Sagina x normaniana   Scottish Pearlwort RRR DDD N

Sagina x normaniana

There are two "common" pearlworts in the Ben Lawers Corrie and they are quite similar at first glance. This one is a hybrid between Sagina procumbens (Procumbent Pearlwort) which is an extremely common lowland weed of paths and gardens and Sagina saginoides (Alpine Pearlwort) which also grows in the Corrie. I haven't seen the lowland plant ever in this upland Corrie.

The difference between the two is that the Scottish Pearlwort (Sagina x normaniana) roots at the nodes and checking this one plus a few others around it showed they all were firmly rooted at nodes. The white flowers are the Pearlwort in the photo.

Sagina x normaniana is a plant of the mountains around mid Perthshire in Scotland where it is found on several hills. It does not not occur in England. Wales or Ireland or elsewhere in Scotland.
