Species priori valde affinis differt habitu majore, floribus 
majoribus subsessilibus nec pedicellatis, calycis sub anthesi 
latioris dentibus longioribus, petalis inclusis et capsule forma. 
Petala nunquam tridentata, 
Syn. §S. coarctata, Lag. (vide Willk., Prodr. Fl. Hisp., suppl., 
p. 279 [1893}). 
In this plant the petals are invariably bifid: for this reason Salzmann’s 
later name has been substituted for Desfontaines’s erroneous and inaccurate 
name of “S. tridentata.”’
