J. H. MAIDEN. 



The differences between A, feroeior and A. ulicina appear 

 to be as follows. A. ulicina has longer, more subulate 

 phyllodes, those of A. feroeior are club-shaped to falcate* 

 A, ulicina has 25 flowers in the head, calyx irregularly 

 lobed and more hairy; A. feroeior 7 in the head with a 

 truncate calyx. 



2. With A. oxyclada F.v.M. The two species are very 

 different in habit and phyllodes, but have resemblance in 

 the few (7) flowers in the head, in the morphology of the 

 flowers, including the bracts. 



In order to make the statements concerning these three 

 species clear, it is necessary, in addition to the enclosed 

 table, to give some detail drawings. See the Plates. 



OXYCLADA. 



Branches termin- 

 ated by fine thorns 



Phyllodia. 



Linear, short, 

 hardly striate. 

 Symmetrically 

 mucronate. 

 Terminal gland 



Flowers. 



7 in the head, 

 Petals free, 

 smooth, small 

 calyx with rag- 

 ged lobed edges. 

 Ovary smooth. 

 Foliaceous bracts 



Pods. 



Moniliform. 

 Seeds globose, 

 ridged and with 

 an arillus cover 

 ing one side. 



SPINOSISSIMA 



( leptacantha) 



" Smaller than 

 ulicina, and differs 

 also in its rect- 

 angularly spread 

 ing branches" of 

 that species. 



(Pritzel). 



Linear, not striate, 

 obliquely mucro- 

 nate. 



20 in the head. 

 Petals smooth, 

 free. Very small 

 calyx with an in- 

 flated appearance, 

 ragged edge. Ovary 

 smooth. No Jloral 

 bracts found. 



Moniliform'. Seeds 

 too immature to 

 draw or describe. 



Rigid spreading 

 shrub. 



Linear, striate, 

 obliquely mucro- 

 nate. 



20 in the head. 

 Petals smooth, 

 divided half way 

 down, calyx ir- 

 regularly lobed, 

 ciliate. Ovary 

 smooth. Large 



coarse floral 



bracts. 



Moniliform, with 

 globular seeds 

 with a marked 

 ridge opposite 

 the arillus. 



FEROCIOR. 



A shrub more 

 strongly resembl- 

 ing J] lex than does 

 A. ulicina. 



Flattened club- 

 shaped, not stri- 

 ate, I main nerve, 

 obliquely mucro- 

 nate, gland a little 

 way up from base. 



7 in the head, 

 petals free, 4 or 5. 

 Calyx turbinate 

 with irregular 

 edge, shortly cili- 

 ate. Large bract 

 apparently en- 

 closing the flower 

 head. Ovary 

 smooth. 



Not seen.
