gaylussacia การใช้

• "Gaylussacia " plants are often a component of an oak-heath forest.
• The larvae feed on Ericaceae species, including " Leiophyllum buxifolium " and probably " Gaylussacia " species.
• "Gaylussacia bigeloviana " is a shrub up to 1 m ( 40 inches ) tall, sometimes forming small colonies.
• "Gaylussacia mosieri " is a shrub up to 150 cm ( 5 feet ) tall, sometimes forming small colonies.
• "Gaylussacia orocola " is a shrub up to 100 cm ( 40 inches ) tall, sometimes forming small colonies.
• "Gaylussacia ursina " is a shrub up to 200 cm ( 80 inches ) tall, sometimes forming huge colonies.
• "Gaylussacia nana " is a shrub up to 1 m ( 40 inches ) tall, sometimes forming large colonies of hundreds of individuals.
• The understory is thick with shrubs, including black huckleberry ( " Gaylussacia baccata " ) and early lowbush blueberry ( " Vaccinium pallidum " ).
• "Gaylussacia tomentosa " is a shrub up to 200 cm ( 80 inches ) tall, spreading by means of underground rhizomes hence sometimes forming huge colonies.
• "Gaylussacia brachycera " is easily distinguished from other members of its genus by its leaves : they resemble those of boxwood ( hence its name ) and lack the resin glands typical of huckleberries.
• The shrub layer may be well-developed, with hillside blueberry ( " Vaccinium pallidum " ), black huckleberry ( " Gaylussacia baccata " ), or other acid-tolerant species most characteristic.
• Shrubs such as hillside blueberry ( " Vaccinium pallidum " ), black huckleberry ( " Gaylussacia baccata " ), and mountain laurel ( " Kalmia latifolia " ) are common in the understory and can form a dense layer.
• Typical woody understory and shrub layer species include moosewood ( " Acer pensylvanicum " ), low-bush blueberry ( " Vaccinium angustifolium " ) and other heath species especially the genera " Gaylussacia " and " Vaccinium ".
• The most common vegetation community type in uplands is Pine / Oak Forest, composed of the typical pines and various oaks ( " Quercus " spp . ), with an understory of ericacious shrubs, mainly huckleberries ( " Gaylussacia " spp . ).
• More recently, phylogenetic studies in 2002 suggested that the monophyly of " G . brachycera " with the remainder of " Gaylussacia " is " equivocal ", and further analysis of " Vaccinium " might result in " G . brachycera " being returned to that genus.
• It was redesignated " G . brachycera " in 1846 by Asa Gray on the basis of Baird's specimens . ( " Gaylussacia " was not recognized as a genus separate from " Vaccinium " until 1819 . ) The discovery brought about a friendship between Gray and Baird that ultimately resulted in the latter's appointment as secretary of the Smithsonian Institution.
