Table 1 Summary of key vegetative and inflorescence characters used to differentiate species in the S. cuspidatus group. Dimensions are listed in mm and include 25 th and 75 th quartile values. Minimum and maximum values are given in brackets for cases where they are sufficiently different than quartile values. More detailed descriptions of characters are given under the circumscription for each species.
