There are no reasons given for changing this siting from Trifolium pratense to T. fragiferum.
However there are a number of observations that make it unlikely that these plants are T. fragiferum:
1. Individual plants have an erect growth habit; T. fragiferum is commonly decumbent. 2. Most definitively, the mature flower heads do not have the expanded, vesicular calyx tube that give it the strawberry (Fragiferum)- like appearance.
I think the original designation as Trifolium pratense (Red clover) is correct.
Hi Walter, yes you were correct originally sorry about that, doing to many IDs late at night leads to you mixing things up at times. It isn't T.fragiferum for the reasons you outline, plus the leaf shape is that of T.pratense. Its an interesting record of a rather striking clover.
Thank you. I haven't noticed this clover species in this area before. I wonder if this wet spring and summer season has germinated some hard seeds that have been in the soil for a long while ?
