Answer: I'm sorry if I get this wrong but I think it is Alliteration and internal Rhyme
Explanation: It would make sense because alliteration repetition and it is saying " light shade for the leaves when laid" and as you can see they have more than 2 words that begin with L. Then I think that it is Internal Rhyme because it is involving a word in the middle of this line.
(again I'm Truly sorry if I got this wrong)
