On the typification of Oxytropis borealis DC.

The status of the name Oxytropis borealis DC. is reviewed as it applies to North American plants. A summary of the infraspecific taxa is presented, and several nomenclatural combinations are proposed: Oxytropis borealis DC. var. hudsonica (Greene) Welsh; O. borealis var. sulphurea (Pors.)

Field study of plant survival as affected by amendments to bentonite spoil

Efforts to reclaim amended and raw bentonite spoils with six plant species (two forbs, three shrubs, and one tree) were evaluated over a 4-year period. Plant species included fourwing saltbush ( Atriplex canescens [Pursh] Nutt.), big sagebrush ( Artemisia tridentata tridentata Nutt.), Rocky Mountain Juniper ( Juniperus scopulorum Sarg.), Russian olive ( Elaeagnus angustifolia L.) common yarrow ( Achillea millifolium L.) and scarlet globemallow ( Sphaeralcea coccinea [Pursh] Rydb.). Spoil treatments included addition of gypsum, sawdust, perlite, straw, and vermiculite; the control treatment was amended. Fourwing saltbush had 52% survival across all spoil treatments, with greatest survival occurring on perlite-treated spoil (80%), followed by gypsum (70%) and vermiculite amendments (70%). Survival of other plant species ranged from 0 to 2% averaged across all treatments after 4 years. No differences in plant survival occurred among amendments when all species were considered.     

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.

The taxa centering around Phlox austromontana Coville are revised. Named as a new variety is P. austromontana var. lutescens Welsh from eastern Garfield County, Utah. A new combination is provided as P. austromontana var.  jonesii (Wherry) Welsh.          

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.
