Corymbia ficifolia , широко известная как красная цветущая жвачка , [ 2 ] является видом небольшого дерева, которое является эндемичным к юго-западу от Западной Австралии. Он имеет грубую волокнистую кору на багажнике и ветвях, в форме яйца, до широкого копья для взрослых листьев, цветочных бутонов в группах из семи, ярко-красных, розовых или оранжевых цветов и фруктов в форме урны. Он имеет ограниченное распределение в дикой природе, но является одним из наиболее часто посаженных декоративных евкалиптов.
Описание
[ редактировать ]Corymbia ficifolia - это страшное дерево, которое обычно растет до высоты 10 м (33 фута) и образует лигнотубер . У него грубая, волокнистая коричневатая кора на багажнике и ветвях. Взрослые листья тусклые и слегка глянцевые, бледные на нижней поверхности, яйцевая форма с широким копья черепок . 8–20 мм (0,3–0,8 дюйма) длиной Цветочные почки расположены на концах ветвей на разветвленной плодоношке 15–32 мм (0,6–1,3 дюйма) длиной, каждая ветвь цветоножки с семью почками на цветоногих длине 13–27 мм (0,5–1,1 дюйма). Зрелые почки имеют овальную или грушевидную, длиной 12–18 мм (0,5–0,7 дюйма) и шириной 6–8 мм (0,24–0,31 дюйма) с округлым до сплющенного оперкулума . Цветение происходит с декабря по май, а цветы ярко -красные до розового или апельсин. Плод представляет собой древесную урн в форме 20–42 мм (0,8–1,7 дюйма) длиной и шириной 18–30 мм (0,7–1,2 дюйма) с клапанами, заключенными в фрукты. [2][3][4][5]
The other two bloodwoods found in the south-west of Western Australia are C. haemotoxylon and marri (C. calophylla). Unlike C. ficifolia, they have tessellated bark rather than fibrous bark.
Taxonomy
[edit]Red-flowering gum was first formally described in 1860 by Ferdinand von Mueller, who gave it the name Eucalyptus ficifolia and published the description in his book, Fragmenta Phytographiae Australiae.[6][7] In 1995, Ken Hill and Lawrence Alexander Sidney Johnson changed the name to Corymbia ficifolia.[5][8]
In 2009, Parra-O and colleagues published a combined analysis of nuclear rDNA (ETS + ITS) and morphological characters published to clarify relationships within the genus Corymbia. C. ficifolia was shown to comprise a natural group with two other Western Australian species C. calophylla and C. haematoxylon. They classified the group as section Calophyllae within the subgenus Corymbia.[9]
The specific epithet ficifolia is from Latin ficus meaning 'fig' and folium 'leaf', referring to the similarity of its leaves to some species of Ficus.[7][10]
The type specimen was collected from around the Broke Inlet by George Maxwell.[2]
Distribution and habitat
[edit]Corymbia ficifolia grows in sandy soil in low forest on slopes and is restricted to a sub-coastal distribution south-east of Perth, east of Mount Frankland, Walpole and the Stirling Range.[2][11]
Use in horticulture
[edit]Red-flowering gum is one of the most widely cultivated of all eucalypts, both in Australia and overseas. It is best suited to temperate districts with low summer rainfall and is rarely reliable on the east coast of Australia. In suitable climates it is moderately fast-growing and is often larger and more vigorous in cultivation than in the wild. Eucalypts are difficult to grow from cuttings and are usually grown from seed. As a result, flower colour cannot be guaranteed, although some small forms have become available as grafted plants.[12]
In nature Corymbia ficifolia prefers infertile, sandy soils but it is readily adaptable to most temperate locations, provided it is not exposed to severe frost or sustained tropical damp. It is an ideal street tree as it is hardy, moderately fast growing, and rarely grows large enough to require pruning. The largest known single-stemmed tree of this species in the world (216.5 cm diameter) is located on Princes Street in Hamilton, New Zealand.[13] Because of its big and lovely colourful flowers, genetic improvement for cold resistance in Dublin area in Ireland is being carried out by collecting seeds in the coldest parts of Western and Southern Australia where it grows. In Ireland most of the plants were killed by severe frosts but the surviving shoots have been kept by tissue culture.[14]
