Plant found in Manila (4)

I believe the answer is:

anil

I'm a little stuck... Click here to teach me more about this clue!

'plant found in manila' is the definition.
'anil' can be an answer for 'plant' (I've seen this before). I am not certain of the 'found in manila' bit.

'in manila' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ANIL' is hidden in the letters of 'manila'.

Can you help me to learn more?

(Other definitions for anil that I've seen before include "A blue dye" , "Colouring" , "Indigo (plant or dye)" , "Indian man" , "name of man" .)

I've seen this clue in The Times.
