When I was in the field I thought they didn't, only when I looked on the computer monitor does it look like they are part of the same plant. I used the PlantNET descriptions and considered the leaves to be oblanceolate which matched both W. stricta and W. communis. I relied on the stem leaves and relative lengths of sepals to the corolla tubes and lobes to separate the species. Did I get it wrong? I've not bothered too much with this genus in the past, too hard to photograph well as the flowers only seem to open when the wind is up and the flies are about.
