Coppice-with-standards stands were clear-felled during the Second World War and replanted with conifer/conifer-broadleaved mixtures in which the conifer was dominant. Since 1985 broadleaves have been favoured. In 1983, the ground flora had been recorded in six plantation stands of different tree species and compared with three remnant broadleaved stands. Five 200 m2 quadrats were taken spread across each stand. The survey was repeated using the same methods in 2015 to assess changes. In addition, in 2015, single 200 m2 quadrats were taken in 21 other stands to put the re-recorded stands into a wider site context. In the nine re-recorded stands, six stands lost species (mean number of species per quadrat) between 1983 and 2015, only three stands gained them. Increases in species richness were associated with management (felling or thinning) or where stands had opened out through wind-throw. Species with higher Ellenberg light scores showed higher turnover than more shade-tolerant species. In stands recorded only in 2015 oak Quercus robur stands derived from formerly conifer-dominant crops, showed a similar richness and species profile to the remnant broadleaved stands. Specialist woodland plants did not appear to be adversely affected by this active management of the stands. The results indicate that in terms of the ground flora at this site the 1985 Broadleaves Policy achieved one of its aims of maintaining/restoring the special character of ancient woodland.","PeriodicalId":19229,"journal":{"name":"New Journal of Botany","volume":"144 1","pages":"125 - 135"},"PeriodicalIF":0.0,"publicationDate":"2017-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89677477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is very little modern information about these species and as they have not been listed under any of the currently accepted sections of the genus they are at risk of being completely forgotten. They have always been considered as intermediate between H. sect. Alpina and sect. Prenanthoidea, but as discussed here they can hardly be included in either of these sections. However, C European species intermediate between the same two sections have been referred to H. sect. Pulmonarioidea and it appears appropriate to include the Depilata here as well. Hereby, the geographic range of H. sect. Pulmonarioidea is most significantly enlarged and its morphological circumscription is somewhat amended. The morphology of Scandinavian H. sect. Pulmonarioidea is described and a brief overview of the species and their distribution is provided. In addition, the possibility that the species concerned may have evolved in situ in Scandinavia through hybridisation between members of H. sect. Alpina and sect. Prenanthoidea is discussed.","PeriodicalId":19229,"journal":{"name":"New Journal of Botany","volume":"218 1","pages":"147 - 151"},"PeriodicalIF":0.0,"publicationDate":"2017-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74394186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bateman & Tattersall. This vigorous plant was found and digitally imaged on a roadside verge of Crousa Downs on the Lizard Peninsula of Cornwall by Barry Tattersall in June, 2016, and tentatively identified as a hybrid new to science. However, detailed morphometric analysis using 40 characters and based partly on the initial images failed to confirm its hybrid origin, suggesting instead that it was a slightly deviant plant of D. praetermissa. Comparison of the hybrid with its putative parents by DNA sequencing of nuclear (ITS) and plastid (trnL-F) regions later confirmed the F1 hybrid nature of the plant, as well as identifying D. praetermissa as the hybrid’s ovule-parent and G. borealis as its pollen-parent. This result contrasted with prevailing theory that pollinators (in this case, most likely bumblebees) should preferentially transfer pollinaria from the shorter-spurred plant to the longer-spurred plant. The Crousa Downs plant is thus best described as a cryptic hybrid that shows strong maternal dominance in inheritance patterns, perhaps reflecting the fact that its ovule-parent is allotetraploid but its pollen-parent is diploid. A brief review of × Dactylodenia hybrids in the British Isles concludes that opportunities for the origin of this particular hybrid are severely limited by the contrasting habitat preferences and geographic distributions of its parents. An ongoing future for this apparently unique plant is unlikely due to local authorities’ inappropriately-timed mowing regimes.","PeriodicalId":19229,"journal":{"name":"New Journal of Botany","volume":"9 1","pages":"64 - 77"},"PeriodicalIF":0.0,"publicationDate":"2017-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79144023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At least two species are considered to be native to North America: Wing-leaf Soapberry S. saponaria L. and Florida Soapberry S. marginatus Willdenow. However, some authors consider that both of these species are synonymous. S. saponaria has been widely distributed by man throughout tropical regions of Central and South America, including the Caribbean Islands, Africa, India, Asia and Australia. Some Sapindus diaspores (fruits and seeds) inevitably find their way into rivers and eventually float out to sea where they are dispersed by oceanic currents and a few occasionally reach NW European waters, most likely from the Caribbean region via the Gulf Stream and North Atlantic Drift. The current review collates all known records of Sapindus endocarps found stranded in UK waters, including one previously unpublished record. Although the identification of Sapindus endocarps currently defy efforts to pin them down to species level, at least one the UK specimens was considered to be S. saponaria. Morphometric studies of Sapindus endocarps, combined with confirmatory genetic analyses, may help to resolve both the identity and provenance of drift endocarps found stranded in maritime regions on both sides of the North Atlantic.","PeriodicalId":19229,"journal":{"name":"New Journal of Botany","volume":"1 1","pages":"160 - 164"},"PeriodicalIF":0.0,"publicationDate":"2017-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72721377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One hundred and thirty-seven quadrats alongside linear features that had all been recorded in the same place in 1990, 1998 and 2007 were re-found and the plant species compositions recorded. Changes in individual species frequency were analysed and the results summarised by a number of ecosystem services and one disservice whose delivery are linked to functionally important species being present. Results indicated a continuation of a trend towards increased shading and woody cover seen between the first Countryside Survey in 1978 and the last in 2007. Most species showed no significant change in frequency suggesting that the significant directional trend seems only to have impacted a subset of the species present. A greater sample size would be required to capture impacts on a larger number of species including a wider range of Common Standards Monitoring positive indicator species that may find refuge on the linear network in lowland Wales. Having grouped species by the ecosystem services they help deliver, we found that injurious weeds (an ecosystem disservice to food production) either declined or remained stable, a greater number of butterfly larval food plants decreased than increased and there was a net decline in potential nectar yield. Consistent with the successional trend, increasing species in these service-providing groups tended to be tall or shade-tolerant herbs and tree species. Decreasing species tended to be short, shade-intolerant forbs.","PeriodicalId":19229,"journal":{"name":"New Journal of Botany","volume":"12 1","pages":"112 - 124"},"PeriodicalIF":0.0,"publicationDate":"2017-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86829809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
