Here’s the top 5 most interesting finds, as described by Dave Bishop.
Creeping Yellow-cress (Rorippa sylvestris). This a native member of the Cabbage Family (Brassicaceae). Curiously, I’ve only ever seen it in rose beds in parks (!) This one was no exception (is it something to do with where the Council gets its rose bed mulches, I wonder?).
Broad-leaved Helleborine (Epipactis helleborine). This a native orchid species. It seems to be more common now than it was 25 years ago, when I first spotted it near Sale Water Park. Nevertheless, I was a bit surprised to find it in Alexandra Park! It tends to be the last orchid species of the year to flower (ours, though, were over and the plants were in fruit).
Few-flowered Garlic (Allium paradoxum). This is another introduced plant – this time from the Caucasus. I have only seen it once before (in Chorlton). I don’t think it’s particularly rare but it doesn’t seem to occur in many of the places where I regularly botanise.
Floating(?) Sweet-grass (Glyceria fluitans(?)). This is a native grass species of mud and shallow water. I’m fairly certain that it was G. fluitans but we found it quite late in the day and it needs more checking (there are other species of Glyceria that it could be). It’s presence suggests that the area over by Claremont Road, where we found it, may be much damper than I was expecting.
The full list of plants found will be posted shortly
