There has been little chance of us standing still with what has been going on here in 2015. The year started well with the birth of our sixth grandchild. January into February had Sue and I in Colombia for our first winter/early spring expedition. It was exhilarating, we were able to travel much further afield than we had previously, as the mountainous areas become safer to travel. We are looking forward to working ever closer with the Colombian institutes, such as the Medellin Botanic Gardens whom we met up with. Consequently we were absent from the RHS February Show at Vincent Square. We are finding it increasingly expensive participating in the London shows, while re-branding the RHS February Show as a potato event hardly encourages our type of customer base to visit. A long standing speaking engagement and a last minute change of date, meant that we missed going to Fota near Cork last spring, no such problem this coming year. We were pleasantly surprised at the level of interest at the Trgrehan Garden Rare Plant Fair, in Cornwall. Hopefully this will become an annual event for us, as well as the Cornwall Garden Society show in April. Poor Sue went through the wars having to have a rush hysterectomy in June, after some timely results revealed future risks.

HEARN Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, Arizona 85721, USA ([email protected]) ABSTRACT To understand evolutionary patterns and processes that account for anatomical diversity in relation to ecology and life form diversity, anatomy of storage roots and stems of the genus Adenia (Passifloraceae) were analyzed using an explicit phylogenetic context. Over 65,000 measurements are reported for 47 quantitative and qualitative traits from 58 species in the genus. Vestiges of lianous ancestry were apparent throughout the group, as treelets and lianous taxa alike share relatively short, often wide, vessel elements with simple, transverse perforation plates, and alternate lateral wall pitting; fibriform vessel elements, tracheids associated with vessels, and libriform fibers as additional tracheary elements; and well-developed axial parenchyma. Multiple cambial variants were observed, including anomalous parenchyma proliferation, anomalous vascular strands, successive cambia, and a novel type of intraxylary phloem.

The essential oils were obtained by microwave assisted hydrodistillation (MWHD) extraction method using Clevenger apparatus and were analyzed by gas chromatography mass spectrometry (GC-MS). Fifty compounds were identified altogether. The majority compounds were the squalene (34.92%), pentadecanal (15.28%) and ionol (19.16%) in shells, juice and seeds respectively. However, aromatic compounds, sesquiterpenes, alcohols, aldehydes and hydrocarbons were detected as minority compounds with potential utility in food and pharma industry.

  • Juvenile Resilience and Adult Longevity Explain Residual Populations of the Andean Wax Palm Ceroxylon Quindiuense After Deforestation
    Juvenile Resilience and Adult Longevity Explain Residual Populations of the Andean Wax Palm Ceroxylon quindiuense after Deforestation María José Sanín1*, Fabien Anthelme2,3, Jean-Christophe Pintaud3, Gloria Galeano1, Rodrigo Bernal1 1 Instituto de Ciencias Naturales, Universidad Nacional de Colombia, Bogotá, Distrito Capital, Colombia, 2 Botanique et Bioinformatique de l’Architecture des Plantes, Recherche Agronomique pour Le Développement, Institut de recherche pour le développement, Montpellier, Hérault, France, 3 Botanique et Bioinformatique de l’Architecture des Plantes and Diversité Adaptation et Développement des plantes, Institut de recherche pour le développement, Montpellier, Hérault, France Abstract Wax palms are an important element of the cloud forests in the tropical Andes. Despite heavy deforestation, the density of adults seems to be similar in deforested pastures as in forests. We aimed to infer the mechanisms responsible for this apparent resilience in pastures and we tested two hypotheses to explain it: 1) adult palms survived in pastures because they were spared from logging, and 2) adults occurred in pastures through the resilience of large juvenile rosettes, which survived through subterranean meristems and later developed into adults. For this purpose, we characterized the demographic structure of C. quindiuense in a total of 122 plots of 400 m2 in forests and pastures at two sites with contrasted land use histories in Colombia and Peru. Additionally, we implemented growth models that allowed us to estimate the age of individuals at four sites. These data were combined with information collected from local land managers in order to complete our knowledge on the land use history at each site. At two sites, the presence of old individuals up to 169 years and a wide age range evidenced that, at least, a portion of current adults in pastures were spared from logging at the time of deforestation.

  • Passiflora Tarminiana, a New Cultivated Species of Passiflora Subgenus
    Novon 11(1): 8–15. 2001 Passiflora tarminiana, a new cultivated species of Passiflora subgenus Tacsonia. Geo Coppens d'Eeckenbrugge1, Victoria E. Barney1, Peter Møller Jørgensen2, John M. MacDougal2 1CIRAD-FLHOR/IPGRI Project for Neotropical Fruits, c/o CIAT, A.A. 6713, Cali Colombia 2Missouri Botanical Garden, P.O. Box 299, St Louis, Missouri 63166-0299, U.S.A. Abstract The new species Passiflora tarminiana differs from its closes relative by the character combination of very small acicular stipules and large almost reflexed petals and sepals. This species has escaped detection despite being widely cultivated. Naturalized populations, particularly on Hawa'ii, have created problems for conservation of the native flora. In Colombia it is more frequently adopted in industrial cultivation because of its rusticity and resistance to fungal diseases. Introduction Passifloras of the subgenus Tacsonia are cultivated by many small farmers, from Venezuela to Bolivia. Some species are cultivated in New Zealand. The main cultivated species is Passiflora mollissima (Kunth) Bailey (Escobar, 1980 & 1988), also called P. Coppens et al. 2000 Passiflora tarminiana 2 tripartita var. mollissima (Kunth) Holm-Nielsen & P. Jørgensen (Holm-Nielsen et al., 1988). It is called "curuba de Castilla" in Colombia, "tacso de Castilla" in Ecuador, and “banana passionfruit” in English-speaking countries.. The second species of importance in the Andes is "curuba india," "curuba ecuatoriana," or "curuba quiteña" in Colombia, called "tacso amarillo" in Ecuador (Pérez Arbeláez, 1978; A.A.A., 1992; Campos, 1992). It is most frequently found in private gardens, but some commercial growers have, because of its rusticity, started to grow it instead of the "curuba de Castilla." We describe this overlooked cultigen as a new species under the name Passiflora tarminiana, in recognition of Tarmín Campos, a Colombian agronomist who contributed with enthusiasm to the development of banana passion fruit cultivation and introduced the first author to the cultivated passifloras of the central Colombian highlands.

Processes of urbanization, expansion of the agricultural and livestock area, among 19 others, have increased its level of threat. Protecting this palm from extinction is important at an ecological level, given 20 its function as a key species in Andean ecosystems. This work evaluated the diversity and population genetic structure 21 of the wax palm from Quindío in five populations of the Colombian coffee region eco-region (Andean zone) by using 22 ten microsatellite molecular markers.

    New Tradition for the Catholic Church saves Palms and Parrots By PAUL SALAMAN Wax Palms (Ceroxylon quindiuense) - the world's tallest palm and an endangered species - are massacred each Easter to provide palm fronds for the Palm Sunday processions and used to adorn churches throughout the Colombian Andes (See Paul Salaman.
