What is this page?
This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.
It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.
If you're a ResearchGate member, you can follow this page to keep up with this author's work.
If you are this author, and you don't want us to display this page anymore, please let us know.

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, capsule...
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 gardner...
Lectotypes are selected for 10 names inHypericum (Clusiaceae),Elatine (Elatinaceae),Arctostaphylos andVaccinium (Ericaceae),Androsace (Primulaceae), andViola (Violaceae).
A lectotype for the nameMentzelia multiflora var.integra is selected and a new combination inMentzelia (Loasaceae) is made. A key to the varieties ofMentzelia marginata is included.
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 memo...
Nineteen additional herbaria have been called to our attention since the last installment of this series was published in February 2002. Information on these herbaria is presented below in alphabetical order by country. This brings the total number of herbaria added since the publication of Edition 8 to 393. Information for 3175 herbaria and 9623 p...
A new variety ofDraba oreibata, var.serpentina, is described, illustrated, and discussed.
Jamesia (Hydrangeaceae) is endemic to western North America from the southern Rocky Mountains in southeastern Wyoming and Colorado
west across the Great Basin to the southern Sierra Nevada and south through New Mexico and southeastern Arizona to Chihuahua
and Nuevo León. Its distinctiveness and Oligocene fossil record suggest that it is an old genu...
Caulanthus barnebyi from northern Nevada is described, illustrated, and compared with its nearest relative,C. glaucus S. Wats.
Asclepias welshii, restricted to the Coral Pink Sand Dunes of southern Utah, is described and illustrated. Its relationship to other species
of seriesRoseae is discussed.

... Aronia (Aronia melanocarpa) was collected in the area of southern Serbia (territory of Leskovac, Latitude: 42°59′ 46.9536″ N; Longitude: 21°56′ 38.5224″ E) in August 2015. 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. ...
... Little was previously known about E. tiehmii beyond surveys of associated plant species, general site characteristics, and inferences based on its taxonomic group and extremely limited range (Morefield, 1995;Tiehm, 1994). Eriogonum is the second-most speciose genus in Nevada and shows wide variation in its ecological role and habitat preferences (Cronquist et al., 1977;Holmgren et al., 1966;Consortium of Intermountain Herbaria, https:// intermountainbiota.org/). Eriogonum species exhibit reproduction modes that vary between primarily selfpollinated and primarily outcrossing, and many species in this genus are known to support extensive pollinator communities (James et al., 2014). ...
... 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. ...
... Location, morphology, ecology, and agronomy data were also collected in situ. Herbarium specimens were consulted from five herbaria [BM, BR, K, P, WAG; codes follow Holmgren et al. (1990) and Thiers (2019)] for additional information, including habitat, vegetation, environment, morphology, cultivation history and trade. ...
... 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). ...
