Описание
[ редактировать ]Grevillea Buxifolia - это прямое распространение кустарника, который обычно вырос до высоты 0,5–2 м (1 фут 8 дюймов - 6 футов 7 дюймов). Листья имеют яичную, узко продолговатые до эллиптических, длиной 7–35 мм (0,28–1,38 дюйма) и шириной 2,0–8,5 мм (0,079–0,335 дюйма), с краями, выведенными или свернуты под. Цветы расположены в скоплениях на концах ветвей и покрыты шерстяными, ржавыми до оленями и беловатыми волосками, плислая 11–21 мм (0,43–0,83 дюйма). Цветение в основном происходит от весны до осени, а фрукты обычно являются волосатым, овальным фолликулом 18–22 мм (0,71–0,87 дюйма). [ 3 ] [ 4 ]
Таксономия
[ редактировать ]This species was first formally described in 1794 by James Edward Smith who gave it the name Embothrium boxifolium in his A Specimen of the Botany of New Holland.[5][6] In 1810, Robert Brown changed the name to Grevillea buxifolia in Transactions of the Linnean Society of London.[7] The specific epithet (buxifolia) means "box-tree-leaved".[8]
The names of two subspecies of G. buxifolia are accepted by the Australian Plant Census:
- Grevillea buxifolia (Sm.) R.Br. subsp. buxifolia[9] has a conspicuous appendage usually 2–4 mm (0.079–0.157 in) long on the style;[10][11]
- Grevillea buxifolia subsp. ecorniculata Olde & Marriott[12] usually lacks a style appendage, but if present, it is less than 1.3 mm (0.051 in) long.[13][14]
Distribution and habitat
[edit]Grey spider flower grows in woodland or heath in New South Wales, on the South Coast, Central Coast and inland to near Pigeon House Mountain west of Ulladulla.[3][4][15] Subspecies ecorniculata is restricted to the area between Putty, Gospers Mountain and Wollombi north-west of Sydney.[13][14]
Conservation status
[edit]Despite its relatively limited distribution, Grevillea buxifolia is listed as Least Concern on the IUCN Red List of Threatened Species, as it is locally common, its population is presumed to be stable, it occurs within protected areas and there are no major threats currently affecting it. The main threat to this species is inappropriate fire regimes, meaning an increased frequency in bushfires.[1]
