This species is recognised as 'Rare' in J.D.Briggs & J.H.Leigh, Rare or Threatened Australian Plants (1995).
Grevillea adenotricha is a distinctive species, characterised by the leaves with many evenly distributed marginal teeth, the very short pistil, and the dense indumentum of gland-tipped simple hairs occurring on most vegetative parts. This species also has the seed ellipsoidal with a recurved margin bearing a pale wavy rim, and on this feature is likely to be more closely related to G. longicuspis than to other members of this group.
