Species browser problem

I tried to use the species browser in the aid of some spurge identifications.

After slowly working through the hierarchy to get to Euphorbia (it took time for iSpot to display all the thumbnails, especially for flowering plant orders) I ended up here


Note that even common species like E. peplus and E. helioscopia have no examples.

Compared to https://www.ispotnature.org/communities/uk-and-ireland/species-dictionary/NHMSYS0000458629/euphorbia
which does show large numbers of euphorbia observations
