My Lasia spinosa flowered this season, a rather strange flower/inflorescence. Very thin with a twirl. A bit hard to see in this photo, it's not very photogenic. It's almost black.
But I don't think it's produced any viable seed. The spent flower stalks have what look like seed/berries, but they seem too small. It's just that the stalks haven't withered yet, after a couple of months since the flowers withered. Maybe a couple of months more and I'll know for sure.
