 Benth. Fl. Austr. i. 406. Glabrous, usually much branched at the base, with 

 stout decumbent or ascending branches of about ^ft., but sometimes lengthening 

 to 1ft. or more. Leaves from obovate to oblong, usually very obtuse, rather 

 thick, and ^ to fin. long, but in luxuriant stems lengthening out to lin. or more

Although Labillardiere confounded this species with S. spathulata, and represented and 

 described the fruit of the latter species, yet the common one, of which he described the 

 flowering specimens, has been so universally known under his name that it would only increase 

 the confusion to adopt a later name for that species. Among its numerous forms, the luxuriant 

 specimens with more conical spikes which commonly pass for the true S. mmiogyna, and the 

 smaller ones with fewer flowers and the young spike more obtuse, published by Lindley as S. 

 obtusa, pass into each other by innumerable gradations. It is to the former that Sehleohlendal
