This genus is here limited as in Bentham and Hooker’s ‘Genera Plantarum,’ the 
two other species proposed by Fournier being referred to Oplismenus—see O. holci- 
formis. Besides the following, there is one Brazilian species.

This genus is now spread over nearly all tropical and temperate regions, and many 
species have been proposed; but Bentham estimates that there are scarcely more than 
ten distinct ones. We have seen no authenticated specimens of Fournier’s Mexican 
new species; but there are a considerable number of forms in the Kew Herbarium 
referred to S. glauca, &c., which may represent some of them.
