Some material is included in this issue. Tom Turner has contributed a different sort of article with a detailed look at one of his local sites, with a suggest - ed walking route. There may be interest in more of this type of article from other parts of the country, so do let me know if you like (or indeed don’t like) this approach. Several submitted contributions could not be accommodated in this issue but more will be published next time. Do keep sending in material as it is the essen - tial life blood for the journal! Chairman’s Note Celia Wright Greetings. I am writing this just after another successful Northern Meeting in Leeds. Once again, it was organised impeccably by Ken Kitchen (with Ann’s help). John and Shelagh Temporal will be stepping into this role, so my special thanks to Ken and Ann for all their help with HOS. I would like to take the opportunity to thank Andrew Wells and Lesley Goode for their excellent management of the HOS sound system. It was essential for the Steve Nicholls film “Orchids – Sex & Lies” which started the Leeds meeting in spectacular fashion. Our thanks to Steve for sharing it. If you have an innovative way of talking about hardy orchids, please get in touch with me as it could make a good meeting presentation in the future. The Leeds meeting included an Extraordinary General Meeting when the motion to increase subscription rates from May 2014 was passed unanimously. Included with this issue of JHOS is a letter from Moira Tarrant concerning the mechanism of the change, especially for those who pay by standing order. Please take note of what she says and change your standing order amount now so that everything will be ready for the correct payment next May. Our next meeting is at Kidlington on Sunday November 17 th . We have a good set of speakers lined up and I hope to see lots of people there. Don’t forget to get your dig - ital entries for the photographic competition in to Ann Kitchen ([email protected] ) by 14 th October. The closing date for print entries is 4 th November. Finally, Iain and I have changed our email addresses. The Committee contact details list inside the front cover of this issue of JHOS reflects this. From now on, to con - tact me, please use [email protected] and for Iain, use [email protected] . My best wishes to you all. 112 JOURNAL of the HARDY ORCHID SOCIETY Vol. 10 No. 4 (70) October 2013 The Pollination of European Orchids: Part 2: Cypripedium and Cephalanthera Jean Claessens & Jacques Kleynen Introduction In the first part of this series we discussed and illustrated the construction of an aver - age European orchid flower. Much of this applies to many European orchids. In this part we will show two orchid genera that deviate from the general pattern. Cypripedium calceolus , the Lady’s slipper orchid This orchid certainly is the orchid lover’s favourite with its brownish perianth and the beautifully contrasting yellow slipper. The Lady’s Slipper is a primitive orchid, the only European species that has two anthers. The pollen is not mealy, but instead the loose pollen grains are packed into a viscid fluid. The stigma is quite large, dry and covered with minute pointing papillae (Figure 1). The yellow slipper serves as a means of attraction from afar. The flower emits a scent, but colour is the key attrac - tion mechanism. The crimson spots on the white staminode and on the veins in the bottom of the lip (Figure 2) are false nectar guides (Nilsson 1981). C. calceolus is above all visited and pollinated by Andrena bees. Visitors generally land on the lip which has margins covered with an oily substance. They either fall into the pouch losing their balance or they fly into the flower searching for nectar. Once inside the bees find out there is no nectar and show a disturbed behaviour, making efforts to escape. They try to climb the inside of the pouch, but this is covered with a film of oil as well, preventing them from getting out. They also try to escape by climbing the slippery staminode, but always fall back into the flower. There are only two exits from the flower, two small orifices left and right of the column (Figure 3). Near the lip base are various translucent spots on both sides of the slipper. They help to guide the bees towards the exits. Fig. 1: Cypripedium calceolus , column showing the large, shield-like stigma. Behind it is the staminode; under the stigma are the two anthers with the pollen smear.

Blume f. conformis Hi- ros. Hayak. et J. Yokoy., which occurs in the vicinity of the Tsukuba mountain range in Ibaraki Prefec- ture, Japan. This peloric form is sympatric with C. falcata f. falcata. The peloric flowers have a petal-like lip. The flowers are radially symmetrical and the perianth parts spread weakly compared to normal flow- ers. The stigmas are positioned at the column apex, thus neighboring stigmas and the lower parts of the pollinia are conglutinated. We observed similar vegetative traits among C. falcata f. falcata, C. falcata f. albescens S. Kobayashi, and C. falcata f. conformis. The floral morphology in C. falcata f. conformis resembles that of C. nanchuanica (S.C. Chen) X.H. Jin et X.G. Xiang (i.e., similar petal-like lip and stig- ma position at the column apex; syn.

