Picconia Excelsa (Oleaceae)
situation on scoria (e.g. Rangitoto) and perhaps there for the same reasons (excellent drainage? aeration of roots?). Other matters of interest and/or concern were the site of the old native plant plantation and the tragic devastation wrought by possums on the pohutukawas. All our thanks to the leader and the organisers. Received 5 July 1989. PICCONIA EXCELSA (OLEACEAE) R.O. Gardner The current Auckland City Council Proposed District Scheme lists two Picconia excelsa trees in Remuera at St Kentigern School and at 115 Victoria Avenue that are to be protected for their botanical (rarity) value. This species the Canary Islands olive is not mentioned in most horticultural works. It forms a tree of medium size heavy in foliage with the rough bark and crooked branching typical of its family. Sterile specimens have a deceptive likeness to those of Nestegis spp. even having a waxy bloom on the petioles — (like N. cunninghamii but not N. apetala) (Johnson 1957). The older AK material was first determined by Dr Peter Green of Kew. There are several other individuals in Auckland like the above of good size but almost certainly less than a hundred years old. There are trees at 2 Woodside Ave Mt Eden at 277 Mt Eden Rd and on a farmhouse drive in Ihumatao Rd; there is a AK specimen from the Wilson Home in Takapuna and until recently there was a tree in the crater of Mt St John. Perhaps the importation of Picconia might be the result of a nurserymans recognizing that Canary Islands species should flourish in what is literally the opposite side of the world. -
Gradient Analysis of Exotic Species in Pinus Radiata Stands of Tenerife (Canary Islands) S
The Open Forest Science Journal, 2009, 2, 63-69 63 Open Access Gradient Analysis of Exotic Species in Pinus radiata Stands of Tenerife (Canary Islands) S. Fernández-Lugo and J.R. Arévalo* Departamento de Ecología, Facultad de Biología, Universidad de La Laguna, La Laguna 38206, Spain Abstract: Identifying the factors that influence the spread of exotic species is essential for evaluating the present and future extent of plant invasions and for the development of eradication programs. We randomly established a network of 250 plots on an exotic Pinus radiata D. Don plantation on Tenerife Island in order to determine if roads and urban centers are favouring the spread of exotic plant species into the forest. We identified four distinct vegetation groups in the P. radiata stands: advanced laurel forest (ALF), undeveloped laurel forest (ULF), ruderal (RU), and Canarian pine stand (CPS). The groups farthest from roads and urban nuclei (ALF and CPS) have the best conserved vegetation, characterizing by the main species of the potential vegetation of the area and almost no exotic and ruderal species. On the other hand, the groups nearest to human infrastructures (ULF and RU) are characterized by species from potential vegetation’s substitution stages and a higher proportion of exotic and ruderal species. The results indicate distance to roads and urban areas are disturbance factors favouring the presence of exotic and ruderal species into the P. radiata plantation. We propose the eradication of some dangerous exotic species, monitoring of the study area in order to detect any intrusion of alien species in the best conserved areas and implementation of management activities to reduce the perturbation of the ULF and RU areas. -

S. Van Calenbergh Evy Blomme ABSTRACT Schizogyne sericea is a halophytic species widespread throughout all Canary Islands. It has been traditionally used as an analgesic, astringent, anti-inflammatory and wound-healing agent. It is well-known that the chemical composition of a single species may differ with the harvesting region, possibly influencing the biological properties. Lonicera caerulea is a long-living shrub native to the Northern Hemisphere whose berries are a rich source of vitamin C, anthocyanins and flavanols. -
Checklists of Crustacea Decapoda from the Canary and Cape Verde Islands, with an Assessment of Macaronesian and Cape Verde Biogeographic Marine Ecoregions

