A Site

Blakely's manuscript name Eucalyptus "rivalis" was applied to a specimen taken from a site about 30 miles south-west of Perth, W.A., where at least two trees apparently identical with the original specimen are growing at the boundary of areas occupied by E. marginata and E. megacarpa. On the basis of conditions of occurrence, morphology, and a progeny test it is considered that E. "rivalis" is a hybrid between E. marginata and E. megacarpa. There is morphological evidence that E. megacarpa and the related E. preissiana have more characters in common with the Renantherae than with any other section in the genus and that these species were incorrectly placed by Blakely in the Macrantherae, an error resulting from the use of a single character, anther shape, in determining affinity. From evidence of morphology and occurrence it is considered that E. kalganensis and E. chrysantha probably represent hybrids of E. preissiana with the renantherous species E. marginata and E. sepulcralis respectively, providing cases parallel with E. "rivalis".

A New Species

A new species of Cymbidium (Orchidaceae), Cymbidium xichouense, from Yunnan Province, China, is described and illustrated based on morphological evidence and molecular analyses. The new orchid is morphologically similar to C. qinbeiense, but it has several morphological features that distinguish it from C. qiubeinense and all other recognized species in Cymbidium. Phylogenetic analyses based on nuclear (ITS) and plastid DNA (matK) were conducted, and the results also supported the status of C. xichouense as a new species, which is sister to C. qiubeiense.

South West Coast

In the ten years between 1929 and 1939 three remarkable books were produced in a tiny Irish-speaking community of less than one hundred and fifty people living on the Great Blasket, an island off the south-west coast of Kerry. The authors, two men and a woman, were peasants, eking out a scanty living by farming and fishing. They were technically literate in that they had acquired the rudiments of reading and writing at the island school, but for all practical purposes their culture was oral. They certainly had neither opportunity nor inclination for book-reading. Yet out of the resources of their oral culture they produced works of a high literary standard, one of which has (in translation) achieved the status of a ‘World's Classic’.

Geographic Setting

The occurrence of Saurolophus from the Moreno Formation (late Maastrichtian) of California is investigated and an incomplete, poorly preserved, skull (LACM/CIT 2852) is described. The skull lacks the braincase (including the frontals) and much of the nasals, and the preserved portions are crushed or plastically deformed, which makes anatomical interpretations difficult. A preserved midline fragment of the conjoined nasals suggests that it lacked a gryposaur-like “Roman nose”, but the nature of the crest, if present, is impossible to determine with certainty. A phylogenetic analysis places this specimen as either the sister taxon of Saurolophus or as the sister taxon to a clade comprising Edmontosaurus and Anatotitan . There is no compelling morphological evidence to support the previous assignment of LACM/CIT 2852 to Saurolophus rather than to Edmontosaurus, and its poor preservation prevents positive assignment to any taxon below Hadrosaurinae indet. Given its geographic setting and morphological uncertainties, it is also possible that this specimen represents a separate taxon, but more material is needed to clarify the identity of the Moreno hadrosaurine. LACM/CIT 2852 does, however, provide evidence that Maastrichtian hadrosaurines ranged west of the Sierra Nevada magmatic arc, in an area where dinosaur diversity is poorly known.

The Status

Mail surveys were sent to field staff of the Agriculture Protection Board of Western Australia to assess the distribution and status of four species of parrot in the agricultural region of south-west Western Australia in 1970, 1980 and 1990. The surveys indicated that the populations of the Regent Parrot (Polytelis anthopeplus) and the Western Rosella (Platycercus icterotis) have declined in range considerably since 1970. The populations of the Red-capped Parrot (Purpureicephalus spurius) and the Port Lincoln Ringneck (Barnardius zonarius) have suffered little or not at all during the same period. Factors which appear to have contributed to the observed changes in distribution and status include clearing for agriculture, dietary preferences, physiology, habitat requirements, altered fire regimes, grazing by exotic herbivores and reduced winter rainfall. These surveys have shown that species which were formerly considered common and widespread have declined with little comment having been made of these changes. The implications of this are serious, both for these formerly common species and for rarer bird species which have similar ecological requirements. The technique of mail surveys has considerable merit for quickly assessing the status of some species of birds, but will be limited by the expertise of the respondents and the degree to which the species in question can be observed.

