Alplains 2013 Seed Catalog P.O
ALPLAINS 2013 SEED CATALOG P.O. BOX 489, KIOWA, CO 80117-0489, U.S.A. Three ways to contact us: FAX: (303) 621-2864 (24 HRS.) email: [email protected] website: www.alplains.com Dear Growing Friends: Welcome to our 23rd annual seed catalog! The summer of 2012 was long, hot and brutal, with drought afflicting most of the U.S. Most of my botanical explorations were restricted to Idaho, Wash- ington, Oregon and northern California but even there moisture was below average. In a year like this, seeps, swales, springs, vestigial snowbanks and localized rainstorms became much more important in my search for seeding plants. On the Snake River Plains of southern Idaho and the scab- lands of eastern Washington, early bloomers such as Viola beckwithii, V. trinervata, Ranunculus glaberrimus, Ranunculus andersonii, Fritillaria pudica and Primula cusickiana put on quite a show in mid-April but many populations could not set seed. In northern Idaho, Erythronium idahoense flowered extensively, whole meadows were covered with thousands of the creamy, pendant blossoms. One of my most satisfying finds in the Hells Canyon area had to be Sedum valens. The tiny glaucous rosettes, surround- ed by a ring of red leaves, are a succulent connoisseur’s dream. Higher up, the brilliant blue spikes of Synthyris missurica punctuated the canyon walls. In southern Oregon, the brilliant red spikes of Pedicularis densiflora lit up the Siskiyou forest floor. Further north in Oregon, large populations of Erythronium elegans, Erythronium oregonum ssp. leucandrum, Erythro- nium revolutum, trilliums and sedums provided wonderful picture-taking opportunities. Eriogonum species did well despite the drought, many of them true xerics. -

Gymnaconitum, a New Genus of Ranunculaceae Endemic to the Qinghai-Tibetan Plateau
TAXON 62 (4) • August 2013: 713–722 Wang & al. • Gymnaconitum, a new genus of Ranunculaceae Gymnaconitum, a new genus of Ranunculaceae endemic to the Qinghai-Tibetan Plateau Wei Wang,1 Yang Liu,2 Sheng-Xiang Yu,1 Tian-Gang Gao1 & Zhi-Duan Chen1 1 State Key Laboratory of Systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, P.R. China 2 Department of Ecology and Evolutionary Biology, University of Connecticut, Storrs, Connecticut 06269-3043, U.S.A. Author for correspondence: Wei Wang, [email protected] Abstract The monophyly of traditional Aconitum remains unresolved, owing to the controversial systematic position and taxonomic treatment of the monotypic, Qinghai-Tibetan Plateau endemic A. subg. Gymnaconitum. In this study, we analyzed two datasets using maximum likelihood and Bayesian inference methods: (1) two markers (ITS, trnL-F) of 285 Delphinieae species, and (2) six markers (ITS, trnL-F, trnH-psbA, trnK-matK, trnS-trnG, rbcL) of 32 Delphinieae species. All our analyses show that traditional Aconitum is not monophyletic and that subgenus Gymnaconitum and a broadly defined Delphinium form a clade. The SOWH tests also reject the inclusion of subgenus Gymnaconitum in traditional Aconitum. Subgenus Gymnaconitum markedly differs from other species of Aconitum and other genera of tribe Delphinieae in many non-molecular characters. By integrating lines of evidence from molecular phylogeny, divergence times, morphology, and karyology, we raise the mono- typic A. subg. Gymnaconitum to generic status. Keywords Aconitum; Delphinieae; Gymnaconitum; monophyly; phylogeny; Qinghai-Tibetan Plateau; Ranunculaceae; SOWH test Supplementary Material The Electronic Supplement (Figs.

