referred to Cryptocarpus. There is some confusion between these two genera; and we 
are unable to clear it up satisfactorily. If Cryptocarpus globosus, H. B. K., be really 
the same as Boldoa ovatifolia, Lag., and B. purpurascens, Cav., as we suspect, the genus 
Cryptocarpus should be reduced to Boldoa, and Salpianthus, H. B. K., would stand as 
a genus and include Boldoa lanceolata, Lag.
