Pollination of the Lady's Slipper Cypripedium Henryi Rolfe

Examination of the breeding system suggests that the flowers are self-compatible, but need pollen vectors for successful reproduction. The flower is rewardless; over 15 insects belonging to Araneida, Hymenoptera, Diptera, Lepidoptera, and Coleoptera were recorded as flower visitors, but most only alighted or rested on the flower. In the total 32 h of observations over 2 years, female Lasioglossum bees were found to be the most frequent visitors and the only pollinators. They showed a high visitation frequency and, surprisingly, re-visited the same flowers frequently. Cypripedium henryi probably attracts pollinators visiting the flowers through general food deception (odour components, colour, false nectar guides), as well as special structures (slippery labellum, slippery staminode). Although three Lasioglossum species visited the flowers, only L. sauterum Fan et Ebmer was found with pollen. Lasioglossum flavohirtum Ebmer was large and climbed out from the entrance. -
Quantifying Trends of Land Change in Qinghai-Tibet Plateau During 2001–2015
remote sensing Article Quantifying Trends of Land Change in Qinghai-Tibet Plateau during 2001–2015 Chao Wang, Qiong Gao and Mei Yu * Department of Environmental Sciences, University of Puerto Rico, Rio Piedras, San Juan, PR 00936, USA; [email protected] (C.W.); [email protected] (Q.G.) * Correspondence: [email protected]; Tel.: +1-787-764-0000 Received: 1 September 2019; Accepted: 17 October 2019; Published: 20 October 2019 Abstract: The Qinghai-Tibet Plateau (QTP) is among the most sensitive ecosystems to changes in global climate and human activities, and quantifying its consequent change in land-cover land-use (LCLU) is vital for assessing the responses and feedbacks of alpine ecosystems to global climate changes. In this study, we first classified annual LCLU maps from 2001–2015 in QTP from MODIS satellite images, then analyzed the patterns of regional hotspots with significant land changes across QTP, and finally, associated these trends in land change with climate forcing and human activities. The pattern of land changes suggested that forests and closed shrublands experienced substantial expansions in the southeastern mountainous region during 2001–2015 with the expansion of massive meadow loss. Agricultural land abandonment and the conversion by conservation policies existed in QTP, and the newly-reclaimed agricultural land partially offset the loss with the resulting net change of 5.1%. Although the urban area only expanded 586 km2, mainly at the expense of agricultural − land, its rate of change was the largest (41.2%). Surface water exhibited a large expansion of 5866 km2 (10.2%) in the endorheic basins, while mountain glaciers retreated 8894 km2 ( 3.4%) mainly in the − southern and southeastern QTP. -

