gine ciliato vel granulato, petalis ca. dimidio aequilongo. Petalis

A numerously branched, probably dwarf shrub, largely 

 covered with a very short tomentum, and, particularly the 

 young shoots, exuding a gummy substance. 



Phyllodia numerous, linear-terete, with two not very 

 marked sunk nerves, slightly curved, recurved at the point 

 in a slightly rostrate manner, 1 cm. long. 



Stipules deciduous and rarely found. They have the 

 similitude of minute thorns, one on each side of the phyllode 

 attachment, and are embedded in a gummy secretion. 



Peduncles singly or in pairs, about 8 mm. long, bearing 

 each a small globular head of about twenty flowers mostly 

 5-merous. Bract capitate. Oalyx deeply lobed, attached 

 about half-way up, ciliate or granular at the edges, about 

 half as long as the petals. Petals glabrous except at the 

 tips. Ovary hoary or with fine tomentum. Style very 

 long. 



The type is from Camp 42, Elder Expedition (R. Helms). 



Range. 

 We only know it from Western Australia, and from 

 Camps 42 and 54 of the Elder Expedition. These were in 

 the Victoria Desert (R. Helms, No. 12). Labelled A. 

 Bynoeana Benth. by Tate. The position of Oamp 43, reached 

 on the following day, was Lat. 27° 36' 10", and say Long. 

 126° 40'. Camp 54, 17th September, 1891. Victoria 

 Desert (R. Helms, No. 12). Camp 54 was in Lat. 29° 33' 25" 

 and in Long* 124° 30'. Camp 54 is placed in the leader's 

 journal under 18th September, and there is often this dis- 

 crepancy (easily accounted for) between the numbers of 

 the camps and dates, as entered in the journal and her- 

 barium labels. Evidently they were in botanically very
