I am trying to find out the name of this plant depicted on this guard - any ideas? My first thought was Arum but it doesn't look like plant images I can find.

Try Omodaka, Dale. https://en.wikipedia.org/wiki/Sagittaria_trifolia

Thanks Piers I had a look but not convinced, there are only single leaves on each stalk.

This one has the Sagittaria motif, not the same plant. Wish my father was still alive he was an expert on horticulture - it didn't rub off on me!

Spatterdock/Spadderdock?

lotus blossoms (leaves unfurling...)

Thanks Piers and George - I think you have put me on the right track. This is the closest image I could find that might fit the bill. 

Kahahone - a species of Japanese Water lily. I think the tsuba maker may have used a bit of artistic license.

Lovely illustration of Ko-hone' as it's called today. (Kawahone')

Piers the print is actually up for sale on eBay, https://www.ebay.ie/itm/Kono-Bairei-Kahahone-or-Japanese-water-lily-1889-Print-60x80cm-/273887944921

I also found a set of original books https://www.biblio.com/book/chigusa-hana-bairei-kono/d/1291086764  but the price is beyond me.

These seem to be modern prints, from the description below, Dale.  Wouldn't mind an original print though at that price.

 

As to the set, well, in another lifetime!!!
