The only thing I can add is that
Katipunan generals were the ones who used the flower and vines design, to signify their rank. Thus it wouldn't be far-fetched to think that they also used the same motif in their personal weapons and accessories.
Alternatively, if the former owner of the sword was not a
Katipunan general, then in all likelihoo he was a civilian VIP.
In other words, it's a very cool sword in any case!
