Received: 18 May 2020; Accepted: 2 June 2020; Published: 3 June 2020 Abstract: The genera Dracaena and Sansevieria (Asparagaceae, Nolinoideae) are still poorly resolved phylogenetically. Plants of these genera are commonly distributed in Africa, China, Southeast Asia, and America. Most of them are cultivated for ornamental and medicinal purposes and are used in various traditional medicines due to the wide range of ethnopharmacological properties. Extensive in vivo and in vitro tests have been carried out to prove the ethnopharmacological claims and other bioactivities. These investigations have been accompanied by the isolation and identification of hundreds of phytochemical constituents. The most characteristic metabolites are steroids, flavonoids, stilbenes, and saponins; many of them exhibit potent analgesic, anti-inflammatory, antimicrobial, antioxidant, antiproliferative, and cytotoxic activities. This review highlights the structures and bioactivities of flavonoids and stilbenoids isolated from Dracaena and Sansevieria. Keywords: Dracaena; Sansevieria; biological/pharmacological activities; flavonoids; stilbenoids 1. Introduction The taxonomic boundaries of the dracaenoid genera Dracaena and Sansevieria have long been debated. -

Phylogeny of Southern African and Australasian Wahlenbergioids (Campanulaceae) based on ITS and trnL-F sequence data: implications for a reclassification Christopher N. Cupido , Jessica M. Prebble , and William M. M. Eddie Abstract The Campanulaceae: Wahlenbergioideae currently comprises 15 genera, one of which, Wahlenbergia, is widespread over the southern continents. Southern Africa is the region with maximum wahlenbergioid diversity with 12 genera and approximately 252 species. A second center is Australasia with 38 Wahlenbergia species. This study used a broad sample of wahlenbergioid diversity from South Africa, Australia, and New Zealand to reconstruct a phylogeny based on chloroplast trnL-F and nuclear ITS sequences. Data were analyzed separately and in combination using parsimony and Bayesian methods. The results suggest that for the wahlenbergioids to be monophyletic Wahlenbergia hederacea has to be excluded and that none of the South African, Australian or New Zealand lineages are strictly monophyletic. There are five species assemblages that are in some disagreement with current classification in the family. Wahlenbergia, Prismatocarpus and Roella are shown to be non-monophyletic and implications for a reclassification are presented. Careful consideration of morphological characters is suggested before the adjustment of generic circumscriptions can be accomplished. Recent family-wide molecular phylogenetic studies have supported the view that the Campanulaceae s.s. -

Ethnobotanical Survey of Dracaena Cinnabari and Investigation of the Pharmacognostical Properties, Antifungal and Antioxidant Activity of Its Resin
plants Communication Ethnobotanical Survey of Dracaena cinnabari and Investigation of the Pharmacognostical Properties, Antifungal and Antioxidant Activity of Its Resin Mohamed Al-Fatimi Department of Pharmacognosy, Faculty of Pharmacy, Aden University, P.O. Box 5411, Maalla, Aden, Yemen; [email protected] Received: 28 September 2018; Accepted: 24 October 2018; Published: 26 October 2018 Abstract: Dracaena cinnabari Balf. f. (Dracaenaceae) is an important plant endemic to Soqotra Island, Yemen. Dragon’s blood (Dam Alakhwin) is the resin that exudes from the plant stem. The ethnobotanical survey was carried out by semi-structured questionnaires and open interviews to document the ethnobotanical data of the plant. According to the collected ethnobotanical data, the resin of D. cinnabari is widely used in the traditional folk medicine in Soqotra for treatment of dermal, dental, eye and gastrointestinal diseases in humans. The resin samples found on the local Yemeni markets were partly or totally substituted by different adulterants. Organoleptic properties, solubility and extractive value were demonstrated as preliminary methods to identify the authentic pure Soqotri resin as well as the adulterants. In addition, the resin extracts and its solution in methanol were investigated for their in vitro antifungal activities against six human pathogenic fungal strains by the agar diffusion method, for antioxidant activities using the DPPH assay and for cytotoxic activity using the neutral red uptake assay. The crude authentic resin dissolves completely in methanol. In comparison with different resin extracts, the methanolic solution of the whole resin showed the strongest biological activities. It showed strong antifungal activity, especially against Microsporum gypseum and Trichophyton mentagrophytes besides antioxidant activities and toxicity against FL-cells. -

