Daisy, cow, internally cross with attention (5)

I believe the answer is:
oxeye
'daisy' is the definition.
(I've seen this before)
'cow internally cross with attention' is the wordplay.
'internally' indicates the central letters.
'cross with' becomes 'x' (X is cross-shaped. I am not sure about the 'with' bit.).
'attention' becomes 'eye' (eye is a kind of attention).
The middle letter of 'cow' is 'o'.
'o'+'x'+'eye'='OXEYE'
Can you help me to learn more?
(Other definitions for oxeye that I've seen before include "Daisy plant" , "Type of daisy" , "Flowering herb" , "Wild chrysanthemum" , "Kind of daisy" .)
