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. -

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. -

Orchids: 2017 Global Ex Situ Collections Assessment
Orchids: 2017 Global Ex situ Collections Assessment Botanic gardens collectively maintain one-third of Earth's plant diversity. Through their conservation, education, horticulture, and research activities, botanic gardens inspire millions of people each year about the importance of plants. Ophrys apifera (Bernard DuPon) Angraecum conchoglossum With one in five species facing extinction due to threats such (Scott Zona) as habitat loss, climate change, and invasive species, botanic garden ex situ collections serve a central purpose in preventing the loss of species and essential genetic diversity. To support the Global Strategy for Plant Conservation, botanic gardens create integrated conservation programs that utilize diverse partners and innovative techniques. As genetically diverse collections are developed, our collective global safety net against plant extinction is strengthened.

Using the “Seidenfaden collection” in Copenhagen as an example, we address the common view that botanical garden collections of orchids are important for conservation. Seidenfaden collected live orchids all over Thailand from 1957 to 1983 and created a traditional collection for taxonomic research, characterized by high taxonomic diversity and low intraspecific variation. Following an extended period of partial neglect, we managed to set up a five-year project aimed at expanding the collection with a continued focus on taxonomic diversity, but widening the geographic scope to tropical Asia. -
