Equal-leaved knotgrass (Polygonum arenastrum)

Family: Polygonaceae

Common name: Equal-leaved knotgrass

Scientific name: Polygonum arenastrum

Date taken: 28/8/2022

Notes: Differs from Knotgrass (Polygonum aviculare) in having equally sized leaves on flowering and non-flowering branches. Sources also mention the fact that lobes of tepals fuse more (>1/3) in this species, but personally I found that difficult to observe and judge.