GONZÁLEZ University of Las Palmas de Gran Canaria, i-UNAT, Campus de Tafira, 35017 Las Palmas de Gran Canaria, Spain. E-mail: [email protected]. ORCID iD: 0000-0001-8584-6731. Abstract The complete list of Canarian marine decapods (last update by González & Quiles 2003, popular book) currently com- prises 374 species/subspecies, grouped in 198 genera and 82 families; whereas the Cape Verdean marine decapods (now fully listed for the first time) are represented by 343 species/subspecies with 201 genera and 80 families. Due to changing environmental conditions, in the last decades many subtropical/tropical taxa have reached the coasts of the Canary Islands. Comparing the carcinofaunal composition and their biogeographic components between the Canary and Cape Verde ar- chipelagos would aid in: validating the appropriateness in separating both archipelagos into different ecoregions (Spalding et al. 2007), and understanding faunal movements between areas of benthic habitat. The consistency of both ecoregions is here compared and validated by assembling their decapod crustacean checklists, analysing their taxa composition, gath- ering their bathymetric data, and comparing their biogeographic patterns. Four main evidences (i.e. different taxa; diver- gent taxa composition; different composition of biogeographic patterns; different endemicity rates) support that separation, especially in coastal benthic decapods; and these parametres combined would be used as a valuable tool at comparing biotas from oceanic archipelagos. -

As the origin of flood events is usually associated with intense precipitation episodes, this study considers the general rainfall characteristics of tourist resorts in two islands of the Canary Archipelago (Spain). Days of intense rainfall were determined using the 99th percentile (99p) of 8 daily precipitation data series. In addition, the weather types that generated these episodes were identified, the best-fitting distribution functions were determined to allow calculation of probable maximum daily precipitation for different return periods, and the territorial and economic consequences of flood events were analysed. The results show highly irregular rainfall, with 99p values ranging 50–80 mm. The weather types associated with 49 days of flooding events were predominantly cyclonic and hybrid cyclonic. The Log Pearson III distribution function best fitted the data series, with a strong likelihood in a 100-year return period of rainfall exceeding 100 mm in a 24 h period. -
Goji Berry—A Novel Nutraceutical “Superfruit” for Florida Master Gardeners1 Yujie Jiao and Guodong Liu2
HS1391 Goji Berry—a Novel Nutraceutical “Superfruit” for Florida Master Gardeners1 Yujie Jiao and Guodong Liu2 Introduction Goji berry (Lycium barbarum L.) is a native shrub to China belonging to the Solanaceae family. Common names of the crop include Chinese wolfberry, Himalayan goji, Tibetan goji, Fruktus Iycii, gougizi, goji berry, matrimony vine, Chinese boxthorn, Ningxia wolfberry, red medlar, and mede berry. It is widely cultivated and used throughout the arid and semiarid regions of northwest China (Figure 1). Figure 1. Branches of goji berry bushes (A) and cultivation in Yinchuan, Goji berries have been used in both fresh and processed Ningxia, in northern China (B). forms for food and medicine for more than 4,000 years in Credits: Yuwang Luan, Yinchuan, Ningxia, China China (Wang et al. 2015). The goji berry fruit is known This crop can be grown in Plant Hardiness Zones 4b to 9b as a “superfruit” thanks to its high levels of vitamins and as defined by the US Department of Agriculture (USDA) minerals, as well as other medicinal benefits recognized in (Figure 2). Therefore, most of Florida’s climate is favorable many countries around the world. The term “superfruit” is for goji berry, and a few Florida growers have cultivated it frequently used to refer to fruit extraordinarily rich in anti- for years. This species can tolerate infertile and unfavorable oxidants and nutrients (Chang et al. 2018; Himelrick 2018). growth conditions and hence can be mistakenly considered Goji berry has nutraceutical properties.

