Hi all,
with the plant i have running vertical ......... Its still the closest ive seen so far.
The leaf veins just means it is a "monocotyledon". <"L
eaf venation"> was how I was able to exclude plants like <"
Lesser Spearwort (Ranunculus flammula)">. All the possible ID's we've discussed are monocotyledons (
Sarurus is a <"
bit of a strange one"> and it is neither mono or dicot)
.
confirmed here (
Luronium natans | Online Atlas of the British and Irish Flora ), not that I had any doubt, then it's likely not that.
You really need a flower for a definitive ID, a lot of water plants look very similar, even in the UK.
......... The key feature for identification is the presence of stolons which, in the absence of flowers, is the only reliable diagnostic feature that separates it from Baldellia ranunculoides and Alisma plantago-aquatica........
I think that probably makes Water Plantain (
Alisma plantago-aquatica) the most likely identification.
Amazon Swords (
Echinodorus spp.) belong to the same family <"(
Alismataceae)"> as the Water Plantains, and your plant should have a similar white three petalled flower, but a lot smaller.
