Pultenaea humilis, Benth. 

 (Hook, f. Fl., Tasm., i., 91). 



A shrub with flowers like those of P. plumosa, from which 

 species it differs in having bracteoles with broad stipules, and 

 flowers axillary in short leafy spikes at or near the ends of 

 the branches, not in terminal heads. The common Victorian 

 form is low and diffuse, with large flowers, the calyx lobes being 

 much longer than the tube, lower ones much narrower than the 

 upper, all hirsute with long hairs. Bracteoles are linear-lanceolate, 

 ciliate, as long as the calyx lobes, and fixed at the base of the 

 tube. The ovary is glabrous, with a brush of long white hairs 

 at the top, and the style is much dilated. Grampians, Geelong, 

 Ballarat, etc., Vic. 



It appears to be confined to the southern half of Victoria. 



P. humilis, var. glabrescens, var. nova. 



Variat foliis fere glabris, floribus paulo minoribus saepe 

 glabris. 



From the normal this differs in having almost glabrous leaves, 

 and somewhat smaller flowers often quite glabrous. Specimens 

 from Grampians and Creswick, with narrow leaves have fallen 

 wrongly under var. angustifolia of P. parviflora, Sieber, p. 132, 

 Fl., Aust. The Grampians specimens are scantily invested with 

 long hairs on the calyx and bracteoles, while those from Creswick 

 have hairs only on the branchlets and pedicels. Goulburn River 

 specimens (W. F. Gates), have larger, glabrous leaves and hairy 

 branchlets and pedicels. Those from Sale, Vic, (T. A. Robin- 

 son), and Bairnsdale (T. S. Hart), have shorter leaves, broader 

 towards the summit, and smaller flowers. All the specimens
