Uromyces intricatus is broken into six varieties. Var. umbellati and var. major attack montane and lowland species of Eriogonum subgen. Eueriogonum in much of western North America, and the former probably attacks Oxytheca. Vars. intricatus (Oregon, California), parvifolii (California), nivei (interior British Columbia to Arizona), and pluriporosus (mainly Montana, Wyoming, and Colorado) attack various species or species groups in Eriogonum subgen. Oregonium, the variation being partly geographic and partly due to host specialization. Var. intricatus attacks Chorizanthe spp. and Eriogonum subgen. Ganysma in California. This variety has met and intergraded with var. pluriporosus in the past but the link is now broken. Uromyces bisbyi, a microcyclic derivative of var. parvifolii, is described on Eriogonum parvifolium in California. The implications on the evolution of Eriogonum and the problem of realistic nomenclature of rusts derived from both host and geographic isolation are discussed. A table clarifies the nomenclature of reported host plants.

AbstractThe genus Japewia Tønsb. is introduced to accommodate three species including J. subaurifera Muhr & Tønsb. sp. nov. based on material from Norway, Sweden, Finland, Scotland, Canada (British Columbia) and U.S.A. (Washington). This species is closely related to Lecidea tornoensis Nyl. but is distinguished in being sorediate and by the production of lobaric acid (accessory) and acetone-soluble pigments. It grows on bark of deciduous and coniferous trees. Lecidea carrollii Coppins & P. James and L. tornoensis Nyl. are transferred to Japewia.

Terrane Accretion

Sinemurian phosphorites in southeastern British Columbia and southwestern Alberta conform with the "West Coast type" phosphorite depositional model. The model indicates that they were deposited on or near the Early Jurassic western cratonic margin, next to a sea or trough from which cold water upwelled. This suggests that the allochthonous terrane Quesnellia lay well offshore in Sinemurian time. The sea separating Quesnellia from North America was partly floored by oceanic crust ("Eastern Terrane") and partly by a thick sequence of rifted, continental terrace wedge rocks comprising the Purcell Supergroup and overlying Paleozoic sequence. This sequence must have been depressed sufficiently that access of upwelling deep currents to the phosphorite depositional area was not impeded.

Earthquakes in the past few thousand years have left signs of land-level change, tsunamis, and shaking along the Pacific coast at the Cascadia subduction zone. Sudden lowering of land accounts for many of the buried marsh and forest soils at estuaries between southern British Columbia and northern California. Sand layers on some of these soils imply that tsunamis were triggered by some of the events that lowered the land. Liquefaction features show that inland shaking accompanied sudden coastal subsidence at the Washington-Oregon border about 300 years ago. The combined evidence for subsidence, tsunamis, and shaking shows that earthquakes of magnitude 8 or larger have occurred on the boundary between the overriding North America plate and the downgoing Juan de Fuca and Gorda plates. Intervals between the earthquakes are poorly known because of uncertainties about the number and ages of the earthquakes. Current estimates for individual intervals at specific coastal sites range from a few centuries to about one thousand years.

The millipede genus Amplaria Chamberlin, 1941 (senior synonym of Vaferaria Causey, 1958 and Speostriaria Causey, 1960) is endemic to western North America, from Mt. Palomar and San Luis Obispo, California, north to southwestern British Columbia, Canada, and east to northern Idaho. Seven species names are currently assigned to the genus. Below I describe ten additional new species: Amplaria crawfordi, Amplaria fontinalis, Amplaria rykkenae, Amplaria arcata, Amplaria baughi, Amplaria staceyi, Amplaria umatilla, Amplaria cervus, Amplaria mendocino and Amplaria flucticulus, and provide new records of Amplaria nazinta Chamberlin.

Okanagan Highlands

We survey the known avian fossils from Ypresian (early Eocene) fossil sites of the North American Okanagan Highlands, mainly in British Columbia (Canada). All specimens represent taxa that were previously unknown from the Eocene of far-western North America. Wings from the McAbee site are tentatively referred to the Gaviiformes and would constitute the earliest fossil record of this group of birds. A postcranial skeleton from Driftwood Canyon is tentatively assigned to the Songziidae, a taxon originally established for fossils from the Ypresian of China. Two skeletons from Driftwood Canyon and the McAbee site are tentatively referred to Coliiformes and Zygodactylidae, respectively, whereas three further fossils from McAbee, Blakeburn, and Republic (Washington, USA) are too poorly preserved for even a tentative assignment. The specimens from the Okanagan Highlands inhabited relatively high paleoaltitudes with microthermal climates (except Quilchena: lower mesothermal) and mild winters, whereas most other Ypresian fossil birds are from much warmer lowland paleoenvironments with upper mesothermal to megathermal climates. The putative occurrence of a gaviiform bird is particularly noteworthy because diving birds are unknown from other lacustrine Ypresian fossil sites of the Northern Hemisphere. The bones of the putative zygodactylid show a sulphurous colouration, and we hypothesize that this highly unusual preservation may be due to the metabolic activity of sulphide-oxidizing bacteria.

The genus Cryptantha Lehm ex G. Don section Oreocarya (E. Greene) Payson of the family Boraginaceae presents some problems to botanists, both professional and amateur, in the keying and identification of species. The genus contains approximately 150 species, the section about 60 perennial and biennial herbs located generally in western North America. Identification has presented some taxonomic difficulty due to the variability and lack of distinctive vegetative characters. Botanists have turned to the nutlet (fruit) and flower morphology to aid in identification for precise specific differentiation. In the past, 10X magnification and a decent botanical illustrator were required to provide the illustrations necessary to assist in this identification. We are in the process of collecting micrographs of nutlets (dorsal, sagital, and ventral views) and developing a webpage containing these micrographs along with descriptions of their morphological variations.

The discovery of a new locality yielding giant Guadalupian (Lower Permian) fusulinids in east-central Alaska extends the range of these forms much farther north than previously known, and into a tectonostratigraphic terrane from which they previously had not been reported. The number of areas from which giant parafusulinids are known in North America is thus raised to eight. Three of these localities are in rocks that previously had been referred to the allochthonous McCloud belt arc, and one, West Texas, is known to have been part of Paleozoic North America. Comparison of species from all areas suggests that there are two closely related species groups: one represented in Texas and Coahuila, and the other represented in Sonora, northern California, northeastern Washington, southern and northern British Columbia, Alaska, and apparently in Texas. These groups may differ because they are of slightly different ages or because interchange between the faunas of Texas–Coahuila area and the other regions was somewhat inhibited during the Early Permian.

The Relationship

Baeomyia n.g. is described for a group of small (2–3 mm long) tachinids belonging to the Siphona group of the Siphonini. All known specimens were collected in western North America, with two species recorded from southern British Columbia (Baeomyia xanthogaster n. sp. and Baeomyia juniperi n. sp.) and three species recorded from desert localities in the American Southwest (type-species Baeomyia hurdi (Reinhard), Baeomyia antennata n. sp. and Baeomyia sonorensis n. sp.). Keys to adult males and females are provided for separation of species. Systematics of the Siphonini and Siphona group are reviewed, including a discussion of the synapomorphies upon which each is defined. Baeomyia species are inferred to form a monophyletic taxon within the Siphona group on the basis of five synapomorphies, though the relationship between the genus and other Siphona group taxa is unresolved. The apparent disjunction of Baeomyia species into northern and southern ranges may be the result of relatively recent speciation events, because differences among species are slight. A detailed zoogeographic analysis of the distribution pattern must await further phylogenetic data.