  • Phytogeographical Analysis and Ecological Factors of the Distribution of Orchidaceae Taxa in the Western Carpathians (Local Study)
    plants Article Phytogeographical Analysis and Ecological Factors of the Distribution of Orchidaceae Taxa in the Western Carpathians (Local study) Lukáš Wittlinger and Lucia Petrikoviˇcová * Department of Geography and Regional Development, Faculty of Natural Sciences, Constantine the Philosopher University in Nitra, 94974 Nitra, Slovakia; [email protected] * Correspondence: [email protected]; Tel.: +421-907-3441-04 Abstract: In the years 2018–2020, we carried out large-scale mapping in the Western Carpathians with a focus on determining the biodiversity of taxa of the family Orchidaceae using field biogeographical research. We evaluated the research using phytogeographic analysis with an emphasis on selected ecological environmental factors (substrate: ecological land unit value, soil reaction (pH), terrain: slope (◦), flow and hydrogeological productivity (m2.s−1) and average annual amounts of global radiation (kWh.m–2). A total of 19 species were found in the area, of which the majority were Cephalenthera longifolia, Cephalenthera damasonium and Anacamptis morio. Rare findings included Epipactis muelleri, Epipactis leptochila and Limodorum abortivum. We determined the ecological demands of the abiotic environment of individual species by means of a functional analysis of communities. The research confirmed that most of the orchids that were studied occurred in acidified, calcified and basophil locations. From the location of the distribution of individual populations, it is clear that they are generally arranged compactly and occasionally scattered, which results in ecological and environmental diversity. During the research, we identified 129 localities with the occurrence of Citation: Wittlinger, L.; Petrikoviˇcová, L. Phytogeographical Analysis and 19 species and subspecies of orchids. We identify the main factors that threaten them and propose Ecological Factors of the Distribution specific measures to protect vulnerable populations.

(Occasional Papers from the Herbarium Greuter – N° 1). — Bocconea. 25: 5-127. 2012. — ISSN 1120-4060 (print), 2280-3882 (online). The material collected during OPTIMA’s Iter Mediterraneum VII to the Peloponnese in 1995 has been revised. It comprises 2708 gatherings, each with 0 to 31 duplicates, collected in 53 numbered localities. The number of taxa (species or subspecies) represented is 1078. As many of the areas visited had been poorly explored before, a dozen of the taxa collected turned out to not to have been previously described, of which 9 (7 species, 2 subspecies) are described and named here (three more were published independently in the intervening years). They belong to the genera Allium, Asperula, Ballota, Klasea, Lolium, Minuartia, Nepeta, Oenanthe, and Trifolium. New combinations at the rank of subspecies (3) and variety (2) are also published. One of the species (Euphorbia aulacosperma) is first recorded for Europe, and several are new for the Peloponnese or had their known range of distribution significantly expanded. Critical notes draw attention to these cases and to taxonomic problems yet to be solved. An overview of the 11 Itinera Mediterranea that have taken place so far is presented, summarising their main results.

  • Ecological Technical Note Longsdon Way, Caterham, Surrey
    Ecological Technical Note Longsdon Way, Caterham, Surrey September 2019 1.0 Introduction 1.1 This Technical Note has been prepared by CSA Environmental on behalf of Croudace Homes Ltd in relation to land at Longsdon Way, Caterham, Surrey (hereafter referred to as, ‘the Site’), centred around Ordnance Survey grid reference TQ 348 551). 1.2 The Site (c.3.96 ha) is being promoted for allocation for residential housing (originally for up to c.60 units). Representations have been made to Tandridge District Council (TDC) for inclusion of a site allocation within the Tandridge ‘Our Local Plan 2033’, however the Site was excluded from further consideration as a result of Regulation 19 consultation. Whilst the evidence base previously provided by TDC confirmed that the Site is not performing Green Belt purposes and as such could be considered for release from the Green Belt, concerns were subsequently raised following publication of their ecology evidence base which identified the Site as ‘ecologically unsuitable’ due to the potential for the Site to be restored to calcareous grassland as S41 (NERC Act, 2006) habitat. The validity of this decision is explored and evaluated within this Technical Note, in light of revised proposals for development of a reduced scale (up to c.40 units), see Development Plan (Ref DES/929/600) provided in Appendix E. 1.3 A review of the Local Plan evidence base documents has been undertaken, and an assessment of the conclusions drawn against site based survey and biological records data commissioned by the applicant,
