The North American flowering of the cultivated fountain bamboo, Fargesia nitida (Poaceae: Bambusoideae), in Vancouver, BC

Thu, 15 Nov 2007 19:09:12 -0800

Abstract or Summary:

Fargesia nitida, the fountain bamboo, is a hardy and attractive bamboo that is commonly cultivated in North America. Because its reproductive structures were not known until recently, there have been several taxonomic issues with this species. Fargesia nitida began flowering in 1993 in the United Kingdom for the first time since its original collection in its native China in 1886, and it has since been expected to flower in North America. Here I document its recent flowering in Vancouver, British Columbia, and I provide a morphological description of flowering individuals of this species.

Carrierea calycina, the goat horn tree - a two part account of its history in western cultivation and recent reintroduction

Thu, 15 Nov 2007 18:20:42 -0800

Abstract or Summary:

Carrierea calycina, a tree in the Flacourtiaceae, was collected by the plant explorer, E. H. Wilson, in 1908 and introduced to the United Kingdom from seed obtained in western Sichuan (Mupin). The plants were raised in the U.K. by Messers. Veitch and Sons, and distributed in 1912 as part of their closing sale…It seemed that the only surviving specimen in the British Isles was at Birr Castle in Eire, but a second was later found at Rowallane in Northern Ireland. I reintroduced this tree to cultivation some 20 years after I was employed as curator of the David C. Lam Asian Garden at the University of British Columbia (UBC) Botanical Garden.

Floral resources for hummingbirds in the arboretum of the Rio de Janeiro Botanical Garden, Brazil

Mon, 27 Aug 2007 17:48:00 -0700

Abstract or Summary:

Floral rewards for hummingbirds were studied in the arboretum of the Rio de Janeiro Botanical Garden. Twenty nine species were visited and between eight and nineteen species flowered each month, with a greater occurrence of species flowering during the austral winter, contrasting with the pattern of adjacent forest areas. Seventeen species (59%) were from America, mostly from South or South and Central America (thirteen species), and remaining species were from Central and/or North America. Most plant species fit into the hummingbird pollination syndrome and seven out of the twelve species from other continents fit into the perching-bird pollination syndrome, indicating that hummingbirds prefer flowers supposedly adapted to birds. Four species of hummingbirds were observed visiting flowers and two others were registered in the arboretum, representing less than half of the species registered in the forests of the region. The only resident species of the arboretum, Thalurania glaucopis Gmelim visited most species, exhibited territorial behaviour and was by far the most common species. Although the floral resources of the arboretum seemed to support the individuals of T. glaucopsis and could function as an additional resource for the hummingbirds from the adjacent forests, a higher diversity of both floral resources and micro-sites are recommended to make the arboretum and equivalent areas more hummingbird-friendly.

Hummingbird flowers of British Columbia

Mon, 27 Aug 2007 17:38:43 -0700

Abstract or Summary:

Aquilegia formosa, Castilleja hispida, C. miniata, C. rhexifolia, C. rupicola, Gilia aggregata, Lonicera ciliosa, Ribes lobbii, and Stachys cooleyae are the plant species in British Columbia which best fit the syndrome of hummingbird pollination. Impatiens capensis, I. noli-tangere, Lilium columbianum, Lonicera dioica, Monarda fistulosa, Ribes sanguineum, and Rubus spectabilis have mixed or transitional pollination strategies, being pollinated by both insects and hummingbirds. Examples of opportunistic nectar foraging by hummingbirds are recorded for several other species.
