a close cousin to...

I wandered gaily through the dawn
That filtered down between the trees
As though towards the lakeside drawn
That rippled on to greater seas
And, as I stepped down to the shore
Encountered that not spied before

For there upon the verdant sward
A bunch of nettles proud and high
Of poisoned itching jewels, a hoard,
Those stings stretched up towards the sky
And in the very midst of these
I stood enfolded to the knees

So now upon my bed I lie
and swiftly ply the soothing Dock
The leaf, its charm, the pains belie
I rose again ere chimed the clock
With scythe in hand, on brow a frown
I chopped those bl***y nettles down!
