from North Australia and Queensland. Whether the variety is 

 or is not really an independent species is another question.

Derby, a shrub with flowers and unripe fruits (No. 1165, 

 7. Nov. 1914). 



The distinctions given by Bentham (1. c.) between the glabrous 

 variety of P. reticulatus Poir. and P. baccatus F. v. Müll, are not 

 very sharp, and my specimens agree in some respects with the 

 latter species. But as the flowers — both male and female — 

 have short filiform pedicels longer than the perianth, and as the 

 filaments of the stamens are more or less united, I prefer to 

 place my specimens under the widely distributed P. reticulatus, 

 of which, no doubt, several geographical races will be distinguished 

 in future.

Herba basi sublignosa, undique dense stellato-tomentosa; caulis
