An important character in Leptospermums is whether they keep their seed cases or not for a number of years, and the shape and hairiness of the seed cases. A diagnostic that distinguishes laevigatum from all other Leptospermums is that the seed cases have 6-11 radial slits in the tops, while the rest always have 5. So if you can find them, it is a good idea to take a photo from top and side of a seed case, and add a comment like ‘Seed cases not found’ if you can’t.
