BOTANY The only widely or moderately distributed British forms still undis- covered in Sussex are R. Rogersii, R. nitidus, R. villicaulis (type), R. Sehneri, R. grains, R. silvaticus, R. mucronatus, R. iiifestus, R. scaber, R. infecundus and R. viridis. Most of these, together with a few rarer unrecorded species, will probably yet be found in some of the unexplored parts of the county. 69