The Relationship

This article offers the argument that suffering (yisurin) in the Babylonian Talmud functions as a locus for the relationship between God and rabbinic Jews. Scholars of rabbinic martyrdom and asceticism have tended to claim that the Talmud's positive portrayal of suffering is a theodical apology for unexplained evil in the world. However, the article argues that the Talmud—in contrast to earlier rabbinic texts—presents suffering as spiritually relevant not primarily to justify preexisting suffering, but rather to develop a site at which to interpret information about an individual's spiritual status. The article draws on theories of sacrifice's structure and function, in conjunction with close analysis of rabbinic texts that relate suffering to sacrifice. The pericope at the core of the article's argument demonstrates a strikingly technical approach to the human experience of suffering, describing four examples of yisurin in which no real physical suffering occurs; in each instance the “victim” experiences extremely mild discomfort at most, and at the least barely registers an experience of inconvenience. Nonetheless, these experiences all qualify as “suffering,” and are thus still understood to bear indisputable soteriological import. Physical suffering in the Talmud is thus open for interpretation, yielding information about the status of the sufferer's spiritual self. Human suffering is viewed as religiously desirable in both late rabbinic and early Christian literatures. By developing an understanding of its hermeneutical function for the rabbis, this article helps to elucidate the value of suffering for rabbinic literature as a subset of late antique religious discourse.

ABSTRACTA magnetometry survey of the Roman fort at Lake Farm, near Wimborne Minster in Dorset, first discovered in 1959, has upgraded the status of this site to a full legionary fortress: a major base of the legio II Augusta during the subjugation of the Durotriges and other tribes of south-west Britain. The interior layout of the fortress was identified for the first time, together with the original road and river connections, extensive areas of extramural activity and evidence for an earlier phase of the site as a marching camp.

This study compares, for the first time, variation in estimates of susceptibility of native flora to Phytophthora cinnamomi Rands among four databases and proposes an estimate of the proportion of the flora of the South-West Botanical Province of Western Australia that is susceptible to the pathogen. Estimates of the susceptibility of south-western native flora to P. cinnamomi infection were obtained from databases for Banksia woodland of the Swan Coastal Plain, jarrah (Eucalyptus marginata Donn. ex Smith) forest, the Stirling Range National Park and Rare and Threatened Flora of Western Australia. For the woodland, forest and national park databases, hosts were naturally infected in uncontrolled diverse natural environments. In contrast, threatened flora were artificially inoculated in a shadehouse environment. Considerable variation occurred within taxonomic units, making occurrence within family and genus poor predictors of species susceptibility. Identification of intra-specific resistance suggests that P. cinnamomi could be having a strong selection pressure on some threatened flora at infested sites and the populations could shift to more resistant types. Similar estimates of the proportion of species susceptible to P. cinnamomi among the databases from the wide range of environments suggests that a realistic estimate of species susceptibility to P. cinnamomi infection in the south-western region has been obtained. The mean of 40% susceptible and 14% highly susceptible equates to 2284 and 800 species of the 5710 described plant species in the South-West Botanical Province susceptible and highly susceptible to P. cinnamomi, respectively. Such estimates are important for determining the cost of disease to conservation values and for prioritising disease importance and research priorities. P. cinnamomi in south-western Australia is an unparalleled example of an introduced pathogen with a wide host range causing immense irreversible damage to unique, diverse but mainly susceptible plant communities.

A number of samples of subfossil Cepaea nemoralis and hortensis from sites in southern Britain of archaeological interest, ranging in date from about 4500 b .c . to Romano-British and Anglo-Saxon, have been scored for frequency of the major banding morphs, and compared with present-day samples taken on each site or as near to it as these species could be found. In C. nemoralis there is a significant decrease of unbandeds from pre-iron Age samples to the corresponding ones for the present day, but no indication of systematic change from Iron Age samples to the present day. Spread banded also shows changes from pre-iron Age samples to present-day ones, but very little change from the early Iron Age to the present day. The smaller samples of C. hortensis available give no sign of a trend although there is much change from pre-iron Age times to the present; Iron Age samples and the corresponding present-day ones do not show the relative constancy of composition seen in C. nemoralis —as usual these two very closely related species are behaving differently. At the present day there is evidence (experimental and distributional) that the frequencies of banding morphs of C. nemoralis are affected by climate, unbandeds and mid-bandeds being favoured by better summers than those normal in Britain at present. The available evidence, from pollen analysis and other sources, of changes in the climate of southern Britain in the last 6500 years suggests that the observed differences in morph frequencies can be related to known climatic changes, in agreement with present-day evidence. One area effect (south-west M arlborough Downs) has contracted and become less intense since pre-iron Age times, as perhaps have others; in some cases a site has remained in an area effect, but the effect itself has changed. Two pairs of samples from lowland sites appear to have changed from frequencies indicating area effects in pre-iron Age times to others consistent with visual selection at the present day. Area effects seem to have been rather constant from the Iron Age to the present day.
