Specierum Crotalari:z hic descriptarum (excepta C. ramosissima) 
identitatem cum stirpibus Indicis probavit illustris Jos. Hooker 
(eonferatur Flora Tasman. Introduet. p. 43), et ipse confirmavi e 
collatione specierum homonymarum extra-australium in Museo 
Botanieo Melbournensi asservatarum.  Cognosco preter antece- 
dentes inter eas Australiam incolentes C. anthylloidem (Lam. Ene. 
Meth. ii. 195), quam e vicinia urbis Rockhampton a clar. Thozet 
accepi, et C. dissitifloram (Benth. in Miteh. Trop. Austr. p. 386), 
quam in montibus Hammersly Range legit Maitl. Brown, ad rivum 
Attack Creek J. Maced. Stuart, ad flumen Albert River Lands- 
borough et ipse reperi in variis locis Australis orientalis tropicz. 
Ab ultima specie vix specifice separanda videtur C. eremza (F. M. 
in Report on Greg. Plants from subcentr. Austr. p. 5 ; Pentady- 
namis incana, R. Br. in Sturt's Centr. Austr. ii. App. p. 76).
