Grevillea angustiloba, commonly known as dissected holly-leaf grevillea,[1] is a species of flowering plant in the family Proteaceae and is endemic to southern continental Australia. It is a prostrate, low-lying or erect shrub with deeply divided pinnate leaves and usually red, sometimes orange or pale yellow flowers.
Description
Grevillea angustiloba is a prostrate to low-lying or erect shrub that grows up to Шаблон:Cvt high, Шаблон:Cvt wide and has hairy stems. The leaves are Шаблон:Cvt long and Шаблон:Cvt wide in outline, deeply divided, pinnate or bipinnate with up to thirty lobes, the end lobes mostly linear, Шаблон:Cvt long and Шаблон:Cvt wide. The flowers are arranged along an erect rachis Шаблон:Cvt long, and are red, sometimes orange or pale yellow, the pistil Шаблон:Cvt long, usually with a pink to red style. Flowering mainly occurs from February to March and the fruit is a follicle Шаблон:Cvt long.[2]
Taxonomy
Dissected holly-leaf grevillea was first formally described in 1868 by Ferdinand von Mueller, who gave it the name Grevillea ilicifolia var. angustiloba in his Fragmenta Phytographiae Australiae.[3][4]
In 2004, Trisha L. Downing, Marco Duretto and Pauline Ladiges raised the variety to species status as G. angustiloba and described two subspecies in Australian Systematic Botany, and the names of the subspecies are accepted by the Australian Plant Census:
- G. angustiloba (F.Muell.) Downing subsp. angustiloba[5] has leaf lobes Шаблон:Cvt wide;[6]
- G. angustiloba subsp. wirregaensis Downing[7] has leaf lobes mostly Шаблон:Cvt wide.[8]
Distribution and habitat
Grevillea angustiloba grows in mallee scrub, heath and Melaleuca uncinata communities mainly in the Little Desert region of western Victoria and in south-eastern South Australia.[1][2][9]
Conservation status
Grevillea angustiloba is listed as Critically Endangered on the IUCN Red List of Threatened Species. It has a severely restricted distribution, a small population exceeding no more than 250 mature individuals and a projected population reduction of greater than 25% within the next generational length of 30-50 years. The main threats to this species include land clearing for agriculture, salinization and droughts.[10]
