Both are Eucalyptus conferruminata. This is much more commonly planted than both E. sinuosa and E. lehmannii and differs from both in being a non-lignotuberous tree (an obligate seeder) rather than mallees.

Two big issues with the new BOM site, for anyone working in the field:

The 'Current Observations' table, where you could see and compare current observations (wind gusts, temps etc) across the state, is no more.

Rain radar maps are dumbed-down so it is difficult to locate on-ground locations.

1. Eucalyptus conferruminata subsp. 'Cape Arid' (Cape Arid marlock)
2. E. dolichorhyncha (long-budded fuchsia gum)
3. E. diversifolia subsp. hesperia (Wylie Scarp mallee)
4. E. rhodantha (rose mallee)

A great initiative by Ian Roberts, showcasing many of the eucalypt species he has planted around Blyth.

Unfortunately I can’t be there for the opening (I’ll be many thousands of kilometers away on that date) but it should be a wonderful day for all that make it.

The buds/flowers/fruits begin on a thin twig, but as the branch gets thicker over time (due to secondary growth), the wood envelops the peduncles (the group stalk of the buds/fruits). This can happen relatively quickly (a year or two) in fast-growing plants.

Haha… well you’ve got me started! Lemon-scented gum has now been placed back into Eucalyptus by some (including me) in response to some other taxonomists splitting it into a new genus, Blakella, in 2024.

The euc flowers are Eucalyptus leucoxylon, known as yellow gum in Victoria and South Australian blue gum in SA.

Not that I’m aware. There’s so much drought dieback in southern SA at the moment though, so someone might be measuring this somewhere?
