21 across "Blue Spiraea almost wholly pruned" (4) .A.E
64 across ""Long ridge at end of the river" (5) .S.E.
Thank you so much!

64a ESK (theme) + (th)E + R(iver) = Esker

[elliemay1]

21 seen as saxe

[Moorea7]

6a Looks like Amman but ?

[JJ109]

Omlah and amban fit the letters but I can't parse either
OM lah includes a river but "hal" means nothing to me

[elliemay1]

Amman is the answer given on some Crossword solvers

[Lie-in King]

If I may?

Amman (alt "amtman"; official) - 'Nam(ibia) ma (relative)' (back)

[elliemay1]

I was hoping you would see this L-iK! How does saxe parse please?

[JJ109]

Many thanks L-I-K - I had seen the backwards parsing, but just not the fact that it was an official!

[JJ109]

S(piraea almost wholly Pruned) + unclued river AXE = Saxe (blue)

[Lie-in King]

Ta jj - only just back to the thread, so missed elliemay's post. I'm not bothering with the puzzle, far too much faffery for my liking...

[elliemay1]

Thank you L-i K and jj
