A Comparative Study on the Reproductive Success of Two Rewarding Habenaria Species
Zhang and Gao BMC Plant Biology (2021) 21:187 https://doi.org/10.1186/s12870-021-02968-w RESEARCH ARTICLE Open Access A comparative study on the reproductive success of two rewarding Habenaria species (Orchidaceae) occurring in roadside verge habitats Wenliu Zhang1,2 and Jiangyun Gao1,2* Abstract Background: Most orchid species have been shown to be severely pollination limited, and the factors affecting reproductive success have been widely studied. However, the factors determining the reproductive success vary from species to species. Habenaria species typically produce nectar but exhibit variable fruit set and reproductive success among species. Here, we investigated the influence of the flowering plant density, inflorescence size, breeding system, and pollinator behaviour on the reproductive success of two rewarding Habenaria species. Results: Our observations indicated that Habenaria limprichtii and H. petelotii co-occur in roadside verge habitats and present overlapping flowering periods. Both species were pollination limited, although H. limprichtii produced more fruits than H. petelotii under natural conditions during the 3-year investigation. H. petelotii individuals formed distinct patches along roadsides, while nearly all H. limprichtii individuals clustered together. The bigger floral display and higher nectar sugar concentration in H. limprichtii resulted in increased attraction and visits from pollinators. Three species of effective moths pollinated for H. limprichtii, while Thinopteryx delectans (Geometridae) was the exclusive pollinator of H. petelotii. The percentage of viable seeds was significantly lower for hand geitonogamy than for hand cross-pollination in both species. However, H. limprichtii may often be geitonogamously pollinated based on the behaviours of the pollinators and viable embryo assessment. -

The experiences were carried out directly on the field, in Mehedinţi County, Comanesti Hills. In both species of orchids, the seasonal dynamics of photosynthesis registers a peak during the flowering period that corresponds to a maximum content of assimilating pigments and also a maximum leaf surface. In terrestrial orchids, the seasonal dynamics of leaf transpiration intensity is highest during spring, when the water content in the soil is high and minimal in summer. The graphs showing the diurnal variation of photosynthesis for the two species indicate that Cephalanthera longifolia prefers semi-shaded and sunny habitats, while the plants of Platanthera bifolia that are found in the studied areas prefer a more shaded environment INTRODUCTION Orchids that grow directly at the two, more or less globular or digitally- ground level in large areas of Europe or branched tubules. From the main tuber on the grasslands of the tropical regions comes the flowering stem. -

In this context, intraspecific variability with respect to seed morphology (size, weight, and density) was assessed in two close Epipactis tremolsii Pau. populations sharing the same ecological conditions, except for the soil pollution distinguishing one of them. Larger and heavier seeds were found in plants growing on the heavy metal polluted site, while no differences in seed density were detected between seeds produced by plants growing on the contaminated and the control site. Moreover, seed coats and embryos varying together in their dimensions were described in the control population, while coats varying in their size independently from embryos were described in plants growing on the polluted site. Seeds from the two studied populations significantly differed in several parameters suggesting that intraspecific seed variability occurred in the case study.

Phylogenetic Placement of the Enigmatic Orchid Genera Thaia and Tangtsinia: Evidence from Molecular and Morphological Characters

China 3 Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, Menglun Township, Mengla County, Yunnan province 666303, P.R. China Author for correspondence: Xiao-Hua Jin, [email protected] Abstract The phylogenetic position of two enigmatic Asian orchid genera, Thaia and Tangtsinia, were inferred from molecular data and morphological evidence. An analysis of combined plastid data (rbcL + matK + psaB) using Bayesian and parsimony methods revealed that Thaia is a sister group to the higher epidendroids, and tribe Neottieae is polyphyletic unless Thaia is removed. Morphological evidence, such as plicate leaves and corms, the structure of the gynostemium and the micromorphol- ogy of pollinia, also indicates that Thaia should be excluded from Neottieae. Thaieae, a new tribe, is therefore tentatively established. Using Bayesian and parsimony methods, analyses of combined plastid and nuclear datasets (rbcL, matK, psaB, trnL-F, ITS, Xdh) confirmed that the monotypic genus Tangtsinia was nested within and is synonymous with the genus Cepha- lanthera, in which an apical stigma has evolved independently at least twice. -

Kar1 Robatsch Mit Zeichnungen von L. FREIDINGER und C. A. MRKVICKA Zusammenfassung: Die systematische Stellung der Gattung Epipactis in der Subtribus Cephalantherinae wie auch die Stel- lung dieser Subtribus innerhalb der Unterfamilie Neottioideae wird an Beispielen enhvickungsgeschicht- licher Untersuchungen diskutiert. Nach den neuesten molekularen Daten, die aus DNA-Sequenzanalysen gewonnen wurden, ist ein Stammbaum erstellt worden, in dem die Neottioideae in die "epidendroids" eingereiht wurden. Das steht im Widerspruch zu dem in unserer Arbeit praktizierten Klassifikations- System, das in "Die Orcliideen" R. SCHLECHTER in der Bearbeitung von F. BMEGER und K. SENGHAS venvendet wird. Die Ableitung einer Orchideenblüte aus dem Liliiflorae-Erbe ermögliclit eine Differentialdiagnose zwi- schen den Orchidaceae und den Apostasiaceae. Die Apostasiaceae, die viele Autoren als Unterfamilie Apostasioideae zu den Orchidaceae stellen, werden durch vergleichende Blütenanalysen von dieser Familie abgetrennt. Der Entwickiungstendenz des Gynoeceums der Orchideen, durch die es zum Auf- bau eines Rostellums mit seinen Organen kommt, steht die Reduktionstendenz des Gynoeceums der Apostasiaceae, durch die es zu einer Verminderung des ursprünglich trimeren Stigmas kommt, gegen- über.

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.

Rare Plant Monitoring 2017
RARE PLANT MONITORING 2017 Ajuga pyramidalis Ophrys insectifera © Zoe Devlin What is it? In 2017, we decided to carry out a small pilot scheme on rare plant monitoring. Where experienced plant recorders had submitted recent casual records of rare plants to the Centre, they were asked if they would be willing to visit their rare plant population once a year during its flowering period and to count the total number of individuals present. The response to the scheme from the small number of recorders contacted has been overwhelming positive and it has resulted in very valuable data being collected in 2017. Data on the rare plant location, the count and additional information about the site is submitted online through a dedicated web portal set up by the Data Centre. The project was discussed and agreed with the NPWS. It is framed around the 2016 Vascular Plant Red List and is mainly focused on monitoring vulnerable, near threatened and rare least concern species. Why is it important? When assessing the national FAST FACTS 2017 conservation status of very rare species according to IUCN Red List methodology, it is recommended that 37 you use annual population count data. That’s the total number of rare plant Given the numbers of rare plant populations that were monitored in the species a country might have, this 2017 pilot information can be difficult to collect in any volume. This citizen science project relies on the generosity of 22 expert volunteers to ‘keep an eye’ on That’s the number of rare plant species rare populations near them and to that were monitored in 2017 submit standardised count data once a year.
