Help appreciated with the parsing of these...
17a - I’m going to hide money split from sum (5)
The first 3 letters could be "sum" but that's all I can see.
47a - Country woman is shifting special plants (5)
"Shifting special" in the answer could lead to a 3 letter "woman", but the remainder doesn't lead to a "country" nor does it lead to a "country woman", at least as far as I can see.
I have the definitions for both and am sure of my answers but it's the wordplay that eludes me.
Thanks
