The plant Victor has to draw (5)
I believe the answer is:
vetch
'the plant' is the definition.
(vetch is a kind of plant)
'victor has to draw' is the wordplay.
'victor' becomes 'v' (phonetic alphabet: alpha, bravo, charlie etc.).
'has' means one lot of letters go next to another.
'to draw' becomes 'etch' (I've seen this before).
'v'+'etch'='VETCH'
(Other definitions for vetch that I've seen before include "Wild climbing plant" , "Climbing plant of the pea family, cultivated as fodder" , "Leguminous plant" , "Weed" , "Tare" .)
