Looks like it's a tree without leafs. The trunk seems to be the 6&9 on the bottom row.

I've been testing different solutions with the same idea in mind as Teesea: bare tree. Maybe a few leaf-like clusters separate from the tree?

R10c2, r11c1,3,18, r12c2,3,17,18,19, r13c18, r16c3,5,14, r17c6,9,10,12,15 that gives you the two isolated leaves and the base of the tree, the tree has four branches, two to the left, two to the right.

Yeah. This is hell to solve. Ill leave some hints that should hopefully make it a bit easier for others, in addition to Not A Conspiracy's (All of their hints are indeed correct).

r1c6, r2c7, r3c8,14 r4c1,8,13 r5c2,3,7,14.

Thank you for the hints Not_a_conspiracy & Mudmage52!

Thank you.

Thank you for the hints.

Wow! This was tough!!!
Thanks for the hints - I would NEVER have worked this out.

Thanks for all of the hints, I wouldn't have managed without them.

Yes thank you for the hints - I could not have 'solved' it without them.
