Topic: Germinants with 4 cotyledons - does it mean something?

The fact that both seedlings has extra cotyledons actually supports the possibility that this may be due to mutation. Because once a mutation appears, it becomes heritable. Thus very probably the parent plant/s were the original mutants, or themselves the the offspring of mutants. If the mutation is...

Although the norm is one (monocots) or two (dicots) cotyledons, there are anumber of cases where extra cotyledons are present; It is probably a mutation (in your case - since both seedlings have extra cotyledons. I have often seen Ranunculus species with 3 cotyledons

Most probably a feral Pyrus communis. But rosaceous trees are notoriously difficult, especially due to widespread hybridisation and the presence of numerous cultivars and hybrids between cultivars are are often found growing in a feral state.

It is Holoschoenus. This is a very variable species with numerous described varieties. The var. globiferus is actually uncommon. It has smaller heads which are very numerous and the closest i've seen are plants at Migra l-Ferha.

I have examined the photos more closely and notice that some of the florets have a short awn (not present in Poa). If the plant is rather large (Poa annua is a small annual) and spikelets are about 1 cm (less than 5mm in Poa) than it most probably Schedonorus arundinaceus (= Lolium arundinaceum; for...

It is not a hybrid since local Opc seem unable to cross-fertilise. However there are such things as somatic mutations which occasionally arise in clonal populations. Then remember that we have two distinct clones of Opc: the normal one and the flore pleno variety. Where they imported separately?

Such variants do occasionally arise in Oxalis pes-caprae. It would be interesting to cultivate such variants to see if the same happens the following year. That would establish whether the variant is genetic or due to some stress being suffered by the individual plant[/i]

I did some homework. The plant is H. hirsuta (sepals with distinct arista at the apex) but plants which are hairier, appearing greyish are sometimes distinguished as H. cinerea. Both forms occur in the Maltese Islands. Most authors consider H. cinerea as just a variant of H. hirsuta. The sub-family ...

The stuff accompanying the sedum is a species of Nostoc (possibly N. commune) which is a cyanobacterium (=blue-green alga) which forms large gelatinous colonies. Some say it edible but i have not yet tried it out.
