jDeduncles, the flowers sometiiiie^^ more than three together, the 

 bracts usually >oinewhat shorter and more pointed. The leaves 

 shorter (about 1cm. long), and the whole plant covered with a 

 more or less well-developed pubescence, the -s^caibrous hairs less 

 developed. 



From 0. strigosa, Benth., it differs in its twenty or more ray 

 florets, equal 23appus and short nonseptata scabrou'> hairs. It 

 bears some resembla)nce to 0. adenolasia (F. v. M.), but is dis- 

 tinguished by its more numerou-s ray florets, larger heads, more 

 pointed ajnd usually coloured bracts. 



Phymatocarpus. (Myrtaceae). 



Tlie leaves of this plant are given as opposite in Bentham's 

 Flora, as in Beaufortia and Regelia. Examination shows that 

 they are all ajlternate in Phymatocarpus, though closely set in 

 P. porphyrocephalus, the bases are all at different levels, and in 

 P. Maxwellii the internodes between the separate leaves are 

 of some length. This gives an easy mode of distinguishing 

 roughly Phymatocarpus from Beaufortia and Regelia. The only 

 exception to the inile of opjD^osite leaves in the last two genera 

 is in Beaufortia squarrosa. This ha« mostly opposite leaves, 

 but in some of the shoots the leaves, though closely set, are 

 alternate, the bases being all at different levels. This is prob- 

 ably an instance of partial reversion to the more primitive type. 



PouoLKPis Spknckki, A. J. E. (Compositae). 



This plant bears a close external resemblance to P. aristata, 

 Benth., Fl. Aust., III., 605, from which, however, the blunt 

 outer bracts, the less deeply lobed ra,y florets, and the flowers 

 white or pale instead of yellow distinguish it. Mr. Max Koch, 

 its discoverer, also informs me that P. spenceri is only found in 

 ■damp places near rivei" flats, whereas P. aristata grows in drier 

 situations.

In all large genera (.Salix, Eucalyptus, Acacia, Rubus, Hierac-
