principalibus, uno nervo inferiore margini approximate et in 

 mucronem acutem terminante, altero e basi phyllodise in marginem 

 dorsalem terminante; nervis minoribus ex nervis principalibus 

 provenientibus; floribus in capitulis solitariis, axillaribus, globosis, 

 pedunculis filiformibus 1 - 1*5 cm. longis; calyce profunde lobato, 

 hirsuto, corolla ca. triplo sequilongo; petalis partim disjunctis, 

 glabris; pistillo longo, laeve; legumine seminibusque non visis. 



A spinous glaucous shrub of two and a half feet. Phyllodes 

 sub-triangular to irregularly trapeziform, about 7 mm. long 

 and about as wide at the top; the phyllodes largely replaced 

 by thin, flexible brown stipular spines up to 1 cm. long. 

 The phyllodes have usually two main nerves, one nearly 

 following the lower straight margin, and terminating in a 

 sharp mucrone, while from the base of the phyllode usually 

 springs a second thinner nerve terminating in the dorsal 

 margin. From both nerves some smaller nerves proceed. 



Flowers in single axillary globular heads, about thirty in 

 the head, on filiform peduncles of 1-1*5 cm. Flowers 

 5-merous ; calyx deeply lobed and hairy, about a third as 

 long as the corolla. Petals divided part of the way down; 

 glabrous. Pistil long and smooth. Pod and seeds not seen.

 1891, Elder Exploring Expedition (R. Helms). 



Named in honour of Dr. Alfred Barton Rendle, f.r.s.,