No. 140 Irish Garden Plant Society Newsletter January 2018 Irish Heritage Daffodils Irish Heritage Daffodils IGPS Newsletter January 2018 Irish Heritage Daffodils Editorial Irish Heritage Daffodils Irish Heritage Daffodils Narcissus ‘Border Beauty’ Mary Montaut, Leinster Branch IGPS Narcissus ‘Border Beauty’ The chilly, bright winter weather just after Christmas made me really appreciate some scented subjects in the garden, especially my favourite Daphne bholua ‘Jacqueline Postil’. I was extremely fortunate many years ago to attend a propagation workshop with IGPS at Kinsealy, and they had rooted cuttings of this glorious plant. I bought one and I have adored it ever since. However, I have recently fallen in love just as passionately with another winter-scented shrub and this one, I believe, might be adopted by IGPS as one of our ‘Irish Heritage’ plants, because it is named after an Irish botanist. The shrub is Edgeworthia chrysantha - the golden-headed Edgeworthia. It belongs to the same family as the Daphne, Thymelaeaceae, and originates from the China - Nepal border area. It is naturalized in Japan, where it was planted in the late sixteenth century for paper making and is called the Paper Bush (Mitsumata). There is also an orange- flowered variety called Akebono which is said to be a smaller shrub, but I have never be lucky enough to see this one. It was first classified in 1841, and named in honour Michael Pakenham Edgeworth. He was a younger brother of the novelist, Maria Edgeworth (of Castle Rackrent fame) and lived and worked in India most of his life. However, I feel we should salute his work, and recommend this superb and tolerant shrub. -
Morphology and Morphogenesis of the Seed Cones of the Cupressaceae - Part II Cupressoideae
1 2 Bull. CCP 4 (2): 51-78. (10.2015) A. Jagel & V.M. Dörken Morphology and morphogenesis of the seed cones of the Cupressaceae - part II Cupressoideae Summary The cone morphology of the Cupressoideae genera Calocedrus, Thuja, Thujopsis, Chamaecyparis, Fokienia, Platycladus, Microbiota, Tetraclinis, Cupressus and Juniperus are presented in young stages, at pollination time as well as at maturity. Typical cone diagrams were drawn for each genus. In contrast to the taxodiaceous Cupressaceae, in Cupressoideae outgrowths of the seed-scale do not exist; the seed scale is completely reduced to the ovules, inserted in the axil of the cone scale. The cone scale represents the bract scale and is not a bract- /seed scale complex as is often postulated. Especially within the strongly derived groups of the Cupressoideae an increased number of ovules and the appearance of more than one row of ovules occurs. The ovules in a row develop centripetally. Each row represents one of ascending accessory shoots. Within a cone the ovules develop from proximal to distal. Within the Cupressoideae a distinct tendency can be observed shifting the fertile zone in distal parts of the cone by reducing sterile elements. In some of the most derived taxa the ovules are no longer (only) inserted axillary, but (additionally) terminal at the end of the cone axis or they alternate to the terminal cone scales (Microbiota, Tetraclinis, Juniperus). Such non-axillary ovules could be regarded as derived from axillary ones (Microbiota) or they develop directly from the apical meristem and represent elements of a terminal short-shoot (Tetraclinis, Juniperus). -

[Received 01.11.2016; Revised & accepted 04.11.2016; Published 31.12.2016] Abstract We report a find of the rare orchid Ponerorchis nana (King & Pantling) Soó (Orchidaceae) from Lachung, Sikkim, and compare it with the very different species P. chusua with which it has previously been associated. Ponerorchis nana is currently known from East Sikkim Eastwards to Central Arunachal Pradesh, and grows on moss-covered cliffs and tree trunks. It seems closely related to Amitostigma pathakianum. Key words: Ponerorchis nana, Identity, Reestablished species Ponerorchis nana (King & Pantling) Soó (Orchidaceae) is a much misunderstood taxon. In Flora of Bhutan (Pearce & Cribb 2002) and on most websites (see references: web-resources) P. nana is said to be either very similar to or synonymous with P. chusua, and the epithet has been used for both narrow-leaved and broad-leaved small individuals of P. Chusua (e.g. Adhikari 2008). The root of the confusion started long lack when King & Pantling (1898) originally described P. nana as a variety of P. chusua and even hinted at intermediates. However, Ponerorchis nana (Figures 1, 2) is very different from P. chusua (Figure 3), in morphology as well as in ecology, and no intermediates are known. Pantling’s original drawing (King & Pantling 1898) shows most of its distinctive features: small and delicate growth; a single linear arcuate channeled leaf with shortly clasping base; 1- to 2-flowered (very rarely 3-flowered) inflorescence; flowers less than half the size of those of P. -

Abstract: Amentotaxus, a genus of Taxaceae, is an ancient lineage with six relic and endangered species. Four Amentotaxus species, namely A. argotaenia, A. formosana, A. yunnanensis, and A. poilanei, are considered a species complex because of their morphological similarities. Small populations of these species are allopatrically distributed in Asian forests. However, only a few codominant markers have been developed and applied to study population genetic structure of these endangered species.
