Grevillea tetragonoloba 'Ray's Red' is a 2016 University of California Santa Cruz Arboretum Koala Blooms Australian Plant Introduction. It was originally received by the arboretum in 1977 as Grevillea tetragonoloba 77.73 and its name honors the late natural history professor Ray Collett (1933-2012), the founding director of UCSC Arboretum. This form is possibly the same as what was once sold in Australia incorrectly as fine leafed form of G.hookeriana and this species is thought to be one of the parents of Grevillea 'Red Hooks'. The genus name Grevillea honors after Charles Francis Greville (1749-1809), a patron of botany, a very close friend of Sir Joseph Banks, and president of the Royal Society of London. The specific epithet is from the Greek words 'tetra' meaning "four" and 'gonia' meaning "an angle" combined with the Latin word 'lobus' meaning "a lobe" in reference to the cross-sectional shape of the leaf lobes.  This information about Grevillea tetragonoloba 'Ray's Red' displayed is based on research conducted in our library and from reliable online resources. We will also note observations that we have made about it as it grows in the gardens in our nursery and those elsewhere, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others, and we welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing it.     [MORE INFO]
