Long street missing both ends, where one may find cones (4,4)

I believe the answer is:

pine tree

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

'missing both ends where one may find cones' is the definition.
I can't judge whether this defines the answer.

'long street' is the wordplay.
'long' becomes 'pine' (to pine for someone is to long for them).
'street' becomes 'tree' (I can't justify this - if you can you should believe this answer much more).
'pine'+'tree'='PINE-TREE'

Can you help me to learn more?

(Another definition for pine tree that I've seen is " Evergreen conifer".)

I've seen this clue in The Telegraph.