Morphological Nature of Floral Cup in Lauraceae
l~Yoc. Indian Acad. Sci., Vol. 88 B, Part iI, Number 4, July 1979, pp. 277-281, @ printed in India. Morphological nature of floral cup in Lauraceae S PAL School of Plant Morphology, Meerut College, Meerut 250 001 MS received 19 June 1978 Abstract. On the basis of anatomical criteria the floral cup of Lauraceae can be regarded as appendicular, as the traces entering into the floral cup are morphologi- cally compound, differentiated into tepal and stamen traces at higher levels. The ontogenetic studies also support this contention. The term Perigynous hypanthium is retained for the floral cup of Lauraceae as it is formed as a result of intercalary growth occurring underneath the region of perianth and androecium. Keywords. Lauraceae; floral cup; morphological nature; appendicular; peri- gynous hypanthium. 1. Introduction The family Lauraceae has received comparatively little attention from earlier workers because of difficulty in procuring the material. So far very little work has been done on the floral anatomy of this family (Reece 1939 ; Sastri 1952 ; Pal 1974). There has been considerable difference of opinion regarding the nature of floral cup in angiosperms. The present work was initiated to study the morphological nature of the floral cup. 2. Materials and methods The present investigation embodies the results of observations on 21 species of the Lauraceae.

A LONS O5 an d Luis M . C ARRASCA L6 SUMMARY .— New data on the population, distribution and habitat preferences of the Canary Islands stonechat Saxicola dacotiae . This paper updates estimates of population size, distribution and habitat preferences of the endemic Canary Islands stonechat Saxicola dacotiae on the basis of data gathered across their whole distribution range, the island of Fuerteventura. We surveyed 1,462 0.5-km line transects during the reproductive seasons in 2005 and 2006, distributed across the whole island. Results were used to estimate population size using two methods: stratified estimates of mean densities and sum of estimated abundances across strata, and sum of estimations of abundance in 1 km x 1 km UTM squares based on statistical models built by boosted regression trees (BRT). In both methods we accounted for the effects of bird detectability in transects. Overall, 490 mature individuals were recorded. The Canary Islands stonechat preferred high, steep terrain (particularly above 20% slope and 200 m a.s.l.) and selected negatively the lower and flatter areas comprising most of the island. These habitats were occupied, however, albeit at low density. The highest average densities sampled per habitat (up to 43 birds/km 2) were registered on steep areas (> 11%) with scrub, although the statistical models predicted densities of 66 birds/km 2 in the optimum 1 Grupo de Ecología Terrestre (TEG), Departamento de Ecología, Universidad Autónoma de Madrid . -
The Laurel Or Bay Forests of the Canary Islands
California Avocado Society 1989 Yearbook 73:145-147 The Laurel or Bay Forests of the Canary Islands C.A. Schroeder Department of Biology, University of California, Los Angeles The Canary Islands, located about 800 miles southwest of the Strait of Gibraltar, are operated under the government of Spain. There are five islands which extend from 15 °W to 18 °W longitude and between 29° and 28° North latitude. The climate is Mediterranean. The two eastern islands, Fuerteventura and Lanzarote, are affected by the Sahara Desert of the mainland; hence they are relatively barren and very arid. The northeast trade winds bring moisture from the sea to the western islands of Hierro, Gomera, La Palma, Tenerife, and Gran Canaria. The southern ends of these islands are in rain shadows, hence are dry, while the northern parts support a more luxuriant vegetation. The Canary Islands were prominent in the explorations of Christopher Columbus, who stopped at Gomera to outfit and supply his fleet prior to sailing "off the map" to the New World in 1492. Return voyages by Columbus and other early explorers were via the Canary Islands, hence many plants from the New World were first established at these points in the Old World. It is suspected that possibly some of the oldest potato germplasm still exists in these islands. Man exploited the islands by growing sugar cane, and later Mesembryanthemum crystallinum for the extraction of soda, cochineal cactus, tomatoes, potatoes, and finally bananas. The banana industry is slowly giving way to floral crops such as strelitzia, carnations, chrysanthemums, and several new exotic fruits such as avocado, mango, papaya, and carambola.
