its longer and narrower, flexuous leaves and its longer sepals, petals, styles, capsules, and seeds.

During preparation of manuscript for volume 2A of Intermountain Flora, we recognized the need to publish 11 new combinations and three second-step lectotypifications. The new combinations are: Eremogone fendleri var. plateauensis, E. fendleri var. porteri, E. fendleri var. brevicaulis, and E. kingii var. compacta (Caryophyllaceae), Atriplex gardneri var. robusta (Chenopodiaceae), Corydalis caseana var. brachycarpa (Fumariaceae), Claytonia parviflora var. utahensis (Montiaceae), Argemone parva and Eschscholzia californica var. mexicana (Papaveraceae), and Aquilegia micrantha var. loriae and Ranunculus adoneus var. caespitosus (Ranunculaceae). Second-step lectotypifications are provided for Talinum confertiflorum and Talinum pygmaeum (Montiaceae) and Platystemon termini (Papaveraceae).

Three new species and two new varieties of Mentzelia belonging to the multistemmed subshrub group of section Bartonia are described. Typical of the group, they are narrow endemics occurring in relatively barren clay soils in the Intermountain Region of interior western U.S. Mentzelia tiehmii and Mentzelia argillicola are from Nevada, Mentzelia memorabalis from northern Arizona, Mentzelia multicaulis variety uintahensis from northeastern Utah and northwestern Colorado, and Mentzelia multicaulis variety flumensevera from central Utah.

Nevada holmgrenii was originally described by Rollins as aSmelowskia, but based on phenetic similarities it appears to be more closely related to the arctic/alpine generaBraya andEutrema. It is, however, sufficiently distinct from these genera to be planced in a nonotypic genus,Nevada.

Phylogenetic hypotheses for the largely South African genus Pelargonium L'Hér. (Geraniaceae) were derived based on DNA sequence data from nuclear, chloroplast and mitochondrial encoded regions. The datasets were unequally represented and comprised cpDNA trnLF sequences for 152 taxa, nrDNA ITS sequences for 55 taxa, and mtDNA nad 1 b/c exons for 51 taxa. Phylogenetic hypotheses derived from the separate three datasets were overall congruent. A single hypothesis synthesising the information in the three datasets was constructed following a total evidence approach and implementing dataset specific stepmatrices in order to correct for substitution biases. Pelargonium was found to consist of five main clades, some with contrasting evolutionary patterns with respect to biogeographic distributions, dispersal capacity, pollination biology and karyological diversification. The five main clades are structured in two (subgeneric) clades that correlate with chromosome size. One of these clades includes a "winter rainfall clade" containing more than 70% of all currently described Pelargonium species, and all restricted to the South African Cape winter rainfall region. Apart from (woody) shrubs and small herbaceous rosette subshrubs, this clade comprises a large "xerophytic" clade including geophytes, stem and leaf succulents, harbouring in total almost half of the genus. This clade is considered to be the result of in situ proliferation, possibly in response to lateMiocene and Pliocene aridification events. Nested within it is a radiation comprising c. 80 species from the geophytic Pelargonium section Hoarea , all characterised by the possession of (a series of) tunicate tubers.

A closely related group of Great Basin endemic dradas,Draba cusickii O. E. Schulz,D. sphaeroides Payson, andD. pedicellata (Rollins & R. A. Price) Windham, are described, keyed, and discussed in order to putD. pedicellata var.wheelerensis N. H. Holmgren, var. nov. in perspective.Draba cusickii is endemic to Steens Mountain of southeastern Oregon, andD. sphaeroides is known only from three mountain ranges in Elko County, Nevada, whereasD. pedicellata is more widespread in mountain ranges of eastern Nevada in Elko, Eureka, Nye, and White Pine counties.Draba pedicellata var.pedicellata occupies most of the range of the species, with var.wheelerensis being restricted to the Snake Range, just to the east of the range of the typical variety.

Voucher specimens for the plant material (Aronia melanocarpa L. 1753 "Nero" No 2-1485, determinator: Goran Anačkov) were confirmed and deposited at the Herbarium of the Department of Biology and Ecology -BUNS Herbarium, Faculty of Natural Sciences, University of Novi Sad (Holmgren and Holmgren, 2003). Aerial parts of the plant (berries, leaves and stems) were stacked in a crate with perforated bottom, in order to ensure air flow. ...

... The ongoing efforts of the Flora of North America (FNA 1993+) project to standardize species circumscriptions and nomenclature transcends the more fragmented data contained in state floras such as Weber and Wittmann (2012), Dorn (2001), and Allred and Ivey (2012). The recently completed Intermountain Flora (Cronquist et al. 1972;Cronquist et al. 1977Cronquist et al. , 1989Cronquist et al. , 1997Cronquist et al. , 1994Cronquist et al. 1984;Holmgren et al. 2005;Holmgren et al. 2012) illustrates what can be achieved on a physiographic scale. There are a few alpine specific checklists for small areas within the Rocky Mountain Cordillera (Little 1941;Johnson & Billings 1962;Spence & Shaw 1981;Rundel et al. 2008) but not for the entire Southern Rocky Mountain Region. ...

... Seeds of Gentianopsis barbellata have also been described as papillate (Cronquist et al. 1984;Engelmann 1878;Gillett 1957), although it is excluded from the monocarpic clade. In our images of G. barbellata obtained using low vacuum mode, the outer periclinal walls are slightly collapsed and do not appear to protrude at all ( Figure 2C); however, in micrographs taken using high vacuum conditions, outer periclinal walls of this species appear slightly protruding (data not shown) although not to the extent seen in seeds of the monocarpic clade. ...

... Below the genus level, variation in these characters is important in differentiating among closely related species for which macromorphological differences are scarce or difficult to interpret. Indeed, these characters have been used to differentiate species within many genera, including Allium (Alliaceae; Fritsch et al. 2006), Ephedra (Ephedraceae; Ickert-Bond and Rydin 2011), Frailea (Cactaceae; Metzing and Thiede 2001), Lathyrus (Fabaceae; Güneş and Ali 2011), and Mentzelia (Loasaceae; Thompson and Prigge 1986;Holmgren and Holmgren 2002;Schenk and Hufford 2010). Tes-tal microsculpturing traits have also been used to infer deeper evolutionary relationships within families but with mixed success (e.g., Barthlott 1981;Shetler and Morin 1986;Johnson et al. 2004;Zhang et al. 2005;Cupido et al. 2011;Kasem et al. 2011;Sousa-Baena and Menezes 2014;Gunathilake et al. 2015). ...
