The National Library of Australia also has this sheet music, but this arrangement only has lyrics for the chorus, not the verses:

ONLY A LEAF
"Arranged by John Crook on the famous melodies by J. Slater & T. B. Fayme."

Melbourne: Allan & Co., [190-]

Only a leaf, ah! but what grief it caused in the dim long ago.
Once it was red; now faded and dead and the woman that wore it laid low.
It was worn by a beautiful angel who should have been my wife,
Only the leaf of a rosebud, but it changed the whole course of my life.
