Scalesia
''Scalesia'' is a genus in the family Asteraceae endemic to the Galapagos Islands. It contains fifteen species that grow as shrubs or trees. This is unusual, because tree species are uncommon in Asteraceae. The genus ''Scalesia'' resulted from a blunder by Arnott who named it in honour of "W. Scales Esq., Cawdor Castle, Elginshire" but discovered after publication that the name should have read 'Stables', after Scottish botanist, William Alexander Stables (1810–1890). All of the species have soft, pithy wood. ''Scalesia'' species have been called "the Darwin's finches of the plant world" because they show a similarly dramatic pattern of adaptive radiation. One of the largest and most widespread species is '' Scalesia pedunculata'' – a large tree which grows up to 15 to 20 metres tall, reaching maturity in a few years time. These trees typically grow in dense stands of the same species and age. They die around the same time, and then a new generation of seedlings grows up in ...

Scalesia Pedunculata
''Scalesia pedunculata'' is a flowering plant species in the family Asteraceae, growing to a slender tree (20m tall, DBH 20 cm), and found in dense stands on the humid windward coasts of the islands of Santa Cruz, San Cristobal, Santiago and Floreana in the Galapagos Islands. The Galapagos archipelago lies in the southeast trade wind zone, so that climate and weather are dominated by the moisture-bearing trade winds and the topography of the islands. In general, the windward sides of the islands have a much higher precipitation than the leeward sides. ''Scalesia pedunculata'' is regarded as vulnerable because of human encroachment, invasive introduced plant species such as ''Cedrela odorata'' and ''Psidium guajava'', and grazing by introduced goats. Fires and cutting for fuel are also contributory problems, though the tree's wood is soft, with a large, pithy centre. The inflorescences are capitulae on long peduncles and composed of disc florets only with no ray flore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scalesia Affinis
''Scalesia affinis'' is a species of flowering plant in the family Asteraceae. It is endemic to the Galápagos Islands, Ecuador. It is one of the most widely distributed ''Scalesia'' species and occurs on four major islands: Fernandina Island, Isabela Island (main distribution area), Santa Cruz Island and Floreana Island. Populations from Santa Cruz and Floreana display some morphological and genetic divergence from populations of Fernandina Island Fernandina Island () is the youngest and third largest island in the Galápagos, as well as the furthest west. It has an area of and a height of , with a summit caldera about wide. It is younger than Isabela, being only less than one million ... and Isabela Island. References * Eliasson, U.H. 1974.
