inflorescence of iii. and iv. is too marked to be classed as varietal, 

 and no one seems to have met with the intermediate forms. 



The structure of the flowers in all the forms is the same, but 

 the female flowers are far more numerous than the males, which 

 are diflicult to detect even in living specimens. 



The results of my investigation.s may perhaps be best shown in 

 the following tabulation : — 



Form i. (fig. 1). — Drawn from material obtained at BalUna, Richmond 

 River, N.S.W. ; it agrees with Oliver's species except in the 

 number of flower-heads, which were found to be in threes in all 

 specimens examined ; a very delicate shrub. 

 N. incanus, Oliv., = N. incanns, F.v.M. 



Foi'm ii. (fig. 2). — Drawn from material obtained near Lismore and Is with- 

 out doubt the N. suhaureus of Oliver. The common peduncle is 

 very variable in length and the upper side of the leaf is distinctly 

 3-nerved ; Oliver's species name is very happily chosen. 

 N. suhaureus, Oliv., = N incanus, F.v.M. 



Form iii, (fig. 3). — From the same locality as previous variety (ii. ), but has 

 larger leaves than i. and ii., and there is a distinct departure from 

 the golden tomentum to a silver sheen. It is also distinctly 

 triplinerved, the transverse veins are distinctly prominent, and 

 the leaf is also of a much thinner texture than forms i. and ii. 

 Safiicient specimens have been examined to show that it is no 

 sport. — Previoiisly unrecorded. 



Form iv. (fig. 4). — A robust shrub, leaves thick, almost fleshy, 3- to 5-nerved, 

 glabrous. The flowers examined have generally been larger than 

 those of Oliver's. Stipules much more pi'ominent than in three 

 previous varieties. Collected in large quantities by me on the 

 ranges south of the Goulburn River, and also at Rylstone. 

 N. cornifolius, Oliv., = N. incamis, F.v.M. 



Form V. (fig. 5).— An extreme form with ovate-lanceolate obtuse leaves; 

 thick in texture, 5-nerved, nearly 4 inches long and 2 inches wide, 

 but in other respects agreeing with N. cornifolius ; stipules very 

 prominent. Lismore, N.S.W. — Previously unrecorded.

 male flower (enlarged) ; d, back and front view of anther detached 

 (enlarged) ; e, seed (nat. size).
