186 J. H. MAIDEN. 



2. With A, juncifolia Benth. In this species the phyllodes 

 are up to 17 cm. in length, with a midrib, and with a bend 

 about naif an inch from the base, and subtended by a gland. 

 The lobes of the calyx are divided to the base, and their 

 edges are ragged. Ovary smooth and shiny. Very small 

 arillus. There are other differences between this and A. 

 Havilandi. 



3. With A. Menzelii J. M. Black. Its affinities are less 

 close. 



Calamiformes (Uninerves). 

 A. tenuior, n. sp. 



Frutex probabiliter. Phyllodiis linearibus subulatis paullo 

 planatis 13-14 cm longis, costis vel nervis numerosis prominen- 

 tibus, apice in acumen molle, angustato, breviter villosis. Stipulis 

 brevibus, latis, breviter ac dense villosis. Pedunculis solitariis 

 vel geminis, 1-1*5 cm. longis, gracilissimis, villosis, capitulis 

 majusculis globosis 24-30 floris, plerumque 5-meris. Sepalis 

 spathulatis, villosis, corollye climidium aequantibus. Petalis planis, 

 longitudinis dimidio conjunctis. Ovario dense villoso. Legumen 

 ac semen non vidimus. 



Presumably a shrub, with slender branches, almost terete, 

 and well marked by the decurrent lines of the phyllodes. 



Phyllodia linear-subulate, somewhat weak, slightly 

 flattened, with numerous (about 8) raised ribs or nerves, 

 13 or 14 cm. long, the base swollen with annular markiogs, 

 the apex gradually drawn out into a weak point, the whole 

 sparingly besprinkled with short hairs, but plentifully so 

 towards the base and along the point. 



Stipules short, broad, densely covered with short hairs. 



Peduncles solitary or two together, 1 — 1*5 cm. long, very 

 slender, and more or less besprinkled with hairs, each 

 bearing a rather large globular head of from 24 to 30 flowers, 

 mostly 5-merous.