The Canary Islands
The Canary Islands Dragon Trees & Blue Chaffinches A Greentours Tour Report 7th – 16th February 2014 Leader Başak Gardner Day 1 07.02.2014 To El Patio via Guia de Isora I met the half of the group at the airport just before midday and headed towards El Guincho where our lovely hotel located. We took the semi coastal road up seeing the xerophytic scrub gradually changing to thermophile woodland and then turned towards El Teide mountain into evergreen tree zone where the main tree was Pinus canariensis. Finally found a suitable place to stop and then walked into forest to see our rare orchid, Himantoglossum metlesicsiana. There it was standing on its own in perfect condition. We took as many pics as possible and had our picnic there as well. We returned to the main road and not long after we stopped by the road side spotting several flowering Aeonium holochrysum. It was a very good stop to have a feeling of typical Canary Islands flora. We encountered plants like Euphorbia broussonetii and canariensis, Kleinia neriifolia, Argyranthemum gracile, Aeonium urbicum, Lavandula canariensis, Sonchus canariensis, Rumex lunaria and Rubia fruticosa. Driving through the windy roads we finally came to Icod De Los Vinos to see the oldest Dragon Tree. They made a little garden of native plants with some labels on and the huge old Dragon Tree in the middle. After spending some time looking at the plants that we will see in natural habitats in the following days we drove to our hotel only five minutes away. The hotel has an impressive drive that you can see the huge area of banana plantations around it. -

Box 97, 3922, Cowes, VIC, 13 Australia. 14 1 15 Summary 16 Capsule - Flowers of an invasive plant species are more visited by native birds than 17 flowers of ornithophilous endemic plants. 18 Aims - To describe the bird guild and its behaviour visiting the century plant Agave 19 americana in an insular environment and to determine which factors are affecting 20 visitation rates. 21 Methods - We noted number and species of birds visiting inflorescences during two- 22 hour periods. We used multi-model inference of generalized linear models to analyse 23 the factors affecting the number of visits and the visitor species richness. 24 Results - 81% of inflorescences were visited by eight native bird species. All species 25 fed on nectar and only the Atlantic Canary fed also on pollen. Foraging behaviour 26 varied among species. Visitation rate increased with density and diversity of birds and 27 flower characteristics and decreased through the day. The number of species visiting the 28 inflorescences increased with diversity and density of birds in the surroundings and 29 decreased through the day. -

YEO University Botanic Garden, Cambridge Introduction On the grounds that I was a botanist with an interest in insects I was asked many years ago to participate in the writing of a book on pollination. The book is due to appear soon (Proctor and Yeo, in the press). My contribution to it is largely based on previous publications and I have not done any experi- mental work on the subject. However, I have made some observations from time to time and some of these seem to be worth publishing, though most are not suitable for inclusion in the forthcoming book. These, together with some thoughts stimulated by the literature and my continuous contact with British and exotic plants in the Cambridge Botanic Garden, form the very mixed bag of notes presented here.

Resolving the Evolutionary History of Campanula (Campanulaceae) in Western North America Barry M. Wendling, Kurt E. Galbreath, Eric G. DeChaine* Department of Biology, Western Washington University, Bellingham, Washington, United States of America Abstract Recent phylogenetic works have begun to address long-standing questions regarding the systematics of Campanula (Campanulaceae). Yet, aspects of the evolutionary history, particularly in northwestern North America, remain unresolved. Thus, our primary goal in this study was to infer the phylogenetic positions of northwestern Campanula species within the greater Campanuloideae tree. We combined new sequence data from 5 markers (atpB, rbcL, matK, and trnL-F regions of the chloroplast and the nuclear ITS) representing 12 species of Campanula with previously published datasets for worldwide campanuloids, allowing us to include approximately 75% of North American Campanuleae in a phylogenetic analysis of the Campanuloideae. -

On this, the second ‘Go Slow’ tour, we were able to enjoy some of the best of the island’s rugged volcanic scenery, appreciating the contrasts between the different habitats such as the bird- and flower-rich Laurel forest and the dramatic ravines, and the bare rain-starved slopes of the south. The sunset from the edge of the Big Caldera in the central mountains, the wonderful boat trip, with our close encounters with Atlantic Spotted Dolphins and Cory’s Shearwater, the Gran Canarian Blue Chaffinch and the vagrant Abyssinian Roller, the echoes of past cultures in the caves of Guayadeque, and the beauty of the Botanic Garden with its Giant Lizards were just some of the many highlights. There was also time to relax and enjoy the pools in our delightful hotel overlooking the sea. Good weather with plenty of sunshine, comfortable accommodation, delicious food and great company all made for an excellent week.
