Looks like a hybrid of G. baueri and G. rosmarinifolia known as 'John Evans'. Supposedly Berrima is the source of that cultivar. There's a view that G. rosmarinifolia is not indigenous to that area. It has been planted around Penrose and has naturalised.

There is no drop-down menu option for this hybrid. If the Council admins would like to add it to the list, I can then confirm it as this hybrid.

Ummmm, I'm not sure what our policy on artifical hybrids is, but personally I don't think they should be included in our database. I think Grevillea sp is fine in this context.

Okay, well I changed the name to reflect this, I think this case may be an exception since it is a naturally occurring hybrid (at least here).

That does depend on your definition of "naturally occuring". Given this is an artifical hybrid it will have been planted here at some stage. There are a myriad of cultivars which are appear as part of landscape plantings (including in many nature reserves), which we haven't included within naturemapr taxonomy at present. Maintaining hybrids of any kind can be pretty controversial, so historically we have only done it if they have been formally described and are naturally occuring (note this does not mean naturalised). Chiloglottis x pescottiana is a good example. Hybrid ID gets pretty messy pretty quickly, especially in a genus which is popular with growers such as grevillea. I think all of this is generally best avoided, which means that in cases such as this one even though we know the identity of the hybrid a genus level ID is sufficent.

I reckon that there is educational value in recognising hybrids in NatureMapr, even if artificial. Some threatened species are at risk in part from genetic swamping through natural or artificial hybrids.
This isn’t the same as recognising cultivars that just selected forms.
It’s useful to get some attention onto this particular hybrid so that Council might learn whether it should invest in removing them and and G. rosmarinifolia in that area. G. baueri is an R ROTAP and the Berrima population is extensively hybridised.
