An illustration is provided. The species is named in honor of the late Seville Flowers, professor of botany at the University of Utah.       

A new perennial species of Gilia (Polemoniaceae) from Utah

Gilia tenuis Smith & Neese is a previously undescribed species from Emery and Sevier counties, Utah, apparently closely related to G. caespitosa Gray and G. subnuda Torr. ex Gray. It is distinguished from these species by its possession of a combination of characters including perennial, multicipital habit, lobed basal leaves, and small, pale blue flowers.     

Typification and nomenclature of Hedysarum boreale Nutt. (Leguminosae)

The holotype of Hedysarum boreale Nutt. is convarietal with natural populations now known as Hedysarum boreale Nutt. var. cinerascens (Rydb.) Rollins instead of var. boreale. The new combination Hedysarum boreale Nutt. var. rivulare (Williams) Northstrom is proposed for populations formerly known as var. boreale.     

Endangered, threatened, extinct, endemic, and rare or restricted Utah vascular plants

The status of 382 vascular plant taxa with distribution in Utah is presented. Some 66 species are possibly endangered, 198 threatened, 7 extinct, and 20 extirpated within the state; 4 species have questionable taxonomic status. Included in the list are nearly 225 species of endemic plants, many of which are among the possibly endangered, threatened, and extinct or extirpated plants. Bibliographic citations, type locality, status, and distribution by counties is included for each species or infraspecific taxon. Two new species are described: Psoralea pariensis and Eriogonum natum. One new name, Astragalus barnebyi, is proposed; and one new variety, Eriogonum umbellatum var. deserticum, is proposed. The following new combinations are made: Cycladenia humilis var. jonesii; Aralia racemosa ssp. bicrenata; Heterotheca jonesii; Hymenoxys depressa; Xanthocephalum sarothrae var. pomariense; Thelypodium integrifolium var. complanatum; Thelypodium sagittatum var. ovalifolium; Arenaria kingii var. plateauensis; Psorothamnus thompsonae; Najas caespitosus; Oenothera gouldii; Eriogonum corymbosum var. revealianum; Penstemon humilis var. obtusifolius; Penstemon lentus var. albiflorus; and Viola purpurea var. charlestonensis.       

New variety of Yucca harrimaniae (Agavaceae) from Utah

Yucca harrimaniae var. sterilis Neese & Welsh is named and described from the Uinta Basin of Utah. The plant is strongly rhizomatous, evidently sterile, and has limber, sparingly filiferous leaves that tend to recline on the ground.         

Three naturally occurring Penstemon hybrids

Three wild Penstemon hybrids are documented herein: Penstemon clevelandii × spectabilis, P. centranthifolius × spectabilis , and P. centranthifolius × eatonii . Each putative hybrid was compared to its respective parental species using manifold floral and vegetative characters for which the parents differed. For each hybrid hypothesis, characters were counted as being intermediate or not intermediate. There were significantly more intermediate characters in all 3 cases (one-sided sign tests, P Penstemon species evidently do hybridize naturally, and for nearly all characters the hybrids are consistent with the view that the parents differ largely by additive genetic effects.     

North American types of Oxytropis DC. (Leguminosae) at The Natural History Museum and Royal Botanic Garden, England, with nomenclatural comments and a new variety

Specimens of Oxytropis in the herbaria of The Natural History Museum and Royal Botanic Garden were examined to interpret their role in nomenclature. This is the first attempt at a systematic overview of specimens so important in understanding the genus as it occurs in North America. The review of specimens at BM and K during the present research has resulted in realignment of names of some of the taxa. Oxytropis campestris var. gracils (A. Nelson) Barneby is recognized herein as being predated by O. campestris var. spicata Hook., O. sericea var. spicata (Hook.) Barneby is replaced by O. sericea var. speciosa (Torr. & A. Gray) Welsh comb. nov., and O. campestris var. terrae-novae (Fern.) Barneby is superseded by O. campestris var. minor (Hook.) Welsh comb. nov. One new taxon is proposed: Oxytropis deflexa (Pall.) DC. var. pulcherrima Welsh & A. Huber, var. nov. Lectotypes are designated for the following taxa: Astragalus retroflexus Pall. Oxytropis artica R. Br., O. artica var. α subumbellata Hook., O. arctica var. β uniflora Hook. O. campestris var. β sepciosa Torr & A. Gray, O. campestris var. ξ melanocephala Hook., O. campestris var. δ spincata Hook., O. multiceps var. minor A. Gray, O. splendens Douglas ex Hook., O. splendens β richardsonii Hook., O. uralensis β subsucculenta Hook., and O. uralensis γ minor Hook.     

A new status for Penstemon cyananthus Hook. ssp. subglaber Pennell (Scrophulariaceae)

Penstemon cyanathus Hook. ssp. subglaber Pennell, a plant found frequently in northwestern Utah, southeastern Idaho, and southeastern Wyoming, is elevated to species status. A new name, Penstemon holmgrenii Clark is proposed because P. subglaber is preoccupied.
