My lucky day? (This isn’t what you think!)

Maybe, but this is not a four-leaf clover (aka “Trifolium repens,” indicating, of course, that the usual arrangement is three leaves).

This isn't even a clover, per se. Rather, this is actually a fern, Australian water-clover (“Marsilea mutica”), and the leaves are called fronds! A fern? you ask? It reproduces by spores! So this plant is in the Marsileaceae family, which is, from wikipedia, “a small family of heterosporous aquatic and semi-aquatic ferns.”

From wikipedia, https://en.wikipedia.org/wiki/Marsilea » “The name honours Italian naturalist Luigi Ferdinando Marsigli (1656–1730).

“These small plants are of unusual appearance and do not resemble common ferns. Common names include water clover and four-leaf clover because the long-stalked leaves have four clover-like lobes and are either held above water or submerged.”

Compare this to Trifolium repens with a "lucky" four-leafed mutant, http://phytoimages.siu.edu/imgs/paraman1/r/Fabaceae_Trifolium_repens_21246.html