We appreciate their input and comments, which resulted in a more robust status assessment and final report. Suggested reference: U.S. Fish and Wildlife Service. 2020. Species status assessment report for the San Clemente Island larkspur (Delphinium variegatum ssp. kinkiense), Version 1.0. March 2020. Sacramento, CA. SSA Report – San Clemente Island larkspur ii March 2020 EXECUTIVE SUMMARY This Species Status Assessment (SSA) provides an analysis of the overall species viability for the San Clemente Island larkspur (Delphinium variegatum ssp. kinkiense). To assess the viability of this subspecies, we, the U.S. Fish and Wildlife Service, used the conservation biology principles of resiliency, redundancy, and representation (3 Rs). Specifically, we identified the subspecies’ ecological requirements and resources needed for individual survival and reproduction. We described the stressors (threats) influencing these resources and evaluated current levels of population resiliency and subspecies redundancy and representation using available metrics to forecast the ability of this subspecies to sustain populations into the future. -

Genetic Diversity in Delphinium Variegatum (Ranunculaceae): a Comparison of Two Insular Endemic Subspecies and Their Widespread Mainland Relative1
American Journal of Botany 89(4): 613–622. 2002. GENETIC DIVERSITY IN DELPHINIUM VARIEGATUM (RANUNCULACEAE): A COMPARISON OF TWO INSULAR ENDEMIC SUBSPECIES AND THEIR WIDESPREAD MAINLAND RELATIVE1 SHANA C. DODD2,4 AND KAIUS HELENURM3,5 2Department of Biology, San Diego State University, San Diego, California 92182 USA; and 3Department of Biology, University of South Dakota, Vermillion, South Dakota 57069 USA Delphinium variegatum is subdivided into three subspecies: D. v. variegatum is widespread in central and northern California, while D. v. kinkiense (an endangered taxon) and D. v. thornei are endemic to San Clemente Island off the coast of southern California. Electrophoretic data for 19 loci were collected from 7 populations of the mainland subspecies and all 24 known populations of the two insular endemic subspecies. Populations of the widespread mainland subspecies have more polymorphic loci (33.6% vs. 24.5%) and more alleles per polymorphic locus (2.61 vs. 2.15) than the insular endemic subspecies. However, observed heterozygosities are lower in the mainland subspecies (0.041 vs. 0.071), presumably due to lower levels of outcrossing (t ϭ 0.464 vs. 0.895). Expected heterozygosities are similar (0.064 vs. 0.074) due to lower alternative allele frequencies in populations of the mainland subspecies (mean q ϭ 0.075 vs. 0.190). Populations of the two insular subspecies are almost equivalent genetically (mean I ϭ 0.997) regardless of taxonomic designation or geographic location. In contrast, one of the mainland populations is genetically well differentiated from the others. If this exceptional population is excluded, the mainland subspecies partitions genetic diversity similarly to the island subspecies, with most variation being found within populations (GST ϭ 0.073 vs. -
INTRODUCTION This Check List of the Plants of New Jersey Has Been
INTRODUCTION This Check List of the Plants of New Jersey has been compiled by updating and integrating the catalogs prepared by such authors as Nathaniel Lord Britton (1881 and 1889), Witmer Stone (1911), and Norman Taylor (1915) with such other sources as recently-published local lists, field trip reports of the Torrey Botanical Society and the Philadelphia Botanical Club, the New Jersey Natural Heritage Program’s list of threatened and endangered plants, personal observations in the field and the herbarium, and observations by other competent field botanists. The Check List includes 2,758 species, a botanical diversity that is rather unexpected in a small state like New Jersey. Of these, 1,944 are plants that are (or were) native to the state - still a large number, and one that reflects New Jersey's habitat diversity. The balance are plants that have been introduced from other countries or from other parts of North America. The list could be lengthened by hundreds of species by including non-persistent garden escapes and obscure waifs and ballast plants, many of which have not been seen in New Jersey since the nineteenth century, but it would be misleading to do so. The Check List should include all the plants that are truly native to New Jersey, plus all the introduced species that are naturalized here or for which there are relatively recent records, as well as many introduced plants of very limited occurrence. But no claims are made for the absolute perfection of the list. Plant nomenclature is constantly being revised. Single old species may be split into several new species, or multiple old species may be combined into one.
