Sundry IDs for checking / confirmation

[poschiavanus]

A variety of plants I've noticed over the past couple of weeks where my ID is provisional/tentative/absent:

1. Yellow-flowered crucifer, growing in a local ruderal patch where I keep finding new plants for the site. Flower is 6-10 mm diameter. Pods are squarish in cross-section. Basal leaves are quite fleshy. So far I'm inclined towards Treacle Mustard Erysimum cheiranthoides, but I'm not sure that it shows all the characteristics.

.

2. Persicaria sp. Can't make my mind up as to whether this is Red-leg P. maculosa or Tasteless Water Pepper P. mitis. Most of the plants I've found are somewhat past their best, so there's not a huge amount to go on the inflorescence. Red-leg is supposed to have densely fringed ochrae, whereas Tasteless Water Pepper has fewer and longer ciliae.



3. Rosette of grass-like leaves with white mid-rib. I'm pretty sure this is Goat's-beard Tragopogon pratensis. I found one rosette and remember seeing a lead in Poland and Clements Vegetative Flora with similar characteristics, and shortly after I found several more close by where I've regularly seen Goat's-beard in flower.



4. Shrub, with (presumably) evergreen leaves and berries. I'm sure I've seen this frequently in plantings before, but can't put a name to it.




5. Low-growing shrub with flowers in 'umbels'. Now in fruit with each flower head containing 5 nutlets. I'm pretty sure this is a garden Spiraea, but which one? It appears to have 'escaped' from the grounds of a local nursery and is spreading into a patch that the council landscaped a couple of years ago which is now getting covered by Bindweed, brambles, and Ivy-leaved toadflax.



6. Dwarf Mallow Malva neglecta (?). Another one from local ruderal patch.



Thanks in advance for any suggestions, corrections, etc.

1. Not sure of this either!
2. I would plump for Redleg, where yours is growing.
3. Goats beard.
4. An Elaeagnus
5. Not like my 2 spireas.
6. Dwarf mallow

1. I think Treacle Mustard - Erysimum cherianthoides is very likely. Seed-pods are round but with four wings, so could look square. Stems should also slightly square'ish.
2. is Redleg - Persicaria maculosa. Can just detect a dark patch on the leaf. (Flowers on Tasteless Water-pepper are much tighter to the usually drooping stem and are a brighter-pink/red).
3. Yes, I think Goat's-beard is most likely.
4. Portugal Laurel - Prunus lusitanica.
5. I recognise it but can't get a name. I don't think it's a Spirea.
6. Yes, Dwarf Mallow - Malva neglecta.

Thanks to you both.

1. The stem did not seem to be square in cross-section, but as this area now gets cut and this and many of the other plants are re-growing from rosettes. Lots look atypical. I can't see the medifixed hairs described in Poland and Clements, but I suspect finding that I really need to look at a leaf through the microscope not just with a hand lens. Anyway its not one of the Sisymbrium spp. which have given me trouble in the past.

2. Agree with habitat and dark-patch on leaf. I'd thought to find a classic Red-leg plant for comparison, but none were available.

4. I'll let you fight that one out! Personally, I'd favour Portuguese Laurel as I'd got it down as rose family, but the jizz is much further from Cherry Laurel than I'd imagined from the descriptions I've read.

5. It seems familiar to me too, I'm sure it's a pretty common garden plant. Closest I could get with available works was Spiraea media, although not everything matches. There are several other genera of Rosaceae which seem to have similar nutlets.

1 looks as though it could be Annual Wall Rocket, Diplotaxis muralis.
