From the Publisher: San Bruno Mountain, located in the center of the San Francisco Bay Area, is a four-squaremileglobal treasure—a natural preserve touted by biologist E. O. Wilson as one of the world’s rare biodiversityhot spots. Bathed in fog and wind and preserved from destruction by the fierce work of localconservationists, this mountain offers visitors a glimpse of what San Francisco looked like before colonization.Drawing on years of visits, observations, and research to offer a comprehensive flora of San BrunoMountain and its endangered species, conservationists Doug Allshouse and David L. Nelson help us understandthis unique and precious place from the point of view of the plants in this one-of-a-kind field guide.Detailing a total of 528 plant species (among them 316 natives), the authors also delve into the history of thisliving, changing habitat at the southern edge of San Francisco. The birds, butterflies, reptiles, geology, climate,dynamic changes, and political history of the preserve also feature in San Bruno Mountain. Even locals whohave enjoyed hiking and viewing the mountain for years will be astonished at this book’s revelations about thediversity and importance of this wild place.
圣布鲁诺山,位于旧金山湾区的中心,是一个四平方英里的全球宝藏,是一个自然保护区,被生物学家e.o.威尔逊吹捧为世界上罕见的生物多样性热点之一。这座山沐浴在雾和风中,在当地自然资源保护主义者的努力下免受破坏,游客们可以一窥旧金山被殖民前的样子。通过多年的访问、观察和研究,为圣布鲁诺山及其濒危物种提供了一个全面的植物群,环保主义者Doug allhouse和David L. Nelson在这本独一无二的野外指南中帮助我们从植物的角度了解这个独特而珍贵的地方。详细介绍了总共528种植物物种(其中316种是本地植物),作者还深入研究了这种生物的历史,改变了旧金山南部边缘的栖息地。鸟类、蝴蝶、爬行动物、地质、气候、动态变化和保护区的政治历史也是圣布鲁诺山的特色。即使是那些多年来一直喜欢徒步旅行和观赏这座山的当地人,也会对这本书所揭示的这片荒野的多样性和重要性感到惊讶。

Eleven angiosperm plant species are added to the flora of New Mexico that were revealed through herbarium curation associated with a project to digitize and unify the two herbaria of New Mexico State University (NMC & NMCR) and through ongoing field work. One, Dimorphocarpa candicans, is restored to the state’s flora, after it was earlier placed into synonymy with D. wislizeni, a close but morphologically distinct relative. The current IUCN Redlist conservation status of endangered (EN) for Gossypium thurberi should be revisited given its newly discovered range extension into southwestern New Mexico. New county-level distribution records are provided for a total of 16 taxa. Crepis tectorum, one of the species added to the flora of New Mexico, is likewise documented for Colorado, where it occurs in three counties. All of the plants added to the floras pertain to species that are either native or introduced with the potential to spread and become naturalized in the landscape. A putative introgressive population is also reported for New Mexico between Quercus turbinella and Q. laceyi, the latter otherwise unknown in the state. For all new records, full citations of specimen vouchers are provided to document the extended distributional ranges.

Vegetational changes over a 6-year period (2012 to 2017) were recorded in upland pine – hardwood forests on Cook’s Branch Conservancy (CBC) in Montgomery County, Texas, using permanent vegetation monitoring plots as a basis for following future vegetational changes. Cook’s Branch Conservancy is a 2,160-hectare preserve purchased by George and Cynthia Mitchell in 1964 and is now part of a conservation program operated by the Cynthia and George Mitchell Foundation. Plots sampled for this study include eight Fire Monitoring Handbook vegetation plots located in upland forests over sandy soils including four plots located in frequently burned stands (11 times since 2002) and four plots located in stands that have not been burned in decades (20+ years). Data collected confirm significant changes to vegetational structure in frequently burned forests compared to similar habitats that are unburned. Prior to initiation of prescribed burning in 2001, habitat conditions and species composition was similar in stands surrounding all eight plots sampled. The overstory tree structure of all eight plots sampled is similar in basal area, canopy cover, and in species composition. The number of midstory trees is less in frequently burned plots, however, frequently burned plots possess a much greater number of seedlings. At the shrub level, Callicarpa americana and Ilex vomitoria represented 97.7% of total stems in the frequently burned plots, with Callicarpa americana stems count increasing in frequently burned plots, suggesting the species is pyrophytic. Additionally, diversity of herbaceous species was higher in frequently burned plots vs unburned plots. Visually, the frequently burned forest is open in the understory, while the unburned forest is dense with woody understory vegetation making it difficult to traverse on foot.

An agamic complex of 20- and 10-stamen, black-fruited hawthorns (Crataegus subg. Sanguineae, sect. Douglasianae) occurs in western North America, with a 10-stamen taxon disjunct in the upper Great Lakes basin. Here, we recircumscribe the 20-stamen taxa at the core of this complex (C. ser. Douglasianae). This is needed in order to distinguish between a presumptively ancestral diploid and its allo- and autopolyploid derivatives, all differing in breeding system, distribution, morphology, and pattern of genetic variation. The earliest name for these 20-stamen taxa, Crataegus gaylussacia A. Heller, was given to distinctive plants of Marin and Sonoma counties in California that have recently been shown to be autotriploids. In Flora North America, however, this name was applied to all 20-stamen, black-fruited hawthorns. We recircumscribe C. gaylussacia, and also recircumscribe and typify a slightly younger name, C. suksdorfii (Sarg.) Kruschke, with a specimen from southern Washington with the diminished pollen fertility found in allopolyploid, apomictic black-fruited hawthorns occurring east of the Cascades, from northern California north to southernmost Alaska. Finally, we recognize the diploid, self-incompatible, sexual black-fruited hawthorns found west of the Cascades from northern California to southwestern Washington as Crataegus rhodamae-loveae sp. nov. Together with the 10-stamen, black-fruited hawthorns in predominantly tetraploid, apomictic, and self-fertile C. douglasii Lindl. and its segregates (discussed in detail in a companion paper), these species are linked by whole genome duplications associated in most cases with hybridization, with members of red-fruited C. subg. Americanae, and with each other. We suggest that this complex provides a model for understanding other such groups of Crataegus species that are related by whole genome duplications resulting from the fertilization of unreduced gametes (facilitated by but not necessarily dependent on occurrence of gametophytic apomixis), often together with hybridization. We note that an earlier effort at DNA barcoding these and other hawthorn species that provided limited support for our taxonomic decisions here also demonstrated some limited utility of the original plant DNA barcoding loci in groups like Crataegus. The taxonomic decisions we advocate will warrant consideration when other groups of hawthorns are revised in the light of data like those employed here.

A new species of Oreocarya (Boraginaceae), O. worthingtonii Sivinski, is described from the Brokeoff Mountains branch of the Guadalupe Mountain range in Eddy and Otero counties, New Mexico. It is similar to Oreocarya oblata (M.E. Jones) J.F. Macbr. in pubescence, homostyly and globular, roughened fruits, but differs in its slender stems with linear leaves, subcapitate inflorescence and finely tuberculate nutlets. Specimen photos and a key to Oreocarya species with globular fruits and roughened nutlets from the northern Chihuahuan Desert are also presented.
