968. JusTicA Necker, Justicia ! L. auct. 

 Adatoda Tourn. Ad. &c. The tropical regions 

 swarm with plants referable to this group, rath- 

 er than Genus. Linneus had 37 sp. with Dian- 

 thera, Persoon had 100 in 8 sections, each real 

 Genera. Vahl and Vitman had 117 and now 

 we know nearly 200. Dianthera was improper- 

 ly united by some botanists ; but Necker had 2 

 detached G. Geunsia and Roslinia; he properly 

 stated that Justicia like Yeritas or Prudentia 

 could not be generic names without modifica- 

 tions. Few Genera offered so many distinct 

 characters for good Genera, as stated by R. 

 Brown, 40 such will be afforded when all the 

 sp. will be well revised: meantime Crossandra, 

 Apelandra, and Elytraria have been separated.
