"Recently, plants seen of Ononis do not fit the description in Stace (2019) for O. repens (on right) and not fully for O. spinosa (below left) even if using Sell & Murrell where O. repens is treated within the subspecies of O. spinosa.
"Whether these are hybrids or not is debatable. In relation to the two taxa and putative hybrids, I would be interested in material (fresh) to have a look at in detail, including some anatomical aspects as they are given as two different chromosome numbers in Stace (2019) and looking at aspects such as stomata it might help decide what the two taxa are and or putative hybrids.
"It may be a bit late to start doing this but I will pick it up next year and hopefully see more material from different areas.
"Meanwhile, if you have one or both (or putative hybrids) I would be interested to see some material for a preliminary look at these taxa. Email me at Michaelpw22@hotmail.com for details of where to send your specimens".
