Description

Grevillea dimidiata is a single stemmed plant that typically grows to a height of 2 to 6 metres (7 to 20 ft) and as high as 12 metres (39 ft). It has simple leaves to a length of 9 to 22 centimetres (4 to 9 in) and a width of 3 to 5.5 cm (1.2 to 2.2 in).

It produces a white-cream inflorescence at end of the branch from May to October.[1] Lens shaped smooth or wrinkled fruit are then produced which are 16 to 23 mm (0.63 to 0.91 in) long.[1] It will produce seeds after 4 or 5 years of age.[3]

The plant has a typical lifespan of 11 to 20 years and is well adapted to fires in its environment. Adult plants will undergo epicormic resprouting after a fire.[3]

Distribution

It is native to the Kimberley region of Western Australia, and in the Northern Territory.[1] It is found in scrubland or grassland habitats, and grows in rocky or sandy soils and on rocky outcrops.[1]

gollark: GTech operates a number of trilaterators, but they can only listen on known-in-advance channels because of the 128 channel limitation.
gollark: Of course, I think we really need 12 sniffers, 4 per dimension, so we can get good trilateration fixes.
gollark: * make 512 modems listen on 128 channels each
gollark: It's just a regular rednet one, not modem, right?
