Grevillea didymobotrya is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is an erect shrub with simple leaves, the size and shape depending on subspecies, and cylindrical groups of yellow or cream-coloured flowers.
Description
Grevillea didymobotrya is an erect shrub that typically grows to a height of Шаблон:Cvt. It has simple leaves, either linear, more or less cylindrical, Шаблон:Cvt long and Шаблон:Cvt wide, or mostly narrowly elliptic, Шаблон:Cvt long and Шаблон:Cvt wide, depending on subspecies. The flowers are arranged in cylindrical racemes Шаблон:Cvt long and are yellow, the pistil Шаблон:Cvt long and glabrous. Flowering occurs from May to October and the fruit is an elliptic to oval follicle Шаблон:Cvt long.[1][2]
Taxonomy
Grevillea didymobotrya by Carl Meissner in Prodromus Systematis Naturalis Regni Vegetabilis in 1856, from material collected by James Drummond in the Swan River Colony.[3][4] The specific epithet (didymobotrya) is derived from Ancient Greek words meaning "paired" and "bunch of grapes", referring to the racemes.[5]
In 1986, Donald McGillivray described two subspecies in his book, New Names in Grevillea (Proteaceae) and the names are accepted by the Australian Plant Census:
- Grevillea didymobotrya Meisn subsp. didymobotrya[6] has more or less cylindrical to linear leaves Шаблон:Cvt long and Шаблон:Cvt wide with up to seventeen longitudinal ridges, and bright yellow or cream-coloured flowers mostly from August to January;[7][8]
- Grevillea didymobotrya subsp. involuta McGill.[9] has mostly narrow elliptic to egg-shaped leaves with the narrower end towards the base, Шаблон:Cvt long and Шаблон:Cvt wide with up to eleven longitudinal ridges on the lower surface, and yellow flowers in August and September.[10][11]
Distribution and habitat
This species of grevillea grows in heath, shrubland or mallee on sandplains and is widespread from near Shark Bay to Cundeelee Balladonia and Ravensthorpe. Subspecies involuta has a more restricted distribution between Geraldton and Mullewa.[1][2][7][8][10][11]
Conservation status
Grevillea didymobotrya is listed as Least Concern on the IUCN Red List of Threatened Species.[12] Both subspecies of G. didymobotrya are listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.[2][8][11]
