  • 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.

There are 46 species of Aloe in Ethiopia in which about 66% of these • Diversity Aloe species are endemic to the country. They are distributed in all floristic regions. Aloes are very important source of traditional medicine in Ethiopian communities to treat different ailments. In addition Aloes are used in soap production, jute sacks production, anti-microbial activities in cotton fabric, as thickening agent, degraded land rehabilitation and source of food for animals. Although there have been some attempts to conduct researches on Ethiopian Aloe species, the available information especially on commercial use, industrial use, propagation, germination and farming are insignificant and overlooked. As their distribution indicate Aloes are important component of Ethiopian dry-land ecosystem including pastoralist and agro-pastoralist area in which the amount of rain is low. In this area introducing Aloe farm system could be better alternative of poverty reduction and income generation.

  • Contributions to the Systematics and Biocultural Value of Aloe L
    SUMMARY Contributions to the systematics and biocultural value of Aloe L. (Asphodelaceae) Olwen Megan Grace Submitted in partial fulfilment of the requirements for the degree PHILOSOPHIAE DOCTOR in the Faculty of Natural and Agricultural Sciences (Department of Plant Science) University of Pretoria March 2009 Supervisor: Prof. Dr. A. E. van Wyk Co-Supervisor: Prof. Dr. G. F. Smith This thesis focuses on the biocultural value of Aloe L. (Asphodelaceae), the influence of utility on taxonomic complexity and conservation concern, and the systematics and phylogeny of section Pictae, the spotted or maculate group. The first comprehensive ethnobotanical study of Aloe (excluding the cultivated A. vera) was undertaken using the literature as a surrogate for data gathered by interview methods. Over 1400 use records representing 173 species were gathered, the majority (74%) of which described medicinal uses, including species used for natural products such as A. ferox Mill. and A. perryi Baker. In southern Africa, 53% of approximately 120 Aloe species in the region are used for health and wellbeing. Homogeneity in the literature was quantified using consensus analysis; consensus ratios showed that, overall, uses of Aloe spp. for medicine and invertebrate pest control are of the greatest biocultural importance. The rich ethnobotanical history and contemporary value of Aloe substantiate the need for conservation to mitigate the risks of exploitation and habitat loss. A systematic evaluation of the problematic maculate species complex, section Pictae Salm-Dyck, was undertaken. In a phylogenetic study, new sequences were acquired of the nuclear ribosomal internal transcribed spacer (ITS), chloroplast trnL intron, trnL–F spacer 131 and matK gene in 29 maculate species of Aloe .

Their isolation has given rise to many endemic species and subspecies, of which the great views of Tenerife Blue Chaffinch in perfect light were a highlight for many. We marvelled over the flora, so different to that of mainland Europe, and enjoyed the various species of lizards, plus the butterflies and other invertebrates we encountered. The day on La Gomera was a delight, not least for the numbers of Cory’s Shearwaters, whales and dolphins, plus the White-faced Storm Petrels we encountered. Lovely weather with plenty of sunshine, comfortable accommodation, good food and great company all made for an excellent week. Day 1 Saturday 23rd February Fly to Tenerife South – La Chafiras – Road to Vilaflor Fifteen tour group members met with Andrew and Jessica at Gatwick’s North Terminal for the 6.50am Easyjet flight to Tenerife South Airport. After a bit of a delay due to fog at Gatwick, we landed on the island at around 12.15pm, meeting up with our last group member, who had arrived on the island the previous day.

  • Structure of Vegetation in the Canary Islands
    Structure oj Vegetation in the Canary Islands by Kornelius Lems t Goucher College, Baltimore, Maryland U.S.A. (Recibido en la redacción: 17-1-1968) ESTRUCTURA DE LA VEGETACION EN LAS ISLAS RESUMEN 1. Este estudio intenta describir dos asociaciones arbustivas, una en la parte oc- cidental de Tenerife, dominado por la tabaiba roja, Euphorbia atropurpurea, con césped de hierbas anuales, la otra en Fuerteventura, su aspecto dominado por verocíe, Kleinia ncriifolia, y espina blanca, Asparagus albus. 2. La estructura de la vegetación ha sido descrito según el sistema fisionómico de Dansereau. Las dos comunidades vegetales son parecidas salvo en la abundan- cia dc cspinas en la asociación de Klciriia - Asparu~qus,y las gramíneas mas extendidas en la asociación de Euphorbia atropurpurea. 3. Cada especie tiene un "valor de importmcia" calculado de su frecuencia re- lativa y qii rlnmininria re!ltivl. E! ?&z! le !*u .,deres Yc imp~;ti;nciü dc tudas especies en cada asociación llega a 100. 4. Para el análisiq de las formas biológicas se utiliza un sistema derivado de obras de Raunkiaer (1934), Du Rietz (1931), y Schmid (1956). Tipo biológico, ra- mificación, sistema de raices, caída de las hojas, tipo de inflorescencia, y di- semínulos están incluidos en este sistema. 5. Diferencias entre las dos comunidades vegetales existen en: la importancia menor dc hierbas anuales de la asociación de KIeinia y Aspnragus, plantas más ramificadas con hojas más caducas de la misma, las inflorescencias más peque- ñas y más escondidas, y los disemínulos de la misma asociación adaptados al transporte por el viento y por los pájaros.
